Answer: 12x^2 - 13x - 14

Choice D

==========================================

Work Shown:

Let y = (3x+2)

Replace (3x+2) with y and we go from (3x+2)(4x-7) to y(4x-7)

Distribute this y through: y(4x-7) = 4xy - 7y

--------------

Now replace y with (3x+2), distribute again, and simplify

4xy - 7y

4x(3x+2) - 7(3x+2)

4x(3x)+4x(2) - 7(3x) - 7(2)

12x^2 + 8x - 21x - 14

12x^2 - 13x - 14

In a sample of 800 U.S. adults, 218 dine out at a restaurant more than once a week. If two U.S adults are selected at random fro
andre [41]

Answer: 0.074

Step-by-step explanation:

Given : The total number of U.S. adults in the sample = 800

The number of U.S. adults dine out at a restaurant more than once a week = 216

The probability for an adult dine out more than once per week :-

\dfrac{218}{800}

If another person is selected without replacement ,then

Total adults left = 799

Total adults left who dine out at a restaurant more than once a week = 217

The probability for the second person dine out more than once per week :-

\dfrac{217}{799}  

Now, the probability that both adults dine out more than once per week :-

\dfrac{218}{800}\times\dfrac{217}{799}=0.074

How do I convert 0.4 into 1/250 how would I explain it???
Tatiana [17]
The decimal number 0.4 is equivalent to 4/10 in fraction form. This fraction can be reduced to its simplest form by dividing both the numerator and the denominator by their greatest common factor (GCF). The GCF of four and 10 is two. Therefore, 0.4 is equal to 2/5.

Bank robber holds up a bank and speeds off at 71 mph. Police start chasing him 10 minutes later going 78 mph. How long will it t
alexira [117]

Answer:

It takes 1.68 hours to catch up to them.

Step-by-step explanation:

The speed of robber = 71 mph

The  speed of police =  78 mph

The police  start 10 minutes  later

by that time robber would have travelled

distance  = \frac{speed}{time}

10 minutes  =0.166667 hours

then the distance  =  11.8 mph

Let them meet at distance x from the bank.

time taken by police to reach x , time =\frac{ x}{78}----------------------(1)

time taken by robber in the same time = \frac{x-11.8}{71}---------------(2)

Equating (1) and (2)

\frac{x}{78} =\frac{ x-11.8}{71}

71 x = 78(x - 11.8)

71x =78x - 920.4

920.4 = 78x - 71x

920.4 = 7x

x = 131.48

The distance where they catch up with the robber from the bank is 131.48 miles

speed of police = 78 mph

distance =  131.48  miles

time they catch up = \frac{131.48}{78}

= 1.68 hours

If the<br> average (arithmetic<br> mean) of 2, 7, and x is 12,<br> what is the value of x?
stealth61 [152]

Answer:

x = 27

Step-by-step explanation:

mean is calculated as

mean = \frac{sum}{count}

sum = 2 + 7 + x = 9 + x and count = 3 , then

\frac{9+x}{3} = 12 ( multiply both sides by 3 to clear the fraction )

9 + x = 36 ( subtract 9 from both sides )

x = 27
