Carlos bought a new computer printer for $110.50 and some ink cartridges
for $8.25 each. He spent a total of $176.50.
The equation $176.50 = $110.50 + $8.25c can be used to solve this
problem. Which two mathematical operations do you need to perform in
order to solve the equation for c?
A. addition and multiplication
B. division and multiplication
C. subtraction and division
D. multiplication and subtraction
Answers
This is because to solve for C you need to isolate it. So you subtract 110.50 to both sides and then divide the product by 8.25 to get C. Therefore you subtract and divide to solve the equation for C.

Write the equation for a line that is parallel to the line y=-1/3x -4 and passes through the point (3, -1)
Answers
Answer:
y = -1/3x
Step-by-step explanation:
Since the line has to be parallel, that means it will have the same slope. So, we use the given point and slop to solve for the new y= mx + b using the equation y - y = m( x - x)
m= -1/3 x = 3 y = -1
y + 1 = -1/3(x - 3)
y + 1 = -1/3x + 1
y = -1/3x

A random sample of 10 employees of a company was selected to estimate the mean one-way commute time for all employees at the company. The mean and standard deviation of the sample were 38 minutes and 6 minutes, respectively. Assuming all conditions for inference are met, which of the following is the margin of error, in minutes, for a 95 percent confidence interval for the population mean one-way commute time? 1.812(610√) 1.812 times the fraction with numerator 6, and denominator the square root of 10 A 1.833(610√) 1.833 times the fraction with numerator 6, and denominator the square root of 10 B 1.96(610√) 1.96 times the fraction with numerator 6, and denominator the square root of 10 C 2.228(610√) 2.228 times the fraction with numerator 6, and denominator the square root of 10 D 2.262(610√)
Answers
Answer:
The margin of error is of [tex]2.262\frac{6}{\sqrt{10}} = 4.29[/tex]
Step-by-step explanation:
We have the standard deviation for the sample. So the T-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 10 - 1 = 9
95% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 9 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.95}{2} = 0.975[/tex]. So we have T = 2.262
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 2.262\frac{6}{\sqrt{10}} = 4.29[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The equation that represents the margin of error is: [tex]E = 2.262 \times \frac{6}{\sqrt {10}}[/tex]
The given parameters are:
Sample size = 10Mean = 38Standard deviation = 6Confidence Interval = 95%The margin of error is calculated using:
[tex]E = z_y \times \frac{\sigma}{\sqrt n}[/tex]
So, we have:
[tex]E = z_y \times \frac{6}{\sqrt {10}}[/tex]
The quantile at 95% confidence interval is 2.262
So, the equation becomes
[tex]E = 2.262 \times \frac{6}{\sqrt {10}}[/tex]
Hence, the equation that represents the margin of error is: [tex]E = 2.262 \times \frac{6}{\sqrt {10}}[/tex]

This is the only possible correct answer because the other three all show the final price as 0.90x, which is correct since the price is the normal one minus 10 percent. C is incorrect because it suggests the normal price has a 10% tax, or extra value on it.
