Mrs. Nez owns a small business. When her customers pay with
a credit card, she receives 95.8% of the charged amount from
the credit card company. If a customer makes a $20 purchase,
how much will Mrs. Nez receive from the credit card company?
Answer:
the amount received from the credit card company is $19.16
Step-by-step explanation:
The computation of the amount received from the credit card company is shown below:
= Purchase made by the customer × received percentage
= $20 × 95.8%
= $19.16
Hence, the amount received from the credit card company is $19.16

A sample survey of 62 discount brokers showed that the mean price charged for a trade of 100 shares at $50 per share was $31.22. The survey is conducted annually. With the historical data available, assume a known population standard deviation of $19. (a) Using the sample data, what is the margin of error in dollars associated with a 95% confidence interval? (Round your answer to the nearest cent.) $ (b) Develop a 95% confidence interval for the mean price in dollars charged by discount brokers for a trade of 100 shares at $50 per share. (Round your answers to the nearest cent.) $ to $
Answer:
a) The margin of error associated with a 95% confidence interval is of $4.73.
b) $26.49 to $35.95
Step-by-step explanation:
Question a:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1-0.95}{2} = 0.025[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1-\alpha[/tex].
So it is z with a pvalue of [tex]1-0.025 = 0.975[/tex], so [tex]z = 1.96[/tex]
Now, find the margin of error M as such
[tex]M = z*\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
[tex]M = 1.96*\frac{19}{\sqrt{62}} = 4.73[/tex]
The margin of error associated with a 95% confidence interval is of $4.73.
Question b:
The lower end of the interval is the sample mean subtracted by M. So it is 31.22 - 4.73 = $26.49
The upper end of the interval is the sample mean added to M. So it is 31.22 + 4.73 = $35.95
So $26.49 to $35.95

Step-by-step explanation:
For the base of the triangles, we just have to remove the 1m and divide the remaining measurement into two since they are symmetrical.
[tex]5m - 1m = 4m \\ \frac{4m}{2} = 2m \: each[/tex]
For the area of the rectangle:

For the area of each triangle:

At which value in the domain does f(x) = 0?
Answer: C (x=1)
Step-by-step explanation:
f(x)=0 at points of intersection of the graph of the function with x-axis.
The graph of the function intersects x-axis at three points:
somewhere between -3 and -2;
somewhere between -1 and 0;
at x=1.
Since x=1 is the value of x from the domain, then correct choice is option C.

A merry go round rotates 2808 degrees per ride. How far would a rider seated 8 feet from the center of the merry go round travel during the ride?
Answer:
Step-by-step explanation:
2880° per ride doesn't make sense, because it is not a whole number.
Do you mean 2880° per ride?
r = 8 feet
circumference = 2πr = 16π feet
2880° × (16π feet)/(360°) = 128π feet ≅ 402 feet
A rider seated 8 feet from the merry-go-center round would travel 392.2 feet during the ride.
What is circumference?The circumference is the distance that surrounds a circle. We can measure the circumference of the earth by measuring the distance that we will have to walk all the way around the world.
Given, A merry go round rotates 2808 degrees per ride. A rider is seated 8 feet from the center.
Thus r = 8 feet
Circumference = 2πr
Circumference = 2π*8
Circumference = 16π
Distance traveled by that man = 2808* 16π/360
Distance traveled by that man = 392.22 feet
therefore, a rider seated 8 feet from the center of the merry-go travel during the ride would travel 392.2 feet.

Answer:
The factors of given quadratic equation
[tex]x = \frac{9}{15} and x = -2[/tex]
Step-by-step explanation:
Explanation:-
Given quadratic equation 15x² +39 x -18 =0
The factors of 270 = 30 × 9
The quadratic equation 15x² +39 x -18 =0
⇒ 15 x² +30 x-9x -18=0
⇒ 15x(x+2) -9( x+2) =0
⇒( 15x -9)(x+2) = 0
15x - 9=0 and x+2 =0
15 x =9 and x = -2
