Answer: (1500.66,1599.34)

Step-by-step explanation:

Confidence interval for population mean:

[tex]\overline{x}\pm z^*\dfrac{\sigma}{\sqrt{n}}[/tex]

,where [tex]\overline{x}[/tex] = Sample mean , n= Sample size, z* = critical two tailed z-value , [tex]\sigma[/tex] = population standard deviation.

As per given , we have

n= 16

[tex]\sigma = 154[/tex] square feet

[tex]\overline{x}= 1550[/tex] square feet

[tex]\alpha= 1-0.80 = 0.20[/tex]

Critical z-value = [tex]z_{\alpha/2}=z_{0.2/2}=z_{0.1}=1.2815[/tex]

Confidence interval for population mean:

[tex]1550\pm (1.2815)\dfrac{154}{\sqrt{16}}\\\\ = 1550\pm (1.2815)\dfrac{154}{4}\\\\= 1550\pm 49.33775\\\\ =(1550-49.33775,\ 1550+49.33775)\\\\\approx (1500.66,\ 1599.34)[/tex]

Required confidence interval:  (1500.66,1599.34)

Answer:

The cost function for [tex]C(x) = 0.06\cdot e^{0.08\cdot x}[/tex] is [tex]c(x) = 0.75\cdot e^{0.08\cdot x}+10[/tex].

Step-by-step explanation:

The marginal cost function ([tex]C(x)[/tex]) is the derivative of the cost function ([tex]c(x)[/tex]), then, we should integrate the marginal cost function to find the resulting expression. That is:

[tex]c(x) = \int {C(x)} \, dx + C_{f}[/tex]

Where:

[tex]C_{f}[/tex] - Fixed costs, measured in US dollars.

If we know that [tex]C(x) = 0.06\cdot e^{0.08\cdot x}[/tex] and [tex]C_{f} = \$\,10[/tex], then:

[tex]c(x) = 0.06\int {e^{0.08\cdot x}} \, dx + 10[/tex]

[tex]c(x) = 0.75\cdot e^{0.08\cdot x}+10[/tex]

The cost function for [tex]C(x) = 0.06\cdot e^{0.08\cdot x}[/tex] is [tex]c(x) = 0.75\cdot e^{0.08\cdot x}+10[/tex].

Answer:

f(x)=2x^2-3x+1

the graph of the function is attached with the answer

As we can see that equation is quadratic and its graph is a parabola facing upward.

As we can see it passes the Vertical line test

As it passes the Vertical line test , So it is a function

And two values of x has one value of y

So it is a many to one function.

Answer:

Mean = 11.3 grams

Standard Deviation = 3.5 grams

Step-by-step explanation:

Mean is affected by change of origin but standard deviation is not affected. Hence the scale weighed items 1.5 grams affect only the mean not standard deviation. Hence, the mean for new food item is 12.8 - 1.5 = 11.3 grams as weight gain by 1.5 gram due to wrong calibration and the standard deviation remains the same as 3.5 grams.

Answer:

[tex]x=5,y=4[/tex]

Step-by-step explanation:

[tex]2x-3y=-2[/tex]

Add 3y to both sides:

[tex]2x-3y+3y=-2+3y[/tex]

[tex]2x=-2+3y[/tex]

Divide both sides by 2:

[tex]\frac{2x}{2}=-\frac{2+3y}{2}[/tex]

[tex]x=\frac{-2+3y}{2}[/tex]

Substitute this into the second equation:

[tex]4* \frac{-2+3y}{2}+y=24[/tex]

[tex]2\left(3y-2\right)+y=24[/tex]

[tex]7y-4=24[/tex]

Add 4 to both sides:

[tex]7y-4+4=24+4[/tex]

[tex]7y=28[/tex]

Divide both sides by 7:

[tex]\frac{7y}{7}=\frac{28}{7}[/tex]

[tex]y=4[/tex]

We know that [tex]x=\frac{-2+3y}{2}[/tex]

Thus, [tex]x=\frac{-2+3* \:4}{2}[/tex]

[tex]x=\frac{10}{2}[/tex]

[tex]x=5[/tex]

The volume of the rectangular prism given the information in the question is 10 feet³.

A rectangular prism is a three-dimensional shape. It also known as a cuboid. It has six faces, 12 sides and 6 vertices

Volume = length x width x height

Volume = 1/3 (number of squares that make up the length x number of squares that make up the width x number of squares that make up the height)

1/3 (5 x 2 x 3) = 10 feet^3

Answer:

-3

Step-by-step explanation:

You would find what the answer to (5•3) is then subtract that answer with 18. So it would be 15-18=-3

Answer:

The answer is -3

Step-by-step explanation:

The answer is -3 because of the order of operations PEMDAS (parenthesis, exponent, multiplication/division, addition/subtraction)

Therefore, you would multiply the two numbers inside the parenthesis first, which would give you 15-18, and from there you can subtract 18 from 15 which would give you -3.

Answer:

E=180-145=35

y = 1 / 2x

Answer:

1/2

Step-by-step explanation:

Answer: 1/2

Step-by-step explanation:

First convert the equation into slope-intercept form.

-10 + x -2y = 0

+10               +10

 x - 2y = 10

-x             -x

-2y = 10 - x   Divide both sides by -2

y = 1/2x - 5

In this case the slope is 1/2  and the slopes parallel lines are the same but they must have different y intercepts.  Meaning that the slope of the other line will be 1/2.
