Answer:
0.2755
Step-by-step explanation:
We intend to make use of the normal approximation to the binomial distribution.
First we'll check to see if that approximation is applicable.
For p=10% and sample size n = 500, we have ...
pn = 0.10(500) = 50
This value is greater than 5, so the approximation is valid.

The mean of the distribution we'll use as a model is ...
µ = p·n = 0.10(500)
µ = 50
The standard deviation for our model is ...
σ = √((1-p)µ) = √(0.9·50) = √45
σ ≈ 6.708204

A continuity correction can be applied to better approximate the binomial distribution. We want p(t ≤ 9.1%) = p(t ≤ 45.5). For our lookup, we will add 0.5 to this limit, and find p(t ≤ 46).
The attached calculator shows the probability of fewer than 45.5 t's in the sample is about 0.2755.
Answer:
boys
Step-by-step explanation:
Let = total number of ninth graders. By knowing how many students there are in the grade, we can find for the number of boys.
(number of girls in ninth grade)
To find for the number of boys, we can use substitution:
∴ There are boys in the class.
Hope this helps :)

Answer: She needed to make a cup of jam .
Step-by-step explanation:
Since we have given that
Sarah used pound of blueberries to make
cup of jam.
As we need to find the number of pounds of blueberries she would need to make a cup of jam.
So, we will use "Unitary Method":
Hence, She needed to make a cup of jam .
