A company's cereal boxes advertise that 9.65 ounces of cereal are contained in each box. In fact, the amount of cereal in a randomly selected box follows a normal distribution with mean LaTeX: \muμ = 9.70 ounces and standard deviation LaTeX: \sigmaσ = 0.03 ounces. A quality control worker selects a random sample of 5 cereal boxes. What is the standard deviation LaTeX: \sigma_{\frac{ }{x}}σ x(in ounces) of this sampling distribution?
Answer:
The standard deviation of the sampling distribution σₓ = 0.013
Step-by-step explanation:
Explanation:-
Mean of the Population μ = 9.70 ounces
Standard deviation of the Population σ = 0.03 ounces
Given size of random sample 'n' =5
The standard deviation of the sampling distribution
σₓ = σ/√n
[tex]S.D = \frac{0.03}{\sqrt{5} } = 0.013[/tex]

how do raise a power to a power
Answer: The exponent "product rule" tells us that, when multiplying two powers that have the same base, you can add the exponents. Adding the exponents is just a short cut! The "power rule" tells us that to raise a power to a power, just multiply the exponents.
Step-by-step explanation:
A group of friends were working on a student film. They spent all their budget on props and costumes. They spent $243 on props, and 55% of the total budget on costumes. What was the total budget for their student film?
Answer:
The total budget for their student film was $540
Step-by-step explanation:
The total percentage of any quantity is 100%
∵ A group of friends was working on a student film
∵ They spent all their budget on props and costumes
∴ The total budget of the props and costumes = 100%
∵ They spent $243 on props
∵ They spent 55% of the total budget on costumes
→ Find the percentage of the props
∴ The percentage of the props = 100% - 55%
∴ The percentage of the props of the total budget = 45%
→ That means 45% of the total budget = 243
∵ 45% × total budget = 243
→ Change the percent to a number by divide it by 100
∵ 45% = 45 ÷ 100 = 0.45
∴ 0.45 × total budget = 243
→ Divide both sides by 0.45
∴ The total budget = 540
∴ The total budget for their student film was $540

Graph y−5=−2/3(x+9) using the point and slope given in the equation.
Use the line tool and select two points on the line.
(There is a graph with all 4 quadrants and the values go up to 10 for both x and y)
Answer:
Well, I don't know how to graph it for you, but the slope is -2/3 and the point is (-9, 5). So, when you graph it, from the point (-9, 5), you can go 3 units to the right and 2 units down.

Answer:
Ms. Cortez earns 500 dollars for working 30 hours. It's the last choice.
Step-by-step explanation:
You just have to substitute 30 into the equation in place of x, since x represents hours.
f(30) = 50 + 15(30)
f(30) = 50 + 450
f(30 = 500

Item 4 Question 1 Determine of which lines, if any, are parallel or perpendicular. Explain. Line a passes through (−2, 1) and (0, 3) . Line b passes through (4, 1) and (6, 4) . Line c passes through (1, 3) and (4, 1) .
Answer:
Line b and line c are perpendicular.
Step-by-step explanation:
In order to find if the lines are parallel, perpendicular or neither, their slopes have to be found.
Slope is denoted by m and is calculated as:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Here (x1,y1) and (x2,y2) are the coordinates of the point through which the line passes.
Let m1 be the slope of line a
and line a passes through (−2, 1) and (0, 3)
[tex]m_1 = \frac{3-1}{0+2} = \frac{2}{2} = 1[/tex]
Let m2 be the slope of line b which passes through (4, 1) and (6, 4)
[tex]m_2 = \frac{4-1}{6-4} = \frac{3}{2}[/tex]
Let m3 be the slope of line c which passes through (1, 3) and (4, 1)
[tex]m_3 = \frac{1-3}{4-1} = \frac{-2}{3}[/tex]
When two lines are parallel, their slopes are equal.
When two lines are parallel, the product of their slope is -1
None of the slopes are equal to each other so none of the lines are parallel
And
[tex]m2.m3\\= \frac{3}{2} * -\frac{2}{3}\\= -1[/tex]
Hence,
Line b and line c are perpendicular.

War Eagle spied 1428 antelope and wildebeests grazing on the savannah. If the ratio of antelope to wildebeests was 9 to 5, how many antelope were there? (Answer is 918 but idk how to solve it.....)
Answer:
9:5 = 1428:x
ratios can also be written as fractions, so
9/5 = 1428/x
solve for x
9/5 × x = 1428
x = 1428 / (9/5)
x = 918
The value of the function g(x) is −2 when x=−5 and is 5.7 when x=6. What is the equation for the function g(x)?(1 point)
Given:
The value of the function g(x) is −2 when x=−5 and is 5.7 when x=6.
To find:
The equation of the function.
Solution:
The value of the function g(x) is −2 when x=−5. It means the graph of function passes through (-5,-2).
The value of the function g(x) is 5.7 when x=6. It means the graph of function passes through (6,5.7).
The equation of function g(x) that passes through (-5,-2) and (6,5.7) is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-(-2)=\dfrac{5.7-(-2)}{6-(-5)}(x-(-5))[/tex]
[tex]y+2=\dfrac{5.7+2}{6+5}(x+5)[/tex]
[tex]y+2=\dfrac{7.7}{11}(x+5)[/tex]
[tex]y+2=0.7(x+5)[/tex]
[tex]y+2=0.7x+3.5[/tex]
Subtract 2 from both sides.
[tex]y=0.7x+3.5-2[/tex]
[tex]y=0.7x+1.5[/tex]
Therefore, the equation of function g(x) is [tex]y=0.7x+1.5[/tex].

Consider the following vectors in polar form.
|u| = 2 at ∠0°
|v| = 4 at ∠45°
What is the magnitude of vector w, if w = u – v?
|w| = 2.77
|w| = 2.95
|w| = 3.58
|w| = 5.60
Answer:
B 2.95
Step-by-step explanation:
The magnitude of w is |w| = 2.95 , Option B is the correct answer.
What is a Vector ?Any object that has both magnitude and direction is called a Vector.
It is given that
|u| = 2 at 0 degree
|v| = 4 at 45 degree
The magnitude of the vector w = | u -v| = ?
The resultant angle will be 45 degree
By applying Cosine law
w = | u -v| = [tex]\rm \sqrt { u^2 + v^2 - 2*u*v*cos \theta}[/tex]
w = | u -v| = [tex]\rm \sqrt { 2^2 + 4^2 - 2*2*4*cos 45^o}[/tex]
w = 2.947 = 2.95
Therefore the magnitude of w is |w| = 2.95 , Option B is the correct answer.
