Answers
Using sampling concepts, it is found that the sample is given by:
C. The 150 businesses who were sent surveys.
What is sampling?It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which is a group containing elements of a population. A sample has to be representative of the population, that is, it has to involve all segments of the population.
In this problem, a group of 150 businesses(sample) is taken from the telephone listings(all the businesses in the listings is the population), hence option C is correct.

Answer:
3.9x+0.8y
Step-by-step explanation:
4x−5.2y+6y+7.9x−8x
Combine −5.2y and 6y to get 0.8y.
4x+0.8y+7.9x−8x
Combine 4x and 7.9x to get 11.9x.
11.9x+0.8y−8x
Combine 11.9x and −8x to get 3.9x.
3.9x+0.8y
It can also be converted to fraction form:

A car is traveling at a steady speed. It travels 1 1/2 miles in 2 1/4 minutes. How far will it travel in 46 minuets? In 1 hour?
Answers
Answer:
30.667, in 1 hour = 40 miles
Step-by-step explanation:
Set up a proportion so 1.5 miles / 2.25 minutes.
So 1.5/2.25 = x/46
solve for x 1.5(46)/2.25 = x so x = 30.667
In one hour is 60 minutes so 1.5(60)/2.25 = x

Answer:
=13/3
Step-by-step explanation:
1. Distribute
3+2(4−6)=8+1
3+8−12=8+1
2. Combine like terms
3+8−12=8+1
11−12=8+1
3. Add 12 to both sides of the equation
11−12=8+1
11−12+12=8+1+12
4. Simplify
11=8+13
5. Subtract 8x from both sides of the equation
11=8+13
11−8=8+13−8
6. Simplify
3=13
7. Divide both sides of the equation by the same term
3=13
3x÷3=13÷3
8. Simplify
If you cancel terms that are in both the numerator and denominator you will get:
=13/3

PLS RESPOND ASAP I NEED THE ANSWER PLSSSS
Answers
Answer:
124.8 Inches
Step-By-Step
1/2 0.835 Inches = 0.4175
r = 0.4175
h = 0.077
A=2πrh+2πr^2
A=2π(0.4175)(0.077)+2π(0.4175^2)
A = 3.12
Nickel = 5 Cents
$2 = 200 Cents
200 / 5 = 40
(3.12)(40) = 124.8 In
Answer:
The answer is 0.8 in^2
Step-by-step explanation:
Data
diameter = 0.835 in
thickness = 0.077in
Roll of $ 2.00
Procedure
1.- Find the total number of nickels
# of nickels = 2/ 0.05
# of nickels = 40
2.- Calculate the Circumference
C = 2*pi*r
r = 0.077/2
r = 0.0385
C = 2*3.14*0.0385
C = 0.242 in
3.- Calculate the area of the thickness
Area = 0.242* 0.077*40
Area = 0.745 in^2
4.- Calculate the area of the base and the top
Area = 2*pi*r^2
Area = 2*3.14*(0.0382)^2
Area = 0.0093 in^2
5.- Calculate the total area of the roll
Total area = Area of the thickness + Area of the base and top
Total area = 0.745 + 0.0093
Total area = 0.7543 in^2 This is the result
Rounding to the nearest tenth = 0.8 in^2

Show that the credit card number

Explain how you know.
Answers
Step 1b. For a card with an odd number of digits (e.g., American Express), double alternating digits starting with the second digit in the sequence.
Step 2. If the doubling resulted in a number with two digits, add them together to get a single digit number
Step 3. Now go back to the original credit number and replace the digits that you doubled with the new value — either the doubled value, or the doubled value with the digits added together — and add it all up.
Step 4. Check to see if the sum is evenly divisible by 10 (you can simply look to see whether or not it ends with a zero).
If the card number does not pass this check, then it is not a valid number. If, on the other hand, it does pass, then it may be a valid number with valid credit report.

(Inequalities) what do you have to do when multiplying or dividing by a negative number?
Answers
Answer:
When we multiply or divide by a negative to solve an inequality, it's the same as multiplying or dividing by a negative to solve a regular equation! Just remember to multiply or divide both sides by the same quantity, then simplify! Remember, when multiplying or dividing by a negative YOU MUST FLIP THE INEQUALITY SIGN.
Step-by-step explanation:
You are welcome.
And I hope this helps. :)
Answer:
Step-by-step explanation:
If you begin with an inequality and wish to solve for one of the variables, you must isolate that variable on the right side of a new inequality. Now supposing that that variable is negative in the given inequality, and that you must change that sign to positive. Generally you can either multiply every term in the given inequality by -1 or divide every term by -1. In both cases you must change the direction of the inequality sign.
Example: Given -3x > 2 + 5y, solve for x. To do this, multiply all three terms in the inequality by (-1/3), which yields x on the left and -2/3 - (5/3)y on the right. We must reverse the direction of the inequality sign, so the final answer is x < -2/3 - (5/3)y.

Answers
Answer:

Step-by-step explanation:
Hey There!
So the rule about interior angles of a trapezoid
is that the angles that lie on the segments that are not parallel are supplements
so essentially what I'm saying is that angle R and angle U are supplementary angles so to find x we do
180=15x+8+7x-4
step 1 combine like terms
15+7=22
8-4=4
now we have
180=22x+4
step 2 subtract 4 from each side
180-4=176
now we have
176=22x
step 3 divide each side by 22
176/22=8
so x=8
now we plug in 8 to 15x+8
8x15=120
120+8=128
so we can conclude that angle R = 128
