Answer:

Step-by-step explanation:

Let the number of small boxes = x

and the number of large boxes = y

Total number of boxes = 24

Therefore, equation will be,

x + y = 24 ------ (1)

Since, volume of the smaller boxes = 9 cubic feet

And the volume of larger boxes = 24 cubic feet

Therefore, total volume of the boxes = (9x + 24y)

Since combined volume of all boxes = 441 cubic feet

Therefore, equation will be,

9x + 24y = 441 ------ (2)

Answer:

So, the interquartile range is IQR=22.5.

Step-by-step explanation:

Let us write the numbers in ascending order:

34, 37, 38, 40, 44, | 46, 50, 51, 55, 56, |

57, 61, 62, 65, 65, | 68, 68, 72, 73, 76.

We calculate quartile 1:

$Q_1=\frac{44+46}{2}=45$

We calculate quartile 2:

$Q_2=\frac{56+57}{2}=56.5\\$

We calculate quartile 3:

$Q_3=\frac{65+68}{2}=67.5\\$

We calculate the interquartile range:

$IQR=Q_3-Q_1\\\\IQR=67.5-45\\\\IQR=22.5$

You are stuck at home watching people walk down the street. Assuming half the people are wearing black shoes, 1/3 are wearing wh

svet-max [94.6K]

Answer:

The probability of seeing a person wearing black shoes before seeing a person wearing white ones = 60%

Step-by-step explanation:

People watched walking down the street = 100%

People wearing black shoes = 1/2 = 50%

People wearing white shoes = 1/3 = 33.33%

People wearing red shoes = 1/6 = 16.67%

Probability of black shoes to white shoes = percentage of persons wearing black shoes/sum of the percentages of people wearing black and white shoes)

= 50% : 33.33%

= 60% (50%/83.33%)

When expressed in ratio terms, it means that you will see 1.5 (50%/33.33% or 1.5 : 1) persons wearing black shoes before you see a person wearing white shoes.
