The population increases by 500 each year, so multiply the number of years that have passed since 1990 by 500.

1999 - 1990 = 9 years

9 years * 500 = 4,500

Add 4,500 to 22,317 inhabitants.

22,317 + 4,500 = 26,817

Your answer is B) 26,817 inhabitants.

[4] What is the mean for the data set, to the nearest whole number?

Answer = 8

Explanation:

Mean = Add up all data values to get the sum and Count the number of values in your data set. Divide the sum by the count

5 + 8 + 8 +8 + 8 + 9 + 9 + 9 + 10 + 10 = 84/10=8.4

Mrs. Clark wants to plant rose bushes along the front of her house. The length she wants to cover is 13 feet, and she wants to a

larisa86 [58]

Answer:

Mrs Clark spends in total $119 on rose bushes.

Step-by-step explanation:

Here, the total length that needs to be covered = 13 ft

The distance between 2 consecutive rose pant = 2 ft

Cost of planting each bush = $17

Now, if we plant first plant at 1 feet,

Then the second bush will be planted at a distance of 2 ft + 1 ft = 3 ft

Third bush = Second Bush + 2 ft = 3 ft + 2 ft = At 5 ft

Fourth bush = Third Bush + 2 ft = 5 ft + 2 ft = At 7 ft

Fifth bush = Fourth Bush + 2 ft = 7 ft + 2 ft = At 9 ft

Sixth bush = Fifth Bush + 2 ft = 9 ft + 2 ft = At 11 ft

And, lastly Seventh bush = Sixth Bush + 2 ft = 11 ft + 2 ft = At 13 ft

So, as to cover a total of 13 ft, 7 bushes are planted in total which are 2 ft apart from one another.

Now, cost of planing 7 rose bushes = 7 x ( Cost of planting 1 rose bush)

= 7 x ($17) = $119

Hence, Mrs Clark spends in total $119 on rose bushes.

Find the interquartile range of the following data set.

BigorU [14]

The interquartile range of 48, 26, 31, 50, 38, 40, 42, 34, 44, 36, is: D. 10.

<h3>What is the Interquartile Range of a Data Distribution?</h3>

The interquartile range of a data distribution is determined as: upper quartile (Q3) - lower quartile (Q1).

<h3>How to Find the Upper Quartile and Lower Quartile of a Data Distribution?</h3>

The upper quartile of a data distribution is the center of the second half of a data distribution while the lower quartile is the center of the first half of a data distribution.

Given the data, 48, 26, 31, 50, 38, 40, 42, 34, 44, 36:

Order the data set as, 26, 31, 34, 36, 38, 40, 42, 44, 48, 50

The first half of the data is: 26, 31, 34, 36, 38.

The center is 34.

Lower quartile (Q1) = 34.

The second half of the data is: 40, 42, 44, 48, 50. The center is 44.

Upper quartile (Q3) = 44.

Interquartile range = 44 - 34

Interquartile range = 10
