<span>So we wan't to see how long would it take to clean 5 showers if the time it takes to clean one shower is 5.22 mins. Lets say that the complete time that it takes to clean all showers is equal to x. then x would be: x=5*5.22mins. So we get: x=26.1 min. So the time it takes to clean all 5 showers is 26.1 mins. </span>
Answer:
15.87% probability that a randomly selected individual will be between 185 and 190 pounds
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation , the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
What is the probability that a randomly selected individual will be between 185 and 190 pounds?
This probability is the pvalue of Z when X = 190 subtracted by the pvalue of Z when X = 185. So
X = 190
has a pvalue of 0.8944
X = 185
has a pvalue of 0.7357
0.8944 - 0.7357 = 0.1587
15.87% probability that a randomly selected individual will be between 185 and 190 pounds

Answer:
-0.84
Step-by-step explanation:
In decimal, the expression is ...
-1.34 +1.50 -1.00 = -0.84
__
As fractions, the expression is ...
-67/50 +75/50 -50/50 = (-67+75-50)/50 = -42/50 = -21/25
Answer:
The x in this question is 151 degrees
