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.

Answer:
z>-4
Step-by-step explanation:
Answer:
z>4
Step-by-step explanation:
-2z-3<5
add 3 to 5: -2z < 8
divide by -2: z < -4
but since you divided by a negative number, you have to change the way the inequality is facing so the answer is z>-4
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.

Step-by-step explanation:
after 4 hours, the water level decreased by 8 feet
which is -8
Therefore -8/4 = -2 change in water level every hour
Answer:
The constant rate of change is 2 feet every hour.
Step-by-step explanation:
Since the level of the water was at 10 feet at 2 pm, and the water at 6 pm was at 2 feet, the water level dropped 8 feet in 4 hours.
With this information we can create the ratio 4:8 and when you simplify the ratio down to 1, you get 1:2
1 Representing 1 hour
2 Representing 2 feet
Every hour, the water level drops 2 feet.
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)

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.

What is division?It is the basic arithmetic operation, in which you are separating the number into some parts.
Given data:
A recipe for cake calls for a ratio of 1 cup of sugar for every 2 cups of flour.
Calculate the ratio for 1 cake
1 cup of sugar / 2 cups of flour
Calculate the sugar and flour for 3 cake
1 cup of sugar / 2 cups of flour × 3
3 cups of sugar / 6 cups of flour
Therefore, 3 cups of sugar and 6 cups of flour are required to bake the cake if for cake calls for a ratio of 1 cup of sugar for every 2 cups of flour.
