The cost of Ms. Clark's restaurant meal is $25.50.
lapo4ka [179]

Answer: The correct answer is B.

Step-by-step explanation: We are given the cost of restaurant meal of M. Clark is $25.50.

and she has given 20% of the meal's cost as a tip to the waiter.

Step 1: Calculating the amount of tip paid

\text{amount of tip}=\frac{20}{100}\times 25.50

Total tip paid = $5.1

Step 2: To find the total amount, we add the cost of the meal and the tip paid

Total amount = Cost of the meal + Tip paid

Total amount = $25.50 + $5.10

Total amount paid by Ms. Clark = $30.6

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!
Nadya [2.5K]

Answer: b) rolled three times, number of 2s rolled

              d) rolled twice, number of odds rolled

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

A binomial experiment must meet the following criteria:

  1. There must be a fixed number of trials (rolls)
  2. Each trial (roll) is independent of the others
  3. There are only two outcomes (success or fail)
  4. The probability of each outcome remains constant from trial to trial

a) rolled twice --> satisfies #1 & #2 (n = 2)

   X is the sum --> fails #3 (more than two outcomes)

b) rolled three times --> satisfies #1 & #2 (n = 3)

   X is the number of 2s rolled --> satisfies #3 & #4 (P success = 1/6)

c) rolled an unknown number of times - fails #1

d) rolled twice --> satisfies #1 & #2 (n = 2)

   X is the number of odds rolled --> satisfies #3 & #4 (P success = 1/2)
