Answer 1

Answer:

164.48 or 164.5

Step-by-step explanation:

So, to make it simpler, you can do the circle like this: 3.14×(8×8). Then you can work down!

3.14 × 64

200.96

and then because it's halved, you divide by 2

100.48

then that's the half circle

The square would just be 8×8=64

then add the circle and the square and viola!

164.48

Answer 2
I don’t really now but I believe it would be 148.46

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.

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.

PLEASE HELP ME WITH BOTH OF THESE PROBLEMS THIS IS DUE SOON PLEASE HELP ME

Answers

Answer:

Step-by-step explanation:

4.

a)

P = 2width + 2length

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

length = 3x

b)

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

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

c)

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

d)

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

b)

total = 17*4 +3  = $71

Sally has two bags of colored cubes. All the cubes are the same size.
One bag contains exactly 4 green cubes and 1 yellow cube.
The other bag contains exactly 3 orange cubes and 3 green cubes. Sally will randomly select 1 cube from each bag. What is the probability she will select a green cube from each bag? ​

Answers

Answer:

I think she is going to take 1 green cube out from “the other bag”... I’m only in 5th grade....

Step-by-step explanation:

1. One Bag = 4 + 1 = 5

2. Other Bag = 3 + 3 = 6

If she takes out 1 from the other bag, they will both contain 5.

6 - 1 = 5

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!
