Then divide by how many tips there are

[350 ÷ 6]

therefore your answer is $58.33

The probability that the next three guests in the movie theater will get a soda, when the probability of getting a soda at the movie theater is 70% is 0.343 or 34.3%.

Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.

The probability of getting a soda at the movie theater is 70%.

[tex]P=70\%\\P=\dfrac{70}{100}\\P=0.7[/tex]

By the chain rule, the probability of getting the soda to the next 3 guest is equal to the cube of the probability of getting a soda at the movie theater.

Thus, the probability that the next three guests in the movie theater will get a soda is,

[tex]P^3=0.7^3\\P^3=0.343[/tex]

Thus,the probability that the next three guests in the movie theater will get a soda, when the probability of getting a soda at the movie theater is 70% is 0.343 or 34.3%.

Answer:

w = 9 7/10

Step-by-step explanation:

w + 4 1/4 = 13 19/20

Subtract 4 1/4 from each side

w = 13 19/20 - 4 1/4

Get a common denominator of 20

w = 13 19/ 20  - 4 1/4*5/5

w = 13 19/ 20  - 4 5/20

w = 9 14/20

We can simplify

w = 9 7/10

Rewrite the fractions to have the same denominator:

1/4 can be rewritten as 5/20

now you have w + 4 5/20 = 13 19/20

Solve for w by subtracting 4 5/20 from both sides:

W = 9 14/20 which can be rewritten as 9 7/10

answer: 9 7/10

Given the method given to calculate an outlier, the method does not identify 7.5 miles as an outlier.

An outlier is either very much larger or smaller than the rest of the data in the dataset.  In this dataset: 1, 2, 1000. 1000 is an outlier.

Outlier = 1.5 x interquartile range

Answer:

y = -3/4x - 1/2

Step-by-step explanation:

Given:

Point 1: (1, -4)

Point 2: (3, -5)

Find:

The equation for the line that passes through Point 1 & Point 2

Solution:

y = mx + b

Will be the equation to arrive to at the very end, but we need m & b, the slope and the y-intercept

m = ( y2 - y1 ) / ( x2 - x1 ) = ( -5 - (-4) ) / ( 3 - 1 ) = -1 / 2

∴ m = - 1/2

Using either P1 or P2, plug in one of their respective x- and y-values into:

y = -1/2 x + b

I'll do (3, -5):

-5 = -1/2 ( 3 ) + b

-2 = -3/2 + b

-4 = -3 + 2b

-1 = 2b

∴ b = -1/2

∴ y = -3/4x - 1/2 is the equation of the line that passes thru both points (-5, 4) and (3, -2)

Answer:

x = -9
y = 9

Step-by-step explanation:

If we know that x  =  -5y + 36
The second line says that
5x + 5y = 0
We can substiute the value of x from the first line into the second line.

So it becomes
5 ( -5y+36) + 5y = 0
Distribute the 5 over the parentheses
-25y + 180 +5y = 0
Then we can add things that are alike; so that means we can add the y values
-20y + 180 = 0
Then add 20y to both sides of the equation
180 = 20y
Then you divide by 20.
You get 9 = y!
Now that you have the value of y, you can put it back into the intial question.
5x+5y = 0
5x + 5(9) = 0
5x + 45 = 0
5x = -45
x = -9

Answer:

x=-9 y=9

Step-by-step explanation:

Substitute x:

5(-5y+36)+5y=0

Use Distributive property

-25y+180+5y=0

Add Like terms

-20y+180=0

Subtract 180 from both sides

-20y=-180

divide -20 from both sides

y=9

Solve for x by substituting the value of y into the equation x= -5y + 36

to get x=-9
