The probability of getting 3 black cards out of 4 drawn from a standard deck of 52 cards is approximately 0.253 or 25.3%.
To determine the probability of getting 3 black cards out of 4 cards drawn from a standard deck of 52 cards, we can use the hypergeometric distribution.
There are 26 black cards in the deck, and the total number of ways to choose 4 cards from 52 is given by the binomial coefficient C(52, 4). The number of ways to choose 3 black cards out of 26 is given by the binomial coefficient C(26, 3).
The number of ways to choose the fourth card from the remaining 26 non-black cards is given by the binomial coefficient C(26, 1).
Therefore, the probability of getting 3 black cards out of 4 is:
P(3 black cards) = C(26, 3) * C(26, 1) / C(52, 4)
P(3 black cards) = (2600 * 26) / 270725
P(3 black cards) ≈ 0.253

Find the number of degrees in an angle which is 120 less than its supplement?
The angle in question measures 60 degrees.
What are supplementary angles?
Supplementary angles are two angles that has sum of 180 degrees. In other words, if you have two angles that are next to each other, and when you add them together, they equal 180 degrees, then those angles are considered to be supplementary.
Let x be the measure of the angle in question.
The supplement of an angle is the angle that, when added to the given angle, results in a sum of 180 degrees. So, the supplement of x is 180 - x.
The problem tells us that the given angle (x) is 120 degrees less than its supplement (180 - x).
Therefore, we can set up the equation:
x = (180 - x) - 120
Simplifying this equation, we get:
x = 60

the empirical rule says that 95% of the population is within 2 standard deviations of the mean, but when i find the z-scores that mark off the middle 95% of the standard normal distribution i calculate -1.96 and 1.96. is this a contradiction? why or why not? in other words why are the normal distribution calculators not agreeing with the empirical rule?
The empirical rule states that approximately 95% of the population lies within 2 standard deviations of the mean for a normal distribution, but you found that the z-scores that mark off the middle 95% of the standard normal distribution are -1.96 and 1.96. This does not represent a contradiction, and I will explain why is it so ?
The empirical rule, also known as the 68-95-99.7 rule, is a useful guideline to help us understand the proportions of data in a normal distribution. According to this rule, about 68% of the data falls within 1 standard deviation, 95% within 2 standard deviations, and 99.7% within 3 standard deviations. However, it is essential to note that the empirical rule is a simplified approximation.
On the other hand, the z-scores that you calculated, -1.96 and 1.96, are more precise values based on the actual standard normal distribution. These values come from a more accurate calculation using the cumulative distribution function (CDF) of the normal distribution, which gives the exact probability for any given range of z-scores.

when changes in one variable tend to be accompanied by specific changesin another, the two variables are said to .
The two variables are said to have a correlation.
Correlation is a statistical measure of the relationship between two variables. When two variables are correlated, changes in one will be associated with changes in the other. For example, as the temperature increases, ice cream sales will also increase.
The correlation coefficient is a measure of the strength of the relationship between two variables. If the coefficient is close to +1, there is a strong positive correlation.
This means that as one variable increases, the other also increases. If the coefficient is close to -1, there is a strong negative correlation. This means that as one variable increases, the other decreases. If the coefficient is close to zero, the variables are said to have no correlation.
Correlation does not necessarily imply causation. It only indicates that two variables are related and does not necessarily explain why.
For example, two variables can be correlated because of a third variable. Therefore, correlation does not always indicate a causal relationship between two variables.

at noon, a truck and a car leave the same intersection traveling in the same direction. the truck is traveling at 30 mph and the car is traveling at 42 mph. at what time will they be 9 miles apart?
Considering they left at precise noon, at 12:45 they will be 9 miles apart after they leave the intersection.
Let's call the time it takes for them to be 9 miles apart "t". During this time, the truck will have traveled a distance of 30t, and the car will have traveled a distance of 42t. Since they are traveling in the same direction, we can subtract the distances to find the distance between them:
42t - 30t = 12t
So they are separating at a rate of 12 miles per hour.
To find when they will be 9 miles apart, we can set up the equation:
12t = 9
Solving for t:
t = 9/12
t = 0.75 hours,
To convert 0.75 hours into minutes, we have to multiply it by 60.
= 0.75 × 60
= 45 minutes
So they will be 9 miles apart 45 minutes after they leave the intersection, or at 12:45pm.

a schools class rings can include a student's initials in an engraved monogram on the ring. How many different monograms are possible form 2 sizes, 5 type styles, and 3 boarder styles?
there are 30 different monograms possible, based on the given choices.
A monogram is a design that uses the initials of a person's name, usually in an artistic or decorative way. In the case of school class rings, the monogram is often engraved onto the surface of the ring. The monogram typically consists of the student's initials, with the first initial on the left, the middle initial (if applicable) in the centre, and the last initial on the right.
In this problem, we are given that there are two sizes of initials (presumably a larger size for the first and last initials, and a smaller size for the middle initial), five different type styles (i.e., different ways the letters can be designed), and three different border styles (i.e., different decorative borders around the monogram).
To calculate the total number of possible monograms, we need to multiply the number of choices for each category. This is known as the multiplication principle of counting.
So, we start by considering the number of choices for the initial sizes. We are given that there are two sizes, so there are two choices. Next, we consider the number of choices for the type styles. We are given that there are five different type styles, so there are five choices. Finally, we consider the number of choices for the border styles. We are given that there are three different border styles, so there are three choices.
To get the total number of possible monograms, we multiply the number of choices for each category together. So we get:
2 (initial sizes) x 5 (type styles) x 3 (border styles) = 30
Therefore, there are 30 different monograms possible, based on the given choices.

The length of the base of a parallelogram is 30 feet and the height is 40 feet.
Given that the height of a parallelogram is 10 feet more than the length of the base, and the area of the parallelogram is 1200 square feet. We have to find the length of the base and the height. Let the length of the base of a parallelogram be x. Then, the height of the parallelogram = x + 10.
We know that the area of a parallelogram is given by; A = base × height1200 = x(x + 10). Simplify the equation1200 = x² + 10x. Rearrange the equationx² + 10x - 1200 = 0. On solving this quadratic equation, we get; x = 30 and x = -40.
Since the length of the base cannot be negative, therefore, the length of the base is 30 feet. So, the height of the parallelogram is 30 + 10 = 40 feet. Therefore, the length of the base of a parallelogram is 30 feet and the height is 40 feet.

two marbles are drawn without replacement from a box with 3 white, 2 green, 2 red, and 1 blue marble. find the probability that both marbles are red.
The probability that both marbles are red is 2/14 or 1/7.
This is because there are only two red marbles in the box, so the probability of the first being drawn is 2/14 (or 1/7). Since the first marble is not replaced, the probability of the second being drawn is also 2/14 (or 1/7). Mathematically, this can be expressed as: P(Both Red) = P(Red 1) x P(Red 2) = (2/14) x (2/14) = 1/7
In general, when dealing with probability questions involving drawing multiple objects from a box, the probability of drawing one object followed by another is calculated by multiplying the probability of drawing each individual object.
In the case of two marbles being drawn without replacement, the probability of both marbles being the same color is calculated by multiplying the probability of the first marble being of that color by the probability of the second marble being of that color.
The probability of the second marble being of the same color is lower than the probability of the first marble being of that color since it is drawn from a reduced set (the original set minus the first marble).
In this case, the probability of the second marble being of the same color as the first is 2/14, or 1/7. In conclusion, the probability of both marbles being red is 2/14, or 1/7.

We need to find the limiting factor. We can do that by comparing ratio of mass of ingredient given to mass of ingredient needed for 20 biscuits
[tex]Butter:\\800:150\\=16:3\\=5.33\\Sugar:\\700:75=28:3\\=9.33\\Flour:\\1000:180\\=50:9\\=5.56\\Chocolate Chips:200:50\\=4:1\\=4\\[/tex]
We can clearly see that the choco. chips are the limiting factor since it has the lowest ratio, basically meaning we will run out of choco chips before anything else.
[tex]Biscuits=4*20=80[/tex]
Since we only have 4 times the choco chips needed to make 20 biscuits, we can only make 80 biscuits. Now you can see, we have other ingredients left, but choco chips have ran out which is why it was the limiting factor.

|-2x-5| ≤5
Show it's solution set!
Answer: -5 ≤ x ≤ 0.
Step-by-step explanation:
To solve the inequality, we need to consider two cases:
Case 1: -2x - 5 ≤ 5
Adding 5 to both sides gives:
-2x ≤ 10
Dividing both sides by -2 and reversing the inequality:
x ≥ -5
Case 2: -(-2x - 5) ≤ 5
Simplifying:
2x + 5 ≤ 5
Subtracting 5 from both sides gives:
2x ≤ 0
Dividing both sides by 2:
x ≤ 0
Therefore, the solution set is -5 ≤ x ≤ 0.

the total number of goals scored per soccer match in the english premier league (epl) follows a poisson distribution, with mean 2.768. what is the probability that three or more goals will be scored in a game?
The probability of three or more goals being scored in an EPL match is approximately 0.522, or 52.2%.
To find the probability that three or more goals will be scored in a game, we need to calculate the cumulative probability of the Poisson distribution for x = 3, 4, 5, and so on, up to infinity. This can be written as:
P(X ≥ 3) = 1 - P(X < 3)
where X is the random variable representing the number of goals scored in a match.
To calculate P(X < 3), we can use the Poisson distribution formula:
[tex]P(X = x) = (e^{(-\lambda)} \times \lambda^x) / x![/tex]
where e is the mathematical constant approximately equal to 2.71828, and x! represents the factorial of x.
Using this formula, we can calculate the probabilities of scoring 0, 1, and 2 goals:
[tex]P(X = 0) = (e^{(-2.768)} \times 2.768^0) / 0! = 0.063\\\\P(X = 1) = (e^{(-2.768)} \times 2.768^1) / 1! = 0.174\\\\P(X = 2) = (e^{(-2.768)} \times 2.768^2) / 2! = 0.241[/tex]
To find P(X < 3), we add these probabilities:
P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = 0.063 + 0.174 + 0.241 = 0.478
Finally, we can calculate the probability of scoring three or more goals using the formula we derived earlier:
P(X ≥ 3) = 1 - P(X < 3) = 1 - 0.478 = 0.522 or 52.2%

To find the total number of different dinner special combinations offered by Lewis' Restaurant, you have to use the multiplication rule.
The multiplication rule states that if an event can occur in 'a' different ways and another independent event can occur in 'b' different ways,
then the two events can occur in 'a x b' different ways.
Therefore, the total number of different dinner special combinations offered by Lewis' Restaurant can be calculated as follows:
4 main dishes × 7 vegetables × 1 salad × 1 type of roll= 28 different dinner special combinations
Note that we multiply the number of options for each course because the courses are independent.
This means that the choice of the main dish does not affect the choice of the vegetable, salad, or roll, and vice versa. Therefore, we can multiply the number of options for each course to determine the total number of different dinner special combinations that Lewis' Restaurant offers.

Hence, proved!!Given that the measure of ∠x is 110°, and the measure of ∠y is 59°, find the measure of ∠z.
Answer:
11°
Step-by-step explanation:
The sum of the angles in a triangle is always 180°. Therefore, we can find the measure of ∠z by subtracting the measures of ∠x and ∠y from 180°:
∠z = 180° - ∠x - ∠y
∠z = 180° - 110° - 59°
∠z = 11°
Therefore, the measure of ∠z is 11°
2sin(2x+π÷3)≥√3
[tex]2 \sin(2x + \frac{\pi}{3} ) \geqslant \sqrt{3} [/tex]
with steps
The solution to the inequality 2sin(2x+π/3)≥√3 is:
x ∈ [-π/6, π/3]
What is inequality?
An inequality is a mathematical statement that compares two values or expressions using symbols such as < (less than), > (greater than), ≤ (less than or equal to), ≥ (greater than or equal to), or ≠ (not equal to). Inequalities are used to express relationships between quantities that are not necessarily equal.
To solve the inequality 2sin(2x+π/3)≥√3, we can follow these steps:
Step 1: Subtract π/3 from both sides to get rid of the constant term on the right-hand side:
2sin(2x+π/3) - π/3 ≥ √3 - π/3
Step 2: Divide both sides by 2 to isolate sin(2x+π/3):
sin(2x+π/3) ≥ (√3 - π/3)/2
Step 3: Use the fact that sin(x) is positive in the first and second quadrants of the unit circle to find the interval of x that satisfies the inequality. To do this, we need to find the angles α and β such that sin(α) = (√3 - π/3)/2 and sin(β) = - (√3 + π/3)/2. Then, the solution interval will be:
α/2 - π/6 ≤ x ≤ β/2 + π/6
To find α and β, we can use the inverse sine function on a calculator or look them up in a table. We get:
α ≈ 0.4636 radians
β ≈ 2.6779 radians
Substituting these values into the solution interval, we get:
0.2318 - π/6 ≤ x ≤ 1.3389 + π/6
Simplifying, we get:
-π/6 ≤ x ≤ π/3
Therefore, the solution to the inequality 2sin(2x+π/3)≥√3 is:
x ∈ [-π/6, π/3]

out of a random sample of 1000 dutch men, how many would we expect to be taller than 190 cm (rounded to the nearest whole number)?
The number of Dutch men taller than 190 cm is approximately 100.
The proportion of men taller than 190 cm is estimated using the normal distribution.
We'll be using a normal distribution, which requires the mean and standard deviation of the height data.
The percentage of Dutch men who are over 190 cm tall can be estimated using a normal distribution model.
We must first determine the mean and standard deviation of the heights.
For the population mean and standard deviation, we use the following values.
μ = 181 cm (the mean of Dutch men's heights)
σ = 7 cm (standard deviation)We may now convert the height of 190 cm to a z-score, which is a standard score that represents the number of standard deviations from the mean of the distribution.
The z-score is calculated using the following formula: Z = (X - μ) / σ
where X is the height of 190 cm,
μ is the population mean,
and σ is the population standard deviation.
Z = (190 - 181) / 7 = 1.2857
We look up the percentage corresponding to this z-score in the standard normal distribution table.
Using the table, we can see that the percentage of individuals with a z-score greater than 1.2857 is 0.1003.
We will use this percentage to estimate the number of Dutch men over 190 cm tall in a random sample of 1000 men.0.1003 * 1000 = 100.3
The number of Dutch men taller than 190 cm is approximately 100.
To the nearest whole number, we round this up, and the expected number of men taller than 190 cm in a random sample of 1000 Dutch men is 101.
