Larry bought 12 containers of pasta salad for a school picnic. Each container held the same number of ounces of salad. Students

tester [92]

Answer:

12 p - 8 p, 4p ( 3 - 2)

Step-by-step explanation:

p = equal the number of ounces of pasta salad in one container

then 12 × p = 12 p in 12 containers

the students finished the pasta salad in 8 containers which equals = 8 p

the number of ounces of pasta left = 12 p - 8 p

b) using the distributive property for example a ( b + c) = ( a×b) + (a ×c)

12 p - 8 p = 4p ( 3 - 2)

A normal distribution has a mean of 137 and a standard deviation of 7. Find the z-score for a data value of 121. Incorrect Round

Neko [114]

Answer:

The z-score for a data value of 121 is -2.29.

Step-by-step explanation:

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 137, \sigma = 7$
