Answer:

m<3 = 70 and m<4 = 110

Step-by-step explanation:

<3 and <4 are vertical angles so they add up to 180

(3y + 7) + (5y + 5) = 180

(3y + 5y) + (7 + 5) = 180

8y + 12 = 180

-12 -12

8y = 168

/8 /8

y = 21

find the angle measures:

3(21) + 7

63 + 7

70

5(21) + 5

105 + 5

110

Is it parallel or is it perpendicular?
zavuch27 [327]
It is parallel, which means that the new line should have the same slope of the given line y=-5/4  x+7
and the slope is the coefficient of x 
so the slope = -5/4
in order to solve this problem we have to know the equation of the slop
slope=  \frac{y-y1}{x-x1}
where (x1,y1) is the point by which the new line passes through 

\frac{-5}{4}=\frac{y-(-4)}{x-1}
\frac{-5}{4}= \frac{y+4}{x-1}
-5(x-1)=4(y+4)
-5x +5=4y+16 (by subtracting 16 from both sides)
-5x -11= 4y (divide both sides by 4)
y= \frac{-5}{4}x - \frac{11}{4}

When filling out the 2000 Census, people could choose one of four options to describe their marital status. Data from the 2000 C
galben [10]

Answer:

0.098

Step-by-step explanation:

Given that when filling out the 2000 Census, people could choose one of four options to describe their marital status.

Data from the 2000 Census were used to compute the following probabilities

Marital status Never married Married widowed Divorced total

Prob           0.239          0.595      0.068     0.098 1

Actually we were not given probability for divorced but using total probability =1 we arrived at the probability for divorced as

1-sum of the remaining probabilities

=1-0.239-0.535-0.068\\=0.098

the probability that a randomly selected U.S. adult is divorced

= 0.098
