Answer:

Solve for X-B(5,0.85), for x = 3.*25*

delete my question if it's wrong

The value of the expression is,

X = 0.138

We have to give that,

An expression is,

⇒ X ~ B (5, 0.85)

for, x = 3

Now, simplify the expression for x = 3 as,

X = ⁵C₃ (0.85)³ (1 - 0.85)³⁻¹

X = (5!/3!2!) (0.85)³ (1 - 0.85)²

X = 10 × (0.85)³ (0.15)²

X = 0.138

Hence, The value of the expression is,

X = 0.138

Answer:

The probability that event B will occur is 0.45

Step-by-step explanation:

Given;

probability that event A occurs, P(A) = 0.4

the probability that events A and B both occur, P(A ∩ B) = 0.25

the probability that either event A or event B occurs, P(A ∪ B) = 0.6

To determine the probability that event B will occur, we use probability addition rule;

P(A) + P(B) = P(A ∩ B) + P(A ∪ B)

0.4 + P(B) = 0.25 + 0.6

0.4 + P(B) = 0.85

P(B) = 0.85 - 0.4

P(B) = 0.45

Therefore, the probability that event B will occur is 0.45

Each video gets an average of 1,500,000 views.

A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.

Given:

Each video gets an average of 1,500,000 views

Video get Views = 3 x 1,500,000

                            = 4,500,000 Views

Total Views = 90,000,000 Views

Number of months  = Total Views/Views per month

Number of months  =  90,000,000 / 4,500,000

                                 =  20 Months

Hence, For 20 Months Dagogo need to upload videos to get 90,000,000 views on his channel.

Answer:

y = 1/4x + 5

Step-by-step explanation:

Here, we want to write the equation of the function

Generally we can have the equation of a straight line as;

y = mx + b

m is slope, b is the y-intercept

From the graph we have the y-intercept as 5

To get the slope, we select any two points and apply the slope formula

Let us have the points;

(8,7) and (4,6)

the slope will be;

m = (y2-y1)/(x2-x1) = (6-7)/(4-8) = 1/4

So the equation of the line is;

y = 1/4x + 5

Answer:

The answer is 7.4

Step-by-step explanation: I don’t really know a better way to tell you the explanation than just tell you the answer

The simplified expression is 7 3/5 or 7.6.

To simplify the expression using the order of operations (also known as PEMDAS), follow these steps:

Step 1: Simplify within parentheses (if any).

There are no parentheses in the expression, so we move to the next step.

Step 2: Perform multiplications and divisions from left to right.

First, let's divide 15 by 5:

15 ÷ 5 = 3

Step 3: Perform additions and subtractions from left to right.

Now, let's add 4 3/5 and 3:

4 3/5 + 3

To add the whole numbers, 4 and 3, we get 7.

To add the fractions, we need a common denominator. The common denominator of 5 and 1 is 5. Converting both fractions to have a denominator of 5:

4 3/5 + 3 = 4 3/5 + 15/5

Now, we can add the fractions:

4 3/5 + 15/5 = (4*5 + 3 + 15) / 5

             = (20 + 3 + 15) / 5

             = 38/5

Step 4: Express the result in mixed number form (if necessary).

38/5 can be expressed as a mixed number by dividing the numerator (38) by the denominator (5). The quotient is the whole number, and the remainder is the numerator of the fraction:

38 ÷ 5 = 7 with a remainder of 3

Therefore, the simplified expression is 7 3/5, which is equivalent to 7.6 as a decimal.

10) Sin(33) = x÷29

Multiply with 29 on both sides.

x = Sin(33) × 29 = 15,794

11) Tan(55) = 29÷x

Multiply with x on both sides.

xTan(55) = 29

Answer:

$17,100

Step-by-step explanation:

Set up an equation where y is the worth of the car and t is the number of years since 2010:

y = 26000(0.9)^t

Plug in 4 as t, since it is asking about 2014:

y = 26000(0.9)^t

y = 26000(0.9)^4

y = 17058.6

Round to the nearest hundred dollars:

17058.6

= 17,100

So, the car will be worth approximately $17,100

Answer:

The answer is 7600 because in order to reach negative coordinates you have to travel the length to 0 then down the scale to -1, -2, -3, and so on and vice versa to get to positive coordinates.

Answer:

Down 4 unit (see discussion, could be right 4 units)

G(x) = x - 4

Discussion:

or g(x) = f(x) - 4 = x -4    ... shift down 4 units

Answer:

the midline is the line:

y = 0.

Step-by-step explanation:

The midline of a function is a horizontal line that divides evenly the graph of the function in two parts.

Particularly, for trigonometric functions, we usually have:

f(x) = A*sin(k*x + p) + M

Where:

A is the amplitude.

x is the variable

k is a constant related to the frequency of the function.

p is a phase shift

M is the midline of the function, which means that the line that divides evenly the graph is y = M.

For our case, we have:

y = f(x) = 3*sin(2*x - π)

Then:

A = 3

k = 2

p = -π

And we do not have a constant term in that equation, this means that:

M = 0

This means that the line that divides evenly the graph is the line y = 0.
