In the diagram below, lines a and b are parallel and cut by transversal, t. If angle 3 is 120 degrees, find the measure of angle

Vlad1618 [11]

Lines a and b are parallel and cut by the same transversal, t. Since we know these lines are parallel, we can find the measure of angle 7 quite easily.

Angles 3 and 7 are corresponding angles, which means that the two angles are in the same relative position. Thus, they are equivalent.

Angle 3 = angle 7 = 120 degrees

The correct answer is C. 120.

Hope this helps!! :)

Assume that the readings on the thermometers are normally distributed with a mean of 0 degrees and standard deviation of 1.00°C.

NNADVOKAT [17]

Answer:

The temperature for P 84 is approximately 1ºC.

Step-by-step explanation:

Problems of normally distributed samples can be 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.

In this problem, we have that:

Assume that the readings on the thermometers are normally distributed with a mean of 0 degrees and standard deviation of 1.00°C. This means that $\mu = 0$ and $\sigma = 1$

This is the temperature reading separating the bottom 84 % from the top 16 %.

This temperature is the value of X when Z has a pvalue of 0.84. This happens at $Z = 1$ .

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

$1 = \frac{X - 0}{1}$

$X = 1$

The temperature for P 84 is approximately 1ºC.
