Answer:

A, D, and F

Step-by-step explanation:

Tiara did multiply and regroup correctly in the first partial product. Tiara did not multiply and regroup correctly in the second partial product. Tiara was not correct when she added her 2 partial products.

Tiara should of got 18,291 but instead she got 16,291.

When she went to the part to multiply 3x4 she didn't add the remaining 2 from the 3x6+2. So if she did 3x4+2 she would of got the number 14 instead of 12 to put down in the second partial product. Which would make the addition part of it as 4,221 + 14070 = 8291 instead of 4,221 + 12,071 = 16, 291

I hope you understand :)

You have to add them all together and times that by 60%, when you get 13.8 that's the answer and to prove it, subtract 23-13.8 and you get 9.2 and that's 40%

Let Z be the standard normal random variable. Use a probability calculator to answer the following questions: What is the probab

Answer:

0.6826 = 68.26% probability Z will be within one standard deviation of average.

Step-by-step explanation:

Normal Probability Distribution

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score 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 p-value, we get the probability that the value of the measure is greater than X.

What is the probability Z will be within one standard deviation of average?

This is the p-value of Z = 1 subtracted by the p-value of Z = -1.

Z = 1 has a p-value of 0.8413.

Z = -1 has a p-value of 0.1587.

0.8413 - 0.1587 = 0.6826

0.6826 = 68.26% probability Z will be within one standard deviation of average.
