Suppose that x1, x2 and x3 are independent bernoulli random variables, each has expected value 2/3. • define x = x1 + x2 + x3. what is the expected value of x? what is the variance? • define y = 3x1. what is the expected value of y ? what is the variance? • is x a binomial random variable? • is y a binomial random variable? • calculate p(x = y ).

i am thinking c. sorry if im wrong .

step-by-step explanation:

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1
