At a constant speed of 55 mph, the distance traveled is directly proportional to the time of travel, d = 55t. if a car travels at 55 mph for 3 hours, how many miles does it go? a. 192.5 b. 275 c. 550 d. 165

d=55(t)   d=55(3) d=165 the answer is D. 165

it costs $20 to interview each person for a survey. find the cost to obtain a +- 3% margin of error.

step-by-step explanation:

copy and paste, put it in google

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
