Answer:
156 children145 adultsStep-by-step explanation:
Let number of adults be a and children be c
Then we have equations
a + c = 3014a + 1.5c = 814From the first equation we get a = 301 - c, we substitute a in the second equation:
4(301 -c) + 1.5c = 8141204 - 4c + 1.5c = 8142.5c = 1204 - 8142.5c = 390c = 390/2.5c = 156Then finding the value of a:
a = 301 - 156 = 145Ray is buying some ginger roots to brew some fresh ginger ale. The price of the ginger roots is GGG, and Ray has a coupon for 10\%10%10, percent off. The expression 0.99, G represents the price Ray pays for the ginger roots after using the coupon. What does 0.90, 9 represent in this context?
Answer:
0.9 in the context represent the price of the ginger
It is called decreasing factor for the function because it decreases the price of the ginger
Step-by-step explanation:
Original price of fresh ginger ale = G
Coupon = 10% off
The actual price paid = 100% - 10% of G
= 90% of G
= 90/100 × G
= 0.9 × G
= 0.9G
0.9 in the context represent the price of the ginger
It is called decreasing factor for the function because it decreases the price of the ginger

Brandi spent 25 mins, which is 5/8 of her class period taking notes. How long was the class period?
Answer:
The class period was 45 minutes long
Step-by-step explanation:
as you can see 5/8 of the class is 25 minutes, meaning that 1 = 5 if we multiply 8 times 5, it gives 45.
Answer: I believe your answer is 40 minutes for Brandi's class period.
Step-by-step explanation: For every 5 minutes she spends in class, it is 1/8 of her total period of class time. For example, she spent 25 minutes and has 15 minutes or 3/8 left of class.

Solve : x+1 = 0
Subtract 1 from both sides of the equation :

Solve for x
Step-by-step explanation:
A paint company claims their paint will be completely dry within 45 minutes after application. Recently, customers have complained drying times are longer than the claimed 45 minutes. A consumer advocate group takes a random sample of 25 paint specimens and records their drying times. The average drying time x is 52. Consider dryng time, for all test specimens, to be normally distributed with ? = 6.
Suppose the claimed drying time is true, that is ? = 45 minutes, what is the probability of observing a sample mean of x = 52 or greater from a sample size of 25? (Round your answer to four decimal places.)
Answer:
The probability of observing a sample mean of x = 52 or greater from a sample size of 25 is 0.0000026
Step-by-step explanation:
Mean = [tex]\mu = 45[/tex]
Population standard deviation =[tex]\sigma = 6[/tex]
Sample size = n =25
Sample mean = [tex]\bar{x} = 52[/tex]
We are supposed to find the probability of observing a sample mean of x = 52 or greater from a sample size of 25 i.e.[tex]P(x\geq 52)[/tex]
[tex]Z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}\\Z=\frac{52-45}{\frac{6}{\sqrt{25}}}[/tex]
Z=5.83
P(Z<52)=0.9999974
[tex]P(Z\geq 52)=1-P(z<52)=1-0.9999974=0.0000026[/tex]
Hence the probability of observing a sample mean of x = 52 or greater from a sample size of 25 is 0.0000026
Answer:
the probability of observing a sample mean of x = 52 or greater from a sample size of 25 is 0.0000026

Answer:
7 1/2 ÷ 1 1/2
make them improper fractions;
15/2 ÷ 3/2
make 3/2 a reciprocal(basically flipping the fraction upside down)
15/2 ÷ 2/3
and multiply across;
15/2 x 2/3 = 30/6 which simplifies to 5 bags of flour.

There is $74 Michael deposit from each paycheck if the payback os bi-weekly, the correct option is B.
What is the insurance?The insurer and the insured get a legal contract for the insurance, which is called the insurance policy.
Given
Car insurance premium in a first half year = $958
Car insurance premium in the second half year = $958
Total Car insurance premium in year = 2 × $958 = $ 1916
Nature of paid premium is bi-weekly = in 2 weeks
There are total 52 weeks in a year.
The total number of bi-week = 26
Total deposited amount per bi-weekly is;
= $ 1916 ÷ 26 =$ 73.69 ≈ $ 74

The soccer team's shirts have arrived in a big box, and people just start grabbing them, looking for the right size. The box contains 6 medium, 10 large, and 10 extra-large shirts. A player wants a medium for himself and one for his sister. Find the probability of each event described. Complete parts a through d below.
a) Probability of getting a medium shirt for the player ≈ 0.0385
b) Probability of getting a medium shirt for the player's sister ≈ 0.0385
c) Probability of getting a medium shirt for both the player and his sister ≈ 0.00148225
d) Probability of getting either a medium, large, or extra-large shirt ≈ 0.0385.
Here, we have,
To find the probability of each event, we first need to determine the total number of shirts in the box and the number of shirts that satisfy each event.
a) Probability of getting a medium shirt for the player:
Total number of medium shirts = 6
Number of medium shirts needed for the player = 1
Probability = (Number of medium shirts needed) / (Total number of shirts) = 1 / (6 + 10 + 10) = 1 / 26 ≈ 0.0385
b) Probability of getting a medium shirt for the player's sister:
Total number of medium shirts = 6
Number of medium shirts needed for the player's sister = 1
Probability = (Number of medium shirts needed) / (Total number of shirts) = 1 / (6 + 10 + 10) = 1 / 26 ≈ 0.0385
c) Probability of getting a medium shirt for both the player and his sister:
Since the two events are independent (one person getting a medium shirt does not affect the other's chance of getting a medium shirt), we can multiply the probabilities of each event:
Probability = Probability of player getting a medium shirt * Probability of player's sister getting a medium shirt ≈ 0.0385 * 0.0385 ≈ 0.00148225
d) Probability of getting either a medium, large, or extra-large shirt:
Total number of medium, large, and extra-large shirts = 6 + 10 + 10 = 26
Number of shirts needed = 1 (for the player or his sister)
Probability = (Number of shirts needed) / (Total number of shirts) = 1 / 26 ≈ 0.0385
To summarize:
a) Probability of getting a medium shirt for the player ≈ 0.0385
b) Probability of getting a medium shirt for the player's sister ≈ 0.0385
c) Probability of getting a medium shirt for both the player and his sister ≈ 0.00148225
d) Probability of getting either a medium, large, or extra-large shirt ≈ 0.0385.
