For a class experiment, hilda places different colored marbles in a bag. she pulls a marble at random from the bag, records its color, and then puts the marble back in the bag. she repeats this process 25 times. the overall results are shown in the table.

result: blue red yellow orange
frequency: 6 4 8 7

what is the relative frequency that hilda pulled a red marble?

enter your answer in the box.

The relative frequency of pulling out a red marble is 0.16

Step-by-step explanation:

We are given the frequency table as follows,

Result                 Frequency

Blue                            6

Red                             4

Yellow                        8

Orange                       7

Then, the relative frequency of pulling out a red marble = = 0.16

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
