A movie theater charges $10.50 per ticket and $5 per bucket of popcorn. You never buy the popcorn because you think it's too expensive.
Is the total price you pay proportional to the number of tickets you buy?
Yes, the total price pay is proportional to the number of tickets.
What is proportionality?In mathematics, proportionality indicates that two quantities or variables are related in a linear manner.
Since you never plan to buy the popcorn but only the movie ticket, therefore we can definitely say that there is a direct correlation between the total price and the number of tickets bought.
Since, 1 ticket = $10.50
So,
The proportion equation is:
P = 10.50 t
where P is the total price and t is the number of tickets
Hence, the total price pay is proportional to the number of tickets.

Xavier worked 10 hours on Monday and 15 hours on Wednesday. His total pay was 280.00 what is his rate per hour
Xavier's rate per hour is $11.20.
What is unit rate?A unit rate means a rate for one of something. We write this as a ratio with a denominator of one. For example, if you ran 70 yards in 10 seconds, you ran on average 7 yards in 1 second. Both of the ratios, 70 yards in 10 seconds and 7 yards in 1 second, are rates, but the 7 yards in 1 second is a unit rate.
Given that, Xavier worked 10 hours on Monday and 15 hours on Wednesday. His total pay was 280.00
Number of hours worked on Monday = 10 hours
Number of hours worked on Tuesday = 15 hours
Total pay received by Xavier = $280
Total number of hours worked = (10 + 15) = 25 hours
Therefore, Rate per hour = 280/25 dollars per hour
Hence, Xavier's rate per hour is $11.20.

Which statements about doubling an investment are true? Check all that apply.
An investment of $5,000 will double in 6 years at an annual compound interest rate of 12%.
An investment of $1,000 will double at an annual compound interest rate of 18% in 6 years.
An investment of $350 will double in 9 years at a compound interest rate of 8%.
An investment of $2,000 will double at a simple interest rate of 5% in 20 years.
An investment of $700 will double in 12 years at a simple interest rate of 6%.
this is the correct answer
Answer:
statement A, C, D, are true.
Step-by-step explanation:
We check all the statements by the rule of 72 to find which statement about doubling an investment are true.
Formula we use = [tex]\frac{72}{R}[/tex] R = Rate of interest
Statement A :
An investment of $5,000 will double in 6 years at an annual compound interest rate of 12%.
[tex]\frac{72}{12}[/tex] = 6 years
It will take 6 years to double the investment. This statement is true.
Statement B :
An investment of $1000 will double at an annual compound interest rate of 18% in 6 years.
[tex]\frac{72}{18}[/tex] = 4 years
It will take 4 years to double the investment. This statement is not true.
Statement C:
An investment of $350 will double in 9 years at a compound interest rate of 8%.
[tex]\frac{72}{8}[/tex] = 9 years
It will take 9 years to double the investment. This statement is true.
Statement D :
An investment of $2000 will double at a simple interest rate of 5% in 20 years.
Formula for Simple interest = (PRT)
I = (2000 × 0.05 × 20) = $2000
So the amount will be 4000 in 20 years. This statement is true.
Statement E :
An investment of $700 will double in 12 years at a simple interest rate of 6%
Interest = ( 700 × 0.06 × 12 ) = $504
Amount after 12 years 700 + 504 = $1204. This statement is not true.

A teacher wants to calculate a class average on the last test. One student made a significantly lower score than the rest of the class because he failed to follow instructions. Which measure of center would be best for the teacher to use to get an accurate idea on how well the class as a whole performed on the last test?
A. mode
B. median
C. mean
D. range
Final answer:
The median is the best measure of center for the teacher to use to evaluate the overall performance of the class on a test when the data set includes an outlier.
Explanation:
The most appropriate measure of center for the teacher to use in this situation is the median. This is because the median is the best measurement when a data set contains outliers or extreme values that could significantly skew the mean. Since the dataset contains a student score that is significantly lower due to not following instructions, the median would provide a more accurate idea of how the class as a whole performed, as it is less affected by this outlier. On the other hand, the mode might not be as informative if most of the scores are unique, and the mean would be substantially affected by the low score. The range is a measure of spread, not center, and therefore not suitable for determining the average performance.

The school gym can hold no more than 650 people. The bleachers will seat 176 people. The PTA is setting up 25 rows of chairs for their meeting. At most, how many chairs can be in each row?
A) 18
B) 19
C) 26
D) 27
Answer:
A)18

trey made 12 out of 30 free throw shots on the basketball court. if he attempts 75 free throw shots, how many could be expect to make
Trey can expect to make approximately 30 out of 75 free throw shots based on his previous success rate of 12 out of 30 shots.
To find how many free throws Trey might make out of 75 attempts, we use the proportion of his successful shots in the initial 30 attempts. Trey made 12 out of 30 shots, which is a success rate of [tex]\( \frac{12}{30} = \frac{2}{5} \).[/tex] We can expect him to maintain this rate over 75 shots:
[tex]\[ \text{Expected shots made} = \left( \frac{2}{5} \right) \times 75 = \frac{2 \times 75}{5} = 30 \][/tex]
Therefore, Trey can expect to make approximately 30 free throws out of 75 attempts. This estimation assumes his skill level and shooting conditions remain consistent throughout the attempts.
This calculation is a basic projection and doesn't account for potential variations in Trey's performance. Factors such as fatigue, practice, and pressure can influence his actual performance. However, it provides a reasonable estimate based on his past performance.
Using this estimate, coaches or analysts can make rough predictions about Trey's potential scoring contribution from free throws in a game or practice session, helping them plan strategies accordingly.

Solve the equation for the variable specified.
mn+7p=8 for p
To solve the equation mn + 7p = 8 for p, subtract mn from both sides to get 7p = 8 - mn, then divide by 7 to isolate p, resulting in p = (8 - mn) / 7.
Explanation:To solve the equation mn + 7p = 8 for p, we need to isolate p on one side of the equation. We can do this by performing the following steps:
Subtract mn from both sides of the equation to get 7p = 8 - mn.Divide both sides of the equation by 7 to solve for p: p = (8 - mn) / 7.Now, the variable p is isolated, and the equation shows p in terms of m and n.
The provided reference solution and the graphing technique are not directly applicable to this algebra problem, as they pertain to different cases with specific contexts such as elasticity and supply-demand curves. For the actual question at hand, we focused exclusively on algebraic manipulation to find the value of p.
