Answer: D
Step-by-step explanation:
Tim should expect to pay an extra $52.88 because he forgot to refuel the car. option D is correct.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The car that Tim rented needed 11.75 gallons of gas to refill to the same fuel level as indicated on the Check-Out sheet.
Since the rental agency charges $4.50 per gallon of gas plus a $5.00 refueling charge, the cost of refueling the car will be:
11.75 gallons x $4.50/gallon + $5.00
= $57.88
Therefore, Tim should expect to pay an extra $57.88 because he forgot to refuel the car. The correct answer is (d).

A jury pool has 25 men and 19 women, from which 12 jurors will be selected. Assuming that each person is equally likely to be chosen and that the jury is selected at random, use combinations to find the probability that the jury consists of
Answer:
The number of possible juries is C(30,12) = 30! / (30–12)! * 12! = 86,493,225. The number of possible all-female juries is C(16,12) = 16! / (16–12!) * 12! = 1820. So the probability of an all-female jury is 1820 / 86,493,225 = 0.0021%.

The base of a triangle is 7 inches more than its height. If the area of the triangle is 39 square inches, find the base and height of the triangle
The height of the triangle is
Answer:
the height of the triangle is 6 inches and the base is 7 inches greater, or the base is 13 in
Step-by-step explanation:
The general area-of-a-triangle formula is A = (1/2)(base)(height), or = (1/2)bh.
Here b = h + 7.
Applying the area formula given above: A = 39 in^2 = (1/2)(h + 7)(h), or
78 in^2 = h^2 + 7h,
Rewriting this, in standard quadratic form, we get h^2 + 7h - 78 = 0
-7 ± (49 - 4[1][-78])
Applying the quadratic formula to find h: h = ----------------------------
2
-7 ± (49 + 312) -7 ± 19
or h = ----------------------- = ------------- = {-13, 6}
2 2
Discard the negative 13 root; the height must be a positive quantity.
Thus, the height of the triangle is 6 inches and the base is 7 inches greater, or the base is 13 in
The manager of a children's puppet theatre has determined that the number of adult
tickets he sells for a Saturday afternoon show is a random variable with a mean of 28.3
tickets and a standard deviation of 5.3 tickets. The mean number of children's tickets he
sells is 42.5, with a standard deviation of 8.1.
(a) The adult tickets sell for $10. Let A = the money he collects from adult tickets on a
random Saturday. What are the mean and standard deviation of A?
Applying statistical concepts of multiplication of a variable by a constant, it is found that the mean of A is of $283, while the standard deviation is of $53.
When a constant is multiplied to each data in a variable:
The mean is multiplied by this constant. The standard deviation is multiplied by this constant.In this question, the variable has mean 28.3 and standard deviation of 5.3, and is multiplied by 10, hence:
[tex]28.3(10) = 283[/tex]
[tex]5.3(10) = 53[/tex]
The mean of A is of $283, while the standard deviation is of $53.

36=12d is a proportional or Non-proportional? Explain
Answer:
non-proportional
Step-by-step explanation:
This equation is non-proportional. A proportional equation contains 2 variables where one is proportional to the other. An example would be:
y = 5x
Y is proportional to the value of X at a rate of 5. 5 is the "constant of variation", or the "constant of proportionality"
36 = 12d is not proportional because there is only one variable. That variable can be solved for, giving only one solution.
proportional:
"corresponding in size, degree or intensity"
"having the same or a constant ratio"

Show your work and write an expression using the following criteria:
1. A dividend greater than 1,000
2. The quotient is 58 with a remainder of 22
Answer:
This is correct explanation
Step-by-step explanation:
A dividend is a number we want to divide by another number. It's supposed to be greater than 1000.
Quotient - the integer result of division. Remainder - well, what remains.
9/4 = 2, with remainder 1.
You want to find a number greater than 1000, which, when divided by another number, results in 37, with a remainder of 4.
I would multiply 37 by an increasing number until we get a product greater than 1000. This number is the one you are dividing by. Now add 4 to the product, so that when the sum is divided by the number you found we'll get a remainder of 4.

To find x
Â= 180⁰-8x (angle on a straight line)
B= 180- 9x (angle on a straight line)
:. G + Â + B = 180⁰ ( sum of angles in a triangle)
5x + 180⁰ - 8x + 180⁰ - 9x = 180⁰
5x -8x - 9x + 180⁰ +180⁰ = 180⁰
-12x + 360⁰ = 180⁰
360⁰ - 180⁰ = 12x
180⁰ = 12x ( divide both sides by 12)
x = 15⁰

A = 14°
Step-by-step explanation:
We can use sine law in this situation, where
[tex]\dfrac{\sin A}{a} =\dfrac{\sin B}{b}[/tex]
where a and b are the lengths of the sides opposite the corresponding angles. From the given diagram, we can see that
[tex]\dfrac{\sin A}{7\:\text{yd}} = \dfrac{\sin 75°}{28\:\text{yd}}[/tex]
or
[tex]\sin A = \dfrac{7}{28}\sin 75° = 0.241[/tex]
Solving for the angle A, we get
[tex]A = \sin^{-1}(0.241) = 14°[/tex]

The sum of two numbers is 72 and their difference is 40. Using elimination method
Answer:
here's what we know:
a + b = 72
a - b = 26
We can use the elimination method to solve this problem:
a + b = 72
a - b = 26
---------------
2a = 98
Divide both sides by 2:
a = 49
So we now have:
49 + b = 72
and:
49 - b = 26
Subtract 49 from both sides:
b = 23
and
-b = -23 (multiply both sides by -1) → b = 23
