Answer:

x = -4

Step-by-step explanation:

Given: -2(4x + 4) - 3x - 2 = 34

To solve this equation, we have to isolate the variable. (Get x by itself).

We'll follow the PEMDAS rule as far as parentheses.

So, -2(4x + 4) - 3x - 2 = 34

= -8x - 8 - 3x - 2 = 34

Now, we have to get x by itself. To do this, we'll move the numbers without variables to the other side.

Hence:

-8x - 8 - 3x - 2 = 34

+8 +2 +8 +2

-8x - 3x = 34 + 8 + 2

Now, we'll simplify.

-11x = 44

Lastly, to rid the negative eleven from the x, we have to divide negative eleven by the rest of the equation.

-11x = 44

-11

<h3>Question 3</h3>

Use the equation for exterior angle

<u>Exterior angle = sum of non-adjacent interior angles</u>

5x - 2 = 2x + 76
5x - 2x = 76 + 2
3x = 78
x = 26

For a sample of eight bears, researchers measured the distances around the bears' chests and weighed the bears. Minitab was us

ExtremeBDS [4]

Answer:

There is a linear correlation between chest size and weight,0.8482

Step-by-step explanation:

Given that for a sample of eight bears, researchers measured the distances around the bears' chests and weighed the bears.

the value of the linear correlation coefficient is r = 0.921.

i.e. there is a strong positive correlation from the value of r.

$H_0: r=0\\H_1: r\neq 0$

(Two tailed test at 5% level for correlation coefficient)

Test statistic t = $\frac{r\sqrt{n-2 } }{\sqrt{1-r^2}} \\=5.791$

p value <0.00001

Since p is less than 0.05 we reject H0

a) There is a linear correlation between chest size andweight

b)-- R^2 = 0.8482 proportion of the variation in weight can be explainedby the linear relationship between weight and chest size
