Answer:

The standard error of the mean (SE) is of 0.326lb.

Step-by-step explanation:

The standard error of the mean is given by the following formula:

SE = \frac{s}{\sqrt{n}}

In which s is the standard deviation of the sample and n is the size of the sample.

In this problem, we have that:

s = 4.3, n = 174

Then

SE = \frac{s}{\sqrt{n}} = \frac{4.3}{\sqrt{174}} = 0.326

The standard error of the mean (SE) is of 0.326lb.

Q(3x)=12x+2 then what is Q(x-2)
Mandarinka [93]

Answer:

it's ax+b form answer is Q(x-2)=4x-6

Step-by-step explanation:

ax+b=Q(x),Q(x-2)=a(x-2)+2

Q(3x)=a(3x)+b=12x+2, 3a=12 =>a=4,b=2

the original q of x is 4x+2

Q of x-2 =4(x-2)+2=4x-8+2=4x-6

Use the original price and the markup to find the retail price.
Ber [7]

Answer:

$45.15

Step-by-step explanation:

When you are dealing with questions with percents in them—like this one—you have to turn the percent into a decimal. To make 7.5% into a decimal, you move the decimal point 2 spaces to the left. So, 7.5% is also 0.075.

Now, we have to use this formula for these types of questions:

x + x(y)= the price with tax (or markup)

So, we can substitute the variables.

42+42(0.075)=the retail price

42(0.075)=3.15

42+3.15=45.15

So, the retail price will be $45.15
