Answer:
The mean would be 82
Step-by-step explanation:
To find the mean you add up all the numbers.
[tex]68 + 73 + 95 + 81 + 85 + 90 + 77 + 84 + 75 + 92 = 820[/tex]
Then you divide that be the amount of numbers are given to you.
[tex]820 \div 10 = 82[/tex]
And that is how you find the mean.
Sorry if it is wrong I'm tired.

What is 8 x 8 x 8 in exponential form
Answer:
10^3
Step-by-step explanation:
103 is read as “10 to the third power” or “10 cubed.” It means 10 • 10 • 10, or 1,000.
82 is read as “8 to the second power” or “8 squared.” It means 8 • 8, or 64.
54 is read as “5 to the fourth power.” It means 5 • 5 • 5 • 5, or 625.
b5 is read as “ b to the fifth power.” It means b • b • b • b • b. Its value will depend on the value of b.
The exponent applies only to the number that it is next to. So in the expression xy4, only the y is affected by the 4. xy4 means x • y • y • y • y.
If the exponential expression is negative, such as −34, it means –(3 • 3 • 3 • 3) or −81.
If −3 is to be the base, it must be written as (−3)4, which means −3 • −3 • −3 • −3, or 81.
Likewise, (−x)4 = (−x) • (−x) • (−x) • (−x) = x4, while −x4 = –(x • x • x • x).

Question 5(Multiple Choice Worth 4 points)
(05.05)David and Amanda are trying to figure out how long they can live off their $12,350 savings if they spend $240 each month. They have each created an equation.
David’s Equation Amanda’s Equation
y = 12,350 – (240x) y = 12,350 + (240x)
Which person has the correct equation to model this linear relationship?
Amanda’s equation is correct, because their spending will be multiplied by the number of months and then added to their savings.
Amanda’s equation is incorrect, because their spending will increase the amount of their savings.
David’s equation is correct, because their spending will be multiplied by the number of months and then subtracted from their savings.
David’s equation is incorrect, because their spending should be a fixed amount and should not be multiplied.

S. At Food Lion, 28 of every 35 jars of peanut butter on the shelves are creamy peanut butter. What percent of the jars of peanut butter are not creamy?
Answer:
7/35 or 20% of the jars are not creamy
Answer:
20%
Step-by-step explanation:
To find the percent of NOT creamy:
35(total peanut butter) - 28(creamy) = 7
Question now is: 7 is what % of 35?
Formula = a(part) = p(percent)*w(whole)
p = a/w
7/35 = 0.2
0.2 is a decimal so multiply by 100 to get 20%
The answer should be 20% so I hope this helps!

Amrita is 8 years elder to her brother Aman. If the ratio of their ages is 7 : 3, find their present ages?
Answer:
Amrita = 14 years old
Aman = 6 years old
Step-by-step explanation:
Find out the difference of the units.
7 - 3 = 4
Amrita is 4 units/8 years older than Aman.
4 units = 8
1 unit = 8 ÷ 4 = 2
Amrita is 7 units and her brother is 3 units.
Amrita = 7 units x 2 = 14
Aman = 3 units x 2 = 6

At Cindy's birthday each guest will get one-third of a medium sized pizza. There will be 12 people at the party, including Cindy. How many pizza's does her mom need? awnser is 6
Answer: 4 pizzas
Step-by-step explanation:
There are to be 12 people at the party.
Each person is expected to take 1/3 of a pizza.
The total number of pizza needed is therefore:
= No. of people * quantity of pizza
= 12 * 1/3
= 4 pizzas
Note: Answer would be 6 if each guest wanted 1/2 of a pizza.

. When a number is multiplied by 4 before
subtracting from 68, the result obtained is
the same as three times the sum of the number
and 4. Find the number.
Answer:
14
Step-by-step explanation:
if you by multiply 4 by 3 because the sum of three times the sum of the number to get 12
then we multiply 4 by 14 to get 56
then we subtract 68 by 56 to get 12 that is the same number we got from multiplying the 4 and 3 to get 12
so the answer is 14
Giovanni can read 250 words per minute. If there are approximately 400 words on a page, about how many pages can he read in 2 hours? Round your answer to the nearest whole number.
Dude I need help this is due in an hour!!!
Answer:
75
Step-by-step explanation:
He can read = 250w/m
2 hours = 60 x 2 = 120 min
Number of words he can read in 2 hours = 250 x 120 = 30,000
No: of words in each page = 400
No: of pages he reads = 30,000/ 400 = 75

Answer:
Step-by-step explanation:
Since we have points (-1,5) and (3,4) we can find the slope m of y=mx+b
m=(y2-y1)/(x2-d1)=(5-4)/(-1-3)=1/-4=-1/4 so we have
y=-x/4+b, using point (3,4) we can solve for the y intercept, b.
4=-3/4+b, b=19/4, so the line is
y=(-x+19)/4

If OPQ is dilated from point Q by a scale factor of 3, which of the following equations is true about R'S'?
Answer:
segment R prime S prime = three segment RS
Step-by-step explanation:
I took the test,
The true statement is segment R prime S prime = three segment RS
What is dilation?Dilation is a transformation, which is used to resize the object.
The complete question is
If ΔOPQ is dilated from point Q by a scale factor of 3, which of the following equations is true about segment R prime S prime?
Triangle OPQ is shown with point R lying on side OP and point S lying on side OQ Line RS is perpendicular to side OQ.
segment R prime S prime = one half segment RS
segment R prime S prime = two segment RS
segment R prime S prime = segment RS
segment R prime S prime = three segment RS
The scale factor of dilation of ΔOPQ, S.F. = 3
S'Q' = 3 * SQ
also, R'Q' = 3* RQ
By Pythagoras theorem, we have
R'Q'² = R'S'² +S'Q'²
R'S'² = R'Q'² - S'Q'²
R'S'² = (3RQ)² - (3SQ)²
R'S'² = 9(RQ² - SQ²)
R'S' = 3 RS

Amaya went to the pet store. She bought x fish for $3.50 each. She bought fish food for $7.00, and a fish bowl for $12.75. Determine how much Amaya spent at the pet store if she bought 4 fish.
Answer:
$93
Step-by-step explanation:
Amaya went to the pet store. She bought x fish for $3.50 each. She bought fish food for $7.00, and a fish bowl for $12.75. Determine how much Amaya spent at the pet store if she bought 4 fish.
Step 1
We calculate the total amount spent on 1 fish
= Cost of fish + Cost of food + Cost if bowl
= $3.50 + $7.00 + $12.75
= $23.25
Step 2
The total amount spent on 4 fishes is calculated as
= $23.25 × 4 fishes
= $93
At a store, apples cost each and oranges cost each. Harry buys some apples and oranges and spends . He buys a total of pieces of fruit.
Answer:
Number of apples = 6
Number of oranges = 5
Step-by-step explanation:
At a store, apples cost $0.80 each and oranges cost $0.95 each. Harry buys some apples and oranges and spends $9.55. He buys a total of 11 pieces of fruit.
Let
Number of apples = x
Number of oranges = y
x + y = 11 (1)
0.80x + 0.95y = 9.55 (2)
From (1)
x = 11 - y
Substitute into (2)
0.80x + 0.95y = 9.55 (2)
0.80(11 - y) + 0.95y = 9.55
8.8 - 0.80y + 0.95y = 9.55
- 0.80y + 0.95y = 9.55 - 8.8
0.15y = 0.75
y = 0.75/0.15
y = 5
Substitute y = 5 into (1)
x + y = 11 (1)
x + 5 = 11
x = 11 - 5
x = 6
Number of apples = 6
Number of oranges = 5
