12 would be considered a natural number, whole number, and an integer
Hope this helped
Answer:
Step-by-step explanation:
Area = 50 × (40+160)/2 =5000 ft^2
You need one bag.
<span>21.72%
The 68-95-99 rule states that 1 standard deviation from the mean will contain 68% (68.27 more specifically) of all data points. For each sample, we multiply the success rate for </span>.6827*.6827*.6827*.6827 =.2172 or 21.72%
25.
The area is b * h, so
(2x + 7) * 4
which is greater than 100 units, so
(2x + 7) * 4 ≥ (don't look at =; only major) 100
8x + 28 ≥ 100
8x ≥ 100 - 28
8x ≥ 72
x ≥ 9
26.
The perimeter is 2 * (b + h), so
2 * (2x + 7 +4) = 2 * (2x + 11)= 4x + 22
which is greater than 50 units, so
4x + 22 ≥ (don't look at =; only major) 50
4x ≥ 50 - 22
4x ≥ 28
x ≥ 7
