Answer:

See below

Step-by-step explanation:

Think: They want us to make a box-o-gram (histogram and box-whisker-plot combo).

Identify: They gave us the information we need and we know that Alaska is the largest state. We will make the box-o-gram after ordering the data appropriately.

Do: After ordering the numbers from least to greatest, we make calculations for the medians and mean. Here are the answers:

Least: 198

Greatest: 284,332

Q1: 30,123 (Got this by adding the two numbers of the upper half of data and dividing by 2)

Median/mean: 100,233.2 (Average of the data)

Q3: 202,112.3 (Rounded. Got this by adding the two numbers of the middle half of data and dividing by 2)

Answer:

A: 198

B: 30,123

C: 100,233.2

D: 202,112.3

E: 284,332

Yes, this makes sense since the data on the box-o-gram fall within the data given in the chart at the top of the worksheet.

Sliva [168]

Answer:

36 cm

Step-by-step explanation:

The formula to find the area of a triangle is A=1/2bh where b stands for base and h for height.

So, 8 times 9 equals 72, and 72 divided by 2 is 36.

Ling lives 2 miles from school. It took him 15 minutes to bike from school to home. The first half of the distance he biked at a

alexdok [17]

A) time = distance/speed
For the first half of the trip, the time used was
.. (1 mi)/(12 mi/h) = (1/12) h = 5 minutes
Then the last half of the trip took 10 minutes, 1/6 hour.
.. speed = distance/time
.. = (1 mi)/(1/6 h) = 6 mi/h

The speed for the last half of the trip was 6 mph.

b) The average speed was
.. (2 mi)/(1/4 h) = 8 mi/h

Ling's average speed was 8 mph.

You deposit $200 in an account earning 3.5% simple interest how long will it take for the balance of the account to be $221

Rus_ich [418]

It takes 3 years for the balance of account to be $ 221

Solution:

From given information,

Principal = $ 200

Rate of interest = 3.5 %

Amount after "n" years = $ 221

To find: number of years

In simple Interest,

Simple interest = amount earned - principal

Simple interest = 221 - 200 = 21

Thus simple interest earned is $ 21

The formula for simple interest is given as:

$simple\ interest = \frac{ p \times n \times r}{100}$

Where,

p is the principal

n is the number of years

r is the rate of interest per annum

Substituting the given values in formula,

$21 = \frac{200 \times n \times 3.5}{100}\\\\21 = 2n \times 3.5\\\\n = \frac{21}{7}\\\\n = 3$

Thus it takes 3 years for the balance of account to be $ 221
