Mode: value that occurs most
Mean: average (add all values then divide by the amount of number)
Median: middle number

Mode: 80 (appears the most)
Mean: 95 + 80 + 80 + 85 + 80 + 85 + 90 = 595/7 = 85, the mean is 85
Median first put them in order
80, 80, 80, 85, 85, 90, 95
The median is the middle which is 85

Answer: D (Mean is 85)

Explanation:

"The list below shows the quiz scores for a group of students.

95, 80, 80, 85, 80, 85, 90"

The choices talk about median and mode so we find those first:

<u>Median:</u> find by taking which is the middle number when the data is from low to highest

1) rearrange them from low to high

80, 80, 80, 85, 85, 90, 95

2) find middle number

80, 80, 80, 85, 85, 90, 95

The median is 85

<u>Mean:</u> mean is the average of all numbers. Find by adding numbers and dividing by amount of numbers

1) add 80, 80, 80, 85, 85, 90, 95 and get 595

2) There are 7 total numbers so do 595/7 = 85

The mean is 85

<h2><u>D is the correct answer</u></h2>

why?

A is wrong because they are 85 not 80

B is wrong because it is 85 not 80

C is wrong because it is 85 not 80

D is right because it is 85!

2x - 5y = 4<br> 3x - 7y = 5
VMariaS [17]

Answer:

(-3,-2)

Step-by-step explanation:

2x-5y=4

3x-7y=5

solve the equation

x=2+5/2y

3x-7y=5

substitute the value of x into an equation

3(2+5/2y)-7y=5

multiply 3 to 2. and. 3 to 5/2y

6+15/2y-7y=5

minus 6 to 5 and. add 15/2y to -7y

-1/2y=1

divide both sides by -1/2

y= -2

substitute the value of -2 into an equation

x=2+5/2•(-2)

multiply 5/2 to -2

x=2+-5

add but since 5 is negative then subtract the numbers

x= -3

combine y= -2 and x= -3 as a point

So the answer is (-3,-2)

A famous monument is 300 ft tall. When it casts​ 210-ft shadow, a nearby tree casts a shadow that is 27 ft long. About how tall
Nataliya [291]

Answer:

38.57 feets

Step-by-step explanation:

Given that:

Height of monument, h = 300ft

Shadow of monument, s = 210 ft

Shadow of tree, s = 27ft

Height of tree, = x

Using the relation :

Height / shadow = height / shadow

Monument = tree

300 / 210 = h / 27

Cross multiply

300 * 27 = 210 * h

8100 = 210h

h = 8100 / 210

h = 38.57 feets
