A teacher is assessing the correlation between the number of hours spent studying and the average score on a science test.

The table below shows the data:
(Table In Image)

Part A: Is there any correlation between the number of hours students spent studying and the score on the science test? Justify your answer.

Part B: Write a function which best fits the data.

Part C: What does the slope and y-intercept of the plot indicate? ​

A Teacher Is Assessing The Correlation Between The Number Of Hours Spent Studying And The Average Score

Answers

Answer 1

yes there is a a correlation

f(x) = 4x + 60

slope = 4

y-intercept = 60

Answer 2

There is a correlation between the number of hours spent on studies and the score on music test.

How to explain the correlation?

As we increase the 0.5 hour on studying, then the music score increases by 2. The function which best fits the data for the correlation is y=60 + 4x

The slope and y-intercept of the plot indicate? that Y= score obtained in music test and X=number of hours spent on studying. The slope of the above equation represent the rate of increase in music score with respect to an increase in the number of hours spent on studying.

The y-intercept gives the music score when the number of hours spent on studying is zero.

Answer:

7/6

Step-by-step explanation:

In order to find slope when you have two ordered pairs, you use this equation: (y2-y1)/(x2-x1)

In this case, when you plug them in, you get (49-7)/(42-6), which is 42/36, which is 7/6.

How do solve this question? Find an equation of a line parallel to the given line and contains the given point. Write the equation in slope–intercept form. With the equation 2x + 5y= -10 point (10, 4).

Answers

Answer:

y = -2/5 x + 8

Step-by-step explanation:

First we need to find the slope of the given line;

Given the line 2x + 5y= -10, we need to write it in standard form of y = mx+c

Make y the subject of the formula;

2x + 5y= -10

5y = -2x-10

y = -2x/5-10/5

y = -2x/5 - 2

Hence the slope of the line m = -2/5

Since the equation of the line we need is parallel to this line, hence they will have the same slope.

The slope of the required line = -2/5

Get the intercept;

Substitute the point (10,4) and m = -2/5 into the equation y = mx+c

4 = -2/5(10)+c

4 = -4 + c

c = 8

Get the required equation;

y = mx+c

y = -2/5 x + 8

Hence the equation of a line parallel to the given line and contains the given point is y = -2/5 x + 8

Answers

Answer:

Slope: 4

Y-interecept: -2

Step-by-step explanation:

To find the slope, use rise over run. Go up from the y-intercept and over until you hit another exact point.

To find the y-intercept, just find the point that is on the y-axis.

y intercept is -2 and the slope is 3

Which proportion would be used to solve the following problem. The proportion of turtles to alligators at the reptile park is 5:9. Since Beth counted 45 turtles, how many alligators are there?

Answers

Answer:

befor i go im trynna love you baby hopefully e

Step-by-step explanation:

Answer/Step-by-step explanation:

There are 81 Alligators.

The original equation was 5:9. Since the 5 turtles have been scaled up(multiplied by) 9 times. The rate for alligator will be multiplied by 9.

45 ÷ 5 = 9

9 x 9 = 81

5:9 x 9 = 45:81

Celia wants to buy three shirts, which were originally priced $56 each. The store will
discount the price of the third shirt and then apply a 7% tax to the total cost of all
three shirts. Including the tax, what will be the mean cost of each shirt? (Round your
answer to the nearest cent).
Including the tax, the mean cost of each shirt is $

Answers

Answer:

$49.93

Step-by-step explanation:

Original cost = $56

Cost of 3 shirts:

3*$56 = $168

Cost of 3 shirts with discount:

168 - 1/2*56 = 168 - 28 = $140

Add tax:

$140*1.07 = $149.8

Mean cost of each shirt:

$149.8/3 = $49.93

The question of the pic was cut off at the top and it says -

Line W is graphed on the coordinates plane below.

Answers

Answer: A

Explanation:

Step 1: Use the linear graph to create an equation using slope-intercept form. The y-intercept is (0,-6) because that's where the line passes the y-axis. The slope is 1/2 and that's pretty self-explanatory if you know how to find slope. The equation would be y=1/2x-6.

Step 2: Because we are looking for a line perpendicular to the linear graph, the y-intercept and slope needs to be different. If they're perpendicular, they need to intersect, so the slope needs to be the reciprocal of the original slope, 1/2. The reciprocal is -2. Your equation would be y=-2x+b, and since we don't know the y-intercept, we would leave it as b.

Step 3: Plug in the given ordered pair, (-3,-2), to get -2=-2(-3)+b. You would result with -2=6+b. Subtract 6 to both sides and you would get b=-8.
