Answer:
0
Step-by-step explanation:
(x,y) slope is change in y / change in x⇒ Δy/Δx
(6,2)
(-18,2)
Δy = 2-2 = 0
Δx = 6-(-18) = 24
because the y values are the same, when you subtract you a slope of 0/24 or just 0 a horizontal line (because y is always =2)

a bag contains 18 marbles. there are 6 red marbles, 6 yellow marbles, and 6 green marbles. a marble is drawn at random and returned. then another marble is drawn at random
which statements are true?
A. the expected probability of drawing a green marble first is the same as the expected probability of drawing a green marble second.
B. there are six possible outcomes
C. the probability of drawing a red marble first is the same as not drawing a red marble second
D. the expected probability of drawing a red marble and then a yellow marble is 1/9
E. there are three possible outcomes from drawing the same color twice
F. the probability of drawing a yellow marble and then a yellow marble is 1/6
Answer:
Step-by-step explanation:
A. False. The probability of drawing a green marble twice is even smaller (It may be true though depending on what the question is asking, if it is asking the chance of drawing a green marble second is the same as the 1st chance, then yes it is True.
B.False
C. False
D.True, 1/3*1/3 (Simplified version of 6/18*6/18) is 1/9
E. False (Although this may be true, again depending on the type of question)
F. False
Solve for x in the given equation: ax - b = c
An equation is formed of two equal expressions. The value of x is the equation ax-b=c is (c+b)/(a).
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The solution of x in the given equation can be written as,
[tex]ax - b = c\\\\ax = c+b\\\\x = \dfrac{c+b}{a}[/tex]
Hence, the value of x is the equation ax-b=c is (c+b)/(a).

n = _____
Explaination :
The given equation,
[tex] \boxed{\sf{5n \: - 6(n - 2) \: = \: 19}} \: \bigstar[/tex]Lets start solving it..!!
★ Multiplying -6 by (n -2),
[tex] \implies \: \sf{5n \: - 6 \times (n - 2) \: = \: 19} [/tex]
[tex] \implies \: \sf{5n \: - 6n + 12 \: = \: 19} [/tex]
★ Subtracting 5n from 6n,
[tex]\implies \: \sf{ - n + 12 \: = \: 19} [/tex]
★ Transposing 12 from L.H.S. to R.H.S. it would be in negative,
[tex]\implies \: \sf{ - n \: = \: 19 - 12} [/tex]
★ On subtracting 12 from 19 we gets,
[tex] \implies \: \sf{ - n \: = \: 7} [/tex]

Find the slope of the line.
Answer:
-1/2
Step-by-step explanation:
Use the two points shown.
slope = rise/run
Start at teh left point.
Go down 2 units. That is a rise of -2.
Now go right 4 units. That is a run of 4.
slope = rise/run = -2/4 = -1/2

Can someone help me find the volume of this?
Answer:
97.2 m³
Step-by-step explanation:
The volume of a triangular prism is half the volume of a rectangular prism with the same length, width, and height.
V = 1/2LWH
V = 1/2(9 m)(7.2 m)(3 m) = 97.2 m³
_____
Additional comment
The relation we used above comes from the more general formula for the volume of a prism:
V = Bh
where B is the area of the base.
You know a rectangular base will have an area of ...
A = bh
and a triangle with the same base and height will have an area of ...
A = 1/2bh
That is, the base area of a triangle is half that of a rectangle with the same dimensions. When we use this fact in the volume formula, we find the volume of a triangular prism is 1/2 that of a rectangular prism with the same length, width, and height.

The number of bats in a colony is growing exponentially. After 1 year, there were 70 bats. After 4 years, there were 560 bats. If the colony continues to grow at the same rate, how many bats are expected to be in the colony after 7 years?
Answer:
23040 bats
Step-by-step explanation:
Let N(t) be the number of bats at time
We know that exponential function
[tex]y = ab[/tex]
According to question
[tex]N(t) = ab^{2}[/tex]
Where t (in years)
Substitute t=2 and N(2)=180
[tex]180 = ab^{2}[/tex]
Substitute t=5 and N(5)=1440
[tex]1440 = ab^{5}[/tex]
Equation (1) divided by equation (2)
[tex]\frac{180}{1440} = \frac{ab^{2} }{ab^{5}} = \frac{1}{b\frac{5-2}{}}[/tex]
By using the property
Substitute the values of b in equation (1)
Substitute t=9
Hence, after 9 years the expected bats in the colony=23040 bats

Answer:
[tex]\frac{-3}{-26}[/tex]
Step-by-step explanation:
[tex]\frac{-x-8}{x^{2}-4x-21}[/tex] is what you are looking for.
So with x = -5, it would look like this
[tex]\frac{-(-5)-8}{-5^{2}-(-5)4-21}[/tex]
Simple math now.
-(-5) is 5
[tex]-5^{2} = -25[/tex]
-5 * -4 = 20.
So it should be [tex]\frac{5-8}{-25+20-21}[/tex]
5-8=-3
-25+20-21 = -26
So the answer is[tex]\frac{-3}{-26}[/tex]

Three hundred eighty-five defective alcohol swabs were produced in a day. If 4% of the alcohol swabs produced were defective, how many alcohol swabs
were produced in all?
Answer:
9625
Step-by-step explanation:
If 385 alcohol swabs were defective, then 385 is 4% of all produced alcohol swabs.
385*25 = 9625
9625 alcohol swabs were produced
The number of alcohol swabs produced in all was 9625.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is equivalent to the quantity of that value between 1 and 100, and it is highly helpful for forecasting. For instance, if you say 678, we must also know the whole number, but if you say 80%, it is obvious.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
Let's say the total of x number of alcohol produced
4 percent were defective so
0.04 × x = 384
x = 9625 hence a total of 9625 alcohol was produced.

1/5 = 2/3x; x =
We can simply solve the equations by just dividing by the coefficient value of x. For example, we would divide both sides of the first equation by 8 to make the equation into x = 2/24 = 1/12
8x=2/3 --> x=1/12
1.5=2x --> x=0.75
