Well, your ratio given is 18 to 4. so multiply both numbers (18 and 4) by some number and you will have an equivalent ratio. 
example: if you had 2 times as many people, then an equivalent ratio would be 18*2 to 4*2 = 36 to 8

A taxi driver provides service in two zones of a city. Fares picked up in zone A will have destinations in zone A with a probabi
sammy [17]

Answer:

The taxi driver's average profit per trip is 4.4.

Step-by-step explanation:

Probability of fares picked up in zone A with destinations in zone A = 0.6

Probability of fares picked up in zone A with destinations in zone B = 0.4

Probability of fares picked up in zone B with destinations in zone A = 0.3

Probability of fares picked up in zone B with destinations in zone B = 0.7

The driver's expected profit for a trip entirely in zone A = 6

The driver's expected profit for a trip entirely in zone B = 8

The driver's expected profit for a trip involving both zones is 12

The taxi driver's average profit per trip:

zone A with destinations in zone A = 0.6 * 6 =  3.6

zone A with destinations in zone B = 0.4 * 12 = 4.8

zone B with destinations in zone A = 0.3 * 12 = 3.6

zone B with destinations in zone B = 0.7 * 8 =  5.6

Total profit expected for 4 trips =                     17.6

Average profit per trip = 4.4 (17.6/4)

The graphs below have the same shape. What is the equation of the graph of g(x)?
maw [93]

Answer:

A

Step-by-step explanation:

Given f(x) then f(x + a) is a horizontal translation of f(x)

• If a > 0 then a shift to the left of a units

• If a < 0 then a shift to the right of a units

Here g(x) is the graph of f(x) = x²  shifted 4 units to the left, hence

g(x) = (x + 4)² → A
