Answer: a and b, so the first option
Step-by-step explanation:
It can’t be anything that has to do with C because d is the transversal.
Question options :
a. They should be between 64 and 76 inches tall.
b. They should be close to the height that is 95% of the mean. That is, 66.5 inches, plus or minus 2 standard deviations.
c. They should be at or below the 95th percentile, which is 74.92 inches.
d. None of the above.
Answer: a. They should be between 64 and 76 inches tall.
Step-by-step explanation:
Given the following :
Assume men's height follow a normal curve ; and :
Mean height = 70 inches
Standard deviation= 3 inches
According to the empirical rule ;
Assuming a normal distribution with x being random variables ;
About 68% of x-values lie between -1 to 1 standard deviation of the mean. With about 95% of the x values lying between - 2 and +2 standard deviation of mean. With 99.7% falling between - 3 to 3 standard deviations from the mean.
Using the empirical rule :
95% will fall between + or - 2 standard deviation of the mean.
Lower limit = - 2(3) = - 6
Upper limit = 2(3) = 6
(-6+mean) and (+6+ mean)
(-6 + 70) and (6+70)
64 and 76
4 because none of the dots are on the same line in that one. To figure out if a problem is a function you can do the pencil test and just go across the graph and if the dots are on the same line they wouldn't be a function. I'm not good at explaining but you could look it up and it'll help you more but the answer to this is 4.
Answer:
C = 2πr = dπ
Step-by-step explanation:
given radius r, the circumference is
2πr, derived from the fundamental theorem of calculus
since diameter d = 2r the circumference is also dπ
Hey there!
2 1/4 = 9/4
3 1/2 = 7/2
9 x 7 = 63
4 x 2 = 8
= 63/8
Simplifying 63/8 . . .
63/8 = 7 7/8
2 1/4 * 3 1/2 = 7 7/8
Area = 7 7/8
I hope this helps you!
