A light rail service claims to be on time 98% of the time.Jeanette takes the light rail 40 times in one month how many times can she predict she will be on time is the light rails claim accurate if she is late 6 times

Answers

Answer:

Jeanette would be on time on 85% of her trips.

Step-by-step explanation:

If the light rail service claims to be on time 98% of the time, it should arrive on time at least 39 of 40 times, as 40 x 98 / 100 is equal to 39.2. In consequence, as Jeanette's service arrived late in 6 of over 40 times, we can affirm that what the light rail stated was incorrect. A delayed service in 6 of 40 times has a punctuality rate of 85%, since 6 is the 15% of 40 (40 x 15 / 100 = 40).

If the claim is accurate she should be on time

98% x 40 =
.98 x 40 = 39.2 times out of 40

If she is late 6 times, the claim is inaccurate.

I need help with this answer

Answers

So if you make them improper fractions the -2 1/2 would turn into -5/2 and the 3 1/2 would turn into 7/2. If you do a multiplicative inverse to the 7/2 that makes the equation
-5/2 x 2/7
-5 x 2= -10
2 x 7=14
So you would have -10/14
You can simplify -10/14 into -5/7 and that’s your answer
