The tickets for the school play are $7.00 for adults and $5.00 for students. There were 100 tickets sold. If the total profit was $550.00, how many of each were sold?
Answer:
25 adult tickets and 75 student tickets were sold.
Step-by-step explanation:
Given that the tickets for the school play are $ 7.00 for adults and $ 5.00 for students, and that there were 100 tickets sold generating a total profit of $ 550.00, to determine how many of each were sold the following calculation must be performed:
100 x 5 = 500
550 - 500 = 50
7 - 5 = 2
50/2 = 25
100 - 25 = 75
(25 x 7) + (75 x 5) = X
175 + 375 = 550
Therefore, 25 adult tickets and 75 student tickets were sold.

Answer
11 inches by 8.5 inches
Step-by-step explanation:
We can use proportions to solve this problem, drawing on top, real life on bottom
1/2 inch x inches
-------------- = ----------
1 ft 22ft
Using cross products
1/2 * 22 = x*1
11 =x
11 inches
1/2 inch x inches
-------------- = ----------
1 ft 17ft
Using cross products
1/2 * 17 = x*1
8.5 =x

Gabriel went shopping for a new camera. The listed price of the camera was $37, but the price with tax came to $40.33. Find the percent sales tax.
Answer: 9% sales tax
Step-by-step explanation: 40.33-37=3.33
so, now we got to divide 3.33 by 37 (3.33/37) and that = 0.09. Now we got to do 0.09x100 and you get 9%. So basically, subtract, divide, and multiply by 100

NEED HELP AAAH!!!!!!!!
Answer:
x = 13
Step-by-step explanation:
We have the expression -26 - 2x = 13 - 5x and are asked to solve for x.
To solve we need to isolate x.
-26 -2x = 13 - 5x
Add 26 to both sides :
-2x = 39 - 5x
Add 5x to both sides :
3x = 39
Divide 3 from both sides :
x = 13

Why do you think it’s important for students to learn about math
Answer:
Step-by-step explanation:
Math is in our everyday lives. We calculate and use math in our daily lives without knowing it. By learning math, we build on useful knowledge that will help us have a better future. For example, learning how to pay taxes acquire math. Grocery shopping needs you to find the cost of the product you’re buying. When we learn math, we gain knowledge and we can pass that knowledge to our future generations so more and more people can use it to find better jobs, make your life easier, and so much more. Therefore, that is why it is important for students to learn about math.

A study is done to determine if students in the California state university system take longer to graduate than students enrolled in private universities. One hundred students from both the California state university system and private universities are surveyed. From years of research, it is known that the population standard deviations are 1.5811 years and 1 year, respectively. The following data are collected.
The California state university system students took on average 4.5 years with a standard deviation of 0.8.
The private university students took on average 4.1 years with a standard deviation of 0.2.
Required:
Conduct a hypothesis test at the 5% level.
Answer:
Step-by-step explanation:
From the given information:
sample size n = 100
Since the population is assumed to be normal. then:
[tex]\overline X _{state} - \overline X_{private} \sim N(\overline X _{state}-\overline X _{private, SD^2_{state} + SD^2_private} -2\times Cov(\overline X _{state} - \overline X_{private}})}[/tex]
[tex]\overline X _{state} - \overline X_{private} \sim N(4.5-4.1, 0.8^2 + 0.2^2 -2\times 0})}[/tex]
[tex]\overline X _{state} - \overline X_{private} \sim N(0.4, 0.68})}[/tex]
The test statistics:
[tex]z = \dfrac{\overline X_{state} - \overline X_{private} }{ \sqrt{\dfrac{\sigma^2_{state}}{n } + \dfrac{\sigma^2_{private}}{n } } }[/tex]
[tex]z = \dfrac{0.4 }{ \sqrt{\dfrac{1.5811^2}{100 } + \dfrac{1^2}{100 } } }[/tex]
z = 2.138
Using the z tables;
P-value = (Z> 2.138)
P-value = 1 - (Z<2.138)
P-value = 1 - 0.9837
P-value = 0.0163
Decision rule: to reject the null hypothesis if the p-value is less than the significance level
Conclusion: We reject the null hypothesis and conclude that there is enough evidence to conclude that the average time it requires for the students to graduate from a private university is lesser than that of the time it takes such student to graduate from the California state university system.

What is x when 44x=78
Answer:
≈ 1.77
Step-by-step explanation:
So we are looking for x in 44(x) = 78.
All we have to do is isolate the variable, get x by itself.
Divide 44 by both sides :
[tex]\frac{44x}{44} = \frac{78}{44}[/tex]
[tex]x = 1.772727272723[/tex]
Which can be rounded to ≈ 1.77
