Answer: B
Step-by-step explanation:
if its 12y-2 then it would be the same as subtracting 2 from 12+y
Answer:
The correct statement is
The null hypothesis is 
The alternative hypothesis is 
Step-by-step explanation:
From the question we are told that
The population proportion is p = 0.18
The sample size is n = 1240 airplane
The number of airplane is k = 310
Generally the sample proportion is

=> 
=> 
The null hypothesis is 
The alternative hypothesis is 
It is no. You need to figure out the missing angles. You can take 97 and 35 from the yellow triangle and add them up to equal 132. Take 180 and subtract 132 to find the missing angle, which would be 48. The angle 48 compares to the 47 in the green triangle. Since they are not the same, they are not similar.
Answer: 33.13 in
Step-by-step explanation:
First, let's start with the perimeter of the semicircles.
Since there are two, it is easier to do because the perimeter of the two halves will add to one full circle; so we can just calculate without having to halve anything.
The formula for the perimeter (aka circumference) of a circle is 2πr
Plug the radius into the equation to get 2π4, or 8π
8π ≈ 25.13
The perimeter of the rectangle is 6(4) = 24.
We now have to subtract the diameters of the circles, as they are not on the outside of the figure and won't be counted in the total perimeter. From the 24, we subtract the two diameters, or 16 in.
24 - 16 = 8
The total perimeter then comes out to be 25.13 + 8, or 33.13 in
