Answer:

x+y = 112 ........ (1)

x-y = 62............ (2)

from (1) and (2)

2x = 174

x = 174/2

x = 87

sub x = 87 in (1)

x+y = 112

87+y = 112

y = 112 - 87

y = 25

so the numbers are 87 and 25

Suppose a miniature golf player sinks a hole-in-one about 12% of the time on any given hole and is going to play 8 games at 18 h

vladimir2022 [97]

A) The probability the golfer got zero or one hole-in-one during a single game is between 10.01% and 11.38%.

B) The probability the golfer got exactly two holes-in-one during a single game is 8.57%.

C) The probability the golfer got six holes-in-one during a single game is close to 0%.

<h2 /><h2>How to determine probabilities</h2>

Since a miniature golf player sinks a hole-in-one about 12% of the time on any given hole and is going to play 8 games at 18 holes each, to determine A) what is the probability the golfer got zero or one hole -in-one during a single game, B) what is the probability the golfer got exactly two holes-in-one during a single game, and C) what is the probability the golfer got six holes-in-one during a single game , the following calculations must be performed:

1 - 0.12 = 0.88
0.88 ^ 17 = 0.1138
0.88 ^ 18 = 0.1001

Therefore, the probability the golfer got zero or one hole-in-one during a single game is between 10.01% and 11.38%.

0.88 ^ 18 - 0.12 ^ 2 = X
0.0857 = X

Therefore, the probability the golfer got exactly two holes-in-one during a single game is 8.57%.

0.12 ^ 6 x 0.88 ^ 12 = X
0.0000000001 = X

Therefore, the probability the golfer got six holes-in-one during a single game is close to 0%.

Help me please with this I will give brainliest

MAVERICK [17]

Answer:

1. 18

2. 72

3. 90%

Step-by-step explanation:

For number 1

To find percentage you multiply the total number of kids with the percentage.

To do this you have to convert the percent into a decimal by moving the dot 2 times from its original location Ex. 20% = .20 as 20 would look like 20.00 in decimal form.

So .20 x 90 = 18

For number 2

Subtract 18 and 90 to find the remanding kids

For number 3

Divide 72 and 90. Make sure the lower number is being divided.

The answer you will get is .8 so move the decimal back two times because you are converting it to a percentage."

You will then get 80.00 as an answer then from there turn it to a percentage

80%

Hope this helps!
