How many of the customers on plan B text?
13 customers
What is the probability that a randomly selected customer who is on plan B uses the phone most often to text? Give the answer in fraction form.

Step-by-step explanation:
edg 2020
The probability that a randomly selected customer who is on plan B uses the phone most often to text is 13/23
What is the probability?Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
P(E) = Number of favorable outcomes / total number of outcomes
The customers are on payment plan B = 23 customers
The customers on plan B text = 13 customers
The probability that a randomly selected customer who is on plan B uses the phone most often to text
= 13/23

The area of the square base is S(x), where x is the length of the concrete foundation, and the area of the base of the cylindrical tank is C ( r ), r is the radius of the cylindrical tank. What does the expression S ( C ( r ) ) represent?
Answer:
C(r) is the area of the base of a cylindrical tank with radius r.
We know that this area is:
C(r) = pi*r^2
S(x) is the area of the square base where x is the side length of the base.
S(x) = x*x
Now, we have the expression:
S( C(r)) wich means that we are evaluating the function S(x) in the point x = C(r)
Now, we have a problem here.
In S(x), S(x) is in units of area, and x is in units of length.
And the same for C(r), C(r) is in units of area, and r in units of length.
then we can not have x = C(r)
Then this expression does not represent anything, because the units do not match, so it has no physical sense.
Which choice correctly explains which product is the better buy? Coffee Brand A is sold for $6.99 per pound Coffee Brand B is sold for $5.69 for 12 ounces Question 1 options: A Coffee Brand A is a better buy because its unit rate is $2.29 per ounce B Coffee Brand A is a better buy because its unit rate is $0.44 per ounce C Coffee Brand B is a better buy because its unit rate is $2.11 per ounce D Coffee Brand B is a better buy because its unit rate is $0.47 per ounce.
Answer: Choice B
Coffee Brand A is a better buy because its unit rate is $0.44 per ounce
=======================================================
Explanation:
Brand A is sold for $6.99 per pound, which is the same as saying $6.99 per 16 ounces. The unit rate is 6.99/16 = 0.436875 = 0.44 dollars per ounce
Brand B is sold for $5.69 for 12 ounces. The unit rate is 5.69/12 = 0.47416 = 0.47 dollars per ounce
Brand A is cheaper per ounce compared to brand B.
------------------
Here's another way we can look at it
Brand A is $6.99 per 16 ounces. We can set up the equation below
6.99 dollars = 16 ounces
then divide both sides by 16 to turn "16 ounces" into "1 ounce"
So,
6.99 dollars = 16 ounces
6.99/16 dollars = 16/16 ounces
0.436875 dollars = 1 ounce
0.44 dollars = 1 ounce
is the unit rate for brand A.
Similar steps would happen with brand B as well.

20 points Without solving the systems, determine if there is 0, 1 or infinite solutions. Explain how you know.
Answer:
Infinite Solutions.
Step-by-step explanation:
3x+2y=8 for x:
3x+2y=8
3x+2y+−2y=8+−2y(Add -2y to both sides)
3x=−2y+8 3x 3 = −2y+8 3 (Divide both sides by 3)
x= −2 3 y+ 8 3
Substitute −2/3y + 8/3 for x in 4.5x+3y=12:
4.5x+3y=12
4.5( −2/3y+ 8/3 )+3y=12
12=12(Simplify both sides of the equation)
12+−12=12+−12(Add -12 to both sides)
0=0
Infinitely many solutions.
Answer:
Infinite Solutions.
Step-by-step explanation:
3x+2y=8 for x:
3x+2y=8
3x+2y+−2y=8+−2y(Add -2y to both sides)
3x=−2y+8 3x 3 = −2y+8 3 (Divide both sides by 3)
x= −2 3 y+ 8 3
Substitute −2/3y + 8/3 for x in 4.5x+3y=12:
4.5x+3y=12
4.5( −2/3y+ 8/3 )+3y=12
12=12(Simplify both sides of the equation)
12+−12=12+−12(Add -12 to both sides)
0=0
Infinitely many solutions.
