If point C is inside AvB, then __+m CvB= m AvB

adelina 88 [10]

Answer: OPTION A

Step-by-step explanation:

It is important to remember the "Angle Addition Postulate" in order to solve this exercise.

You have this larger angle:

$\angle AVB$

According to the "Angle Addition Postulate", if the point "C" is in the interior of $\angle AVB$ , then the measure of this angle can be obtained by adding the angle $\angle AVC$ and the angle $\angle CVB$ .

You can observe in the figure that:

$m\angle AVC=39\°\\\\\mangle CVB=23\°$

Then you get that:

$m\angle AVC+m\angle CVB=m\angle AVB\\\\39\°+23\°=62\°$

Therefore, the correct answer is Option A.

michael wittry has been investing inhis roth IRA retirement account for 20 years. Two years ago his account was worth $215,658.

Over [174]

Let's say

a = 215,658

ok... so.. he first lost 1/3 of that

$\bf \textit{\underline{lost} }\frac{1}{3}a\qquad \qquad a-\cfrac{1}{3}a\implies a-\cfrac{a}{3}\implies \cfrac{3a-a}{3}\implies \cfrac{2a}{3}
\\\\\\
\textit{then he \underline{gained} }\frac{1}{2}\textit{ of }\frac{2a}{3}\qquad \qquad \cfrac{2a}{3}+\cfrac{\frac{2a}{3}}{2}\implies \cfrac{\frac{2a}{3}}{\frac{2}{1}}
\\\\\\
\cfrac{2a}{3}+\cfrac{2a}{3}\cdot \cfrac{1}{2}\implies \cfrac{2a}{3}+\cfrac{2a}{6}\implies \cfrac{4a+2a}{6}
\\\\\\
\cfrac{6a}{6}\implies \boxed{a}\implies 215,658$

so, his nickname might just be even steven, because, he ended up with the same original amount after the 1/2 bump.

If AB is parallel to CD and the slope of CD is -5, what sis the slope of AB?

Lady bird [3.3K]

Answer:

The answer is D. -5

Step-by-step explanation:

Since AB is parallel to CD, their slopes are the same. Parallel actually means to have the same slope.

Based on a poll, 67% of Internet users are more careful about personal information when using a public Wi-Fi hotspot. What is

daser333 [38]

Answer:

The required probability is 0.988.

Step-by-step explanation:

Consider the provided information.

Based on a poll, 67% of Internet users are more careful about personal information when using a public Wi-Fi hotspot.

That means the probability of more careful is 0.67

The probability of not careful is: 1-0.67 = 0.33

We have selected four random Internet users. we need to find the probability that at least one is more careful about personal information.

P(At least one careful) = 1 - P(None of them careful)

P(At least one careful) = 1 - (0.33×0.33×0.33×0.33)

P(At least one careful) = 1 - 0.012

P(At least one careful) = 0.988

Hence, the required probability is 0.988.

The result may be higher because of the convenience bias in retrieving the sample. Because the survey subjects volunteered to respond not random.
