Answer: We have been given two inequalities and . We are asked to find the integers that satisfy both inequalities.

Step-by-step explanation:

Let us solve for our 1st inequality.

2x + 9 - 9 < 0 - 9

2x< -9

2x/2 < -9/2

X< -4.5

Upon combining our both inequalities, we will get:

-12 < x < -4.5

This means that solution of our inequalities is x values greater than -12 and less than -4.5

We know that integers between and are: -11, -10, -9, -8, 7, -6,-5.

Therefore, our solution would be X= {-11,-10,-9,-8,7,-6,-5}

The heights (in inches) and pulse rates (in beats per minute) for a sample of 40 women were measured. Using technology with the
Viktor [21]

Answer:

There is not sufficient evidence  to support the claim that there is a linear correlation between the heights and pulse rates of women

Step-by-step explanation:

The correlation coefficient between the variables h(height in inches) and pulse rates (in beats per minute) is 0.202

Sample size n=40

Level of significane alpha = 0.01

Create null and alternate hypothesis as:

H0: r=0

Ha: r not equal 0

(Two tailed test at 1% significance level)

Sample r = 0.202

r difference = 0.202

test statistic t = \frac{r\sqrt{n-2} }{\sqrt{1-r^2} } \\=\frac{0.202(\sqrt{38} )}{\sqrt{0.9592} } \\=\frac{1.25}{0.9794} \\=1.271

df =n-2 =38

t critical value for 0.01 and df =38 is 2.704

Since our test statistic lies below 2.704, we accept null hypothesis

There is not sufficient evidence  to support the claim that there is a linear correlation between the heights and pulse rates of women
