Answer:
(a) 0.5899
(b) 0.9166
Step-by-step explanation:
Let X be the random variable that represents the height of a woman. Then, X is normally distributed with
= 62.5 in
= 2.2 in
the normal probability density function is given by
, then
(a) 
= 0.5899
(in the R statistical programming language) pnorm(63, mean = 62.5, sd = 2.2)
(b) We are seeking 
where n = 37. 
is normally distributed with mean 62.5 in and standard deviation 
. So, the probability density function is given by
, and
= 0.9166
(in the R statistical programming language) pnorm(63, mean = 62.5, sd = 2.2/sqrt(37))
You can use a table from a book to find the probabilities or a programming language like the R statistical programming language.
The answer is 122/495. Hope this helps!
Answer:
around 1.3
Step-by-step explanation:
Answer:
1 is 28 as it is just asking the area (At least I think)
2 is 22 as it is perimeter
Step-by-step explanation:
4x7 is 28 (For one)
8 (4+4) + 14 (7+7) = 22
Have a great day!
Answer:
Yes the y value an have more than one x value BUT the x value can only have one y value.
Step-by-step explanation:
example if we have 1 and it goes to 2 the 1 cant go to another number such as 3.. if we had another number like 4 and it goes to 2 like the 1 it would be acceptable
hope this helped and is not to confusing-
