Answer:

Step-by-step explanation:
Given
Age 11 Age 12 Total
Girls 3 5 8
Boys 1 3 4
Required

The number of aged 12 children is:


The total number of children is:

So, we have:


Simplify

First cut the shape into a square, triangle and rectangle. Then add all 3 areas. Area of a quadrilateral is A= b x h So once square is 4 X 4= 16. The rectangle has a area of 4 x 2= 8. The triangle, using the formula 1/2bh has an area of 1/2 x 2 x 4 = 4. So the area of the shape is 16 + 8 + 4 = 28 units
Prime= 19, 37, and 47
Composite= 9, 15, 26, 33, and 45
Hope this helps!
The answer is C, 135. To find the solution, first find the area of the closet by multiplying 3 by 5, which is 15. Then, find the area of the entire room by multiplying 15 by 10 to get 150. Finally, subtract 15 from 150 to find the solution of 135 square feet.

Answer:
The null hypothesis is rejected this means that 
The 95% confidence interval is
Step-by-step explanation:
From the question we are told that
The standard deviation is s= 0.0001
The sample size is n = 25
The sample mean is 
The population mean is 
The null hypothesis is 
The alternative hypothesis is 
The test statistics is mathematically represented as


So the p-value from the z-table is mathematically represented as


seeing that
we reject the null hypothesis
The critical value of
obtained from the normal distribution table is

The margin of error is mathematically represented as

=> 
=> 
The 95% confidence level is mathematically represented as

=> 
=>
