Answer:

Step-by-step explanation:

The two angles are better known as corresponding angles, and since the two lines are parallel, then the angles must be congruent. This means x = 115 degrees.

C. The values of x is 115 because the two angles shown are congruent.

Why the other answers are wrong:

A & B are wrong because it states the two angles are supplementary, but supplementary angles have to add up to 180 degrees and 115+115 is 230 not 180.

D is wrong because there's no logical explanation to why you would subtract 90 degrees from 115 to solve for x.

Q. The probability that a student passes a statistics test is 2/3 and the

kenny6666 [7]

Answer:

4/9 or 44.44%

Step-by-step explanation:

We have the following probabilities:

Probability of winning the statistical test = P (s) = 2/3

Probability of winning the mathematics and statistics test = P (s n m) = 14/45

Probability of winning at least one test = P (s u m) = 4/5

We have that, the probability of winning the mathematics test P (m) can be found in the following way:

P (s n m) = P (s) + P (m) - P (s u m)

replacing we have:

14/45 = 2/3 + P (m) - 4/5

P (m) = 14/45 - 2/3 + 4/5

p (m) = 4/9 = 0.444

Which is the same as there is a 44.44% probability that I will win the math test

Find the remainder when 129 + 1924 is divided by 10.

ZanzabumX [31]

Hey!

Alright let's solve the first part of the equation which is $129 + 1924$ . All we have to do is add it so we find the answer to it.

$129 + 1924 = 2,053$

Now the next step to solving this would be to simply divide it by 10.

2,053 ÷ 10 = 205 R.3

See the image below to see how it's done.

So, this means that when 129 + 1924 is divided by 10 is 205 R. 3

Hope this helps!
