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 = 
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
You have to add up the numbers to equal 39....so it's 18+12+9=39
Answer:
2x=-1 or x=-0.5
Step-by-step explanation:
4x-6=10x-3 (-4x)
-6=6x-3 (+3)
-3=6x (divide by 3)
-1=2x
Answer: The inverse is f^-1 (x) = x - 11
The reflection is written as:

And the graph can be seen below.
<h3>
How to get the graph of the reflection?</h3>
Here we have the function:

A reflection across the x-axis is given by:

Then, replacing the function f(x) by the actual equation:

The graph of the function g(x) can be seen below:
