Nine tanks can hold more than 3
Answer:
Step-by-step explanation:
<u>If Y is between X and Z, then:</u>
<u>Substitute the values and solve for c:</u>
- 11 + 4c = 83
- 4c = 72
- c = 72/4
- c = 18
B. AC and CD are perpendicular because they’re going opposite ways
B. 5.2! If you use a calculator it gives you the direct answer. If you don't have one use paper and illustrate it.
Answer:
We should expect 818 chicks to hatch in 19 to 28 days
Step-by-step explanation:
Normal Probability Distribution
Problems of normal distributions can be solved using the z-score formula.
In a set with mean and standard deviation , the z-score of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Normally distributed with mean of 22 days and standard deviation of approximately 3 days.
This means that
Proportion between 19 and 28 days:
p-value of Z when X = 28 subtracted by the p-value of Z when X = 19.
X = 28
has a p-value of 0.977.
X = 19
has a p-value of 0.159.
0.977 - 0.159 = 0.818
Out of 1000:
0.818*1000 = 818
We should expect 818 chicks to hatch in 19 to 28 days
