We need to find driver'side time. We will start by using formula for speed and solve for time.
Speed(S)=distance (d)/time (t) and S=178.9mph d=900 miles
S=d/t
(t)S=(d/t)(t)
tS=d
tS/S=d/S
t=d/St
t=900miles/178.9mph
t=5.03hrs

the probability of the event choosing a yellow marble is 2/9 .

<u>Step-by-step explanation:</u>

Here we have , to choose a marble from a jar. The jar contains 4 red

marbles, 10 blue marbles, 7 green marbles, and 6 yellow marbles. We need to Find the probability of the event choosing a yellow marble . Let's find out:

Yellow marbles = 6

Now , Probability to chose a yellow marble is :

Favorable outcomes = 6(Number of yellow marbles )

Total outcomes = 4+10+7+6 = 27( Total marbles )

Hence ,

⇒ $Probability = \frac{6}{27}$

⇒ $Probability = \frac{2}{9}$

Therefore , the probability of the event choosing a yellow marble is 2/9 .

Vlad [161]

Answer:

Ben has mixed up the digit for millions and hundred thousands: he wrote 5 in the place for millions and 6 in the place for hundred thousands, but it should be the other way. I think that he should exchange those two digits in the faulty report.
