On Saturday, many tickets for a hockey game were sold. Children and adult tickets were sold in the ratio of 4:7. There are 88 tickets in total.
How many adult tickets were sold?
Answer:
49 tickets
Step-by-step explanation:
THis is pretty straight forward
So we have the ratio 4:7
We know there were 88 tickets in total but we don’t know the exact amount of adult and kids
So we can Add up the ratio
4+7=11
Now we can divide 88 by 11
you’ll get 7
So by doing this we know there are 7 groups of the ratio for child to adults 4:7
So we just multiply the 7 to each
4*7
7*7
you’ll get 28:49
Now we know there are 28 kid tickets and 49 adult tickets
We know this is correct becuase if you add up the ratio, it’ll be 88
Which is the same as the amount fo people at the hockey game

Answer: 384 ft^2
Step-by-step explanation:
Like it said set up a proportional equation and solve for dimensions in feets.
The scale factor saids 0.75 in = 2 ft
And the dimensions are 6 in by 9 in
Now using the scale solve for how many feets will make 6 inches and how many feets will make 9 inches .
[tex]\frac{0.75}{6} = \frac{2}{x}[/tex] Solve by cross multiplying
0.75x = 12
x = 16
[tex]\frac{0.75}{9} = \frac{2}{x}[/tex] Cross multiply
0.75x = 18
x = 24
Now since we know the new dimensions are 16ft by 24ft then we will multiply them together to find the area .
16 * 24 = 384 ft^2

A consumer group wants to know if an automobile insurance company with thousands of customers has an average insurance payout for all their customers that is greater than $500 per insurance claim. They know that most customers have zero payouts and a few have substantial payouts. The consumer group collects a random sample of 18 customers and computes a mean payout per claim of $579.80 with a standard deviation of $751.30. Is it appropriate for the consumer group to perform a hypothesis test for the mean payout of all customers
It isn't appropriate for the consumer group to perform a hypothesis test for the mean payout of all customers.
The major reason is because the sample is short and it is given that most consumer has zero payouts.
What do we know?Most customers have zero payouts and a few have substantial payoutsSample size = 18Sample mean = $579.80Sample variance = $751.30How to know if it is appropriate to perform hypothesis testing?The size of the sample taken is not enough large. When sample isn't large enough, it represents skewed information of the population.
The population itself contains many customers who have zero payouts, thus the population isn't normally distributed for insurance claim.
Because of these reasons, the sample mean won't help in deducing conclusions about population mean.
Thus, it is inappropriate for the consumer group to perform a hypothesis test for the mean payout of all customers.

It is not appropriate to perform a hypothesis test for the mean payout of all customers, mostly because the sample is really small.
What do we know?Most customers have zero payouts and a few have substantial payouts Sample size = 18 Sample mean = $579.80 Sample variance = $751.30What does this imply?
The first thing you can see is the sample size, it seems to be really small for a company with thousands of customers, is really probably that just 18 of them do not represent accurately the whole population.
We also do know that a large proportion of the population has zero payouts, so the population is skewed.
Just because of these two motives, the mean of the sample most likely does not accurately portray the whole population, thus is not appropriate for the consumer group to perform a hypothesis test for the mean payout of all customers.

A 1000-liter tank initially contains a mixture of 450 liters of cola and 50 liters of cherry syrup. Cola is added at the rate of 8 liters per minute, and cherry syrup is added at the rate of 2 liters per minute. At the same time, a well mixed solution of cherry cola is withdrawn at the rate of 5 liters per minute. Let S(t) be the amount (measured in liters) of cherry syrup in the tank at time t, where t is measured in minutes.(a) Formulate an initial-value problem for the the amount of cherry syrup in the tank overtime.(b) Solve the initial-value problem using an integrating factor.(c) What percentage of the mixture is cherry syrup when the tank is full?
Answer:
A) dS/dt = 2 - S/(100 + t) ; S(0) = 50
B) S(t) = (100 + t) - 5000/(100 + t)
C) 35%
Step-by-step explanation:
A) Let;
t = time in minutes
S = amount of syrup
dS/dt = rate at which syrup is flowing through tank
We are told that initially, the tank contains a mixture of 450 liters of cola and 50 liters of cherry syrup.
Thus,
At t = 0
Amount of cola = 450 litres
Amount of syrup = 50 litres
Total mixture = 450 + 50 = 500 litres
We are told that a well mixed solution of cherry cola is withdrawn at the rate of 5 liters per minute.
Thus, amount of liquid in the tank at a time "t" is; 500 + 5t
We are told that cherry syrup is added at the rate of 2 liters per minute.
Thus, rate at which syrup is flowing through tank is given as;
dS/dt = 2 - 5[S/(500 + 5t)]
Factorizing out, we have;
dS/dt = 2 - 5[S/5(100 + t)]
5 will cancel out to give;
dS/dt = 2 - S/(100 + t)
Since we have 50 liters of cherry syrup initially, the initial value problem is;
dS/dt = 2 - S/(100 + t) ; S(0) = 50
B) We have our initial value problem as;
dS/dt = 2 - S/(100 + t)
Rearranging, we have;
dS/dt + S/(100 + t) = 2
Multiplying through by 100 + t gives;
(dS/dt)•(100 + t) + S = 2(100 + t)
Integrating each term with respect to t gives;
(100 + t)S = (100 + t)² + c
Divide both sides by (100 + t) to get;
S = (100 + t) + c/(100 + t)
At t = 0;
S(0) = (100 + 0) + c/(100 + 0)
S(0) = 100 + c/100
Recall earlier in our initial value problem where we stated that S(0) = 50.
Thus;
100 + c/100 = 50
Subtract 100 from both sides to givw;
c/100 = 50 - 100
c/100 = -50
c = -50 × 100
c = -5000
Thus;
S(t) = (100 + t) - 5000/(100 + t)
C) The capacity of the tank is given as 1000 liters.
Earlier, we saw that amount of liquid in the tank at a time "t" is; 500 + 5t
Thus;
500 + 5t = 1000
5t = 1000 - 500
5t = 500
t = 500/5
t = 100 minutes
We want to find What percentage of the mixture is cherry syrup when the tank is full.
Thus we will plug in t = 100 minutes into S(t) = (100 + t) - 5000/(100 + t)
Thus;
S(100) = (100 + 100) - 5000/(100 + 100)
S(100) = 200 - 25
S(100) = 175 litres
We saw earlier that total mixture initially was 500 litres.
Thus, percentage of the mixture that is cherry syrup when the tank is full is;
175/500 × 100% = 35%

Margaret is completing a lifeguard course and is completing the test at the end of the
course. There are 75 total questions that she needs to complete and she is 36% complete.
How many more cuestions does she need to complete
Q
Answer:
Step-by-step explanation:
For your first question,
Total percentage of people cheering for visiting team = 45%
Total percentage of people cheering for home team = 55%
Total number of people cheering = 1200
Therefore, the number of people cheering for visiting team = 45% of 1200
= [tex]\frac{45}{100}[/tex] × 1200
= 45 × 12
= 540 people
For your second question,
Total number of questions = 75
Total percentage of the number of questions he completed = 36%
Percentage of the amount of questions left = 100 - 36 = 64%
Therefore, the number of questions left to complete = 64% of 75
= [tex]\frac{64}{100}[/tex] × 75
= [tex]\frac{64}{20}[/tex] × 15
= [tex]\frac{64}{4}[/tex] × 3
= 16 × 3
= 48 questions are left

Answer:
a. 8.5
b. 10
Step-by-step explanation:
a.) 1, 1, 2, 7, 7, 10, 12, 16, 20, 34
Since 7 and 10 are tied in the middle, then we need to find a number in the middle of the two.
8.5 is in the middle of 7 and 10, therefore 8.5 is the mean.
b.) We need to do the same thing we did before, except add 22 to it's directed place:
1, 1, 2, 7, 7, 10, 12, 16, 20, 22, 34
Since 10 is in the middle, 10 is the new mean.

If RSTU is a rhombus, find the measure of angle RUT.
Finding x:
We know that the diagonals of a rhombus bisect its angles
So, since US is a diagonal of the given rhombus:
∠RUS = ∠TUS
10x - 23 = 3x + 19 [replacing the given values of the angles]
7x - 23 = 19 [subtracting 3x from both sides]
7x = 42 [adding 23 on both sides]
x = 6 [dividing both sides by 7]
Finding ∠RUT:
We can see that:
∠RUT = ∠RUS + ∠TUS
Since we are given the values of ∠RUS and ∠TUS:
∠RUT = (10x - 23) + (3x + 19)
∠RUT = 13x - 4
We know that x = 6:
∠RUT = 13(6)- 4
∠RUT = 74°

Answer:
option 1
Step-by-step explanation:
It's given in the question that
a (first term of an A.P.) = 14
d (common difference between terms of A.P.) = -3
So,
2nd term will be = a + d = 14 + (-3) = 11
3rd term = a + 2d = 14 + 2×(-3) = 8
4th term = a + 3d = 14 + 3×(-3) = 5
All these terms are matching with option 1. So, option 1 is the correct option
