Answer:
It’s is also 6 and 9
Step-by-step explanation:
It’s 6 and 9 cause you divide
A. 176 because if there are 252 total and 76 on the balcony your answer is 252-76.
Answer:
The answer is A because when you take both X and Y they are both negative so the only way to keep the answer negative would be to add them.
If you subtract one from the other it adds the opposite
If you multiply them the negatives cancel each other and the answer becomes positive
If you divide them the negatives cancel out and so again the answer would be positive
Step-by-step explanation:
When you add an negative number to another negative number your number stays negative

Answer: 2.5%</h3>
=============================================================
Explanation:
Notice how 98-2*6 = 98-12 = 86. So we're 2 standard deviations below the mean.
Start at the center, which is where the highest point is located. The value 98 is at the center. Then move 2 spots to the left, which has us move 2 standard deviations lower than the mean, and we arrive at 86. Refer to the diagram below.
From here, we add up the percentages in that diagram that are below the 86 mark. Those percentages are the 0.15% and 2.35%
So we get (0.15%) + (2.35%) = 2.5% which is the answer
Side note: This diagram is using the Empirical Rule. Some textbooks call it the "68-95-99.7 rule", but that's more clunky of a name in my opinion. The three values 68, 95 and 99.7 refer to the approximate percentage values within 1, 2 and 3 standard deviations of the mean.
<h2>A≈1385.44</h2>
A= π r^2 = π*21^2 ≈ 1385.44236
