1 3 Sophia took home of the pizza that was left over from a party. The amount she took represents of a 8 whole pizza. 3 1 The equation p = can be used to find the number of pizzas p left over from the party. 8 2 How many pizzas were left over? There were pizzas were left over from the party.
Answer:
Sophia took home 2/5 of the pizza that was left over from a party. The amount she took represents 1/2 of a whole pizza. The equation 2/5p=1/2 can be used to find the number of pizzas p left over from the party.

In a triangle shown, which shows the correct order of the side lengths from smallest to largest.
A= 65 degrees B= 80 degrees C= 35 degrees
Answer:
Not sure if there are options, but the order of side lengths from smallest to largest is j, k, l
Step-by-step explanation:
This is a bad explanation (sorry):
Side length order will be the same order of angle orders. By that, I mean the since angle C has the smallest angle, the side length across from it will also be the smallest. Since angle B is the biggest angle, side L will be the biggest length. This leaves angle A (and side k) in the middle.

Calculate the sample mean and sample variance for the following frequency distribution of heart rates for a sample of American adults. If necessary, round to one more decimal place than the largest number of decimal places given in the data. Heart Rates in Beats per Minute Class Frequency 51 - 58 6 59 - 66 3 67 - 74 11 75 - 82 13 83 - 90 4
Answer:
[tex]Mean = 68.9[/tex]
[tex]s^2 =18.1[/tex] --- Variance
Step-by-step explanation:
Given
[tex]\begin{array}{cccccc}{Class} & {51-58} & {59-66} & {67-74} & {75-82} & {83-90} \ \\ {Frequency} & {6} & {3} & {11} & {13} & {4} \ \end{array}[/tex]
Solving (a): Calculate the mean.
The given data is a grouped data. So, first we calculate the class midpoint (x)
For 51 - 58.
[tex]x = \frac{1}{2}(51+58) = \frac{1}{2}(109) = 54.5[/tex]
For 59 - 66
[tex]x = \frac{1}{2}(59+66) = \frac{1}{2}(125) = 62.5[/tex]
For 67 - 74
[tex]x = \frac{1}{2}(67+74) = \frac{1}{2}(141) = 70.5[/tex]
For 75 - 82
[tex]x = \frac{1}{2}(75+82) = \frac{1}{2}(157) = 78.5[/tex]
For 83 - 90
[tex]x = \frac{1}{2}(83+90) = \frac{1}{2}(173) = 86.5[/tex]
So, the table becomes:
[tex]\begin{array}{cccccc}{x} & {54.5} & {62.5} & {70.5} & {78.5} & {86.5} \ \\ {Frequency} & {6} & {3} & {11} & {13} & {4} \ \end{array}[/tex]
The mean is then calculated as:
[tex]Mean = \frac{\sum fx}{\sum f}[/tex]
[tex]Mean = \frac{54.5*4+62.5*3+70.5*11+78.5*13+86.5*4}{6+3+11+13+4}[/tex]
[tex]Mean = \frac{2547.5}{37}[/tex]
[tex]Mean = 68.9[/tex] -- approximated
Solving (b): The sample variance:
This is calculated as:
[tex]s^2 =\frac{\sum (x - \overline x)^2}{\sum f - 1}[/tex]
So, we have:
[tex]s^2 =\frac{(54.5-68.9)^2+(62.5-68.9)^2+(70.5-68.9)^2+(78.5-68.9)^2+(86.5-68.9)^2}{37 - 1}[/tex]
[tex]s^2 =\frac{652.8}{36}[/tex]
[tex]s^2 =18.1[/tex] -- approximated

George sold 18, 22, 26, 12, 25, 20, and 19 cars per month over the past seven months. He followed the steps below to determine the number of cars he needs to sell in the next month to have a mean number of sales per month of 24.
Step 1: Find the total cars needed to have a mean of 24: 24 times 7 = 168.
Step 2: Find the total cars sold: 18 + 22 + 26 + 12 + 25 + 20 + 19 = 142.
Step 3: Subtract the total cars sold from the total cars needed: 168 minus 142 = 26.
Step 4: State the answer: George needs to sell 26 cars next month.

if f(x-3)=7x+4 for all values of X what is the value of f(-7)
Answer:
-66
Step-by-step explanation:
We have the expression f(x-3) = 7x + 4, in which for x the value is -7.
To solve first substitute x next to f(x).
f((-7) - 3) = 7x + 4
(-7) - 3
f(-10) = 7x + 4
Now that we know x is equal to -10, you may substitute to the actual equation.
f(-10) = 7(-10) + 4
f(-10) = -70 + 4
f(-10) = -66
9514 1404 393
Answer:
-24
Step-by-step explanation:
We want to evaluate the function when ...
x -3 = -7
x = -4 . . . . . add 3
Then, ...
f(-7) = f(-4-3) = 7(-4) +4
f(-7) = -24
__
Alternatively, we can rewrite the function to be f(x).
f(x) = f((x+3) -3) = 7(x +3) +4
f(x) = 7x +25
Now, f(-7) is ...
f(-7) = 7(-7) +25 = -49 +25
f(-7) = -24

Answer:
A, (13/3 x 5/13)
Step-by-step explanation:
So first, you should change the mixed numbers into improper fractions. To convert, just multiply the whole number by the denominator and add the numerator. Do that to both fractions and you should get 13/3 ÷ 13/5. Since you need to switch to multiplication, switch the sign and flip that fraction/ That asnwer is 13/3 x 5/13. Hope that helps! :)

The manager of an apartment complex ordered the air conditioners in the apartments to be replaced. The list shows how many years each air conditioner had been in service
11.8, 11.9, 11.9, 12.2, 12.3, 12.9, 13.3, 13.4, 13.6 13.7
What is the median number of years that an air conditioner had been in service?
Answer:
12.6 years
Step-by-step explanation:
Once you have these written out you kinda just have to look for the middle one and in this that is 12.3 and 12.9 so you add them and then divide by 2. When you add them you get 25.2 and when you divide by 2 you get 12.6. So the median of this data set is 12.6.

A square garden has a diagonal length of 18 feet. What is the area of the garden?
Area=
square feet
Answer:
162 square feet
Step-by-step explanation:
Let the side lengths of the square be l feet each.
Then the diagonal together with any two sides forms an isosceles right triangle.
We can apply the Pythagoras Theorem, which says that, the sum of the squares of the two shorter legs equals the square of the hypotenuse ( the diagonal) in this case.
Divide both sides by
The area of the square garden is 162 ft²
The number of 1 foot by 1 foot square planter boxes that can fill this garden is
The area of the square garden will be 162 square feet.
The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any body is called the surface area.
The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the square in a two-dimensional plane is called the area of the square.
Given that the length of the diagonal of the square is 18 feet. The area of the square will be calculated as,
Area = 1 / 2 x d₁ x d₂
Area = 1 / 2 x 18 x 18
Area = 9 x 18
Area = 162 square feet
