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
Its 9 gigabytes because there is 100 megabytes in a gigabyte.
I hope this helps.
So it's asking you to create an expression on how much you spent.
So you have already spent $30 on a DVD and $20 for a CD. And we don't know how much the videos are so that is x.
Your equation is going to be something like 30+20+5x but since it says it wants it in simplest form it's going to be 50+5x or 5x+50 either way that will be your equation answer. The reason it's that equation is because we know how much you spent already which is 50 and since you bought 5 videos of an unknown number that's how you get 5x.
50+5x

Answer:
The surface area of right prism is 12 feet² , option D
Step-by-step explanation:
Given as :
The measure of base = 4 ft
The height of base = 0.5 ft
The surface area of right prism = perimeter of base × height + 2 × base
Now ,
Perimeter of base = 4 + 4 = 8 ft
So, The surface area of right prism = 8 × 0.5 + 2 × 4
Or, The surface area of right prism = 4 + 8
∴ , The surface area of right prism = 12 feet²
Hence The surface area of right prism is 12 feet² . Answer
