Hey there!

The answer to your first problem will be a line graph. These graphs represent data in relation to time on individual axes, which will be perfect to represent Karen's temperature data. A circle graph, histogram, and venn diagram will all deal with her data in relation to how often each average occurs, which isn't what she wants to do.

The answer to your second problem will be a histogram. Again, this graph deals with data in relation to how often each point occurs, but will be the best for the interval that Brittany wants to use.

Hope this helped you out! :-)

Answer:

x = 13

Step-by-step explanation:

$a^{2} +b^2 = c^2\\12^2 + 5^2 = c^2\\144 + 25 = c^2\\169 = c^2\\$

Take the square root of both sides

$\sqrt{169} = \sqrt{c^2} \\13 = c$

An art history professor assigns letter grades on a test according to the following scheme. A: Top 13% of scores B: Scores below

madam [21]

Answer:

The numerical limits for a B grade are 81 and 89, that is, a score between 81 and 89 gets a B grade.

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.

Scores on the test are normally distributed with a mean of 79.7 and a standard deviation of 8.4.

This means that $\mu = 79.7, \sigma = 8.4$
