A beverage distributor has a facility that bottles beer. Beer bottles are supposed to be filled to 12 oz but there are slight variations. As part of quality control, they randomly sample bottles of beer and measure how many ounces they contain. In the most recent sample, the found an average fill of 12.01 oz with a standard deviation of 0.89.
If one of the bottles of sampled beer was filled to 10.98 oz, what is its associated zscore?
Is this bottle an outlier?

Answers

The associated z score for filling to 10.98 oz. is -1.16.

Z score

The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

z = (x - μ) / σ

where x is the raw score, μ is the mean and σ is the standard deviation.

Given that μ = 12.01, σ = 0.89, hence:

For x = 10.98:

z = (10.98 - 12.01)/0.89 = -1.16

The associated z score for filling to 10.98 oz. is -1.16.

Area of a trapezoid is calculated by the following formula:

(a+b)/2 * h (a: base, b: base, h:height)

(6+12)/2 * 4 = 36 the area is 36 m^2

The perimeter is calculated by adding all side lengths or multiplying the sum of non-parallel sides by 2

Only the measure of AB=AC is missing to find it we can use the method in attached photo

Sam claims that when he completes the transformation f(x) +3, the
parent function would move three units to the left.
Part A: Do you agree or disagree? Why or why not?
Part B: What misconception do you think Sam needs to clear up?

Answers

A) Disagree, The transformation f(x) + 3 represents moving the graph vertically up by 3 units.

B) A vertical transformation involves changing the y-coordinate of the graph, while a horizontal transformation involves changing the x-coordinate of the graph.

What is Translation?

A transformation that occurs when a figure is moved from one location to another location without changing its size or shape is called translation.

Since, We know that;

The transformation f(x) + 3 represents moving the graph vertically up by 3 units.

Therefore, the parent function would not move three units to the left.

It seems that Sam has a misconception about vertical and horizontal transformations.

For clarify, a vertical transformation involves changing the y-coordinate of the graph, while a horizontal transformation involves changing the x-coordinate of the graph.

Thus, We get;

A) Disagree, The transformation f(x) + 3 represents moving the graph vertically up by 3 units.

B) A vertical transformation involves changing the y-coordinate of the graph, while a horizontal transformation involves changing the x-coordinate of the graph.

Matt and Anna Killian are frequent flors on Fast-n-Go Airlines, They often fly between two cities that are a distance of 800 miles apart. On one particular trip, they
flew into the wind and the trip took 2.5 hours. The return trip with the wind behind them, only took about 2 hours. Find the speed of the wind and the speed of the
plane in still air
Pls help

Answers

Answer:

The speed of the wind is 40mph, the speed of the plane in still air is 360mph

Step-by-step explanation:

distance = speed * time

Both legs of the trip are 800 miles, let 'x' represent the speed of the plane in still air and 'w' represent the speed of the wind, then 'x+w' represents the speed with the wind and 'x-w' represents the speed into the wind

800 = (x-w)2.5

800 = (x+w)2

Rewrite equations:

800=−2.5w+2.5x;800=2w+2x

Steps: Solve 800=−2.5w+2.5x for w:

800=−2.5w+2.5x

800+2.5w=−2.5w+2.5x+2.5w(Add 2.5w to both sides)

2.5w+800=2.5x

2.5w+800+−800=2.5x+−800(Add -800 to both sides)

2.5w=2.5x−800

2.5w/2.5 = 2.5x - 800 / 2.5 (Divide both sides by 2.5)

w=x−320

Step: Substitute x−320 for w in 800=2w+2x:

800=2w+2x

800=2(x−320)+2x

800=4x−640(Simplify both sides of the equation)

800+−4x=4x−640+−4x(Add -4x to both sides)

−4x+800=−640

−4x+800+−800=−640+−800(Add -800 to both sides)

−4x=−1440

-4x/-4 = -1440/-4 (Divide both sides by -4)

x=360

Step: Substitute 360 for x in w=x−320:

w=x−320

w=360−320

w=40(Simplify both sides of the equation)

solving this system we have:

w=40

x=360

Therefore, the speed of the wind is 40mph, the speed of the plain in still air is 360mph

Explain to your guardian how you would solve the below problem
step by step. Solve the system y = 2x + 6 and 3y = 6x + 18 by using graph paper or graphing technology.
What is the solution to the system? Feel free to submit graphs.

Answers

Answer:

infinite solutions

Step-by-step explanation:

y = 2x + 6

when x = 0,  y = (2 x 0) + 6 = 6  ⇒  (0, 6)

when y = 0,  0 = 2x + 6  ⇒  x = 3  ⇒ (3, 0)

Plot the two points and draw a line through them

3y = 6x + 18

divide everything by 3  ⇒  y = 2x + 6

Therefore, y = 2x + 6 equals 3y = 6x + 18

So the lines overlap (produce the same graph)

Therefore, the system will have infinite solutions

Hi there!

This is the sine ratio:

[tex]\sin\theta=\displaystyle\frac{opposite}{hypotenuse}[/tex] where "opposite" is the side opposite the angle, "hypotenuse" is the hypotenuse of the right triangle and theta is the angle.

To find sin B, we must identify which sides of the triangle are the opposite side and the hypotenuse.

The side opposite to angle B would be b.

The hypotenuse is the side opposite the right angle, and that would be c.

Step-by-step explanation:

1. f(x) + g(x) = x - 11.

2. f(x) - g(x) = - 3x + 9.

3. f.g = 30x² + 28x - 6, all real numbers.

4. f/g = x + 4, all real numbers, x ≠ 4.

5. It doesn't matter which discount is applied first the result is the same.

What is a composite function?

When the output of one function is given to the input of another function they are called composite functions.In (fog)x which is [f{g(x)}] here the out of the function g(x) is the input of the function f(x).

1. f(x) = - 5x - 4 and g(x) = 6x - 7.

Therefore, f(x) + g(x) = - 5x - 4 + 6x - 7.

f(x) + g(x) = x - 11.

2. f(x) = 3x + 2 and g(x) = 6x - 7.

Therefore, f(x) - g(x) = 3x + 2 - (6x - 7).

f(x) - g(x) = 3x + 2 - 6x + 7.

f(x) - g(x) = - 3x + 9.

3. f(x) = 5x + 3 and g(x) = 6x - 2.

Therefore, f.g = f(x)×g(x) = f(x).g(x).

f.g = (-5x + 3)(6x - 2).

f.g = -30x² + 10x + 18x - 6.

f.g = 30x² + 28x - 6.

The domain is all real numbers no restrictions.

4. f(x) = x² - 16 and g(x) = x + 4.

Therefore, f/g = f(x)/g(x).

f/g = (x² - 16)/(x + 4)(x - 4).

f/g = (x + 4)(x - 4)/(x - 4).

f/g = x + 4.

The domain of f/g is all real numbers except x ≠ 4.

5. Let, The original amount be 100.

25% off on 100 is 75 and 10% off again is 75 - 7.5 = 67.5.

Again, 10% off on 100 is 90 and 25% off on 90 is 90×0.75 = 67.5.

So, Both way is the same.

Step-by-step explanation:

x + y = 14 --> x = 14 - y

$0.10x + $0.25y = $2.00, or 10x + 25y = 200

- we can plug this value for x from the first equation into the second:

10(14 - y) + 25y = 200

140 - 10y + 25y = 200

140 + 15y = 200

15y = 60

y = 4 --> 4 quarters ($0.25 x 4 = $1.00)
