Answer:
Slope= 2/3
Step-by-step explanation:
Here are our coordinates:
x1= 20
y1= 60
x2= 50
y2= 80
Now we use the slope formula-- y2-y1/x2-x1.
Now we plug in the numbers!
80-60= 20
=20/30
50-20= 30
Now we simplify: 20/10= 2
30/10=3
Thus your answer: 2/3

Directions: Write your own recipe for trail mix with a catchy name that will make people want to eat it. You can also create a slogan, logo, or package design for the mix. Your recipe must meet the following contest guidelines:
1. It must have at least five different ingredients.
2. The amount of each ingredient should be represented by a different mixed number.
3. The recipe must make exactly 10 cups of trail mix.
After you write your recipe, complete the following for your contest entry:
• Prove that your recipe makes exactly 10 cups.
• Explain the most efficient method for measuring each ingredient using only
the following two measuring cups: 31 cup and 41 cup. You can use one or both of the measuring cups. Note: Depending on the fractions that you chose
for your ingredient amounts, it may not be possible to create each exact amount using only 13 and 14 measuring cups. If you need to, you can round your ingredient amounts using benchmarks and then explain how you would estimate that amount. For example, if you need 74 cup of an ingredient, 74
cup is slightly more than 12 cup. You could fill up your 14 measuring cup twice to make 12 cup of that ingredient, and then add just a tiny bit more to estimate 74 cup.
• Use equations or other models to show how you would measure each ingredient amount with only the two measuring cup sizes.

Lost-time accidents occur in a company at a mean rate of 0.3 per day. What is the probability that the number of lost-time accidents occurring over a period of 9 days will be no more than 3? Round your answer to four decimal places.
Answers
Answer:
0.7295
Step-by-step explanation:
Given that :
Mean rate of lost time accident = 0.3 per day
probability that the number of lost-time accidents occurring over a period of 9 days will be no more than 3?
n = 9
Using binomial distribution formula :
P(x ≤3)
Probability of success (p) = 0.3
1 - p = 1- 0.3 = 0.7
nCx * p^x * (1 - p)^(n-x)
Using the binomial probability distribution calculator to save computation time :
P(x ≤3) = P(x = 0) + p(x = 1) + p(x = 2) + p(x = 3)
P(x ≤3) = 0.0403 + 0.1556 + 0.2668 + 0.2668
P(x ≤3) = 0.7295
Probabilities are used to determine the chances of events.
The probability that accidents occur no more than 3 days in 9 days is 0.7296
The given parameters are:
[tex]p = 0.3[/tex] --- the probability that an accident occurs
The probability that an accident does not occur (q) is then calculated using the following complement rule
[tex]q= 1 - p[/tex]
[tex]q= 1 - 0.3[/tex]
[tex]q= 0.7[/tex]
The probability that accidents occur no more than 3 days in 9 days is
[tex]P(x \le 3) = P(0) + P(1) + P(2) + P(3)[/tex]
Each probability is calculated using:
[tex]P = ^nC_rp^rq^{n-r}[/tex]
So, we have:
[tex]P(x \le 3) = ^9C_0(0.3)^0(0.7)^9 +^9C_1(0.3)^1(0.7)^8 + ^9C_2(0.3)^2(0.7)^7 + ^9C_3(0.3)^3(0.7)^6[/tex]
This gives
[tex]P(x \le 3) = 0.0403 + 0.1556 + 0.2668 + 0.2669[/tex]
[tex]P(x \le 3) = 0.7296[/tex]
Hence, the probability that accidents occur no more than 3 days in 9 days is 0.7296

Step-by-step explanation:
5(9+4) can be expanded to get 5(9)+5(4). And 5(4)=20.
Answer:
Option D
Step-by-step explanation:
This will seem weird but all you are is doing distrubitive property.
Replace w with nine and you have this.
Step 1 (Replace/Substitute)
5(9 + 4)
5(9) + 20
We distribute the five to the numbers in the parentheses. Or we multiply 5 to the other numbers within the parentheses.

A number of squares are connected in a row to form a rectangle. The
table shows the relationship between the number of squares, x, and the
perimeter, y, of the rectangles they form. Select all the true statements
about this relation.
Answers
Answer:
✅The relation is a function
✅The graph of the function is linear
✅The table can be represented by the equation, [tex] y = 4x + 4 [/tex]
Step-by-step explanation:
✅The relation is a function because each domain (number of squares) has exactly one range (perimeter).
✅The graph of the function is linear because the difference between any two successive y-values gives us the same value of 4.
That is: 12 - 8 = 16 - 12 = 20 - 16 = 4.
✅The table can be represented by the equation, [tex] y = 4x + 4 [/tex], because if we substitute any pair of values (x, y) into the equation, the equation would be true.
For example, using the pair (1, 8), substitute x = 1, and y = 8 in [tex] y = 4x + 4 [/tex].
Thus:
[tex] 8 = 4(1) + 4 [/tex]
[tex] 8 = 8 [/tex] (True).

A triangle with a vertex at point Y(-3, 7) is dilated by a scale factor represented by the coordinate pair (2/3x, 2/3y ). What is the location of Y'?
Please look at the picture below for the answer choices.
Answers
Answer:
[tex]Y' = (-2, 4\frac{2}{3})[/tex]
Step-by-step explanation:
Given
[tex]Y = (-3,7)[/tex]
[tex]Scale\ Factor = (\frac{2}{3}x,\frac{2}{3}y)[/tex]
Required
Determine Y'
Y' can be solved by multiplying the scale factor by Y
i.e.
[tex]Y' = Scale\ Factor * Y[/tex]
For, the x coordinates.
[tex]Y' = \frac{2}{3}x[/tex]
Where
[tex]x = -3[/tex]
[tex]Y' = \frac{2}{3} * -3[/tex]
[tex]Y' = \frac{-6}{3}[/tex]
[tex]Y = -2[/tex]
For the y coordinates:
[tex]Y' = \frac{2}{3}y[/tex]
Where
[tex]y = 7[/tex]
[tex]Y' = \frac{2}{3} * 7[/tex]
[tex]Y' = \frac{14}{3}[/tex]
[tex]Y' = 4\frac{2}{3}[/tex]
Hence:
[tex]Y' = (-2, 4\frac{2}{3})[/tex]

Downloads cost $______for a song and $________for a movie.
Answers
Answer:
Downloaded music 1 EACH: $1
Movie 1 EACH: $12
Step-by-step explanation:
4 songs and 1 movie = $16
6 songs and 1 movie = $18

2 songs = $2
Try it out on the formula, it will work.
$4 + x = $16
