Answer:

Height of girls:

Range = 11

IQR = 6

Height of boys:

Range = 12

IQR = 4

Step-by-step explanation:

I placed the height of girls from lowest to greatest (49,49,52,53,53), 54, (57,57,58,58,60) then I subtracted 49 from 60. I subtracted 49 from 60 (60 - 49 = 11) because you subtract the smallest number in the data from the highest number to get the range. Now to find the IQR, you need to find the median. The median is the number right in the middle of the data so in this case it's 54. You can make parenthesis for the all the number behind and in front of the median like I did (You don't have to do it, it makes it easier for me to find the Q1 and Q3). You have to find the Q1 and Q3 which is in the middle of the numbers behind and after 54. For our Q1 it's 52 and for our Q3 it's 58. You can think of the Q1 and Q3 as a median or the middle number for the data. Just in case you need it I placed the Height of the boys here. (52, 54, 57, 58, 58,) 59, (59, 61, 61, 63, 64).

Write and solve an inequality for the following: A fish tank can hold at most 315 gallons of water. if a hose is filling the fis

kvv77 [185]

Rate of flow of water in the fish tank will be given by:
rate=volume/time
the rate of our tank is 15 gallons every 10 minutes. Thus,
rate=15/10=1.5 gallons/ minute
Therefore time taken for the tank to overflow will be:
time=volume×rate
volume of the tank=315 gallons
rate=1.5 gallons per minute
hence:
time=315×1.5
=472.5 minutes
=7 7/8 hours=7.875 hours

VLD [36.1K]

Answer:

$150 + 75h > 600$

Step-by-step explanation:

The inequality that can be used to determine h is shown below:-

As per the given situation, it is mentioned that a plumber could earns $50 for a repair job, so for three jobs he earned $150 as a total amount

Now

We presume h be the number of hours

Also he earns additional $75 per hour worked so $75

Total amount is $150 + $75h)

The total amount is more than $600

So, the inequality equation is as given below:

$150 + 75h > 600$

A nontoxic furniture polish can be made by combining vinegar and olive oil. The amount of oil should be three times the amount o

DENIUS [597]

To answer this question you will use ratios. The information given gives us a part to part ratio of 1 part vinegar for every 3 parts oil.

Because the total amount of furniture polish is 30 ounces, we will need to write one part vinegar to three parts oil as a part to part to whole ratio.

Use this information then and create an equivalent ratio with a total of 30 ounces. See below.

1 vinegar (x7.5) = 7.5 ounces
3 oil. (X7.5). = 22.5 ounces
4 total (x7.5). = 30 ounces

You will need 7.5 ounces of vinegar and a 22.5 ounces of oil.
