Answer: To find the height of a rectangle with a base of 12 cm and an area of 60 cm², we can use the formula:
Area=Base×Height
Rearranging this formula to solve for the height, we get:
Height=BaseArea
Substituting the given values, we get:
Height=12 cm60 cm²=5 cm
Therefore, Chloe is the only student who wrote the correct formula to find the height of the rectangle. The correct formula is:
Height=Base Area

Step-by-step explanation:
The expected value E[(1-x)(1-x)] is 1/4. This represents the average value of the function (1-x)(1-x) for the given probability distribution of x values.
We are given an indicator variable x with values 0 and 1. The probability of x = 0 is 1/4 and x = 1 is 3/4. We need to find the expected value E[(1-x)(1-x)].
Step 1: Determine the function we are working with.
We have the function (1-x)(1-x), which simplifies to (1-2x+x^2).
Step 2: Find the probabilities for each value of x.
For x = 0, the probability is 1/4.
For x = 1, the probability is 3/4.
Step 3: Compute the function values for each x value.
For x = 0, (1-2(0)+0^2) = 1.
For x = 1, (1-2(1)+1^2) = 0.
Step 4: Calculate the expected value.
E[(1-x)(1-x)] = (1)(1/4) + (0)(3/4) = 1/4.

Answer:
x<10
Step-by-step explanation:
Isolate X:
2x-8+8<12+8 = 2x<20
Then divide by 2:
2x/2<20/2 = x<10
x<10
