F(-5) just means that your substituting the number -5 for every x value. So if you have x+1 this would be -5+1 which is -4

OverLord2011 [107]

Complete question is;

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.

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.

F(x) = 6x^2 find the inverse
anygoal [31]

Answer:

The inverse is ±sqrt(x/6)

Step-by-step explanation:

Let y = 6x^2

To find the inverse, exchange x and y and then solve for y

Exchange x and y

x = 6y^2

Solve for y

Divide each side by 6

x/6 = 6y^2 /6

x/6 = y^2

Take the square root of each side

±sqrt(x/6) = sqrt(y^2)

±sqrt(x/6) =y

The inverse is ±sqrt(x/6)

The total cost of flooring a room at Rs .9.50 per square meter is Rs 760, If the length of the room is 10 m, find its breadth.
Jobisdone [24]

Answer:

8 metre

Step-by-step explanation:

cost of flooring per square metre = Rs .9.50

total cost of flooring= Rs760

Area of room= 760/9.50

= 80 m^2

Area of the given room= Lenght × Breadth

length of the room is = 10 m

80= 10 × Breadth

Breadth= 80/10= 8 m

Hence, breadth of the room is 8metre

The school track is 2/3 of a mile long. how far wuld you run if you took 9 laps around the track?
kakasveta [241]

Step-by-step explanation:

distance \: run \: in \: one \: lap  \\  =  \frac{2}{3}  \: miles \\  \\  \therefore \:distance \: run \: in \:9 \: laps \:  \\   =  \frac{2}{3}  \times 9 \\  = 2 \times 3 \\  = 6 \: miles

Hence, in 9 laps you will run 6 miles.
