Answer:

$3 for the small drinks and $4 for the large popcorn

Step-by-step explanation:

so we know that 2 popcorns and 4 small drinks give us $20 and 2 popcorns and 2 drinks gives us 14. so $6 was taken away because of two drinks and 6÷2 equals 3 therefore $3 is how much a small drink costs. after taking away another 6 from 14 because we found the costs of drinks we get $8 for two popcorns and 8÷2 is 4 so a large popcorn costs $4

Answer:

The large popcorn bucket cost $4 and the small drink cost $3.

Step-by-step explanation:

The formula for Margin of Error =

Margin of Error = z × standard deviation/√n

Margin of Error= ± 6

z = z score of 95% Confidence Interval is 1.96

s = 20

n = sample size

±6 = 1.96 × 20/√n

Cross Multiply

±6 × √n = 1.96 × 20

±6 × √n = 39.2

Divide both sides by ±7

√n = 39.2/±6

√n = 6.5333333333

Square both sides

n = 6.5333333333²

n= 42.684444444

Rounding up to the nearest integer = 43

Alg I

Step-by-step explanation:

The meaning of f(2) is x = 2. The question is asking us to find the y-value when x = 2.

According to the graph, when x = 2, y is somewhere between 8 and 10. The graph looks like it intersects right in the middle of those 2, so the y-value when x = 2 would be 9.

Therefore, f(2) = 9.

Answer:

Step-by-step explanation:

9 is the correct answer

Answer:

B

Step-by-step explanation:

The solutions to a quadratic equation is whenever the graph crosses the x-axis. The solutions are also known as the roots or zeros of the quadratic.

Our quadratic crosses the x-axis at -3 and 1. So, at those two points, f(x) is 0. Namely, we have the two points (-3, 0) and (1, 0).

So, our two solutions are -3 and 1.

Hence, our answer is B.

Answer:

I think it would be B

Step-by-step explanation:

If f(x) is 0, that means the value of x would not change at all. and since its only on the x-axis and neither numbers are used for the y-axis, the solutions would most likely be -3 and 1.

Answer:

1) x = 1  ,  y = 2

2) x=3, y=-2

3) x=3, y=-4

4) x=0, y=-3

Answer:

The following display from a TI-84 Plus calculator presents a 99% confidence interval for a proportion.Fill in the blanks:

We are ____99%____ confident that the population mean is between ___0.385631____ and ___0.780609____.

c) 99%, 0.385631, 0.780609

Step-by-step explanation:

This is the only correct option, given the relevant population mean range.  Option B is not correct as the population mean cannot range between 0 and 0.583120 as given by the option.  Options 'a' and 'd' are not relevant to the question because they have 1% confidence level, instead of the stated 99% confidence level.

Answer:

It would take 5 years for the car to have a value of less than $25,000

Step-by-step explanation:

Exponential Decaying Model

The exponential function is often used to model natural decaying processes, where the change is proportional to the actual quantity.

We have the initial value of a car is $40,000. Each year it depreciates by 10%.

Thus the first year its value is 90% of the initial value:

V1 = 90 * $40,000 / 100 = $36,000

By the second year its value is 90% of $36,000:

V2 = 90 * $36,000 / 100 = $32,400

Note the value for a year n is the original value multiplied by 90% (or 0.9) to the power of n:

[tex]Vn = $40,000 \cdot 0.9^n[/tex]

To find the number of years needed to have a value of less than $25,000, we solve the equation:

[tex]40,000 \cdot 0.9^n = 25,000[/tex]

Dividing by 40,000:

[tex]0.9^n = 25,000/40,000 = 0.625[/tex]

Taking logarithms:

[tex]n\log 0.9=\log 0.625[/tex]

[tex]n=\log 0.625 / \log 0.9[/tex]

n =4.5

We'll round up to n = 5

It would take 5 years for the car to have a value of less than $25,000

Answer:

f(3) = 3

Step-by-step explanation:

f(x) = (1/7)(7x)

f(3) = (1/7)(7×3)

f(3) = (1/7)(21)

f(3) = 3

Answer:

Step-by-step explanation:

go from one point to the other. From the left point to the right point you are running across (to the right) three times. Then you are ¨rising¨ (going down) once. going to the right is positive. If you are going down its negative. Vise versa. The formula is Rise/Run. your answer would be -1/3. the one is negative because it went down.Then divide it and you have -0.333. I hope I helped!

Answer:

x = 4

Step-by-step explanation:

3x÷2=6

Multiply both sides by 2.

3x = 12

Divide by 3.

x = 4

Answer:

x=4

Step-by-step explanation:

To solve [tex]\frac{3x}{2}[/tex]=6 you need to isolate the variable. To do this you need to do the opposite operation of all of the constants.

First, multiply both sides by 2,

[tex]\frac{3x}{2}[/tex]*2=6*2

3x=12

Then divide both sides by 3,

3x/3=12/3

x=4

Answer:

7) y = -2

8) x = 4

Step-by-step explanation:

Any straight horizontal/vertical line you find will be x= or y=. The vertical lines are always x= because they only touch the x axis. It's the opposite for horizontal lines. For example, on number 7, the line touches -2 on the y axis. That's why it's "y=-2". Same goes for 8. the line only touches 4.

I hope this helped and wasn't confusing!

Answer:

4/9

Step-by-step explanation:

Answer: 10,8,5 are all right angles (90 degrees) 7,6,9,2 are all acute angles and are 42 degrees

1 and 3 are obtuse angles and they are 117 degrees.

Step-by-step explanation:

Answer:

Being proportional between two entities, refers to the 'Constant of Proportionality' that would be fixed between them which establishes a relationship between them when multiplied or divided.

If we considered it on a graph, the 'Constant Of Proportionality' may take any real values between the coordinate pairs x and y [x,y]. As even 0 is a real number, it will surely be a constant of proportionality when multiplied since its product would result in itself (0). Hence, both x and y turns 0.

As the coordinates of the origin are always (0,0), the graph  (Or the slope) would surely pass through the origin.

Example :

If we consider a graph such that x=y.

And if we multiply or divide any real number (a) between them.

ax=ay

As a is a variable, and can take the value of 0, the graph can pass through the origin as x and y nullify becoming the coordinates of the origin.
