The scores for a certain test of intelligence are normally distributed with mean 85 and standard deviation 11. Find the 90th per
jonny [76]

Answer:

99.1 is the 90th percentile of these scores.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 85

Standard Deviation, σ = 11

We are given that the distribution of score is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

We have to find the value of x such that the probability is 0.90

P( X < x) = P( z < \displaystyle\frac{x - 85}{11})=0.90  

Calculation the value from standard normal z table, we have,  

P(z \leq 1.282) = 0.90

Putting values, we get,

\displaystyle\frac{x - 85}{11} = 1.282\\\\x = 99.1

Thus, 99.1 is the 90th percentile of these scores.

Sam buys 3 pounds of apples for $6. What is the unit rate?
olganol [36]

Answer: 1 pound per $2

Step-by-step explanation:

Imagine this problem as a ratio:

Pounds : Dollars

3 : 6

To simplify this ratio, we see that a common divisor(in fact the only common divisor) is 3.

3/3 : 6/3

1 : 2

Therefore, we get 1 pound per $2

Two numbers are the ratio 3:2. If the smaller number is 24, find the larger number.
erastova [34]
Basically, you try to find 2 numbers that divide to 3/2. So, using trial and error, plug in numbers for x in this expression: x/24=3/2, and solve to find the number that makes it true. You end up getting 36/24=3/2. Hope that helps! :)
