Answer:
4
Step-by-step explanation:
3x2=6
6 times what gives 24?
6x4=24
So x=4
Step-by-step explanation:
-2x³ + 14x² + 120x
= -2x(x² - 7x - 60)
= -2x(x - 12)(x + 5).
The other 2 dimensions are -2x and (x + 5).
When using a graphing calculator to maximise the volume of the prism, we get x = 7.378. However this value is not reasonable as it makes -2x and (x - 12) negative, which are the sides of the prism.
19 - 2 = 17 17 - 4 = 13 number = 13
Answer:
The reuired probability is 0.756
Step-by-step explanation:
Let the number of trucks be 'N'
1) Trucks on interstate highway N'= 76% of N =0.76N
2) Truck on intra-state highway N''= 24% of N = 0.24N
i) Number of trucks flagged on intrastate highway = 3.4% of N'' = 
ii) Number of trucks flagged on interstate highway = 0.7% of N' = 
Part a)
The probability that the truck is an interstate truck and is not flagged for safety is 
where
is the probability that the truck chosen is on interstate
is the probability that the truck chosen on interstate is flagged
