A report about how American college students manage their finances includes data from a survey of college students. Each person in a representative sample of 793 college students was asked if they had one or more credit cards and if so, whether they paid their balance in full each month. There were 500 who paid in full each month. For this sample of 500 students, the sample mean credit card balance was reported to be $825. The sample standard deviation of the credit card balances for these 500 students was not reported, but for purposes of this exercise, suppose that it was $195. Is there convincing evidence that college students who pay their credit card balance in full each month have a mean balance that is lower than $907, the value reported for all college students with credit cards?
Required:
a. Carry out a hypothesis test using& significance level of 0.01.
b. State the appropriate null and alternative hypotheses.
Answer:
Following are the responses to the given question:
Step-by-step explanation:
Test statistic:
[tex]t=\frac{(825-905)}{\frac{205}{\sqrt{(500)}}}[/tex]
[tex]=\frac{(-80)}{\frac{205}{22.36}}\\\\=\frac{(-80)}{9.16}\\\\=-8.73[/tex]
Let the p-value=0
We reject H0 because of the p-value <0.01. We have evidence that college kids who pay their credit card bills in full per month have a mean balance of less than $905.

Step 1: Define

[tex]\displaystyle f(x) = \left\{\begin{array}{ccc}5 - x ,\ x < 5\\8 ,\ x = 5\\x + 3 ,\ x > 5\end{array}[/tex]
Step 2: Find Left-Side Limit
Substitute in function [Left-Side Limit]: [tex]\displaystyle \lim_{x \to 5^-} 5 - x[/tex]Evaluate limit [Limit Rule - Variable Direct Substitution]: [tex]\displaystyle \lim_{x \to 5^-} 5 - x = 5- 5 = 0[/tex]Step 2: Find Left-Side Limit
Substitute in function [Right-Side Limit]: [tex]\displaystyle \lim_{x \to 5^+} x + 3[/tex]Evaluate limit [Limit Rule - Variable Direct Substitution]: [tex]\displaystyle \lim_{x \to 5^+} x + 3 = 5 + 3 = 8[/tex]∴ since [tex]\displaystyle \lim_{x \to c^+} f(x) \neq \lim_{x \to c^-} f(x)[/tex] , [tex]\displaystyle \lim_{x \to 5} f(x) = \text{DNE}[/tex]

Plz help me quickly it’s due very soon!!!!
Answer:
Step-by-step explanation:
Both angles together equal 180. Set up your formula as
-4x+5+-13x+39 = 180
Now move your terms to have all x values on one side
-4x-13x = 180-5-39
-17x = 136
x=136 / -17
Use this answer in place of your x in each equation to get the angle.
You got this!
Find the value of X

Gabriel earns $146.25 for working 15 hours. Maria earns $205.00 for working 20 hours. Who earns the most money per hour and how much more?
Please help have to turn in tomorrow
you get 15 points!!!!
Answer: Maria makes $0.50 more per hour
Step-by-step explanation: Doing $146.25/15 and $205/20 you can find that Gabriel makes $9.75/hr and Maria makes $10.25/hr
Answer: Maria makes more, 50 cents more per hour.
Step-by-step explanation:
To solve divide the number of money they made by the amount of hours they worked. 146.25/15=9.75. Gabriel made 9.75 an hour,
205/20=10.25 Maria made 10.25 an hour.
Maria earned the most money per hour.
To find how much more she made subtract the person who made more money by the person who made less money per hour. 10.25-9.75=0.5 Maria earned an extra 50 cents per hour compared to Gabriel.

Answer:
The company's expenses and sales will both total $2944 once they have sold 736 oz of links
Step-by-step explanation:
cost: y = 736 + 3x
revenue: y = 4x
y = y, so using substitution
4x = 3x + 736
x = 736
They will therefore need to sell 736 oz of links, and when plugging in 736 as x into both the equations:
y = 736 + 3(736) = 2944
y = 4(736) = 2944

Emilio is drawing a graph that shows the weight of a baby elephant during the first 6 months of its life. What is the meaning of the point shown on the graph?
Ruby's Weight
A graph has age (months) on the x-axis, and weight (pounds) on the y-axis. A point is at (1, 80).
Using the function concept, it is found that the meaning of the point is that the weight of the elephant during the first month is of 80 pounds.
What is a function?In a function, represented by a set of ordered points (x,y), one value of the input x can be related to only one value of the output y.
In this problem, x is the age in months, while y is the weight in pounds, hence the meaning of point (1,80) is that the weight of the elephant during the first month is of 80 pounds.

2.The marked price of television is Rs2000.If 13 percentage tax was levied, after allowing 10 percentage discount, find the final price.Single choice.
(2 Points)
Answer:
Final price = $2034
Step-by-step explanation:
Given the following data;
Marked price = $2000
Tax = 13%
Discount = 10%
To find the final sales price;
First of all, we would calculate the discount price
Discount price = 10/100 * 2000
Discount price = 20 * 10 = $200
New Price = marked price - discount price
New Price = 2000 - 200 = 1800
Next, we calculate the tax on the product;
Tax = 13/100 * 1800
Tax = 0.13 * 1800
Tax = $234
Finally, we would determine the final price;
Final price = marked price + Tax
Final price = 1800 + 234
Final price = $2034
1 8 The scale blueprint of a rectangular pool is drawn inch - 1 foot. If the pool is 34 feet long, what is the measure of the pool's length on the blueprint? A) 3.5 in B) 3.75 in C) 4.25 in D) 4.5 in E) 4.75 in
Answer:
C
Step-by-step explanation:
The scale blueprint of a rectangular pool is drawn 1/8 in - 1 foot. If the pool is 34 feet long, what is the measure of the pool's length on the blueprint
A scale drawing is a reduced form in terms of dimensions of an original image / building / object
the scale drawing is usually reduced at a constant dimension
scale of the drawing = original dimensions / dimensions of the scale drawing
Blueprint's length = 34 x 1/8 = 4.25

Answer:
[tex](x,y) = (-1,-2.5)[/tex]
Step-by-step explanation:
Let be [tex]f(x) = \frac{(x+3)^{2}}{x-2}[/tex] and [tex]g(x) = \left|\frac{x}{2}\right| -3[/tex], we plot each curve with the help of graphic tool. In this case, we use Desmos and outcome is presented in the image attached below. Mathematically speaking, a solution to the system of equation exists when [tex]f(x) = g(x)[/tex]. Graphically speaking, it means that a solution exists when both curves pass through each other.
According to the graphic tool, we conclude that the only solution to the system of equations is [tex](x,y) = (-1,-2.5)[/tex].
