3/4 divided by 2--> change to multiplication reciprocating the second number--> 2/1 into 1/2==now you have 3/4 times 1/2=3/8

Question:

The circumference of a clock is 22 inches. What is the radius of the clock?

Answer:

Radius = 3.5 inches

Solution:

Shape of the clock is circle.

Circumference of the circle = 2πr

Circumference of a clock = 22 inches

$\Rightarrow2\pi r=22$

$$\Rightarrow2\times\frac{22}{7}\times r=22$

$$\Rightarrow\frac{44}{7}\times r=22$

$$\Rightarrow r=22\times \frac{7}{44}$

$$\Rightarrow r=\frac{7}{2}$

⇒ r = 3.5 inches

Hence the radius of the clock is 3.5 inches.

What is the mean absolute deviation of the following data set

tatuchka [14]

Answer:

4.32

Step-by-step explanation:

First, we have to find the mean of the data set.

16, 11, 9, 12, 11, 10, 10, 8, 15, 0, 2, 15, 14, 7, 11, 5, 14, 20, 3, 11, 13, 7, 0, 5, 21 all added together equals 250. 250 divided by 25 = 10. So 10 is the mean.

Now we have to find the absolute distances of each number from the mean.

16 - 10 = 6... 11 - 10 = 1... so on, giving us this -->

6, 1, 1, 2, 1, 0, 0, 2, 5, 10, 8, 5, 4, 3, 1, 5, 4, 10, 7, 1, 3, 3, 10, 5, 11

Finally, we have to find the mean of the distances (which is done by adding all the numbers above and dividing the sum by the number of values there are).

108 divided by 25 = 4.32.

So, 4.32 is the mean absolute deviation (MAD) of the following data set.

dezoksy [38]

Answer:

r≈5.36656314

Step-by-step explanation:

Since A=πr(r+ $\sqrt{h^2+r^2}$ ) so we get that 226.08/pi≈72 or 226.08/3.14=72 we then plug it in to get 72=r(r+ $\sqrt{36+r^2}$ ) so we get r≈5.36656314
