Ok, so when you're reading the bar graph, you can tell how many participants are in each group by looking at the y-axis. For example, there are 30 people under 17. There are 35 people aged 18-24, etc. The numbers on the y-axis you add up. So 30 (for under 17)+35(for 18-24), etc. Now, a percentage is basically a proportion. So the whole, which in this case is the total amount of people surveyed, will always be the denominator. Then the portion that we are trying to find, which in this case is the people surveyed under 17, will be the numerator. Hence, 30/140.

The question asks you for the total populations of Cambridge, Massachusetts, and Boston, Massachusetts, altogether. That means you have to add the two given numbers together: 616,535 + 101,355 = 717,890. This, of course, is also what Hana did and got for the answer, therefore her statement is the correct one.

Hope I helped you! :)

Explain how using the formula for simple interest can help you in solving word problems.

He ran for six (6) miles every day. 4 in the morning and 2 at night = 6 per day.

He did this for four (4) days. The way to figure this would be to go 6 * 4. This equals 24 miles.

Go back a few steps (punny!).

So days multiplied by how many miles he ran a day which is calculated by miles in morning added to miles at night.

days*(miles per morning + miles per night)

days=4

miles per morning=4

miles per night = 2

4 * (4+2)

Calculating this out....

4 * (4+2)

(4+2 = 6)

4 * 6 = 24.

So A is the answer.

9 11/12- 2 8/11 is a problem that i need help on

Okay here are the steps you can follow!

9 11/12 ----> improper fraction ----> 119/12

2 8/11 ----> improper fraction ----> 30/11

119/12 - 30/11

(119/12 - 30/11) * 132

11(119) - 12(30)

1309 - 360

__949__What is the answer to this problem 452q=39,324 ?

To do that you would divide 452 on both sides.

You should now have this Q=87

Your answer is 87.

**A. Put a zero after the 4 in 35.4 and align the 7 in 7.01 with the 5 in 35.4.**

The decimals always need to line up. It should look like this on paper:

m represent the weight of the boxes that Marco lifted.

d represent the weight of the boxes that Drew lifted.

The boxes that Drew lifted each weighed 8 lb less than the boxes Marco lifted:

d = m - 8

So the weight of one box that Drew lifted is (m - 8). Since he lifted boxes, the total number of pounds Drew lifted is 14(m - 8)

This means that you have to check if the results meet the original requirements or statements.

Ideally, you should try to solve the same problem by a second method, and/or you should substitute the results into the given relationships given in the problem statement to chek coherence of your results.

**Then the answer is option b.**

μ = $597

σ = $39

X = 646

The z-score is determine using:

z = (X - μ) / σ

z = (646 - 597) / 39

z = 1.2546

I'm not sure about using the Ncdf function but you can refer to the z-score tables to get the probability for z = 1.2456 which is 0.8944 but this refer to the probability that the actual cost will be less than the budgeted amount. To get the probability that the actual cost will be greater than the budgeted amount we subtract the obtained probability from 1,

1 - 0.8944 = 0.1056

So, the probability is 0.1056 or 10.56%, say 11%.

** Problem-solving activity includes**

1.Understanding the problem,that is nature of the problem, then Completely define in your own way.

2. Determining why this problem has accrued,

3. Identifying the ways to solve the problem,

4. Prioritizing the given alternatives that is ways and then arranging the alternatives for a solution,

5. Then applying the best solution or arrangement for the given problem.

There are two ways considered for problem-solving activity

(1). Trial and Error (2) Reduction in steps

**It totally depends on the kind of problem , which you are solving. There may be Less than five alternatives ,equal to five alternatives or more than five alternatives to solve the problem.**

**Option B: False **

The expresssion

**x best represents the width of the rectangle.**

The expression

**x + 12 best reprents the lenght of the rectangle.**

This is because if you call x the width, then the length is 12 more than that, i.e. 12 + x.

If you wanted to solve the problem now you could write

2*(width + length) = perimeter

2(x + 12 + x) = 24 and solve for x.

But

**the answer to the question is:**

**x best represents the width of the rectangle.**

**x + 12 best reprents the lenght of the rectangle**.

If their sum is 141 we can write:

n + (n+1) = n + n + 1 = 2n + 1 = 141

2) now this is bit tricky. First integer is:

2n-1

the reason for this is because 2n is always even number for any n. when we subtract 1 we always get odd number. Next consecutive odd number is:

2n-1 + 2 = 2n+1

when we sum these 2 numbers we get:

2n-1 + (2n+1) = 2n - 1 + 2n + 1 = 4n.

Now the important part. 4n and 2n are both always even numbers so it doesnt matter if we write 2n or 4n or 6n. If you give yourself thought experiment you will see that sum of two consecutive odd integers is always even integer.

which means that we can write our formula in multiple ways and one of them is:

2n + 2.

2n is always even number and if we add 2 again we get even number.

answer is 2n+2
