The probability of getting a soda at the movie theater is 70%. What is the probability that the next three guests in the movie theater will get a soda
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%.
What is probability?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%.

Write an equation for a line that passes through (1,-4) and (3,-5)
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)

what is w + 4 1/4 = 13 19/20
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

arithmetic sequence :
-92, -85, -78, -71, .
363
Step-by-step explanationT1= a= -92
T2= -85
common difference d = T2-T1
d = -85 -(-92)
= -85 +92
= 7
Tn = a + (n-1)d
T66 = -92 + (66-1)7
= -92 + (65)7
= -92 + 455

Step-by-step explanation:
x= -5y + 36
5x + 5y = 0
The substitution method. Also please help me I’m so confused
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
