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).
98% x 40 =
.98 x 40 = 39.2 times out of 40
If she is late 6 times, the claim is inaccurate.

all of the options leave the 3 in its spot so you dont have to worry about that. To get the square root of 56 you just break 56 down until it is left with prim numbers:
56 / 2 =28
Now inside the square root: 2*28
28 / 4=7
Now inside the square root: 2*7*4
4 / 2=2
Now inside the square root: 2*7*2*2
you have two 2's so that comes out of th square root but the a 2 and 7 stays inside, you have to multiply the 2 and 7, giving you a 14.

There are two ways to evaluate the square root of 864: using a calculator, and simplifying the root.
The first method is simplifying the root. While this doesn't give you an exact value, it reduces the number inside the root.
Find the prime factorization of 864:
Take any number that is repeated twice in the square root, and move it outside of the root:
The simplified form of √864 will be 12√6.
The second method is evaluating the root. Using a calculator, we can find the exact value of √864.
Plugged into a calculator and rounded to the nearest hundredths value, √864 is equal to 29.39. Because square roots can be negative or positive when evaluated, this means that √864 is equal to ±29.39.
