Answer:

12.683%

Step-by-step explanation:

The effective annual rate is given by ...

(1 +r/n)^n -1

where r is the nominal annual rate, and n is the number of compoundings per year. Filling in the given numbers, we have ...

effective rate = (1 +0.12/12)^12 -1 ≈ 0.12683 = 12.683%

The average number of newspapers for sale in an airport stand is 15. SD is 6. The average age of the pilots is 36 and SD is 4. W

balu736 [363]

Answer:

The average age of pilots has a lower coefficient of variation, so it is the most consistent data set.

Step-by-step explanation:

The coefficient of variation is used to measure consistency of a data set. It is the standard deviation divided by the mean. The higher the coefficient of variation, the more variable, that is, the least consistent the data set is.

The average number of newspapers for sale in an airport stand is 15. SD is 6.

The consistency is:

$C = \frac{6}{15} = 0.4$

The average age of the pilots is 36 and SD is 4.

The consistency is:

$C = \frac{4}{36} = 0.11$

The average age of pilots has a lower coefficient of variation, so it is the most consistent data set.

Identify the volume and surface area of the hemisphere in terms of π. HELP ASAP!!

posledela

Answer:

Step-by-step explanation:

Use the formula for the SA of a hemisphere.

$SA=2\pi r^2$

Now we can find the radius of the hemisphere, which is 15.

Then, we can square that and multiply it by 2 to get 450.

Now, let's use the formula for the Volume of a hemisphere.

$V=\frac{2\pi r^3}{3}$

Now we can cube 15 and multiply it by 2 to get 6750.

Then we can divide this number by 3.

2250.

So the answer is D.

Two Dimensional Nets and Surface Area - Quiz - Level

Virty [35]

Answer:

$18\ ft^2$

Step-by-step explanation:

The complete question in the attached figure

we know that

The surface area of a cube is equal to the area of its 6 squares faces

The area of one square face is equal to

$A=b^2$

where

b is the length side of the square

we have

$b=1\ ft$

substitute

$A=(1)^2=1\ ft^2$ ---> area of one square face

Find the surface area of three cubes

Multiply the area of one square face by 6 (one cube has 6 faces) and then multiply the result by 3 (3 cubes)

$SA=3[6(1)]=18\ ft^2$
