A cup contains seven red erasers, four
yellow erasers, nine blue erasers, and five
green erasers. Samantha chose an eraser
at random, did not replace it, and chose
another. What is the probability that both
erasers chosen were blue?
Answer:
17/50
Plzzzz give me Brainliest!
The probability that both erasers chosen were blue is 3/25.
To find the probability that both erasers chosen were blue, we need to determine the favorable outcomes (choosing two blue erasers) and the total possible outcomes.
There are a total of 25 erasers in the cup: 7 red erasers + 4 yellow erasers + 9 blue erasers + 5 green erasers = 25 erasers.
To calculate the probability, we consider the events of choosing a blue eraser without replacement.
For the first pick, there are 9 blue erasers out of 25 total erasers.
After the first blue eraser is chosen, there are 8 blue erasers remaining out of 24 total erasers.
The probability of choosing a blue eraser on the first pick is 9/25.
The probability of choosing a blue eraser on the second pick, without replacement, is 8/24.
To find the probability of both events occurring (both erasers chosen being blue), we multiply the probabilities together:
(9/25) * (8/24) = 72/600 = 6/50 = 3/25
Therefore, the probability that both erasers chosen were blue is 3/25.

shawna got a manicure for $22 she left an 18% tip for the manicurist. what is the total amount that she paid?
pls help ASAP!
Answer:
$25.96
Step-by-step explanation:
So Shawna's manicure was $22 dollars, and she left and 18% tip. In other words, she added 18%, or 0.18 to the total original price. We can represent this with an expression:
[tex]1.18 * 22[/tex]
As she pays 100%, or 1, plus another 18%, or 0.18 to the original price of $22.
Thus her total amount was $25.96
Hope this helps!
Answer:
She paid $25.96 in total
Step-by-step explanation:
The tip was $3.96. When you convert the 18% to a decimal you get .18 then, you multiply the .18 to the $22 (22x .18= 3.96). Finally, you add how much the manicure was to the tip (22+3.96=25.96)

Answer:
i. Girls : 10 merits
ii. Boys : 11.4 merits
iii. The boys did better on average because the number of their mean merits received is higher than that girls.
Step-by-step explanation:
Mean = [tex]\frac{sum of merits}{number of merits}[/tex]
Sum of merits received by boys = 5 + 10 + 19 + 22 + 13 + 10 + 1
= 80
number of merits = 7
Mean number of merits received by boys = [tex]\frac{80}{7}[/tex]
= 11.4286
The mean number of merits received by boys is 11.4
Sum of merits received by girls = 6 + 11 + 15 + 16 + 12 + 10 + 0
= 70
number of merits = 7
Mean number of merits received by girls = [tex]\frac{70}{7}[/tex]
= 10.0
The mean number of merits received by girls is 10.0
Therefore,
i. Girls : 10 merits
ii. Boys : 11.4 merits
iii. The boys did better on average because their mean merits is higher than that girls.

The ratios of red to purple is 2 : 3, ratio of blue to red is 2 : 1, ratio of purple to marbles is 1 : 3 and ratio of marbles to blue is 9 : 4.
What is Ratio?Ratio is a relationship between two quantities which describes how many times one quantity is contained in the other.
The ratio of two numbers p and q can be represented as p : q.
Number of Blue marbles = 8
Number of red marbles = 4
Number of purple marbles = 6
Total number of marbles = 8 + 4 + 6 = 18
The ratio of red to purple = Red marbles : Purple marbles
= 4 : 6
= 2 : 3
The ratio of blue to red = Blue marbles : Red marbles
= 8 : 4
= 2 : 1
The ratio of purple to marbles = Purple marbles : total marbles
= 6 : 18
= 1 : 3
The ratio of marbles to blue = Total marbles : Blue marbles
= 18 : 8
= 9 : 4
Hence the ratios of the given marbles are found.

Hakim received some gift cards for music and movie downloads for his birthday. Using one of them, he downloaded 20 songs and 13 movies, which cost a total of $163. Using another, he purchased 13 songs and 13 movies, which cost a total of $156. How much does each download cost?
Downloads cost $____for a song and $______ for a movie.
Answer:
the download cost for a song is $1 and $11 for a movie
Step-by-step explanation:
According to the questions, the following equations are as follows:
Let us assume the song be x
And, the movies be y
So,
20x + 13y = $163.........(i)
13x + 13y = $156........(ii)
Now solve substract second equation from the first equation
7x = $7
x = $1
And the y value is
20 + 13y = $163
13y = $163 - $20
13y = $143
y = $11
Hence, the download cost for a song is $1 and $11 for a movie

Answer: x = 9
***If the image is sideways, use the rotate button.
Alternate exterior angles are congruent.
This means the angles are equal.
(14x - 1)° and 125° are alternate exterior angles.
(14x - 1)° = 125°
The value of x is 8.86°.
What are corresponding angles?The angles that are in the same position on two parallel lines intersected by a transversal line on the parallel lines.
Corresponding angles are equal.
We have,
The diagram:
Line k is parallel to line l.
Line t intersects line k and line l.
This means that,
(14x - 1)° and 125° are alternate exterior angles.
Alternate exterior angles are congruent.
This means the angles are equal.
We get,
(14x - 1)° = 125°
14x - 1 = 125
Add 1 on both sides.
14x - 1 + 1 = 125 + 1
14x = 124
Divide both sides by 14.
x = 124/14
x = 8.86°
Thus,
(14x - 1)° and 125° are alternate exterior angles.
(14x - 1)° = 125°
The value of x is 8.86°.

Andrew is moving from Manhattan to Brooklyn and rented a truck from U-Haul. The cost of one-day truck rental is given by
C(m)=0.50m+50
Where m is the number of miles driven. If Andrew drives 78 miles, what is the cost of the
truck rental?
Answer:
Assuming that Andrew made the trip in one day, the cost of the truck rental is $89
Step-by-step explanation:
You can find the answer essentially by plugging in 78 for every variable m: C(78)=0.50(78)+50
C(78)=39+50
C(78)=89
The cost of driving 78 miles in one day is $89.
