Answer:
Number of person use more than 15 hours per week from 800 subscribers = 448
Step-by-step explanation:
Given:
Total number of sample = 50
Result = 28 Person use more than 15 hours per week
Find:
How many people use more than 15 hours per week
Computation:
⇒ Probability of Person use internet more than 15 hours per week = 28 / 50
⇒Probability of Person use internet more than 15 hours per week = 0.56
⇒Number of person use more than 15 hours per week from 800 subscribers = 800 × Probability of Person use internet more than 15 hours per week
⇒Number of person use more than 15 hours per week from 800 subscribers = 800 × 0.56
⇒ Number of person use more than 15 hours per week from 800 subscribers = 448
Answer:
y + 9 = - 2(x - 9)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (9, - 9) and (x₂, y₂ ) = (- 2, 13)
m = 
= 
= - 2
Using (a, b ) = (9, - 9 ) , then
y - (- 9) = - 2(x - 9) , that is
y + 9 = - 2(x - 9)
Answer:
Draw a graph which joins the points (100, 135) and (500, 375) and has a slope = 0.6
The ordered pairs are: (100, 135) and (500, 375)
The first number is the number of minutes of usage and the second number is the charge of the month.
The slope is: ( 375 -135) / (500 - 100) = 240/400 = 0.6
