"What is a variable?
A variable is used in a Fair Test. A variable is any one of the elements of the test which could be changed. They can change the outcome of an experiment.
In a fair test, only one variable is allowed to be manipulated – all others have to be kept the same,or “controlled”."

A rectangle has an area of 24 square inches. The rectangle is reduced by a scale factor of 1/2 . What is the area of the new rectangle?
Considering the scale factor of the reduction, it is found that the area of the new rectangle is of 6 square inches.
What is the area of a rectangle?
The area of a rectangle of length l and width w is given by:
[tex]A = lw[/tex]
In this problem, the rectangle is reduced by a scale factor of 1/2, hence:
[tex]l \rightarrow \frac{l}{2}, w \rightarrow \frac{w}{2}[/tex]
Then, the area is given by:
[tex]A = lw = \frac{l}{2} \times \frac{w}{2} = \frac{lw}{4}[/tex]
A rectangle has an area of 24 square inches, hence:
[tex]lw = 24[/tex]
Thus:
[tex]A = \frac{lw}{4} = \frac{24}{4} = 6[/tex]
The area of the new rectangle is of 6 square inches.

Using Abdul's simulation, what is the probability of rolling a 2 on the number cube and the coin landing heads up? (5 points)
Answer:
450/10000
Step-by-step explanation:
Probability of rolling a 2 : 10/100
Probability of getting heads up : 45/100
Probability of both together : 10/100 * 45/100 = 450/10000

In one paragraph, using your own words, describe a commercial you have seen recently and tell what the commercial was selling and what the hidden message was in it.
Answer:
A commercial I have seen recently was the Grub Hub commercial. The commercial was advertising all the types of food you could possibly buy with Grub Hub. It seems their point in this commercial was to bring consumers (people who buy the food) in and purchase their food using the Grub Hub app. Grub Hub did this by making jokes and trying to be funny with the commercial. The people in the commercial were dancing and smirking while they smacked on the "delicious" food and apparently the food was so good and tasty that even a PREGNANT woman did the splits. So basically it was not a normal commercial it was... really special. The hidden message was that it's "better" than Uber.

Step-by-step explanation:
x+47=90
x=43
----------------
y+x=90
put in 43 for x
y+43=90
y=47
Hope that helps :)
Answer:
X=43
y=47
Step-by-step explanation:
Well you have 47 degrees. Finding X first would be easier.
X and 47 are complementary (90 degreees) so you can subtract 47 from 90 and get “x” Which is 43.
Now for y.
Y and X is complementary also, which means since x is 43, 90-43 is 47. So y is 47.
