Answer:
0.1151 = 11.51% probability of completing the project over 20 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.
Expected completion time of the project = 22 days.
Variance of project completion time = 2.77
This means that 
What is the probability of completing the project over 20 days?
This is the p-value of Z when X = 20, so:



has a p-value of 0.1151.
0.1151 = 11.51% probability of completing the project over 20 days.
Answer:
The cubed root of four hundred and forty-eight ∛448 = 7.6517247310896
Step-by-step explanation: Step by step simplification process to get cube roots radical form and derivative:First we will find all factors under the cube root: 448 has the cube factor of 16.Let's check this width ∛16*7=∛448. As you can see the radicals are not in their simplest form.Now extract and take out the cube root ∛16 * ∛7. Cube of ∛16=4 which results into 4∛7All radicals are now simplified. The radicand no longer has any cube factors.
Here is you're answer:
In order to find the answer you have to find the common denominator and then subtract.

- Find the common denominator:



Therefore you're answer is "2/15."

Answer:
Step-by-step explanation:
3.79x.074=.28
3.79+.28=4.07
5(2y+7)
5(2*0+7)
Multiply the bracket by 5
5(2)*5(0)*5(+7)
10*0+35
10*0= 0
0+35= 35
Answer: 35
