Answer:
3/0 = Undefined
Step-by-step explanation:
The equation to find the slope of two different points is [tex]\frac{y2-y1}{x2-x1}[/tex]. Now, all you have to do is substitute the values in the equation so that it now looks like [tex]\\\\\frac{7-4}{4-4} = \frac{3}{0}[/tex]. Since you can't divide 3 by 0 it is considered to be undefined, meaning there are no slope for the two ordered pairs.
Bart believes that mice exposed to microwaves will become extra strong (maybe he's been reading too much Radioactive Man). He decides to perform this experiment by placing 10 mice in a microwave for 10 seconds. He compared these 10 mice to another 10 mice that had not been exposed. His test consisted of a heavy block of wood that blocked the mouse food. He found that 8 out of 10 of the microwaved mice were able to push the block out of the way. 7 out of 10 of the non-microwaved mice were able to do the same.
Complete question is;

He found that 8 out of 10 of the microwaved mice were able to push the block out of the way. 7 out of 10 of the non-microwaved mice were able to do the same.
Identify the following;
1) Control group
2) Independent variable
3) Dependent variable
4) What should bart's conclusion be?
5) How could Bart's experiment be improved?
Answer:
1) Mice not exposed to the microwave.
2) Amount of microwave radiation hitting the mice.
3) The strength of the mice exposed to the radiation.
4) Conclusion should be inconclusive.
5) Can be improved in 3 ways listed under explanation.
Step-by-step explanation:
1) The control group is the mice that were not exposed to the microwave heating. This is because a control group is a set of samples that are kept separate and not exposed to the independent variable.
2) The independent variable is the cause of the research. So in this case the independent variable is the amount of microwave radiation because the study is on how mice exposed to microwaves become extra strong.
3) Dependent variable: The dependent variable will be the strength of the mice that are exposed to the microwave radiation because the extra amount of strength depends on the radiation.
4) Bart's conclusion should be Inconclusive because even though there is difference in the results gotten from the exposure, they are not that significantly different and thus we can say that there is an equal chance of an effect or no effect.
5) Bart's experiment can be improved by the following;
- Using a larger sample size
- Increasing the amount of groups so as to have a varied amount of microwave radiation received by the exposed mice
- Increasing the mass of the block that's in front of the food.

In the alphabet, x comes before y. Use this fact to describe a method for remembering how to write ordered pairs.
Answer:
Step-by-step explanation:
so when remembering how to write ordered pairs, think of the monkey bars. you have to get there before you can climb up, x being walking to the monkey bars and y being climbing up them. Think of the steps to get to the monkey bars compared to the fact that x is before y. getting to the monkey bars comes before climbing them, is x (run) and climbing them would be y (rise), and not the other way around because like the question said; x comes before y.
I really hope this wasn't too confusing. I'm really sorry if it was!

Solve: 3x -6/3 = x + 3/6
Answer:
x= 1/2
Step-by-step explanation:
start by adding 6/3 to both sides. the negative 6/3 on the left side will disappear, and the right side will equal one. (6/3 + 3/6= 9/9 = 1).
Youll end up with:
3x=x+1
now, subtract x from both sides to get:
2x=1
Divide both sides by two to get
x=1/2

Jamal buys a new racing bicycle. Two shops charge the same price for the bicycle but offer different payment plans. Shop 1 requires $260 down and a monthly payment of $20. Shop 2 requires $140 down and a monthly payment of $30. Write an equation to represent the payment plans where m is the number of months payments are made.
Answer:
Shop 1 = $260 + $20m
Shop 2 = $140 + $30m
Step-by-step explanation:
m = number of months payments are made
Total payment made = down payment + monthly payment
Shop 1 requires $260 down and a monthly payment of $20.
Shop 1 = $260 + $20m
= 260 + 20m
Shop 2 requires $140 down and a monthly payment of $30.
Shop 2 = $140 + $30m
= 140 + 30m
The equations that represent the payments plans are:
Shop 1 = $260 + $20m
Shop 2 = $140 + $30m

If you had a triangle with side lengths of 2, 4, and 5, and
dilated it with a scale factor of 2.5, what would be the
side lengths of the resulting image?
Answer:
5,9,12.5
Step-by-step explanation:
After dilation, the final side lengths of the triangle become -
a' = 5 units, b' = 10 units, c' = 12.5 units
What is Dilation?A dilation is an enlargement or reduction of a figure about a center of dilation by a specified scale factor [k].
Given is a triangle with side lengths of 2, 4, and 5 and is dilated with a scale factor of 2.5
We have a triangle whose side lengths are -
a = 2 units
b = 4 units
c = 5 units
Scale factor = [k] = 2.5
Now, after dilation the final side lengths will become -
a' = 2.5a = 2.5 x 2 = 5 units
b' = 2.5b = 2.5 x 4 = 10 units
c' = 2.5c = 2.5 x 5 = 12.5 units
Therefore, after dilation, the final side lengths of the triangle become -
a' = 5 units, b' = 10 units, c' = 12.5 units

This is calculated as:
2/3 ounces of 1 bottle
2/3 ounces of 8 ounces
= 16/3 ounces
= 5 1/3 ounces or 5.3333333333 ounces

Step-by-step explanation:
Caleb’s school is five blocks due north of his home, and the library is two blocks due west of his home. If each city block is a square with sides measuring 275 feet, which of the following is the closest to the straight-line distance from Caleb’s school to the library?
Answer:
The closest straight-line distance from Caleb's school to the library is:
1480.92 feetStep-by-step explanation:
Imagine a triangle, where five blocks are a side and two blocks another side, to obtain the closest straight-line distance from Caleb's school to the library you can use the Pythagoras theorem, where the hypotenuse is the closest straight-line:
[tex]perpendicular^{2} +base^{2} =hypotenuse^{2}[/tex]Clearing the hypotenuse is:
[tex]\sqrt{perpendicular^{2}+base^{2}}= hypotenuse[/tex]Now, you only need to identify the distance in each case:
Five blocks = 275 feet * 5 = 1375 feet.
Two blocks = 275 feet * 2 = 550 feet.
At last, you must replace the distances found in the equation cleared:
[tex]\sqrt{1375 feet^{2}+550 feet^{2}}= hypotenuse[/tex]Hypotenuse or closest straight-line = 1480.92 feet.Identifying this, the closest straight-line distance from Caleb's school to the library is 1480.92 feet.
