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

Step-by-step explanation:
Nash is making a framed enlargement of a Mary Cassatt postage stamp to present to a retired postmaster.
1. The scale of enlargement is 2 inches to 1 centimeter.
2. The actual length of the stamp = 3 centimeters

5. The width of frame = 2 x 5 = 10 inches
Conclusion: Because of this, the dimensions for the scale picture would be 6 by 10 inches
Roots of the equation 3x² -3x-6=0 are -1 and 2,
all choices are given wrong
3*2²-3*2-6=0
12-6-6=0
0=0, which is true , so root is 2
3*20²-3*20-6=0
600-60-6=0
534=0 which is wrong, so root is 2, but not 20
