We'll want to end this one with x ≥ another value.
So, subtract 5 from both sides.
x+5≥10
-5 -5
x≥5
So, x must be greater than or equal to 5.
The plane has searched 12,950 hectares. the ratio between hectares to square miles is: 1 hectare is 2.471 acres
The answer will be Mean = 135 Variance = 62 and Standard Deviation = 8
<h3>What is the standard deviation? </h3>
Standard deviation is defined as the amount of variation or the deviation of the numbers from each other.
Given that :
Proportion (p) = 54%
Sample size (n) = 250
Using Normal approximation :
Mean = np
Mean = 250 * 0.54 = 135
Variance = npq ; q = 1 - p = 1 - 0.54 = 0.46
Variance = (250 * 0.54 * 0.46) = 62.1 = 62
Standard deviation = √variance = √62.1
Standard deviation = 7.8803553 = 8

Answer:
307 to 323 blocks
Step-by-step explanation:
The range of allowable number of blocks for a building set is the minimum numbers of blocks in a set to the maximum number of blocks in set that would not cause the set to be sent back. Since the ideal number 315 pieces and the allowed deviance is 8 blocks less or more, the allowable range is:
315 - 8 ≤ N ≤ 315 +8
307 ≤ N ≤ 323.
The range of allowable number of blocks for a building set is 307 to 323 blocks.
