15. She bought:

3 jeans, $20 each

1 pants, $18

You find the total: 3(20) + 1(18) = $78 then you apply the discount

Since this is between 50-100, you use the 38% discount (decimal form: 0.38)

38% is being subtracted from your total, so you can do this:

100% - 38% = 62% This is your total after the discount

78(0.62) = 48.36 Your answer is C

A coin is being flipped 400 times. What is the probability of it landing on heads at most 170 times, rounded to the nearest tent

lisabon 2012 [21]

Hello!

We have two probabilities we can use; we have 170/400, for our experiment, and 1/2, which is our theoretical probability.

To solve, we just multiply the two probabilities.

$\frac{170}{400}(1/2)$ =0.2125≈21.3

Therefore, we have about a 21.3% chance of this event occurring.

I hope this helps!
