Answer:
The linear equation for the line which passes through the points given as (-1,4) and (5,2), is written in the point-slope form as .
Step-by-step explanation:
A condition is given that a line passes through the points whose coordinates are (-1,4) and (5,2).
It is asked to find the linear equation which satisfies the given condition.
Step 1 of 3
Determine the slope of the line.
The points through which the line passes are given as (-1,4) and (5,2). Next, the formula for the slope is given as,
Substitute 2&4 for and
respectively, and
for
and
respectively in the above formula. Then simplify to get the slope as follows,
Step 2 of 3
Write the linear equation in point-slope form.
A linear equation in point slope form is given as,
Substitute for m,-1 for
, and 4 for
in the above equation and simplify using the distributive property as follows,
Step 3 of 3
Simplify the equation further.
Add 4 on each side of the equation , and simplify as follows,
This is the required linear equation.
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
=
the probability that a randomly selected U.S. adult is divorced
= 0.098
