Median: 29
Range: 25
IQR: 14.5

Explanations:

**Median:**
(To find the median, we need to first order all the elements)

Ordered —> 15, 18, 18, 20, 23, 28, 30, 33, 33, 34, 38, 40

(Since there are an even number of elements, we need to add the two elements in the middle and divide by 2)

Median = (28 + 30)/2 = 58/2 = 29

**Range:**

(To find the range, you just have the subtract the smallest one from the largest)

Range = 40 - 15 = 25

**IQR:**

First half of elements —> 15, 18, 18, 20, 23, 28
Second half of elements —> 30, 33, 33, 34, 38, 40

Q1 (Quartile 1) = Median of first half = (18 + 20)/2 = 38/2 = 19
Q3 (Quartile 3) = Median of second half = (33 + 34)/2 = 67/2 = 33.5

IQR = Q3 - Q1 = 33.5 - 19 = 14.5

Answer:

C

Step-by-step explanation:

On the horizontal axis, as the discount (%) increases by 1(%), on the vertical axis; the sales increase (%) increases by 3(%).

When the discount is 10%, the sales increase is 32%.

When the discount is 20%, the sales increase is 62%.

20 - 10 = 10

10 × 3 = 30

32 + 30 = 62 (correct)

Jenise throws a ball 75 times and hits the target 41 times. What is the experimental probability that she will hit the target? S
Nutka1998 [239]

Answer:

Step-by-step explanation:

Probability is the ratio of the required outcome to the total possible outcome

Total outcome = 75

Number of times target was hit (expected outcome) = 41

Pr(she will hit target)= 41/75

Next is to state in percent and u do that by multiplying the resulting fraction by 100

41/75 i n percent.

41/75×100

= 4100/75

= 54.67%

Hence the answer in percentage is 54.67%
