In a movie theater, 2 boys and 3 girls are randomly seated together in a row. What is the probability that the 2 boys are seated next to each other
Answer: 2/5
Step-by-step explanation: 2/5 is the answer bozo
The probability that the 2 boys are seated next to each other will be P(A) = 0.16.
What is a probability? Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.Given is that in a movie theater, 2 boys and 3 girls are randomly seated together in a row.
The total number of ways in which all of them can be seated are -
n{S} = (2 + 3) x (2 + 3) = 5 x 5 = 25
n{S} = 25
The total number of ways in which two boys can be seated together are -
n{A} = 4
So, the probability that the 2 boys are seated next to each other will be -
P(A) = n(A)/n(S)
P(A) = 4/25
P(A) = 0.16
Therefore, the probability that the 2 boys are seated next to each other will be P(A) = 0.16.

What is the slope of this line?
Enter your answer as a whole number or a fraction in simplest form in the FAST PLS
Answer:
1/4
Step-by-step explanation:
Answer:
1/4
Step-by-step explanation:
To find the slope of a graph, use rise/run or change of y over change of x.
Just from looking at the graph, the slope has to be positive as the line is going up!
Start from the point that intersects with the line and graph. Then find another point that also intersects with the line and graph as well.
So for this graph, I am using the two points to the left.
I start from the bottom point and go up 1. Then I go to the right 4 times until I get to the second point.
Thus, the slope is 1/4!

Step-by-step explanation:
it’s the slope
The slope of the line is 4.
\What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.2The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
A line is perpendicular to the line y = 4x - 3.
y = 4x - 3 is in the form of y = mx + c
So,
m = 4.

9. John bought a case of 12 boxes of Macaroni and Cheese for $11.99. When he got home, he noticed that the same case of Macaroni and Cheese was on sale at a different location for $10.49. How much would he have saved per box of Macaroni had he purchased it at the other location? Show work.
Answer:
12.5 cents per box
Step-by-step explanation:
First, find the price difference of the cases.
11.99 - 10.49 = $1.50
We want to find the money saved per box so divide $1.50 by 12.
1.50/12 = 12.5 cents

What is the percentage?The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.
Dennis made an extra $245.00 for selling furniture.
Let the cost of the furniture be x.
Let the total value of the furniture be x + 245.
The extra $245.00 was 7% of the total value of the furniture he sold.
0.07(x + 245) = 245
x+ 245 = 3500
x = 3255
Then the total value of the furniture is (3,255 + 245 =) $3,500.

subtract 2ydistribute 5add 2ydivide by 25Step-by-step explanation:
[There's a lot to read here. If you read it, maybe you'll have a better understanding.]
This is asking you the first step required to solve each of the equations.
The general process of solving an equation involves performing operations that result in the variable of interest being on one side of the equal sign (by itself), and everything else being on the other side. When variable and constant terms are mixed, we generally want to remove the variable term.
The underlying rule for all of this is "whatever is done to one side of the equation must also be done to the other side." The exceptions are simplification and substitution.
"Inverse" operations are of use in this process. That is why you are taught about the "additive inverse" (negative) of a number, and the "multiplicative inverse" (reciprocal) of a number. Adding the additive inverse results in the additive identity element (0). Similarly, multiplying by the multiplicative inverse results in the multiplicative identity element (1). Adding 0 or multiplying by 1 leaves only the original value.
__
With this in mind, we can look at the given equations to see what is needed to solve them.
2 +2y = y
We see that the left side of the equation has both a constant term and a variable term. To remove the variable term we add its additive inverse: (-2y). Adding a negative value is the same as subtracting a positive value. That is, we can describe what we want to do as "subtract 2y from both sides".
When we do that, the result is ...
2 +2y -2y = y -2y . . . . . here, we show the subtraction
2 = -y . . . . . . . . . . . . . and this is the result of simplifying that.
Notice the y term is now on one side of the equal sign and the constant is on the other side. We are one step closer to the solution, which is the whole point.
__
5(y -4) = 2y
This equation has parentheses. It often works well as a first step to eliminate the parentheses, generally using the distributive property. That is, we "distribute 5".
When we do that, the result is ...
5(y) -5(4) = 2y . . . . . . . . here, we show the distribution
5y -20 = 2y . . . . . . . and this is the result of simplifying that
This puts us one step closer to the solution, which is the whole point.
__
5y = 10 -2y
Here, the unwanted variable term is -2y on the right side of the equation. To remove it, we add 2y to both sides.
When we do that, the result is ...
5y +2y = 10 -2y +2y . . . . . . . showing the addition of 2y
7y = 10 . . . . . . . . . . . . . . . simplified
This puts us one step closer to the solution.
__
5 = 25y
This equation has the variable term and the constant term already separated. However, there is a coefficient on the variable term that is not equal to 1. We want to make that coefficient be 1. To do that, we multiply it by its multiplicative inverse: 1/25. That is, we divide both sides by 25.
When we do that, the result is ...
5/25 = 25y/25 . . . . . . showing division by 25
1/5 = y . . . . . . . . . simplified (and the fraction reduced)
This gives us the solution. There are no more steps required.

Answer:
77%, yes pass, at least 16
Step-by-step explanation:
so 17/22 is 0.77, convert to percentage is 77%
77% is above 70% so you passed
if you guess and check, 15/22 is 68%. since thats just a bit lower than 70%, u need at least 16 questions to pass
yw in advance :))

a) 77% b) Yes c) 16
Step-by-step explanation:
17 out of 22 questions correct is set up as
17/22= .7727
round this number down and take it from decimal form to percentage.
.77 x 100 = 77%
You scored a 77% and you did score enough to pass.
The minimum number correct to still be able to pass is 16.

A submarine dives 650 feet every 5 minutes and 5,200 feet every 40 minutes.
Answer:
Step-by-step explanation:
Answer:
feet per minute
300/2 = 6750/45 = 150 ft/minute
Since submarines dive quickly, and need to be able
to respond rapidly to sudden changes in conditions,
it is more reasonable to use feet per minute. If we work
in feet per hour at this speed we would need to convert
the data back to feet per minute in order to ensure we
don't dive too deep.
Dn = Dn-1 + 150m
where Dn is depth, Dn-1 is previous depth,
and m is number of minutes diving.

Write an equation of the line passing through the given points. (4.-31) and (-2,5)
Step-by-step explanation:
the most common form of line equation is
y = ax + b
a is the slope of the line. it is expressed as the ratio
y coordinate change / x coordinate change
when going from one point to the other.
b is the y-intercept (the y value when x = 0).
once we have the slope, we get b by using the coordinates of one of the given points as x and y in the equation and since for b.
for slope a :
x changes by -6 (from 4 to -2)
y changes by +36 (from -31 to 5)
so, the slope is +36/-6 = -6
and the equation looks now like this
y = -6x + b
let's use the second point
5 = -6×-2 + b = 12 + b
-7 = b
the full equation is
y = -6x - 7
