Answer:

The Y-intercept is the Y value when X = 0.

Find the change in X:

-56 to -42 = 14

-42 to -28 = 14

The X value changes by 14.

For every change in X the Y change:

66-58 = 8

58-50 = 8

For X to get from -28 to 0 would be 2 more changes:

-28 +14 = -14

-14 + 14 = 0

2 more changes of Y would be:

50-8 = 42

42-8 = 34

So when X = 0, Y = 34

The Y-intercept would be (0,34)

The sum of three numbers is 81.The first number is 11 less than the second. The third number is 6 more than twice the first. Wha

Sloan [31]

n - the first number

n + 11 - the second number

2n + 6 - the third number

81 - the sum of three numbers

The equation:

n + (n + 11) + (2n + 6) = 81

n + n + 11 + 2n + 6 = 81 <em>combine like terms</em>

(n + n + 2n) + (11 + 6) = 81

4n + 17 = 81 <em>subtract 17 from both sides</em>

4n = 64 <em>divide both sides by 4</em>

n = 16

the largest of the tree numbers is the third number 2n + 6.

Substitute the value of n:

2(16) + 6 = 32 + 6 = 38

Question 5 (4 points) Marijuana was recently legalized in Canada. A recent study reported that at low doses marijuana could have

Makovka662 [10]

Using the coefficient of variation, it is found that students were more variable in their marijuana consumption.

<h3>What is the coefficient of variation of a data-set?</h3>

The coefficient of variation of a data-set is given by the <u>division of the standard deviation of the data-set by the mean of the data-set</u>. The higher the coefficient, the more variable the data-set is.

In this problem, for marijuana consumption, the average was 3.74 and the standard deviation was 1.47, hence:

$CV_m = \frac{1.47}{3.74} = 0.393$

For depression levels, the average was 19.32 and the standard deviation was 3.18, hence:

$CV_d = \frac{3.18}{19.32} = 0.166$

Due to the higher coefficient, students were more variable in their marijuana consumption.
