\bf{Hello!}

The answer is 140°

Because we can use exterior angle property here

<u>Exter</u><u>ior</u><u> </u><u>angl</u><u>e</u><u> property</u><u> </u><u>:</u> It states that exterior angle is the sum of two opposite interior angles

y = 120 + 20 = 140°

Answer:

140 degrees

Step-by-step explanation:

A triangle's sum of interior angles is 180.

120+20=140

180-140=40

So X= 40.

X and Y are supplementary, so they both add up to 180.

180-40=140

Therefore, Y=140.

A professor gives her 100 students an exam; scores are normally distributed. The section has an average exam score of 80 with a
frozen [14]

Answer:

6.18% of the class has an exam score of A- or higher.

Step-by-step explanation:

When the distribution is normal, we use 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.

In this question, we have that:

\mu = 80, \sigma = 6.5

What percentage of the class has an exam score of A- or higher (defined as at least 90)?

This is 1 subtracted by the pvalue of Z when X = 90. So

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

Z = \frac{90 - 80}{6.5}

Z = 1.54

Z = 1.54 has a pvalue of 0.9382

1 - 0.9382 = 0.0618

6.18% of the class has an exam score of A- or higher.
