Answer:

We can expect 28 defected cars.

Step-by-step explanation:

Let us assume that the defected cars are "uniformly distributed" in the total set of cars.

Then we can write the proportion 8%2F360 = x%2F1260 for the unknown amount x of defected cars among 1260 cars.

Solving the proportion for x you get

x = 8%2A1260%2F360 = 8%2A3.5 = 28.

Marysya12 [62]

Answer

Let t be number of minutes since tap is opened

water is increased by 20 gallons of water per minute.

sugar increase rate of 3 pounds per minute

water :- W(t) = 350 + 10 t

sugar :- S(t) = 10 + 3 t

concentration

C(t) = $\dfrac{S(t)}{W(t)}$

at t = 15 minutes

C(15) = $\dfrac{S(15)}{W(15)}$

C(15) = $\dfrac{10 + 3\times 15 }{350 + 10\times 15}$

C(15) = 0.11

at beginning t = 0 minutes

C(0) = $\dfrac{S(0)}{W(0)}$

C(0) = $\dfrac{10 + 3\times 0}{350 + 10\times 0}$

C(0) = 0.0286

C(15) > C(0)

hence, concentration is increasing as time is passing.

Assume that cost is 2 times more important than reputation and reputation is 3 times more important than compatibility with exis

dusya [7]

Let the weightage of Ease of Use be x
Ease of Use = x

Compatibility is 5 times more than ease of use:
Compatibility = 5x

Reputation is 3 times more important than compatibility:
Reputation = 3(5x)
Reputation = 15x

Cost is 2 times more important than reputation:
Cost = 2(15x)
Cost = 30x

So the weightage are:
Ease of Use : 1
Compatibility : 5
Reputation :15
Cost : 30
