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
Which statement matches?
Solution: D
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:
Median: 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
Mean: 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
D is the correct answer
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!

3·π·53≈523.59878 and 5 or more raise the score so the 9 makes the 5 into 6 and drop all of the other numbers
The solution is, The Volume is 523.6, of the sphere has a radius of 5 feet.
What is volume?In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.
here, we have,
Given,
r = 5 ft
pi = 3.14
Formula
the volume of sphere is:
V = 4/3 * 3.14 * r^3
Solution
V = 4/3 * 3.14 * 5^3
V = 4/3 * 3.14 * 125
V ≈ 523.59878
V ≈ 523.6 m^3
as, we get,
V≈523.59878
and 5 or more raise the score so the 9 makes the 5 into 6 and drop all of the other numbers.
Hence, The solution is, The Volume is 523.6, of the sphere has a radius of 5 feet.

Answers
Answer:
Ok so basically, the formula for Volume of a Trapezoidal Prism. If the prism length is L,trapezoid base width B, trapezoid top width A, and trapezoid height H, then the volume of the prism is given by the four-variable formula: V(L, B, A, H) = LH(A + B)/2. In other words, multiply together the length, height, and average of A and B.

What is the surface area of the triangular prism below?
Answers
Answer:
Let me figure it out rq hold on
how to find the surface area:
The surface area of the triangular prism is the sum total of the areas of its bases and its lateral faces,
We have 2 triangles to add and 3 rectangles.
Area of a rectangle is length x width.
Area of a triangle is 1/2 x base x height.
The top 2 rectangular sides are 20 x 10 = 200 each = 400 total.
The bottom rectangle is 20 x 12 = 240
The triangles are each 1/2 x 12 x 8 = 48, and there are 2 triangles, = 96
Add them all up: 400 + 240 + 96 = 736 square feet

PLZ, QUICKLY IT IS HOMEWORK Two trains leave the same station at the same time, but are headed in opposite directions. One train travels at 70 mph and the other train travels at 80 mph. How long after they leave the station will they be 50 km apart?
Answers
Answer:
20 minutes( 0.3333 hours) after they leave the station will they be 50 km apart, if the Two trains on opposite tracks leave the same station at the same time. One train travels at an average speed of 80 km/hr and the other travels at an average speed of 70 km/hr.
Step-by-step explanation:
The given is,
One train travels at an average speed of 80 km/hr
The other travels at an average speed of 70 km/hr
Step:1
Formula to calculate the distance traveled by two trains,
Distance traveled by two trains = (Rate of speed of train one +
Rate of speed of other train) × Time
From the given the above equation becomes,
Let, h = Time taken to each the distance
50 = ( 80 + 70 ) h
50 = (150) h
= 0.3333 hours
= ( 0.333 × 60 ) ( ∵ 1 hr = 60 minutes )
h = 20 minutes
Step:2
Check for solution,
From equation (1),
50 = ( 80+70 ) (0.3333)
50 = (150)(0.3333)
50 = 50
Result:
20 minutes( 0.3333 hours) after they leave the station will they be 50 km apart.

343 ft^2 (Closest to Answer D)
Step-by-step explanation:
The triangle on the left has height 24 ft and base 18 ft, and therefore, by the area-of-a-triangle formula A = (1/2)(b)(h), the area of the triangle is
A = (1/2)(24 ft)(18 ft) = 216 ft^2.
The semicircle on the right has radius (18 ft)/2, or 9 ft. Using the area-of-a-semicircle formula A =(pi)(r)^2/2, we find this particular semicircle to have area
A = (pi)(9)^2/2, or approximately 127 ft^2
Adding these two subareas together results in total area
A = (216 ft^2) + (127 ft^2) = 343 ft^2 (Answer D)
