The mean if the scores was misread at 94 but it was 69 is 87.5
How to find the mean of a number?Mean is also known as average. It is mathematically represented as:
Mean = Sum of data/Sample space
Given the following parameters
Mean = 88
Sample size = 50
Substitute
88 = Sum/50
Sum = 88(50)
Sum = 4400
If one of the scores was misread at 94 but it was 69, hence;
Sum + (94-69) = 4400
Sum + 25 = 4400
Sum = 4400 - 25
Sum = 4331
New mean = 4375/50
New mean = 87.5
Hence the mean if the scores was misread at 94 but it was 69 is 87.5

Answer number 1 please thank you
Answer:
$52.5
Step-by-step explanation:
Since 25% is the sale, we subtract 100% (the whole) by the discount, 25%. That leads us to say that we are paying for 75% of the product's price.
We multiply $70 by 0.75 and you get $52.5!

The graph shown is the second derivative
⇒ first derivative equals the area between
- the second derivative function from 0 to 2
- the axis
Thus the first derivative f(2) equals [tex]8 + c[/tex]
c: represents the initial positionHowever there is an inital position for the first derivative ⇒ f(0) = 2.5
Therefore we must add the initial position to the first derivative found
f(2) = 8 + 2.5 = 10.5

Tamora just made the last of her monthly payments on her loan. she had been making these payments for the past nine years. the loan had a principal of $10,675 and an interest rate of 4.75%, compounded monthly. in addition, tamora paid $939.25 in service charges. what was tamora’s total finance charge? round all dollar values to the nearest cent. a. $939.25 b. $11,614.25 c. $3,403.53 d. $2,464.28 please select the best answer from the choices provided a b c d
Tamora’s total finance charge was $3,403.53 if Tamora paid in addition of $939.25 in service charges option (c) is correct.
What is compound interest?It is defined as the interest on the principal value or deposit and the interest which is gained on the principal value in the previous year.
We have:
Principal amount(Loan principal) = $10,675
Interest rate = 4.75 %
Monthly rate = 4.75/12% ⇒0.39583% ⇒ 0.00395
Additional amount she paid in service charge = $939.25
Number of months = 9×12 = 108 months
We can find the total finance charge as follows:
Finance charge = Total amount repaid +service charge - Loan principal
The formula for the monthly payment of the loan is given by:
[tex]\rm Monthly \ payment = \frac{Loan \ principal }{\frac{(1-(1+r)^-^n)}{r} }[/tex]
[tex]\rm Monthly \ payment = \frac{10675}{\frac{(1-(1+0.00395)^-^{108})}{0.00395} }[/tex]
After calculating, we get:
Monthly payment = $121.66
For 108 months, Tamora paid:
= 121.66×108
= $13,139.23
The finance charge will be:
= $13,139.23+$939.25-$10,675
= $3,403.53
Thus, Tamora’s total finance charge was $3,403.53 if Tamora paid in addition of $939.25 in service charges option (c) is correct.

Dumpster #1 contains 45 fewer molded vegetables than dumpster #2. Dumpster #2 contains 80 fewer molded vegetables than dumpster #3. If there are 236 molded vegetables in all the dumpsters combined, how many vegetables are in dumpster #1?
Answer:
22 vegetables
Step-by-step explanation:
Set the #number of molded vegatables in dumpster 1 as X
The number of molded vegetables in 2 is x + 45 and the number of molded vegies in 3 is x + 45 + 80
x + x + 45 + x + 45 + 80 = 236 (combine similar terms)

Find the Circumference.
Answer:
1.
r = 12 m.
d = 24 m.
circumference: 75.36 m² or 24π m²
2.
r = 10 cm.
d = 20 cm.
circumference: 62.8 cm² or 20π cm²
3.
r = 4 dm.
d = 24 dm.
circumference: 25.12 dm² or 8π dm²
Step-by-step explanation:
Circumference of a circle: 2πrπ (pi) = 3.14r (radius) = d/2d (diamater) = 2rSubstitute the the values of the table into the formula:
1.
r = 12 m.
d = 24 m.
circumference: 75.36 m² or 24π m²
2πr
2 * 3.14 * 12
3.14 * 24
75.36 m² or 24π m² <== circumference
12 * 2 = 24 m <== diameter
2.
r = 10 cm.
d = 20 cm.
circumference: 62.8 cm² or 20π cm²
r = 20/2 = 10 cm <== radius
2πr
2 * 3.14 * 10
3.14 * 20
62.8 cm² or 20π cm² <== circumference
3.
r = 4 dm.
d = 24 dm.
circumference: 25.12 dm² or 8π dm²
2πr
2 * 3.14 * 4
3.14 * 8
25.12 dm² or 8π dm² <== circumference
4 * 2 = 8 dm <== diameter

Answer:
The area of a rectangle is given by A = l × w, where l is the length and w is the width.
The length (l) and width (w) of the small rectangle are 14 feet and 6 feet, respectively, so the area of the small rectangle (As) is:
AS = 14 ft. × 6 ft.
= 84 sq. ft.
The length (l) and width (w) of the large rectangle are 20 feet and 7 feet, respectively, so the area of the large rectangle (Al) is:
Al = 20 ft. × 7 ft.
= 140 sq. ft.
