Answer:

10 OR 8

At Brighton Middle School, Mr. Yule asked 50 randomly selected students from each grade level about their favorite subject, and

Ugo [173]

Answer:

Yes, he made a reasonable inference by saying about 25 percent of students choose the science.

Step-by-step explanation:

Given that

Number of students for survey = 50

Number of students who choose science = 12

Now

Percentage of student who choose science = $\frac{12}{50} x 100$

Percentage of student who choose science = $\frac{12*100}{50}$

Percentage of student who choose science = 24 %

Now as Mr. Yule said "about 25" percent of students choose the science it can be treated as reasonable approximation.

Now if the number of students in survey become 200, then we can expect 12 out of every 50 students would choose the science. So, in total 48 students would choose the science.

Now lets calculate the percentage of students who choose science.

Percentage of student who choose science = $\frac{48}{200} x 100$

Percentage of student who choose science = $\frac{48*100}{200}$

Percentage of student who choose science = 24 %

Keeping in mind the rules for significant figures, determine how many milliliters there are in 0.073 gallons. 1 gallon = 4 quart

andreev551 [17]

we are given

there are in 0.073 gallons

we can see that there are two non-zero places after decimals

so, there are two siginificant figures

step-1: Change gallons to quarts

we know that

1 gallon = 4 quarts

so, we can write as

$0.073gallons=0.073*1gallon$

$0.073gallons=0.073*4quarts$

$0.073gallons=0.292quarts$

step-2: Change into liter

$0.073gallons=0.292quarts$

we know that

1 liter = 1.057 quarts

$1 quart=\frac{1}{1.057} litre$

$0.073gallons=0.292*1quarts$

$0.073gallons=0.292*\frac{1}{1.057} litre$

$0.073gallons=0.27625 litre$

step-3: Change into millilitre

we know that

$1L=1000mL$

$0.073gallons=0.27625*1 litre$

$0.073gallons=0.27625*1000 mL$

Since, it is asking for only two significant figures

so, we can also write as

$0.073gallons=0.28*1000 mL$

$0.073gallons=280 mL$ ...................Answer
