Answer:it’s 10 raised to seven right
Step-by-step explanation:
1379= 1380
38=40
1380 x 40 = 55,200
Or you can use the ≈ sign which means about so
1380 x 40 ≈ 55200
Answer:
The correct answer is 2.2.
Step-by-step explanation:
The following represents the probability distribution for the daily demand of microcomputers at a local store:
Demand Probability
f(0)= .1
f(1)= .2
f(2)= .3
f(3)= .2
f(4)= .2.
Expectation of a discrete probability function f of the random variable x is given by ∑ x × f(x).
Thus the expected value of demand is given by
0.1 × 0 + 0.2 × 1 + 0.3 × 2 + 0.2 × 3 + 0.2 × 4 = 2.2.
The expected daily demand is 2.2.
Answer:
6x² + 5x - 6
Step-by-step explanation:
Given
(2x + 3)(3x - 2)
Each term in the second factor is multiplied by each term in the first factor, that is
2x(3x - 2) + 3(3x - 2) ← distribute both parenthesis
= 6x² - 4x + 9x - 6 ← collect like terms
= 6x² + 5x - 6
