Heather's school is selling tickets to the annual dance competition. On the first day of ticket sales the school sold 6 adult tickets and 7 student tickets for a total of $120. The school took in $168 on the second day by selling 12 adult tickets and 2 student tickets. Find the price of an adult ticket and the price of a student ticket.
Answers
Answer:
Price of adult ticket = x = $13
Price of student ticket = y = $6
Step-by-step explanation:
Let Price of adult ticket = x
Price of student ticket = y
Now, making equations:
On the first day of ticket sales the school sold 6 adult tickets and 7 student tickets for a total of $120. The equation will be:
[tex]6x+7y=120[/tex]
The school took in $168 on the second day by selling 12 adult tickets and 2 student tickets. The equation will be:
[tex]12x+2y=168[/tex]
Now, solving the equations simultaneously to find values of x and y.
Let:
[tex]6x+7y=120--eq(1)\\12x+2y=168--eq(2)[/tex]
Multiply eq(1) by 12 and then subtract both equations
[tex]12x+14y=240\\12x+2y=168\\-\:\:\:-\:\:\:\:\:\:\:\:\:-\\--------\\12y=72\\y=\frac{72}{12}\\y=6[/tex]
So, we get value of y: y=6
Now, Put value of y in equation 1 to find value of x
[tex]12x+2y=168\\Put\:y=6\\12x+2(6)=168\\12x+12=168\\12x=168-12\\12x=156\\x=\frac{156}{12}\\x=13[/tex]
So, we get value of x: x=13
The answer would be:
Price of adult ticket = x = $13
Price of student ticket = y = $6

f(x) =2x+4 translate 7 units left
Answers
Answer:
[tex]f'(x) = 2x - 10[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 2x + 4[/tex]
Required
Translate 7 units left
When a function f(x) is translated b units to the left, the resulting function is:
[tex]f'(x) = f(x-b)[/tex]
In this case:
[tex]f(x) = 2x + 4[/tex]
[tex]b = 7[/tex]
[tex]f'(x) = f(x-b)[/tex] becomes
[tex]f'(x) = f(x - 7)[/tex]
Calculating [tex]f(x-7)[/tex]
[tex]f(x-7) = 2(x-7)+4[/tex]
[tex]f(x-7) = 2x-14+4[/tex]
[tex]f(x-7) = 2x-10[/tex]
So:
[tex]f'(x) = 2x - 10[/tex]

The final exam grade of a statistics class has a skewed distribution with mean of 79 and standard deviation of 8.2. If a random sample of 35 students selected from this class, then what is the probability that average final exam grade of this sample is between 76 and 82
Answers
Answer:
0.9696
Step-by-step explanation:
Given that:
Mean, m = 79
Standard deviation, s = 8.2
Sample size, n = 35
Probability that final exam grade of the sample is between 76 and 82
P(76 < x < 82)
P(x < 82) - P(x < 76)
Using the relation :
Z = (x - m) / (s/sqrt(n))
s / sqrt(n) = 8.2/sqrt(35) = 1.3860529
P(x < 82) - P(x < 76)
P[(82 - 79) / 1.3860529] - P[(76 - 79) / 1.3860529]
P(Z < 2.1644) - P(Z < - 2.1644)
Using the Z probability calculator :
0.98478 - 0.015217
= 0.969563
Hence, probability = 0.9696

Answers
Given :
Actual length of the bolt is 2.5 inches.
Measured length of the bolt is 2.6 inches.
To Find :
The percent error of the bolt.
Solution :
We know, percentage error is given by :
[tex]\delta =| \dfrac{Actual\ Value - Expected\ Value}{Expected\ Value}|\times 100\\\\\delta =| \dfrac{2.6-2.5}{2.5}|\times 100\\\\\delta = 4 \%[/tex]
Therefore, the percentage error in the bolt is 4% .

Alex is tracking how many computers he can fix in an afternoon. He listed the number of computers fixed per hour in the following table: Hour (x) Number of Customers f(x) 1 4 2 8 3 12 Determine if these data represent a linear function or an exponential function, and give the common difference or ratio.
Answers
This is a linear function because there is a common difference of 4
⇒ 2nd answer
Step-by-step explanation:
- In the linear function there is a common difference between each two
consecutive data
- In the exponential function there is a common ratio between each two
consecutive data
- Lats check the data in the data in the table
(x) === 1 ⇒ 2 ⇒ 3
f(x) === 4 ⇒ 8 ⇒ 12
∵ x has consecutive numbers 1 , 2 , 3
∵ 8 - 4 = 4
∵ 12 - 8 = 4
∴ f(x) has a common difference 4
∵ 8 ÷ 4 = 2
∵ 12 ÷ 8 = 1.5
∴ f(x) has no common ratio
∴ The table represents a linear function with common difference 4
This is a linear function because there is a common difference of 4
