The probability of the friend completing the new level in her first try is 22.5%

<h3>What is probability?</h3>

This is a concept that is used to talk about the likelihood or the chances of an event occuring.

For the digit 8, the frequency is 7

For the digit 9, the frequency is 11

The total number of frequencies is given as

10 + 9 + 6+ 7 + 8 + 12 + 4 + 6 + 7 + 11 = 80

7 + 11 = 18

Probability = 18/80

= 0.225 x 100

= 22.5%

Hudson bought several cans of tennis balls. Each contained both green and yellow tennis balls. He purchased 10 green tennis ball
svp [43]

Answer:

1

Step-by-step explanation:

We don't know how many cans Hudson bought.

We are told, he bought:

10 green balls

5 yellow balls

Each can has 2 green balls, so there are:

10/2 = 5 cans

How can we distribute 5 yellow balls in 5 cans? Simple!

5/5 = 1

Put 1 yellow ball in each can.

So, each can will have:

2 green + 1 yellow (balls)

So, each can has 1 yellow ball

What is the distance between the two points? (-18, -6) &amp; (-18,-1)
Hitman42 [59]

Answer:

5

Step-by-step explanation:

D² = ( x2 - x1 )² + ( y2 - y1 )²

= [ (-18) - (-18) ]² + [ (-1) - (-6) ]²

= ( -1 + 6 )²

D² = ( 5 )²

hence, D = 5

Translate this problem to an equation and solve. The area of a patio is 72 square feet. The length of the patio is 1 foot longer
Inessa05 [86]
A = LW
A = 72
L = W + 1

72 = W(W + 1)
72 = W^2 + W
W^2 + W - 72 = 0
(W + 9)(W - 8) = 0

W + 9 = 0
W = -9......extraneous solution...does not work here

W - 8 = 0
W = 8 <==

L = W + 1
L = 8 + 1
L = 9

so the width (W) is 8 ft and the Length is 9 ft

Crank

Answer:measurement of angle B is

70 \:  \: degrees

<h3>Answer C is correct</h3>

Step-by-step explanation:

6x - 2 + 5x + 18 + 2x + 8 = 180 \\ 13x + 24 = 180 \\ 13x = 180 - 24 \\ 13x = 156 \\  \frac{13x}{13}  =  \frac{156}{13}  \\ x = 12 \:  \: degrees
