What is the volume of the rectangular prism?
1/3ft
The volume of the rectangular prism given the information in the question is 10 feet³.
What is the volume of the rectangular prism?
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

Step-by-step explanation:
A student was performing an experiment that compared a new protein food to the old food for goldfish. He found the mean weight gain for the new food to be 12.8 grams with a standard deviation of 3.5 grams. Later he realized that the scale was out of calibration by 1.5 grams (meaning that the scale weighted items 1.5 grams too much). What should the mean and standard deviation be for the new food
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.

2x – 3y = -2
4x + y = 24
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]

What is (5•3) - 18 and can u explain y
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.

Find the slope of a parallel line -10+x-2y=0
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.

Find the cost function for the marginal cost function. C(x) =0.06 e 0.08x; fixed cost is $10 C(x)=_______
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].

Find the midpoint and the distance between these 2 points. (-4,8) and (6,-2)
Answer:
Midpoint = (1,3)
Distance = 10√2
Step-by-step explanation:
Midpoint
[tex]Midpoint = \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)\\\\\left(x_1,\:y_1\right)=\left(-4,\:8\right),\:\left(x_2,\:y_2\right)=\left(6,\:-2\right)\\\\=\left(\frac{6-4}{2},\:\frac{-2+8}{2}\right)\\\\=(\frac{2}{2} , \frac{6}{2} )\\\\Simplify\\=\left(1,\:3\right)[/tex]
Distance
[tex]Distance = \sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}\\\\(-4,8)=(x_1,y_1)\\(6,-2)=(x_2,y_2)\\\\d=\sqrt{\left(6-\left(-4\right)\right)^2+\left(-2-8\right)^2}\\\\d = \sqrt{(6+4)^2+(-2-8)^2}\\ \\d = \sqrt{(10)^2 +(-10)^2}\\ \\d = \sqrt{100+100} \\\\d = \sqrt{200}\\ \\d = 10\sqrt{2}[/tex]

The number of square feet per house is normally distributed with a population standard deviation of 154 square feet and an unknown population mean. If a random sample of 16 houses is taken and results in a sample mean of 1550 square feet, find a 80% confidence interval for the population mean. Round your answer to TWO decimal places.
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)
