Answer:

Mean: 16.

Step-by-step explanation:

—Mean—

13 14 14 16 16 16 16 18 18 19

Simply start by adding the numbers together.

13 + 14 + 14 + 16 + 16 + 16 + 16 + 18 + 18 + 19

= 160.

Then divide it by how many numbers there are. Which is 10.

160 divided by 10 = 16.

—MAD—

Subtract each number by the mean.

|13-16| + |14-16| + |14-16| + |16-16| + |16-16| +|16-16| + |16-16| + |18-16| + |18-16| + |19-16|

Negatives don’t matter, everything should be positive numbers.

3 + 2 + 2 + 0 + 0 + 0 + 0 + 2 + 2 + 3

= 16

16 divided by 16 (amount of numbers).

MAD = 1

–IQR—

Seperate both sides in half.

|13 14 14 16 16| |16 16 18 18 19|

Take the median of each group.

Group 1:

|13 14 (14) 16 16|

This one is 14.

Group 2:

|16 16 (18) 18 19|

This one is 18.

Now take (number from group 2) 18 and subtract by (number from group 1) 14.

18 - 14 = 4

IQR = 4.

Find the probability that a randomly placed point falls within the smaller, inner circle.

worty [1.4K]

Answer:

The probability that a randomly placed point falls within the smaller, inner circle is 25/64

Step-by-step explanation:

The remaining part of question is attached

Solution

The area of smaller circle is

$\pi r^2 = 25 \pi$

The area of large circle is

$\pi r^2 = 64 \pi$

Area of the shaded region

Area of large circle - area of small circle

$64\pi -25\pi = 39\pi$

Probability that the point falls in the region of smaller circle is

$\frac{25\pi }{64\pi } \\\frac{25}{64}$

Please, please, please help me!!!

skad [1K]

For this question, you need to decide whether to use sin cos or tan.
You have the hypotenuse and Ф but you need to find the opposite side.

For those reasons you would use sin, as it has all three in its triangle,
The equation for opposite = sinФ * hypotenuse
So sin49 * 12.38 = 9.3cm.

The answer is 9.3cm.

Hope this helps.
