Answer:
x = -2
Step-by-step explanation:
The x coordinate of the midpoint is found by adding the x coordinates together and dividing by 2
( -4+0)/2 = -4/2 = -2
The y coordinate of the midpoint is found by adding the y coordinates together and dividing by 2
( 8+10)/2 = 18/2 = 9
Step-by-step explanation:
Equ of line -
y=mx+c
Using point (3,-1)
3 as x, - 1 as y
M=2/3
Substitute the values of these coordinates
3=2/3(-1) +c - - - - now find for c
c= 3- (-2/3)
c= 3.67
Now with the value of c, put the values back into the equation form .. Assuming we don't have a point to work with
y=2/3x + 3.67
that's a point slope form so
y +5 = 2(x -4)
Answer:
A) 0.20
B) 0.06
Step-by-step explanation:
From the question above we have the following information;
30% of the residents of a particular town read the morning paper
Probability (of the residents that read morning paper) = 0.3
25% read the afternoon paper
Probability (of the residents that read afternoon paper) = 0.25
10% read both
Probability (of the residents that read both) = 0.10
A. One resident is randomly selected. What is the probability that this person reads only the morning paper?
Probability( that this person reads only the morning paper) = Probability (of the residents that read morning paper) - Probability (of the residents that read both)
= 0.30 - 0.10
= 0.20
B. Given that a random resident reads the morning paper, what is the probability that this resident also reads the afternoon paper?
Probability( that this resident also reads the afternoon paper) = Probability (of the residents that read morning paper) × Probability (of the residents that read afternoon paper)
= 0.30 × 0.20
= 0.06
