For #11 you add 54 + 59+ 57+ 54. Then you have 224. Then divide 224 by 4 since there are 4 numbers. Your answer should be 56 inches as the average, or mean.
Remember, when you divide, you divide by the number of all the numbers. I'm trying to make sense but hope this helps!

Answer:

Cesar will be doing 15 research reports during the school year.

Step-by-step explanation:

Given:

Number of research report completed = 3

Percentage of the report completed for school year = 20%

We need to find total number of research report completed during school year.

Solution:

Let the total number of research report completed during school year be 'x'.

Now we can say that;

Number of research report completed is equal to Percentage of the report completed for school year multiplied by total number of research report completed during school year and then divided by 100.

framing in equation form we get;

$3=\frac{20}{100}\times x\\\\3=0.2x$

Dividing both side by 0.2 we get;

$\frac{3}{0.2}=\frac{0.2x}{0.2}\\\\x=15$

Hence Cesar will be doing 15 research reports during the school year.

if 368 teenagers in a population of 4,310 report that they have smoked at least one cigarette during the past year, to one decim

allochka39001 [22]

Divide the amount of teenagers that smoked by the total population:

$368 \div 4310 = 0.0853$

Multiply this decimal by 100 to convert into a percentage:

$0.0853 \times 100 = 8.53$

To round to the nearest decimal place, look at the hundredths value:

8.53
3 > 5
8.53 -> 8.5

8.5% of teenagers reported that they smoked at least one cigarette.
