Observations can you make from a comparison of the number of water supply stoppages reported by owner-occupied units versus renter-occupied units 1.

Total no. of times owner-occupied units had a water supply stoppage lasting 6 or more hours

547000 + 5012000 + 6110000 + 2544000 + 557000 = 14770000

x = no. of times owner-occupied units had a water supply stoppage.

<h3>What is the probability at x =0?</h3>

P(x=0) = 547000/14770000

P(x=0) = 0.0370

Similarly, we have at x=1

P(x=1) = 5012000/14770000

P(x=1) = 0.3393

P(x=2) = 6110000/14770000

P(x=2) = 0.4137

P(x=3) = 2544000/14770000

P(x=3) = 0.1722

P(x=4) = 557000/14770000

P(x=4) = 0.0378

The capacities of two trucks are 3 tons and 4 tons respectively. If the smaller truck makes 18 more trips than the larger, it ca

maw [93]

Let's assume

x represent the number of trips that the larger truck makes

so, we are given

If the smaller truck makes 18 more trips than the larger

so,

number of trips for larger truck =x

number of trips for smaller truck =x+18

The capacities of two trucks are 3 tons and 4 tons respectively

so, capacity of smaller truck per trip =3 tons / trip

total ton carried by smaller truck = (number of trips for smaller truck)*(capacity of smaller truck per trip)

now, we can plug values

total ton carried by smaller truck =3*(x+18)

total ton carried by larger truck = (number of trips for larger truck)*(capacity of larger truck per trip)

total ton carried by larger truck =4x

it can deliver 12 more tons of freight than the larger

so, we get

$3(x+18)=4x+12$

we can move 4x on left side

we get

$3(x+18)-4x=12$ ...............Answer

What is the order of operation of 100 + 6² - 9

Kipish [7]

Okay so you would use PEMDAS (parentheses, exponents, multiply, divide, add, and subtract) so there are no parentheses so you do the exponents
${6}^{2} = 36$
then you do the rest so 100+36=136 and then 136-9=127 so the answer is 127
