The probability of an event is the number of favorable outcomes divided by the total number of outcomes possible. Converting the fraction 35 to a decimal, we would say there is a 0.6 probability of choosing a banana. This basic definition of probability assumes that all the outcomes are equally likely to occur.

Step-by-step explanation:
A pair of equations is shown below: y = 3x - 5 y = 6x - 8
Part A: Explain how you will solve the pair of equations by substitution or elimination. Show all the steps and write the solution. (5 points)
Part B: If the two equations are graphed, at what point will the lines representing the two equations intersect? Explain your answer. (5 points)
Answer:
See below
Step-by-step explanation:
y = 3x -5 <===== multiply this equation by -2 to get
-2y = -6x+10 now add it to the other equation(this will ELIMINATE x)
y = 6x-8
-y = +2
y = -2 then sub this in to oneof the quations to find x = 1
the two points will intersect at x,y = 1,-2 (because this satisfies both of the equations)
PART A
We start with: y = 3x - 5 y = 6x - 8
Elimination:
If we have two equations that = y, then we can make them equal each other:y = y3x - 5 = 6x - 8We then collect the x term together:3x - 6x = -8 + 5-3x = -3We can divide both sides by -3:x = 1Substitution
We can make one equation turn from a y= to an x=I decided to go with y = 3x - 5 (but it doesn't matter)We basically want to get it into x=y = 3x - 5y + 5 = 3x3x = y + 5 (I'm just flipping the equation to get x on the left for easiness)We then divide both sides by 3:x = [tex]\frac{y + 5}{3}[/tex]Don't forget we've also got y = 6x - 8So we just put x in!y = 6 × [tex]\frac{y + 5}{3}[/tex] - 8y = [tex]\frac{6}{3}[/tex] × (y + 5) - 8y = 2 × (y + 5) - 8y = 2y + 10 - 8y = 2y + 2Rearrange to get y on one side:-y = 2Times both sides by -1:y = -2We can now go back to...x = [tex]\frac{y + 5}{3}[/tex]By putting y = -2 in:x = [tex]\frac{-2 + 5}{3}[/tex]x = [tex]\frac{3}{3}[/tex] = 1PART B
We can find where they intersect/overlap by using elimination/substiutionWe've already covered both, and we get x = 1This means we've already go the x-coordinate of our point where the lines meet(x, y) = (1, ?)We just put our value of x into either equation (since x = 1 is where they meet)I'll go with y = 6x - 8y = 6 × 1 - 8y = 6 - 8 = -2We end up with (1, -2)!!!P.S.:
I've attached a screenshot of the graphs, notice how they meet at (1, -2)

suppose you have a box with 3 blue marbles, 2 red marbles, and 4 yellow parmbles. you are going to pull out one marble, record its color, remove it from the box and draw another marble. what is the probability of pulling out a red marble followed by a blue marble? the multiplication rule says to use P(red) P(blue).
1. Describe the probability of finding a red marble.
2. describe the probability of finding a blue marble.
3. describe the process of finding the probability of finding a red marble followed by a blue marble if the first marble was permanently removed?
4. what effect did removing the first marble from the box have on the problem
5. describe the probability of finding a red marble followed by the blue marble if the first marble is removed?
Answer:
Step-by-step explanation:
Part A
The probability of finding a red marble. P(red) = red / total
Total = red + yellow + blue
Total = 2 + 4 + 3
Total = 9
P(red) = 2/9 = 0.22222
Part B
P(blue) = blue / total
P(blue) = 3/8 = 0.375
This means that the red marble is permanently gone. The total is different. It is eight not nine.
Part C
The probability of red followed by blue is just the answers to A and B multiplied.
P(red) followed by blue = 2/9 * 3/8
P(red) followed by blue = 0.22222 * 3.75
P(red) followed by blue = 0.0833333
If you are confident of your concellation abilities you could do this as
P(red followed by blue) = 2/9 * 3/8 = 1/3 *1/4 = 1/12 = 0.083333....
Part D
Removing the first marble had the affect of reducing the total number of marbles to 8 and the number of reds from 2 downto 1
Part E
The answer here is 1/12.

divide Rs 120 between two students so that one gets 4 times as much as the other
Answer:
One gets Rs 24 and the other Rs 96.
Step-by-step explanation:
Number of parts = 1 + 4 = 5
So one student gets 1/5 of 120 and the other gets 4/5 of 120
120 * 1/5 = 24
120 *4/5 = 4*24 = 96.
Answer:
One would get 96 and another would get 24
Step-by-step explanation:
So first lets create an equation from the words where 4x is what one students has and x is what another has :
120 = 4x + x
Lets solve this now!
120 = 5x (divide by 5 on both sides)
24 = x (1st Student)
(Multiply by 4 on both side to get the second student)
96 =4x (2nd Student)

For a craft project, you select the four packages of modeling clay and the set of tools shown at the right. If there is a 6% sales tax, what is the total cost?
Answer:
13.727
Step-by-step explanation:
Explanation
Given: You choose the four packages of modeling clay and the set of equipment indicated on the right for a creative project.
To find: the total cost if there is a 6% sales tax.
We will calculate the total cost of each item and then add.
Tip
The total cost formula is used to combine the variable and fixed costs of providing goods to determine a total.
The formula is: Total cost = (Average fixed cost x average variable cost) x Number of units produced.
Step 1
The cost of 4 packets of clay is given by:
4 x $2.79
Step 2
We will calculate the product:
4 x 2.79 = 11.16
Step 3
We will add the cost of 4 packets of clay and a pack of tools to get the total cost without tax:
$(11.16 + 1.79)
Step 4
We will add the numbers:
11.16 + 1.79 = 12.95
Step 5
The 6% tax on the total price is given by:
6% x $12.95
Step 6
We will calculate the sales tax:
6/100 x 12.95 = 0.777
Step 7
We will add the total cost without tax and tax amount to get the total amount paid:
$(12.95 + 0.777)
Step 8
We will add the amounts:
12.95 + 0.777 = 13.727
Step 9

The base of a prism has an area of 6.6 cm2. The height is 2.4 cm. What is the volume
So the volume is 15.84 cm The formula for the volume of a prism is given by the product of the area of the base and height of the prism. Thus, the volume of a prism can be given as V = B × H where V is the volume, B base area, and H height of the prism.
What is the value of x in the equation 4 (2x + 14) = 0?
9, 7, -7, -9.
Answer:
x = -7
Step-by-step explanation:
First step is to expand the left side of the equation. To do this, multiple 4 by each term on the inside of the paratheses.
4 * 2x = 8x
4 * 14 = 56
This gives you the equation:
8x + 56 = 0
Now, get the x term on one side by itself by subtracting 56 on both sides:
8x = -56
And solve for x by dividing both sides by 8:
x = -7

It is always helpful to rewrite a quadratic equation in standard form as a first step in solving it.
A. FALSE
B. TRUE
Answer:
A
Step-by-step explanation:
Now when I think of solving it, I think of finding the zeros. Now if you start with the form, for example:
[tex](x+3)(x-3)[/tex]
Then you can easily see the zeros are -3 and 3.
But if you start with the standard form:
[tex]ax^2+bx+c=0\\or\\x^2-9[/tex]
It will be harder to find the zeros and you would do the eqation or factor it.
So if your in the factored form don't go to standard to find the zeros.
The given statement is False.
What is a quadratic equation?An equation with highest degree two, is considered as a quadratic equation.
In standard form, the right side of an equation should be 0 and every component on the left side should be 1.
For example, x² = 4; to express this in standard form, move the number 4 to the left side of the equation, resulting in x² - 4 = 0.
If you are asked to find x in this circumstance, there is no need to write the equation in standard form; simply take this same real number of both of the equation's sides to find x.
Hence, it is not always necessary to write the quadratic equation in standard form then solve.

The height of a candle decreases from 10 centimeters to 6 3/4 centimeters after burning for 1/2 hour
The true statement is as follows:
The product 13 / 4 × 2 can be used to find the unit rate in cm per hour.
After one hour, the height of the candle will have decreased by 6 1 / 2 cm.
What is rate?Rate is the ratio between two related quantities in different units.
The height of the candle decreases from 10 cm to 6 3 / 4 cm after burning for 1 / 2 hours.
6 3 / 4 cm = 27 / 4 cm
10 - 27 / 4 = 40 - 27 / 4 = 13 / 4 cm
Therefore, 13 / 4 cm of candles were lost in 1 / 2 hours.
Rate = 13 / 4 × 2 = 26 / 4 = 13 / 2 cm per hour
Therefore, the product 13 / 4 × 2 can be used to find the unit rate in cm per hour.
13 / 4 + 13 / 4 = 13 + 13/ 4 = 26 / 4 = 13 / 2 = 6 1 / 2 cm.
Therefore, after one hour, the height of the candle will have decreased by 6 1 / 2 cm.
