Answer:

Variability refers to how spread out a group of data is. The common measures of variability are the range, IQR, variance, and standard deviation. Data sets with similar values are said to have little variability while data sets that have values that are spread out have high variability

You can just google this, here is what popped up when I searched it so I could give an exact answer..... Variability<span> is the extent to which data points in a statistical distribution or data set diverge from the average, or mean, value as well as the extent to which these data points differ from each other. There are four commonly used measures of </span>variability<span>: range, mean, variance and standard deviation.</span>

The perimeter of a rectangular park is 500 feet. The length of the park is 100 feet longer than the width. Find the length of th
lord [1]

Answer:

The length of the park is 175 feet

Step-by-step explanation:

Let us solve the question

∵ The perimeter of a rectangular park is 500 feet

∵ The formula of the perimeter of the rectangle is P = 2(L + W)

∵ L is the length and W is the width

→ Equate the rule of the perimeter by 500

∴ 2(L + W) = 500

→ Divide both sides by 2

∴ L + W = 250 ⇒ (1)

∵ The length of the park is 100 feet longer than the width

→ That means L is W plus 100

∴ L = W + 100 ⇒ (2)

→ Substitute L in (1) by (2)

∵ W + 100 + W = 250

→ Add the like terms

∵ (W + W) + 100 = 250

∴ 2W + 100 = 250

→ Subtract 100 from both sides

∵ 2W + 100 - 100 = 250 - 100

∴ 2W = 150

→ Divide both sides by 2

∴ W = 75

→ Substitute the value of W in (2) to find L

∵ L = 75 + 100 = 175

∴ The length of the park is 175 feet

Can someone answer this question please answer it correctly if it’s corect I will mark you brainliest
umka21 [38]

Answer:

2/9

12.5%, 30% ,45%

Step-by-step explanation:

Possible outcomes

W = wild

S = sandy shores

G = green hills

W6  W7   W10

S6  S7   S10

G6  G7   G10

There are 9 outcomes

2 are over a week without hills  (W10 and S10) and

P(10 days not at hills) = # more than 7 days no hills/total

                                               =2/9

We need all the numbers in the same form, I will change to decimal

1/8 = .125

30% = .30

.45

Smallest to largest

.125 <.30 <.45

1/8 < 30% < .45

Changing to percent form

12.5%, 30% ,45%
