what is the equation of y=mx if the slope is 1/2
Answers
The slope 1/2 means that if you start at any point on the line and go to the right two and up one, you will hit the line again. That means the there are an infinite number of parallel lines that can have 1/2 as their slope. Each one has a formula (y=mx+b is the general slope-intercept formula, with b being the height at which that line crosses the y axis) using 1/2 as its m, and the b changes to show the y-intercept for that particular line. As an example, y=1/2x+2 is a line with the slope we described and it crosses the y axis at (0,2). Raise the value of b and the line moves to the right (and keeps the same slope, or lean). Reduce the value of b, and it slides to the left.
Your equation should be your y intercept (m) multiplied by x, then you would add .5 (or 1/5) and if y equals your y coordinate you did it right
A bag contained 18 red marbles, 14 green marbles, and 20 blue marbles. A marble was randomly pulled, the color recorded, and then put back into the bag. This table above shows the results after 25 pulls.
What was the relative frequency of selecting a red or blue marble?
Red:8
Blue8
Green9
Answers
Number of red marbles pulled = 8
Number of blue marbles pulled = 8
Total marbles pulled = 25
Relative Frequency = Total Frequency / Total number of data values
Relative Frequency of red marble = 8/25
= 32%
Relative Frequency of blue marble = 8/25

2 + 3 = 5
5 parts = 200 students
1 part = 200 ÷ 5 = 40 students
Therefore,the students who liked Nepali(2 parts) = 2 × 40 = 80
The students who liked Social Studies(3 parts) = 3 × 40 = 120

There are 2 Senators from each of 50 states. We wish to make a 3-Senator committee in which no two members are from the same state. How many ways can the 3-Senator committee be formed such that no two Senators are from the same state?
Answers
Answer:
156800 Ways
Step-by-step explanation:
Since 3 states can be represented in 19600 ways, -->
now we have 2 ways different from the 1st of the 3 states -->
We can also select in 2 independent ways from the second of the 3 states -->
and 2 ways from the third of the 3 stats
This gives us 2 x 2 x 2 x 19600 or => 8 x 19600 giving us 156800 ways
Thus, we have our answer of 156800 ways
Hope this helps!
There are 2352 ways for the 3 - Senator committee be formed such that no two Senators are from the same state.
What is Combination?
A combination is a way to of selecting things from a collection, where the order of selection does not matter.
It can be defined as;
\(^{n} C_{r} = \frac{n!}{(n-r)! r!}\)
Given that;
There are 2 Senators from each of 50 states.
We wish to make a 3-Senator committee in which no two members are from the same state.
Now,
Since, Each committee should be formed with 3 members.
Let fix a senator for any of 50 states, so we get new condition we need to combined 49 senators in group of 2.
Hence, We can formulate;
\(^{n} C_{r} = \frac{n!}{(n-r)! r!}\)
\(^{49} C_{2} = \frac{49!}{(49-2)! 2!}\)
\(^{49} C_{2} = 1176\)
So, we can choose in 1176 different ways a senator for a given state.
Hence, The ways for choose in 1176 different ways 2 senator for a given state.
= 1176 x 2
= 2352.
Thus, There are 2352 ways for the 3 - Senator committee be formed such that no two Senators are from the same state.

w=3x+7y solve for y in doing a class paper and im super confused
Answers
To solve for y, we need to isolate it. Start by moving all of the values on the side the y is on that don't have y to the other side (kind of confusing the way I said it). By that, I mean subtract 3x from both sides:
W = 3x + 7y
W - 3x = 7y
Now, divide both sides by 7 to find the value of y:
W - 3x = 7y
(W - 3x)/7 = y

Three research departments have 8 ,10 , and 7 members, respectively. Each department is to select a delegate and an alternate to represent the department at a conference. In how many ways can this be done?
Answers
We can conclude that exists 211680 ways.
How many ways can this be done?We know that the three research department is have 8, 10, and 7 members.
We choose a delegate and an alternate to represent the department.
First case: department have 8 members.
So, for a delegate, we have 8 options, and for a alternate 7, so a total of
\(8 \times 7 = 56 \ \text{options}\)
Second case: department have 10 members.
So, for a delegate, we have 10 options, and for a alternate 9, so a total of
\(10\times 9 =90 \ \text{options}\)
Third case: department have 7 members.
So, for a delegate, we have 7 options, and for a alternate 6, so a total of
\(7\times6 = 42 \ \text{options}\)
Therefore, we get:
\(56 \times 90 \times 42 = \bold{211680}\)
Hence, we conclude that exists 211680 ways.

https://brainly.com/question/30958797
For the first department with 8 members, there are 8 choices for selecting a delegate. After choosing a delegate, there remain 7 members, so there are 7 choices for selecting an alternate. Therefore, there are 8 × 7 = 56 ways to select a delegate and an alternate from the first department.
Similarly, for the second department with 10 members, there are 10 choices for selecting a delegate and 9 choices for selecting an alternate. Hence, there are 10 × 9 = 90 ways to select a delegate and an alternate from the second department.
For the third department with 7 members, there are 7 choices for selecting a delegate and 6 choices for selecting an alternate. Thus, there are 7 × 6 = 42 ways to select a delegate and an alternate from the third department.
To find the total number of ways to select delegates and alternates from all three departments, we multiply the number of choices for each department together:
56 × 90 × 42 = 211,680.
Therefore, there are 211,680 ways to select a delegate and an alternate from each department.
Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

cup vegetable oil
1 large egg
4 tablespoons sour cream
2 medium-sized ripe bananas, mashed
1 cups all-purpose flour
1 teaspoon baking soda
teaspoon salt
1 teaspoon vanilla extract
pinch of nutmeg
You will use the recipe above to answer the following questions:
This recipe serves 10, but you need to serve 30. What number will you need to multiply the amount of each ingredient by to adjust the recipe? How did you determine this number?
How much vegetable oil do you need for 30 cupcakes?
How much flour do you need for 30 cupcakes?
What is the difference in the amount of vanilla extract you would need for 30 cupcakes?
What is the difference in the amount of salt you would need for 30 cupcakes?
In the real world, even though you make adjustments to a recipe to accommodate the number of people you need to serve, you sometimes round the amount of an ingredient instead of using an exact amount. Which ingredient would it make more sense to round rather than coming up with the exact amount? Why?
Answers
Answer: Hey give me 1 hour and ill answer it I'm doing odessyware rn so Ill get back to you later appreciate yo patients.
Step-by-step explanation:
Then, if we want to make 30 servings, we need to use that recipe 3 times. (because x*10 = 30, then x = 30/10 = 3)
This would be equivalent to multiply each ingredient by 3.
for 30 cupcakes we need:
3 cups of vegetable oil.
3 cups of all-purpose flour
(because for each one of these ingredients we needed only 1 cup to make 10 cupcakes).
for 10 cupcakes we need 1 teaspoon of vanilla.
for 30 cupcakes we need 3 teaspoons of vanilla, the difference is 3 - 1 = 2.
So the difference is 2 teaspoons.
About which quantities we should round are those where we may have mixed numbers or big numbers.
For example, we have 4 tablespoons of sour cream for 10 servings, then for 30 servings we should have:
3*4 = 12 tablespoons.
We could round this down to 10 tablespoons.
