1. Start with y=sx+m and input the slope of the line given, because the two lines are parallel they have the same slope. Then input the X and Y coordinates of point X to get 10=-1/2-5+m and finally solve the equation to get m=-7.5 or -15/2 making slope intercept form Y=-1/2-5-15/2
2. Follow the same instructions imputing 1/2 in as the slope because it is perpendicular to the line. so you get 10=1/2-5+m. solve to get m=7.5 or 15/2 making the final equation Y=1/2X+15/2
Answer:
The probability that exactly 2 out of the first 10 customers buy a magazine
=
1.92%
Step-by-step explanation:
The Proportion of customers who buy a magazine = 9.6%
If 2 out of the first 10 customers buy a magazine, the proportion is given as 2/10 or 20%.
Therefore, the probability that exactly 2 out of the first 10 customers will buy a magazine is equal to the proportion of customers who buy a magazine multiplied by the proportion of the first 10 customers who buy a magazine
= 9.6% * 20%
= 1.92%
Answer:
12 cm
Step-by-step explanation:
multiply 10 by .2
10 × .2 = 2
add 2 to 10
2 + 10 = 12 cm
Answer D because you can clearly see the pattern.
