Answer:

x = -55

Step-by-step explanation:

Subtract 7 on both sides first to get to this equation, x/5 = -11. Since there is a fraction on the left side, you have to multiply 5 on both sides to get your x-value which is -55.

Nine boys share 4 pizzas equally what fraction of pizza does each boy get? Each boys share is blank of pizza

Rudik [331]

so if each pizza has 8 slices in each pie then we can do 8 times 4 which is 32. We can then divide 32 divided by the 9 boys. So the answer would be 3.5. They each had 3 and a half slices of pizza each. The fraction would be 3.5/32

Hope this helps:)

The time to complete the construction of a soapbox derby car is normally distributed with a mean of three hours and a standard d

Bezzdna [24]

Answer:

0% probability that it would take exactly 3.7 hours to construct a soapbox derby car

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

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.

Also, the probability of finding an exact value in the normal probability distribution is 0.
