Answer:
a. 47.5%
Step-by-step explanation:
1. Find the z-score for 405: 405-455/25 = -2
2. Find the z-score for 455: 455-455/25 = 0
3. Using technology or a chart, find the percentage that corresponds with the z-scores: -2 = 0.0228 or 2.28%, AND 0 = 0.5000 or 50%
4. Find the difference between the percentages by subtracting them: 50% - 2.28% = 47.72%
5. Most of the time, the answers aren't exact, so since 47.72% is closest to 47.5%, I would say that's the answer.

Hey there!
32 + 3(6 − 22) ÷ 6
= 32 + 3(-16) ÷ 6
= 32 + (-48)/6
= 32 + (-8)
= 32 - 8
= 24
Therefore, your answer SHOULD BE: 24
Good luck on your assignment and enjoy your day!

Answer:
24
Step-by-step explanation:
You have to solve this according to BODMAS theorem,
That means,
B - brackets
O - of
D - division
M - multiply
A - addition
S - subtract
Let's solve
32 +3 (6-22) ÷ 6
32 + 3 × (-16) ÷ 6
32 - 48 ÷ 6

Step-by-step explanation:
A scientist was in a submarine below sea level studying ocean life over the next 10 minutes she dropped 23.5 feet how many feet has she been below sea level if she was 89.2 feet below sea level after she dropped
Answer:
65.7 ft.
Step-by-step explanation:
at first, let's say she was x fts. below sea level.
over the next 10 minutes she drops 23.5 ft.
that is her height below sea level then becomes
(x + 23.5) ft.
and it's given that she dropped to 89.2 ft. below sea level.
x + 23.5 = 89.2
x = 89.2 - 23.5
x = 65.7 ft.
and x was the height she's been below sea level.
Therefore ,she's been 65.7 ft. below sea level.
Answer:
65.7
Step-by-step explanation:
We need to find out how many feet she was at. So it is really simple you have to subtract 23.5 from 89.2 and you will get 65.7 which was how many feet she was.

Answer:
Equation: P(w) = 4w + 8
Step-by-step explanation:
The step is zero. That and being told that the relationship is linear.
The general equation is P(w) = mw + y intercept.
When w = 0 then P(w) = 8
The only way that can happen is when P(w) = 0 + y intercept
y intercept = 8 because P(w) = 8
So far what we have is P(W) = mx + 8 So you are starting with 8 rats.
Now suppose w = 2. The number of rats P(2) that you get is 16
So you are solving for m.
16 = m*2 + 8 Subtract 8 from both sides
16 - 8 = 2*m + 8 - 8 Combine
8 = 2m Divide by 2
8/2 = 2m/2
m = 4

Convert numbers 359 to binary
Expand 359 as a sum of the largest powers of 2 that you can:
359 = 256 + 103
359 = 256 + 64 + 39
359 = 256 + 64 + 32 + 7
359 = 256 + 64 + 32 + 4 + 3
359 = 256 + 64 + 32 + 4 + 2 + 1
359 = 2⁸ + 2⁶ + 2⁵ + 2² + 2¹ + 2⁰
359 = 1 0110 0111₂
Help please don’t know what to do???!
Answer:
81.75
Step-by-step explanation:
First, find the median of all the answers.
78.25, 77.75, and 84 = 80 (median)
now that we know 80 is the median, we will add it to our solution.
And still, there is no OTHER TEST in to make this stay 80.
78.25, 77.75, 84, and 80 = 79.125
since this is incorrect, we go higher.
78.25, 77.75, 84 and 81 = 79.625
since this is also incorrect, we go higher.
78.25, 77.75, 84 and 82 = 80.125
since this is higher and incorrect, we will go lower to 81.5.
78.25, 77.75, 84 and 81.5 = 79.875
since this is lower AND 82 is not the correct solution, we will go up by 0.25.
78.25, 77.75, 84 and 81.75 = 80
To check, we will do the problem again.
78.25, 77.75, 84 and 81.75 = 80
So, the solution is 81.75

Answer:
see attached$33.97$1833.970.584Step-by-step explanation:
1. We cannot be sure of your table headings, so we used ones that seem to fit. The completed table is attached.
The amount of interest is computed first. It is the product of the previous balance and the monthly interest rate: 0.155/12. This amount is rounded to cents, as it would be in real life.
The remainder of the payment after interest is paid goes to reduction of the principal amount owed. That payment to principal is subtracted from the previous EOM Balance to give the new end-of-month balance.
The total of payments to date is found in the Accrued Pmt column.
__
2. For the last payment, we made note of the interest owed and the outstanding balance, and added those values to get the payment amount. The result is the final balance is zero. The last payment is $33.97.
__
3. The total of all payments is $1833.97.
__
4. The "debt ratio" is presumed to mean the ratio of the credit card balance to the credit card limit. That ratio is ...
1753.42/3000 ≈ 0.584 . . . . "debt ratio"
_____
Additional comment
Various definitions of "debt ratio" are used by different folks for different purposes. Sometimes, it means the ratio of debt to income. Sometimes it means the ratio of minimum payments due to income. Here, we're not given any income information, so we presume the ratio is supposed to mean the fraction of credit limit that is being utilized.
