Answer:

V = 9.828 * 10^7 mm^3

a= 9.828 b = 7

9,827,000 mm^3

Step-by-step explanation:

The volume of a rectangular prism is

V = l*w*h

V = 1.2 *10^3 * 3.9*10^2 * 2.1*10^2

We multiply the numbers out front and add the exponents (the powers of 10)

V = (1.2*3.9*2.1) * 10^(3+2+2)

V = 9.828 * 10^7 mm^3

Rewriting this in standard form means moving the decimal 7 places to the left. Since there is not enough places add zeros

9,827,000 mm^3

Dima020 [189]

Answer:

Step-by-step explanation:

Given that a study of the checkout lines at the Safeway Supermarket in the South Strand area revealed that between 4 and 7 P.M. on weekdays there is an average of four customers waiting in line.

Let X be the number of customers waiting in line

X is Poisson with parameter = 4

the probability that you visit Safeway today during this period and find:

a. No customers are waiting

$P(X=0) = 0.018316$

b. Four customers are waiting?

$=P(x=4) =0.193567$

c. Four or fewer are waiting?

= $P(X\leq 4) = 0.628837$

d. Four or more are waiting

= $P(X\geq 4)=0.56653$
