The answer could be expressed as 2^8 because the product is 16!
A person to the hundred to the store get lost 40% of the selling price of 100
28: 1, 2, 4, 7, 14, 28
40: 1, 2, 4, 5, 8, 10, 20, 40
The common factors are 1, 2, and 4.
You can use a factor rainbow to help you find the factors (:
Answer:
The probability that the diameter falls in the interval from 2499 psi to 2510 psi is 0.00798.
Step-by-step explanation:
Let's define the random variable, "Comprehensive strength of concrete". We have information that is normally distributed with a mean of 2500 psi and a standard deviation of 50 psi (or a variance of 2500 psi). In other words, .
We want to know the probability of the mean of X or that falls in the interval . From inference theory we know that :
Now we can find the probability as follows:
Where , then:
Oh goodness i have no clue
