Answer:
1.5 feet
Step-by-step explanation:
12/8 = 1.5 feet
The t-value measures the size of the difference relative to the variation in your sample data. Put another way, T is simply the calculated difference represented in units of standard error. The greater the magnitude of T, the greater the evidence against the null hypothesis.

Answer:
Sample Space:
1. (real, white)
2. (real, silver)
3. (real, gold)
4. (real, purple)
5. (fake, white)
6. (fake, silver)
7. (fake, gold)
8. (fake, purple)
Step-by-step explanation:
Nour and Rana each created a display to represent the sample space of randomly picking a type of tree and a color for the ornaments.
Whose display correctly represents the sample space?
We are not given their sample space but still you can compare the sample space you have with this one to find out whether it is correct or not.
There are 2 different types of Christmas trees
1. Real
2. Fake
There are 4 different types of colors for the ornaments
1. white
2. silver
3. gold
4. purple
The sample space is the set of all the possible outcomes of an experiment.
Then all of the possible outcomes are:
1. (real, white)
2. (real, silver)
3. (real, gold)
4. (real, purple)
5. (fake, white)
6. (fake, silver)
7. (fake, gold)
8. (fake, purple)
Therefore, there are total 8 possible outcomes.
Note: If your sample space matches with this one then it is correct otherwise it is not correct.
The correct quadratic equation;
x2+7x-2=0
Working
Assuming the frame has a uniform thickness;
Then length of mirror and frame is 3+x and width 2+x
The area of mirror and frame area;
A=L*W
8=(3+x)(2+x)
8=(6+5x+x2)
Taking 8 to the Right hand side, we have:
x2+5x-2 =0
