Answer:

mean: 14

median: 15

mode: 6, 15, 18

Step-by-step explanation:

For the mean, you add up all the numbers and divide by the number of numbers there are. There are 7 numbers here, so add and divide by 7.

For the median, you line the numbers up from least to greatest.

6, 6, 15, 15, 18, 18, 20

and find the middle number, which is 15.

For the mode, you have to find the number that repeats the most. For this set of numbers, it's 15, 18, and 6. Hope that helps!

Jerome bought C. $4\frac{7}{8}$ pounds of candy.

Step-by-step explanation:

Step 1:

First, we must convert the mixed fractions into improper fractions. To do that we multiply the whole number with the denominator and add with it the numerator while the denominator remains the same.

To convert this fraction $1\frac{1}{2} = \frac{(1)(2)+1}{2} =\frac{3}{2} .$

To convert this fraction $2\frac{3}{4} = \frac{(2)(4)+3}{4} =\frac{11}{4} .$

So Jerome bought $\frac{3}{2}$ pounds of jelly beans, $\frac{5}{8}$ pounds of gumballs and $\frac{11}{4}$ pounds of chocolate.

Step 2:

We add all the values to determine the total candy bought.

$\frac{3}{2} +\frac{5}{8} + \frac{11}{4} = \frac{(4(3)+1(5)+2(11))}{8} .$

$\frac{(4(3)+1(5)+2(11))}{8} = \frac{39}{8} .$

$\frac{39}{8}$ can also be written as $4\frac{7}{8}$ .

So Jerome bought $4\frac{7}{8}$ pounds of candy which is option C.

sesenic [268]

Answer: 1346cm

Step-by-step explanation:

From the question, we are informed that Reagan has a rectangular bedspread that measures 238 centimeters by 435 centimeters and that he wants to sew a fringe around the edge of the bedspread.

This simply means that we have to find the perimeter of the rectangular bedspread and this will be:

= 2(length + width)

= 2(435 + 238

= 2(673)

= 1346cm

The length of fridge needed by Reegan is 1346cm.
