ANSWERS

$\frac{19}{20}$

EXPLANATION

It was given that triangle LMN is a right triangle and angle L and M are complementary.

This implies that:

$\sin(L) = \cos(M)$

It was given in the question that:

$\cos(M) = \frac{19}{20}$

This implies that:

$\sin(L) = \frac{19}{20}$

0.43.

Step-by-step explanation:

The probability that the customer will pay with debit card = 50%

The percentage of customers who use coupons 30% and 35% pay with debit card.

Now calculate the probability that the same person will use coupon:

P[Uses coupons | Pays with Debit card] = P[Uses coupons and pays with debit card] / P[ Pays with debit card]

= 0.3 * 0.5 / 0.35

= 3/7 or 0.4286 or 42.86%
