The truck can cover 145 miles in 2.5 hours, so the speed of the truck is 
145÷2.5=58 miles per hour
the car's speed is 1.5 times faster: 58×1.5=87 miles per hour
suppose in x hours they will meet:
distance covered by truck in x hour: 58x
distance covered by car in x hour: 87x
total distance: 145 miles
58x+87x=145
x=1

Your reminder would be 32.

Sorry if my graph of synthetic division is a bit messy, you can only do so much on a phone!

Answer: (C) the 2633 viewers who phoned in.

Step-by-step explanation:

In statistics , a sample is a countable subset of a large population that represents the entire population.

Given : A television station is interested in predicting whether or not voters are in favor of an increase in the state sales tax.

It asks its viewers to phone in and indicate whether they support or are opposed to an increase in the state sales tax in order to generate additional revenue for education.

Of the 2633 viewers who phone in, 1474 (55.98%) are opposed to the increase.

i.e. 1474 out of 2633 viewers opposed to the increase.

Clearly , 2633 viewers are representing the entire population of viewers.

Hence, the sample obtained is the 2633 viewers who phoned in.

garik1379 [7]
I do not have a video but to convert a fraction to a decimal, you divide the numerator by the denominator or make the denominator equal to one hundred. For example, to convert 1/5 to a decimal, you write 1/5 as 20/100, which as a decimal is written as .2
