Answer: Less than one pizza or 4/5 of a pizza
Step by Step Explanation:
If you're trying to give a product with a certain amount and theres more people who want it than the product then it's going to be less than 1; in this equation you would be doing 4 divided by 5 or 4/5 or 0.8.
Explanation for the Teacher: Since there is more people than pizza's then the number is going to be less than 1, then if you want to share 4 pizzas with 5 kids you have to put the pizzas over the kids with fractions and it's 4/5.
Answer:
286.5 days.
Step-by-step explanation:
This is a normal distribution problem with
Mean = μ = 266 days
Standard deviation = σ = 16 days.
Let the number that corresponds to the top 10% be a.
P(x > a) = 0.1
Let the z-score of a be z'
z' = (x - μ)/σ = (a - 266)/16
Using the normal distribution table, we can obtain the z-score that corresponds to z'
P(x > a) = P(z > z') = 1 - P(z ≤ z') = 0.1
P(z ≤ z') = 1 - 0.1 = 0.9
From the tables, z' = 1.282
P(z ≤ 1.282) = 0.9
And P(z > 1.282) = 0.1
1.282 = (a - 266)/16
16 × 1.282 = a - 266
20.512 = a - 266
a = 286.512 days
Hope this Helps!!!
First solve C
Then make 2 equations to use them
X=22.5
4 is bigger than n, so either the second or fourth one
