Answer:
The score is 
Step-by-step explanation:
From the question we are told that
The population mean is 
The standard deviation is 
From the question we are told that the score follow a normal distribution
i.e 
The proportion of score in the top 10% is mathematically
Where x is the minimum score required to be in the top 10%
Now the 
So
So
So the critical value of 0.10 from the normal distribution table is 
So
Answer:
14%
Step-by-step explanation:
First find the total for all the dresses.
Total = 14 + 37 + 22 + 56 + 33
Total = 162
Now you are concerned about the blue dresses.
% = (22 / 162) * 100 = 13.58 %
Rounded to the nearest % it would be 14%
The number of degrees it would occupy in the pie chart would be 360 * 14/100 = 49 degrees.
A mixed number that is equivalent to 16/3 is
5 1/3
The answer is 24.
8 + 8 + 4 + 4 = 24
You can factor this out by thinking of the factors of 56 that have a sum of -1. 7 and 8 are factors of 56 and to get a sum of -1, 8 should be negative. 7 + -8 = -1
So
factored out is (y+7x)(y-8x)
We can check this using FOIL
F = (y)(y) =
O = (y)(-8x) = -8xy
I = (7x)(y) = 7xy
L = (7x)(-8x) =
