Answer:
10cm
Step-by-step explanation:
find the diameter of the circumference of 5cm:
d= c÷3.14
=5cm÷3.14
=1.6cm
Double 1.6cm:
1.6×2= 3.2
Find the new cicumference:
c= 3.14×d
= 3.14×3.2
= 10cm
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

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.
I’m not entirely sure as why you would have to use RQ, but you could use the equation:
tan30=(PR)/45
Solving for PR, you can put 45tan30 into the calculator to get approximately 21.981 units.
19+3.5-5 [ Dividing 7 with 2 yields 3.5].
