Answer:
use the division to see the the size of he pool it is 6.3
Step-by-step explanation:
Answer:
f(3) = 7
Step-by-step explanation:
f (x)=x + 4
Let x=3
f (3)=3 + 4
f(3) = 7
Answer:
0.0323 = 3.23%. Is unusual
Step-by-step explanation:
Using the normal distribution we can find z value with the mean and standard deviation as follows. x is the value we want to know its probability
z = (x - mean)/standard deviation
z = (5-8.54)/1.91
z = -1.85
Using z tables for normal distribution, for z = 1.85, we have an area under the curve of 0.9677. Since we want to know the probability for 5 minutes or less, we have to substract from
p = 1- 0.9677
p = 0.0323
An event with a probability less than 5% is considered unusual.
23×8= 184
The answer is 184
