Answer:
C
Step-by-step explanation:
This is a sample proportion where p^ represents the sample proportion.
If we have p^ = 0.6, it means about 60% of the sample are in agreement with or significant to the case study.
The case study here is 'customers that play racquetball' and p^ was 0.16.
This means that 16% of the customers of the sample said they play racquetball.
To find the x-intercept what you do is you plug in zero for Y:
0=4x-8
Then you would add 8 to the left side and x =2
Answer:
y=3-2x
Step-by-step explanation:
Parallel to y = 3 − 2 x => y=c-2x
Through (3,1) => 1=c-2(1) <=> c=3
Line is y=3-2x
Answer:
3 hours.
Step-by-step explanation:
I'm assuming that you are asking how many hours the repairman worked in this problem. To find the solution, use the equation $125=35+ 30x.
Answer:
9 years
Step-by-step explanation:
Let the present age = x
Age 6 years ago = x - 6
Thrice my age 6 years ago = 3*(x -6) =3x - 3*6 = 3x - 18
Twice my present age = 2 *x = 2x
Thrice my age 6 years ago be subtracted from
twice my present age = 2x - (3x - 18)
2x - (3x - 18) = x
2x - 3x + 18 = x
-x + 18 = x {Add x to both sides}
18 = x + x
18 = 2x {Divide both sides by 2}
18/2 = x
x = 9 years
