Answer:
12x
Explanation:
3x − 10 + 2x + 3x + x + 20 + 2x + 10 + x − 20
= 3x + −10 + 2x + 3x + x + 20 + 2x + 10 + x + −20
Combine Like Terms
= 3x + −10 + 2x + 3x + x + 20 + 2x + 10 + x + −20
= (3x + 2x + 3x + x + 2x + x) + (-10 + 20 + 10 + −20)
= 12x

The power is 2 because the numbers of both numerator and denominator are multiplied in double that is 8*8 = 8^2 = 64 and 9*9 = 9^2 = 81
Answer:
a. E(F)=0.875
b. 99.9976%
c. P(X=2)=0.1683
Step-by-step explanation:
a. We notice that this is a binomial distribution with the probability of success;
#We are given the sample size, n=7. The Expected value is calculated as:
Hence the expectation, E(F)=0.875
b. To calculate the probability of the range of F, we need to calculate all possible outcomes of F in the given sample;
Hence, the range of F is 99.9976%
c. The probability that F=2 is calculated using the binomial distribution function as:
Hence, the probability of F=2 is 0.1683
