Step 1:
Distributive property

The equation is now
-2(2x) + -2(-5) = -74

Step 2:
Order of operations; multiply

The equation is now
-4x + 10 = -74

Step 3:
Subtract 10 from both sides

The equation is now
-4x = -84

Step 4:
Divide by -4 on both sides

The equation is now
x = 21

Answer:
21

9) (1 - 6x) + (7x + 3)10) (-4x + 4) – (8x + 7)11) (-x - 3) + (3x + 8)12) (7 + a)-(-7a + 1)14) (-3k - 1) + (7 + 2k)

We solve as follows:

(1-6x)+(7x+3)=x+4(-4x+4)-(8x+7)=-12x-3(-x-3)+(3x+8)=2x+5(7+a)-(-7a+1)=8a+6(-3k-1)+(7+2k)=-k+6

For a data set of brain volumes ​(cm3​) and IQ scores of eight males, the linear correlation coefficient is found and the​ P-val
tatiyna

Answer:

The​ P-value indicates that the probability of a linear correlation coefficient that is at least as extreme is 0.793 which is high so there is not sufficient evidence to conclude that there is a linear correlation between brain volume and IQ score in males.

Step-by-step explanation:

We are given the following information in the question:

p-value = 0.793

Significance level = 0.05

H_{0}: \mu = \text{ The population correlation coefficient is not significantly different from 0}\\H_A: \mu = \text{ The population correlation coefficient is significantly different from 0}

Since p value is greater than the significance value so we fail to reject the null hypothesis and accept the null hypothesis.   We conclude that there is not a significant linear relationship between two variables.

Thus, we can write:

The​ P-value indicates that the probability of a linear correlation coefficient that is at least as extreme is 0.793 which is high so there is not sufficient evidence to conclude that there is a linear correlation between brain volume and IQ score in males.
