Q5 - 6: I'm guessing that it's asking us how many less than right angles, right angles, or more than right angles are present in the shapes given in question 5 and 6.
Keep in mind that right angles are exactly 90 degrees. Less than a right triangle is less than 90 degrees ( x < 90) and more than a right triangle is more than 90 degrees (x > 90) View the attachment for further demonstration and explanation.
Based on this, I think you (or your sister) need to re-check question 5. There are no right angles present there, and the lack of the box and L shaped angles indicate this. You are on the right track for number 6 though as only 2 right triangles are present.
For number 8, Kaylee (lol, feels weird saying that since my name is Kaylee), is incorrect. There are no right angles. You can further explain and elaborate on this using the information I supplied you with.

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.
