The maintenance crew of a hotel has to monitor the temperature of the hotel pool and hot tub. To enhance comfort, the management team requests that the mean pool temperature and the mean hot tub temperatures not differ by more than 15 degrees. To estimate the difference in these mean temperatures the maintenance crew selects a random sample of 8 times to check the hot tub temperature and a random sample of 10 times to check the pool temperature. Although the sample sizes are small, the distribution of temperature for the pool and for the hot tub does not show strong skewness or any outliers. The mean pool temperature is 86 degrees with a standard deviation of 3 degrees. The mean hot tub temperature is 101 with a standard deviation of 1.8 degrees. What is the correct 95% confidence interval for the true difference in the population means (hot tub – pool)? Use the conservative df.

3 numbers are in arithmetic progression their sum is15 and their product is 80 determine the 3 numbers
Answers
Answer:
2, 5, 8
Step-by-step explanation:
For starters, let us assume that the numbers are x-d, x, and x+d.
Where d is the common difference between terms.
This mean that we can say, from the question
x-d + x + x+d = 15
3x = 15,
x = 5,
This means that the terms are 5, 5-d and 5+d.
On the other hand,
(5-d) * 5 * (5+d) = 80
(5-d) * (5+d) = 80/5
(5-d) * (5+d) = 16
25 - d² = 16
d² = 9
d = + or - 3.
Finally, the three numbers will be 2, 5, and 8. On the flipside, their sum and product are 15 and 80.

Mara carried water bottles to the field to share with her team at halftime. The water bottles weighed a total of 60x2 + 48x + 24 ounces.
Which factorization could represent the number of water bottles and weight of each water bottle?
6(10x2 + 8x + 2)
12(5x2 + 4x + 2)
6x(10x2 + 8x + 2)
12x(5x2 + 4x + 2)
Answers
Answer: 12(5x2 + 4x + 2) is correct answer
Step-by-step explanation:
60x2 + 48x + 24
if we take 6 as a common factor
6(10x^2+8x+4) so first option is not true
if we take 12 as a common factor
12(5x2 + 4x + 2)
6x & 12x can not be taken as common factor..
so the correct option is 2nd one..
A student has taken three math tests so far this semester. His scores for the first three tests were 65, 67, and 69. Suppose his test scores continue to improve at the same rate. What will be his grade on the sixth (and final) test? What will be his total score for all six tests?
Answers
Answer:
75
Step-by-step explanation:
Scores for his first tests were 65, 67, 69.
Rate of change: +2
y=2x+63; 63 is the 0th test he took, his first test was 65, so 65-2=63. 2x is the rate of change, his tests scores increase by 2 each time.
x=6, 6th test score
y=2(6)+63
y=12+63
y=75
So, on his 6th test he will get a score of 75

Bilbo found a great deal on rings. He bought a ring for 70% of the original price. If he saved $45, what was the original price?
Answers
Answer: $150
Step-by-step explanation:
If Bilbo bought the ring for 70% of the original price, this means that he saved:
= 100% - 70%
= 30%
$45 is therefore 30% of the original price.
Assuming the original price is x:
30% * x = 45
x = 45/30%
x = $150

Kayla is financing $168,125 to purchase a house. She obtained a 25/8 balloon mortgage at 3.85%. What will her balloon payment be
Answers
Answer:
$130,626.56
Step-by-step explanation:
Kayla is financing $168,125 to purchase a house. She obtained a 25/8 balloon mortgage at 3.85%. What will her balloon payment be?
We are told that: She obtained a 25/8 balloon mortgage at 3.85%
This means the loan is amortized for 25 years and she would be monthly payment for 8 years before making the balloon payment.
Step 1
We find Monthly payments
Pmt = (A * i * (1 + i)ⁿ) / ((1 + i)ⁿ - 1)
Where:
Pmt - monthly payment;
A - Loan amount = $168,125
i - periodic interest rate = 3.85% = 0.0385
and
n - number of periods =
1 year = 12 months
8 years = x
x = 8 × 12 months = 96 months
n = 96 months
Pmt = (168,125 × 0.0385 * (1 + 0.0385)⁹⁶) / ((1 + 0.0385)⁹⁶- 1)
Pmt = $873.56
Step 2
When we find the monthly payment, we can compute the balance due after the term of a balloon loan.
B = (A * (1 + i)ⁿᵇ) - Pmt / i * ((1 + i)ⁿᵇ - 1)
Where:
B - Balloon payment
nb - Number of balloon loan periods =
Pmt - Monthly payment = $873.56
B = (168,125 × (1 + 0.0385)⁹⁶) - 873.56 / 0.0385 × ((1 + 0.0385)⁹⁶- 1)
B = $130,626.56
