The answer is C. 

this is because one other angle will be equal to the first angle of 30°

The other two are equal to \frac{360- (30 +30)}{2} =150°

The answer is B. It's B because a straight line has a degree of 180, if you have 2, then of course it becomes 360. In B, you have 90, 90, and 150. If one of the angles is 30, you add that onto 150 to get 180 and add 90 and 90 together to get 180. Naturally, add those two answers together to get 360.

Running at an average rate of 4 meters per second, a sprinter ran to the end of a track. The sprinter then jogged back to the st
yaroslaw [1]
<h2>Length of track is 168 meter</h2>

Step-by-step explanation:

Let l be the length of track.

Running speed = 4 m/s

Jogging speed = 2 m/s

Total time taken = 2 minutes 6 seconds. = 126 seconds

That is

            \frac{l}{4}+\frac{l}{2}=126\\\\0.75l=126\\\\l=168m

Length of track is 168 meter

HURRY PLZ!!!
nasty-shy [4]

Answer:

D) no solution

Step-by-step explanation:

1/ (x-2) + 1/(x+2) = 4/(x^2-4)

x cannot equal 2 or -2 since that would make our fractions equal 1/0 or be undefined

Factor the term on the right

1/ (x-2) + 1/(x+2) = 4/(x-2)(x+2)

Multiply both sides by (x-2) (x+2)

(x-2) (x+2) (1/ (x-2) + 1/(x+2)) = 4/(x-2)(x+2)*(x-2) (x+2)

Distribute

x+2 + (x-2) = 4

Combine like terms

2x = 4

Divide by 2

2x/2 = 4/2

x =2

But this is not a possible solution since that is not in the domain

Calculate the correlation coefficient for the given data below:
Rasek [7]

The correlation coefficient of the data provided is -0.52.

<h3>What is the correlation coefficient?</h3>

Correlation is a measure that is used in statistics to determine the linear relationship that exists between two variables. Correlation can be positive, negative or zero.

Positive correlation is when two variables move in the same direction. Negative correlation is when two variables move in opposite directions. Zero correlation is when there is no relationship between the variables.

Correlation can be determined using a financial calculator. When the financial calculator is used, the correlation coefficient is -0.52
