Answer:-3
Step-by-step explanation:
4^2=16, 1^3=1, (-3)^2=9
so
16-1+3=18/(3-9)
so 18/-6= -3
Answer:
$1.90 approx
Step-by-step explanation:
Given data
Amount paid= $74.94
Amount of gallons= 201/5 gallons of gas
= 201/5
=40.2 gallons
let us find the unit cost per gallons
Unit cost per gallon is = 74.94/40.2
Unit cost per gallon=$1.86
The price of gas is $1.90 approx
Answer:
6.8 x 12.5 x 13 = 1105
Step-by-step explanation:
Start by multiplying 3 times 3x to get 9x. Then multiply 3 times -6 to get -18
After that your equation is 18=9x-18
Then your going to add 18 to each side so your equation should be 36=9x
Then devide each side by 9 so the answer will be x=4
Answer : Probability that the pumping system will fail on any given day = 0.005
Explanation:
Probability that only older pump fail = P(A) = 0.10
Probability that only newer pump fail = P(B) = 0.05
Since they are independent events ,
then the conditions will be
P(A∩B) = P(A). P(B)
= 0.10 ×0.05
= 0.005
Hence, the probability will fail on any given day = 0.005
