There is a 3 out of 20 chance that you can win a game. How many "wins" would you predict if you played the game 50 times?
Answer:
7.5
Step-by-step explanation:
The probability of winning = 3 out of 20 ;
P(winning) = 3/20
Predicted Number of winnings if game is played 50 times ;
P(winning) * number of games played
(3 /20) * 50
0.15 * 50
= 7.5
Predicted Number of winnings = 7.5
Answer:7.5
Step-by-step explanation:
first you want to clarify the numbers which is 3 and 20 and your chance is 3/20 which equals 7.5 but round to the nearest whole number so 8,

A jar contains 8 red counters and 21 blue counters. A counter is taken at random from the jar. what is the probity that it is.
A. red
B. blue
C. green
Since there are no green counters, the probability of selecting a green counter is always 0 in this context.
Given that the jar contains 8 red counters and 21 blue counters, we can determine the probabilities of selecting each color.
Total number of counters in the jar = 8 (red) + 21 (blue) = 29
(a) The probability of selecting a red counter:
Number of red counters / Total number of counters = 8 / 29
(b) The probability of selecting a blue counter:
Number of blue counters / Total number of counters = 21 / 29
(c) The probability of selecting a green counter:
There are no green counters in the jar, so the probability of selecting a green counter is 0.
Therefore, the probabilities are as follows:
A. The probability of selecting a red counter is 8/29.
B. The probability of selecting a blue counter is 21/29.
C. The probability of selecting a green counter is 0.
Please note that since there are no green counters, the probability of selecting a green counter is always 0 in this context.

PLEASE HURRY: On Monday, Florencia's hair was h centimeters long. She got a haircut on Tuesday, so her hair was only 75% of
the length it was on Monday.
Which of the following expressions could represent how many centimeters long Florencia's hair was after the
haircut?
Chose 2 answers:
h(1 - 0.75)
(1 - 75/100)h
3/4h
0.75h
1/4h
Answer:
It seems that you are trying to find the length of hair of Florencia on Tuesday.
Given that length of the hair of Florencia on Monday = h centimeters
On Tuesday, she got hair cut.
So new length of the hair of Florencia on Tuesday = 75% of Monday value
= 75% of (h)
= 0.75* (h)
= 0.75h
Hence final answer is the length of the hair of Florencia on Tuesday is ( 0.75h ) centimeters.
Answer:
3/4h and 0.75h

What is the perimeter of the rectangle whose vertices are at (6, 3), (−6, 3), (−6, −1), and (6, −1)?
Given:
The vertices of a rectangle are (6, 3), (−6, 3), (−6, −1), and (6, −1).
To find:
The perimeter of the rectangle.
Solution:
Distance formula:
[tex]d=\sqrt{(x_2-x_1)^2-(y_2-y_1)^2}[/tex]
Let the vertices of a rectangle are A(6, 3), B(−6, 3), C(−6, −1), and D(6, −1).
Using the distance formula, we get
[tex]AB=\sqrt{(-6-6)^2-(3-3)^2}[/tex]
[tex]AB=\sqrt{(-12)^2-(0)^2}[/tex]
[tex]AB=\sqrt{144}[/tex]
[tex]AB=12[/tex]
Similarly,
[tex]BC=\sqrt{\left(-6-\left(-6\right)\right)^2+\left(-1-3\right)^2}=4[/tex]
[tex]CD=\sqrt{\left(6-\left(-6\right)\right)^2+\left(-1-\left(-1\right)\right)^2}=12[/tex]
[tex]AD\sqrt{\left(6-6\right)^2+\left(-1-3\right)^2}=4[/tex]
Now, the perimeter of the rectangle is:
[tex]Perimeter=AB+BC+CD+AD[/tex]
[tex]Perimeter=12+4+12+4[/tex]
[tex]Perimeter=32[/tex]
Therefore, the perimeter of the rectangle is 32 units.

Answer:
Brooklyn earns four more dollars than Anna does each hour.
Step-by-step explanation:
So basically in order to get the amount ech of them recieve you would have to divide. So for Anna's since her least given number is 10 hours you would divide how much she earns (256) by how many hours she has been working (10) and you get 25.6
Now for Brooke she is given only one piece of evidence so you would use that she has been working for 26 hours and earns 769.6. So divide her earning by the hour and get 29.6
Subtract each of the answers (29.6-25.6) and you would get 4

Answer:
Hope It Help

Answer:
3
Step-by-step explanation:
The unit rate is a rate with 1 in the denominator. The unit rate for this equation would be how much money he makes in one hour. So, to find the unit rate plugin 1 for r and solve for g. One times three (1*3) is equal to 3; therefore, that is the unit rate.
