By using Pythagorean theorem, the shortest distance between planet Q and planet R is 1.25 × 10⁷ kilometers (12.5 million kilometers).

How to find the distance between two planets

The picture shows the geometry between three planets, which represents the three vertices of a right triangle, the straight line distance between the points Q and R represents the hypotenuse of the right triangle. The hypotenuse can be found by using the Pythagorean theorem:

QR = √(PQ² + PR²)

Where QR is the hypotenuse of the right triangle, in kilometers.

If we know that PQ = 3.5 × 10⁶ km and PR = 1.2 × 10⁷ km, then the distance between planet Q and planet R is:

QR = √[(3.5 × 10⁶ km)² + (1.2 × 10⁷ km)²]

QR = 1.25 × 10⁷ km

The measure of the smaller angle is ____
degrees and the measure of the larger angle is ____ degrees.

Answers

Answer:

Step-by-step explanation:

Comment

2 angles are complementary means together they = 90 Degrees.

Let the smaller angle be x

The complement = 3*x - 14  It is the larger angle.

Givens

<1 = x

<2 = 3x - 14

<1 + <2 = 90

Solution

x + 3x -14 = 90              Combine the left

4x - 14 = 90                  Add 14 to both sides

4x - 14+14 = 90 + 14     Combine

4x = 104                       Divide both sides by 4

4x/4 = 104/4

x = 26

A triangle has base 7 m and area 17.5 m². What is the height?​

Answers

Answer: Height = 5m

Step-by-step explanation: To solve the height of the triangle we can use the Area formula and substitute the values given to solve for heigh.

A = ( b * h ) / 2

17.5 = (7 * h) / 2

17.5 (*2) = 7 * h

(Remember that everything done to one side has to be done to both. We can multiply by 2 on both sides to eliminate the 2.)

35 = 7 * h

35/7 = h

5 = h

The height of the triangle equals 5.

All else being equal, if you cut the sample size in half, how does this affect the margin of error when using the sample
to make a statistical inference about the mean of the normally distributed population from which it was drawn?
Z S
ME= √n.

Answers

The margin of error is multiplied by √2.

Given that All else is equal if you cut the sample size in half and to make a statistical inference about the mean of the normally distributed population from which it was drawn ME=(z+s)/√n.

Margin of error (ME) from the mean can be calculated using the formula ME=(z+s)/√n where

z means it is the corresponding statistic of the given confidence level

s means it is the standard deviation of the sample (or of the population if it is known)

N is the sample size

As we know margin of error is proportional with inverse of √N,

If we will cut the sample size in half, the margin of error is multiplied by √2.

Hence, if sample size is cut in half then the margin of error when using the sample to make statistical inferences about the mean of the normally distributed population from which it was drawn is √2.

in a game of poker, what is the probability that a five-card hand will contain (a) a straight (five cards in unbroken numerical sequence)

Answers

The probability that a five-card hand will contain a straight = 5/1274

There are 52 cards in a deck from which each 13 cards are from 4 different suits (clubs, diamonds, spades and hearts) in a game of poker.

Each 13 cards from high to low are Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King. So a straight of five cards, i.e., five cards in unbroken numerical sequence would be got only from 10 cards in a sequence.

So the possible ways to get a single straight five from all four suits = [tex]4^5[/tex]

Now as we doesn't need all 5 cards from a single suit, we can ignore 4 ways from the above number. i.e.,  [tex]4^5-4 = 1020[/tex] ways.

Hence the possible ways to get a straight five from 10 cards from all four suits = 10 x 1020 = 10200 ways

Total number of ways to select 5 cards from 52 cards = 52C5

Thus,

The probability that a five-card hand will contain a straight = 10200 / 52C5

                                                                                                  = 5/1274                        Learn more about probability at https://brainly.com/question/5858025

Answer:

Step-by-step explanation:

Compute the slope of the line through the following points:

p_1 = (1, -1) and p_2 = (-8, -7)

The slope of the line through (x_1, y_1) and (x_2, y_2) is:

(y_2 - y_1)/(x_2 - x_1)

Substitute (x_1, y_1) = (1, -1) and (x_2, y_2) = (-8, -7):

= (-7 - -1)/(-8 - 1)

-8 - 1 = -(8 + 1):

= (-7 - -1)/(-(8 + 1))

8 + 1 = 9:

= (-7 - -1)/(-9)

(-1)^2 = 1:

For the second part, Think of the independent variable as the cause(its value is independent of other variables) and the dependent variable as the effect, essentially the value that depends on changes in the independent variable. In this case it tells you that the perimeter of a square depends on the length, so that means that the length is independent and the perimeter of the square is dependent. So, the dependent variable is the perimeter, because the perimeter of a square depends on the length.

What are linear equations in two variables?

The equations with two variables where each variable has the largest exponent order of 1 having one, zero, or an infinite number of solutions, and are referred to as linear equations in two variables. A linear equation with two variables has the conventional form ax + by + c = 0, where x and y are the variables. Additionally, the answers can be expressed as ordered pairs, like (x, y).

What are forms of linear equations?

Linear equations have three main forms which are as follows:

Y=mx+b, where m is the line's slope and b is the y-intercept, is the formula for slope-intercept form.Ax+By=C is how standard form is expressed, with A, B, and C all being constants.(Y-Y1)=m(X-X1), where m is the slope and (X1, Y1) is a known point on the line, is how the point-slope form is expressed.

We will consider x on the graph to be years since 1986 and y on the graph to be the number of Moose.

We have two points on the graph:  (6, 5200) and (11, 7100)

Using the slope formula m = (y2 - y1)/(x2 - x1), we can find the slope of this line:

m = (y2 - y1)/(x2 - x1)                

m = (7100 - 5200)/(11 - 6)          

m =  1900/5                            

m = 380                                  

Now, that we have the slope of the line, we can use the point-slope formula (y - y1) = m(x - x1) to find the equation for the line.  Here, we're using the first point, but either point will produce the same answer.

(y - y1) = m(x - x1)                                    

y - 5200 = 380(x - 6)                            

y - 5200 = 380x - 2280                            

y - 5200 + 5200 = 380x - 2280 + 5200    

y = 380x + 2920                                    

Since the equation that is being sought is supposed to be in terms of P and t, We will replace y with P and x with t.

Hence, the equation will be P(t) = 380t + 2920.

Answers

180ML of 50% solution are needed.

What is a solution?

Finding an equation's solutions, which are values (numbers, functions, sets, etc.) that satisfy the equation's condition and often consist of two expressions connected by an equals sign, is known as solving an equation in mathematics. One or more variables are identified as unknowns when looking for a solution. An assignment of values to the unknown variables that establishes the equality in the equation is referred to as a solution. To put it another way, a solution is a value or set of values (one for each unknown) that, when used to replace the unknowns, cause the equation to equal itself. Particularly but not exclusively for polynomial equations, the solution of an equation is frequently referred to as the equation's root.

EXPLANATION : To solve this question, we have initial stock solution of 10% and 50% concentration. We need to make final solution of 25% concentration of volume 16oz. [tex](1oz \approx 30ml)[/tex]

To find :- Volume of 50% required

Let us assume we require x oz volume of 50% stock Solution , Then volume of 10% stock added will be (16-x) oz.

Formula used here:-   C1V1 + C2V2 = C3V3

Where C1 = 50% = 0.5 , V1 = x oz    &   C2 = 10%= 0.1  , V2= 16-x oz

C3 = 25% = 0.25 ,  V3= 16oz

Putting values we have

(0.5*x) + (0.1(16-x)) = 16*0.25

0.5x + 1.6 - 0.1x = 4

x = 6

Hence Volume of 50% solution = x = 6 oz = 6*30 ml  = 180ml

b) The equation of the relationship between the distance traveled by the backpacker and time taken is equal to s = (6 / 5) · t.

How to analyze linear equations

According to the image attached aside, we find that the distance traveled by the backpacker (s), in miles, is directly proportional to the time taken (t), in hours. In other words, we have the following relationship:

s ∝ t

s = k · t      (1)

Where k is the constant of proportionality, in miles per hour.

a) The meaning of the point (t, s) = (5, 6) is that the backpacker travels a distance of 5 miles in 6 hours.

b) To determine the equation of the relationship, we need to calculate the constant of proportionality. If we know that t = 5 h and s = 6 mi, then the equation of the relationship is:
