In a survey, four out of five people surveyed preferred creamy over chunky peanut butter. 120 people are shopping at the grocery
elixir [45]

Answer: Around 96 people would prefer creamy peanut butter.

Step-by-step explanation:

In the survey was found that 4 out of 5 preferred creamy over chunky peanut butter.

Then the relative frequency is:

4/5 = 0.8 prefer creamy peanut butter.

And we can assume that:

1/5 = 0.2 prefer chunky peanut butter.

We also could multiply these numbers by 100% to obtain the percentage forms:

0.8*100% = 80%

0.2*100% = 20%

Now, if there are 120 people in the grocery store, we can expect that the 80% will prefer creamy peanut butter.

Then we can expect that the number of people that prefers creamy peanut butter is:

N = (80%/100%)*120 = 0.8*120 = 96

Around 96 people would prefer creamy peanut butter.

Karinna's aquarium can hold 80 liters, which is equal to 80,000 cm'. The base measures 100 cm by 40
tresset_1 [31]

Answer:height=20cm

Step-by-step explanation:

Length=100cm

Breadth=40cm

Volume=80 liters which is equal to 80000cm^3

volume=length x breadth x height

80000=100 x 40 x height

80000=4000 x height

Divide both sides by 4000

80000/4000=(4000xheight)/4000

20=height

Height=20cm
