The mean(average) is 85.5
The median(middle) is 90
The range(difference between lowest and highest)is 35
The mode is 95, since it popped up 4 times

Answer:

mean = 85.5

median = 90

mode = 95

range = 35

Step-by-step explanation:

First arrange the data in ascending order:

60 75 75 90 90 95 95 95 95

Mean is the average number found by adding all of the numbers together and dividing by the number of terms in the set.

[tex] = \frac{60 + 75 + 75 + 90 + 90 + 95 + 95 + 95 + 95}{9} [/tex]

[tex] = \frac{770}{9} [/tex]

=85.5

Median is the middle number of the set: (9+1) ÷2 = 5th term.

60 75 75 90 90 95 95 95 95

therefore the median is 90

The mode is the number that is repeated more often than any other, so 95 is the mode.

The range = the largest value - the smallest value

= L-S = 95-50

= 35

Therefore the range is 35.

What is the area of a circle with a diameter of 150 cm?

Answers

Answer:

5625π cm²

Step-by-step explanation:

Radius = 150 / 2 = 75 cm

Area = πr² = π(75)² = 5625π cm²

Answer: 17662.5 (I used 3.14 instead of the regular pi but if you need to use pi the answer would be 17671.4587)

Step-by-step explanation:

First, you grab the diameter then divide that by 2 (that gives you the radius of the circle) Then, multiple 75² * 3.14 (or pi) to give you the answer!

Hope this helps! Good luck!

i’m pretty sure it’s 370 bc
1 and a half hours is 80+40 (40 is half of 80)
and 2 and a half hours, so 100 for each hour.
100+100+50= 250

hi there user! Looks like your looking for help, so Mizuki came here to help you!

the answer is:

m is 2/3

The whole work I did:

m + 4 ÷ 3 = 2

m + 4/3 = 2

m + 4/3 - 4/3 = 2 - 4/3

m = 6/3 - 4/3

m = 2/3

Anyways hope this helped! qwq

Answers

Answer:

Step-by-step explanation:

P = 2width + 2length

8x = 2x + 2 length; 8x-2x = 2 length; 6x=2 length

length = 3x

sides= 1/4 of 3x = 3x/4

perimeter of square = 4* side = 4*3x/4 = 3x

x= 4

P rectangle =8x= 8*4= 32

P square = 3x = 3*4 = 12

32-12 = 20 cm greater is the P rectangle than P of square

A rectangle = 2x*x = 2*4*4 = 32

A square =(3x/4)² = (3*4/4)² = 9

32-9 = 23 cm² greater is the A rectangle than A of square

A bag contains 5 yellow balls 3 red balls and 2 green balls. A ball is removed from the bag without looking, the colour recorded, and then returned the bag. A second ball is drawn and its colour is also recorded.

c) What would be the outcome of the 2 balls if it has a probability of 1/10?

Answers

Answer:

the two balls are yellow and green, in either order.

Step-by-step explanation:

P(Y) = 5/10 = 1/2

P(R) = 3/10

P(G) = 2/10

Since the only combination that makes a product of 1/10, so

P(Y)*P(G) = (5//10) * (2/10) = 10/100 = 1/10

So the two balls are yellow and green, in either order.

The balls of two are yellow and green,in either order.

Find the slope and y-intercept of the line in the graph. Express the answers as simplified fractions, if
necessary

The slope is m =
The y-intercept is b =

Answers

Answer:

y-intercept: -3.

Slope:7/5

Step-by-step explanation: Y-intercept: The line crosses the y-axis at y=-3.

Slope: If you start from the point on the y-axis, -3, and count up 7 units, you reach 4 and then count right 5 units to reach a part of the line which touches a point. You go up 7 and go right 5 units. Therefore, the slope is 7/5. You go up, or rise, 7 units, and go right, or run, 5 units.
