Answer:
Step-by-step explanation:
If it is asking for 1.5 standard deviations above the mean, it is 30 +1.5(6)=39
Answer:
A =576 pi in ^2
Step-by-step explanation:
Circumference is given by
C = 2 * pi *r
48 pi = 2 * pi *r
divide by 2 pi
48 pi /2 pi = 2 * pi * r / 2 pi
24 = r
We can find the area by
A = pi r^2
A = pi (24)^2
A =576 pi in ^2
The top is a triangle with sides 7 and 5.4 Use the Pythagorean theorem to find the 3rd length.
3rd sides = sqt(7^2 + 5^2( = sqrt(49+25) = sqrt(74)
This side is the base of the lower rectangle.
The dotted line is the hypotenuse of a right triangle.
Use the Pythagorean theorem to solve.
sqrt(10^2 + sqrt(74)^2) = sqrt(174)
The dotted line = sqrt(174)
In the smallest of the three triangles (with sides 
) we have
In the second-largest triangle (with sides 
), the length of the missing side is 
. Then in the largest triangle (with sides 
), we have
Equivalently, we have
In turn, we find
Answer: C
