Ms. Smith has 132 stickers to give to her students. She has 25 students. If she gives the same number of stickers to each of her students, how many stickers will she have left over? *

Answers

Answer: 7

To find the remaining amount, we must multiply up to 132.

25 x 5 = 125

Subtract 125 from 132.

132 - 125 = 7

Answer = 7

The number of stickers Ms. Smith has leftover is 7.

Ms. Smith has 132 stickers and 25 students. She gives each student the same number of stickers. In order to determine the number of stickers she would have left, the number of stickers each student got has to be determined first. The stickers each student got can be determined by dividing the total number of stickers by the total number of stickers.

Total number of stickers each student got = total number of stickers / total number of students

132 / 25 = 5 (to the nearest whole number).

The total number of stickers distributed.

5 x 25 = 125.

The total amount of stickers left = 132 - 125 = 7 stickers.

mDE = 9

Step-by-step explanation:

mCD and mDE must add up to mCE

Step 1: Set up equation

mCD + mDE = mCE

5x + 1 + 3x + 3 = 20

Step 2: Solve for x

Combine like terms: 8x + 4 = 20Subtract 4 on both sides: 8x = 16Divide both sides by 8: x = 2

Step 3: Find mDE

mDE = 3x + 3

mDE = 3(2) + 3

mDE = 6 + 3

mDE = 9

What is the mean score what is the median of the score brookewood medical center

Answers

Step-by-step explanation:

The mean of a set a score is simply the average score.

  To find the mean, simply sum the individual scores and divide by the total number of scores;

  Mean of a  set of score  = [tex]\frac{Total scores}{Number of scores}[/tex]

Another way to find the mean is using:

   Mean  = [tex]\frac{summation of all f(x)}{summation of all the frequency}[/tex]

Multiply the frequency of each score with the score and divide by the sum of all of the frequency.

2. The median is the middle score;

 Arrange the data set from the lowest to the highest, the median is the one that falls in the middle.

If there are two numbers find their sum and divide by 2.

What is the slope of a line parallel to the line whose equation is 22 - y = 7. Fully
reduce your answer.

Answers

Answer:

The slope of the parallel line is 2

Step-by-step explanation:

Parallel lines have equal slopes, so for this question you need to re-format the equation to match a y=mx+b format (slope-intercept form).

2x -y = 7  |  Subtract 2x from both sides

-y = 7 + 2x  |  Multiply by negative one to make y even

y = 7 + 2x  |  Rearrange the equation to match the formula

y = 2x +7  |  2 is your slope for both parallel lines!
