Answer:

A. 76.2 (mean), 79 (median), 45 (range), 66 and 83 (IQR), 11.42 (standard deviation)

B. 75.5 (mean), 79 (median), 71 (range), 71 and 87 (IQR), 18.94 (standard deviation)

Step-by-step explanation:

- First, rearrange the numbers from descending to increasing order.

- Mean is all numbers added up divided by how many numbers their are.

- Median is center number.

- Range is largest number divided by lowest.

- IQR is when you separate your set of numbers in half and find the center of each half. That is why their is two sets of numbers.

- Standard deviation is a measure of the amount of variation or dispersion of a set of values.

- Hope this helps! If you need more help or a further explanation please let me know; I would be glad to help.

An oxygen tank contained 212 12/3 liters of oxygen before 27 1/3 liters were used. If the tank can hold 240 3/8 liters, how much

lukranit [14]

So, initially 240 $\frac{3}{8}$ -212 $\frac{12}{3}$ were empty:

this is :

$240 \frac{3}{8} - 212 \frac{12}{3} = 240 \frac{3}{8} - 212 +4 = 240 \frac{3}{8} - 216= 24 \frac{3}{8}$

12/4 is 4 so that's why i substituted it with 4.

now, later 27 1/3 were used so we add this tho the original empty space

$24 \frac{3}{8}+ 27 \frac{1}{3}$ = $24 \frac{9}{24}+ 27 \frac{8}{24}$ = $51 \frac{17}{24}$

which is the result!

If a hexagon is worth 5 and a triangle is worth 3, what is a circle

Olegator [25]

Answer:

Step-by-step explanation:

Call pentagon p, circle c and triangle t

We have 2c + 2p = 2p + 2t + c

p = 5, t = 3 so

2c + 2(5) = 2(5) + 2(3) + c

2c + 10 = 10 + 6 + c

2c = 6 + c
