Supplementary? Vertical? Complementary? Acute?

liraira [26]

Answer:

A. supplementary

Step-by-step explanation:

Note the angle measurements of BOC. m∠BOC = 90°

Now note that line FC is a straight line, which makes it's measurement = 180°

Subtract 90 from 180: 180 - 90 = 90°

Both are 90°, which, when combined makes a supplementary angle.

marshall27 [118]

Answer:

The predicted life expectancy of men in a country in which the life expectancy of women is 70 years is 65.33 years.

Step-by-step explanation:

The least square regression line is used to predict the value of the dependent variable from an independent variable.

The general form of a least square regression line is:

$\hat y=\alpha +\beta x$

Here,

y = dependent variable

x = independent variable

α = intercept

β = slope

The regression line to predict the life expectancy of men in a country from the life expectancy of women in that country is:

$\hat y=3.73 +0.88 x$

Compute the life expectancy of men in a country in which the life expectancy of women is 70 years as follows:

$\hat y=3.73 +0.88 x$

$=3.73 +(0.88\times 70)\\=3.73+61.6\\=65.33$

Thus, the predicted life expectancy of men in a country in which the life expectancy of women is 70 years is 65.33 years.

In the Central City Grand Prix, out of 30 cars that started the race, 12 of them finished. What percent of the cars finished the

snow_lady [41]

To get the answer we can use proportion.
30----------100%
12-----------x
Cross multiply now
30x=12*100%
30x=1200% /:30 (divide both sides by 30)
x=40% - it's the percentage of cars which finished the race.
100%-40%=60% - it's the answer
