Answer:

B. The angles total 180 degrees.

Step-by-step explanation:

Given that R is equidistant from U and S

It means  UR= SR

In angles UTR and STR

TR is common ray for both angle UTR and STR and T is common vertex .

Linear pair angles:Linear pair angles is a pair of adjacent angles and adjacent angles is supplementary.Adjacent angles  means that angles next to each other. Supplementary angles means that measure  of two angles is 180 degrees.

When two angles are in linear pair then one ray is common in both angles and vertex is common in both angles.

We have  one vertex common and one ray  common in angles UTR and STR.

Therefore , Angles UTR and STR form linear pair

Linea pair means

m\angle UTR+ m\angle STR=180^{\circ}

Hence, sum of angles UTR and STR  is 180^{\circ}.

Suppose that the scores of a history test are normally distributed with a mean of 565 and a standard deviation of 113. a) What p
zvonat [6]

Answer:

15.39% of the scores are less than 450

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.

In this problem, we have that:

\mu = 565, \sigma = 113

What percentage of the scores are less than 450?

This is the pvalue of Z when X = 450. So

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

Z = \frac{450 - 565}{113}

Z = -1.02

Z = -1.02 has a pvalue of 0.1539

15.39% of the scores are less than 450

Which of the following equations has no solution?
daser333 [38]

Answer:

B. 3x+5−4x=−(x+8)

Explanation:

3x+5−4x=−(x+8)

Step 1: Simplify both sides of the equation.

3x+5−4x=−(x+8)

3x+5+−4x=−x+−8

(3x+−4x)+(5)=−x−8

−x+5=−x−8

−x+5=−x−8

Step 2: Add x to both sides.

−x+5+x=−x−8+x

5=−8

Step 3: Subtract 5 from both sides.

5−5=−8−5

0=−13

So, there is no solution

Hope this Helps!

The number line shows the change in temperature from 7:00 a.M. To 1:00 p.M. Which expression shows how to find the difference be
xz_007 [3.2K]

Answer:

B

Step-by-step explanation:

The options in the question and the number line are shown in the image attached.

From the options, it is clear that the difference between the temperatures at 7:00 a.M. and 1:00 p.M is;

Temperature at 7:00 a.M - Temperature at 1:00 p.M

We can see from the number line that the temperature at 7:00 a.M = -4

Temperature at 1:00 p.M = 16

difference between the two temperatures = ∣(-4) - 16∣ = 20
