Answer:

r = 7

Step-by-step explanation:

Given

r + 15  = 4r - 6 ( subtract 4r from both sides )

- 3r + 15 = - 6 ( subtract 15 from both sides )

- 3r = - 21 ( divide both sides by - 3 )

r = 7

Make a box-and-whisker plot for the data. What is the upper quartile value? 42 48 43 65 58 47 60 56 52 64 51 66 56 62
bagirrra123 [75]

In order to draw the Box-whisker plot, we need to rewrite the data in increasing order.


42 43 47 48 51 52 56 56 58 60 62 64 65 66


Mean of the data = (42 + 43 + 47 + 48 + 51 + 52 + 56 + 56 + 58 + 60 + 62 + 64

+ 65 + 66) ÷ 14


Mean of the data = 770 ÷ 14

Mean of the data = 55


Median = (56 + 56) ÷ 2


Median = 112 ÷ 2


Median = 56


Lowest value = 42

Highest value = 66


Range = Highest value - Highest value

Range = 66 - 42

Range = 24


Lower Quartile = 25% of the data

Lower Quartile = 48


Upper Quartile = 75% of the data

Upper Quartile = 63

Pleaseee help I’m so confused
ryzh [129]

Answer:

25

Step-by-step explanation:

(You can do this differently, but I chose to do it like this)

First, convert the 1816 kilograms to pounds.

1816 kilograms = 4003.595 pounds

Then, we can divide 4003.595 pounds by 160 to figure out how many 160-pound people the balcony can hold.

4003.595 ÷ 160 ≈ 25.02

If the balcony holds 26 people, it will collapse, so the answer must be 25.

I hope this helps and please mark me as brainliest!
