Answer:

4 2/3 divided by 7. You can do 14/3 by making it an improper fraction. Then you can do 14/3 divided by 7/1.

(LCR) 14/3 * 1/7 = 14/21.

Simplify by 7.

14 divided by 7 is 2.

21 divided by 7 is 3.

The answer is 2/3!

A restaurant offers 6 choices of appetizer, 8 choices of a main meal, and 5 choices of dessert. A customer can choose to eat jus

Katen [24]

Answer:

377 choices

Step-by-step explanation:

From the above question, we are told that

A restaurant offers 6 choices of appetizer, 8 choices of main meal and 5 choices of dessert. A customer can choose to eat just one course, or two different courses, or all three courses.

Let us represent each choice by :

A = Appetizer = 6

M = Main meal = 8

D = Dessert = 5

a) The combination of the 3 choices together

AMD=6 × 8 × 5=240

b) AM= Appetizer and Main meal

= 6 × 8 = 48

c) AD= Appetizer and Dessert

= 6 × 5 = 30

d) MD = Main meal × Dessert

= 8 × 5 = 40

e) A,M,D (each alone)=

Appetizer + Main meal + Dessert

= 6 + 8 + 5

= 19

Assuming all choices are available, how many different possible meals does the restaurant offer?

This is calculated as:

AMD + AM + AD + MD + A,M,D

240 + 48 + 30 + 40 + 19

= 377 choices

The probability that Fiona wakes up before 8am when she does not set her alarm is 2/5 On two consecutive days that Fiona does no

denpristay [2]

Answer:

16/25 = 0.64 = 64%

Step-by-step explanation:

If we want the probability of Fiona waking up before 8am for at least one of the days, we can calculate the probability of she not waking up 8am in both days, and then we do 1 minus this probability.

The probability of she not waking up 8am in one day is (1 - 2/5) = 3/5

The probability of she not waking up 8am in both days is 3/5 * 3/5 = 9/25

So, the probability of Fiona waking up before 8am for at least one of the days is (1 - 9/25) = 16/25 = 0.64 = 64%

Ed and Taylor work together on a group quiz that has 20 multiple-choice questions, each with four choices for the possible answe

MissTica

Answer:

a. p = 0.25

b. n = 10, p = 0.25.

c. n = 10, p = 0.25.

d. n = 20, p = 0.25.

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

a. For any single question on the quiz, what is p = chance of a correct guess?

4 options, 1 of which is correct. So

$p = \frac{1}{4} = 0.25$

So p = 0.25.

b. Let X = number of correct guesses that Isabelle makes. What are the values of n and p for the binomial distribution that describes X?

Should be Ed here.

Ed guesses answers for the first 10 questions

This means that $n = 10$ .

p is the same, so n = 10, p = 0.25.

c. Let Y = number of correct guesses that Taylor makes. What are the values of n and p for the binomial distribution that describes Y?

10 question, so $n = 10$ , p is the same.

d. Consider X + Y = total correct guesses that Isabelle and Taylor make. What are the values of n and p for the binomial distribution that describes X + Y?

20 questions, so $n = 20$

10 for Ed, with 0.25 probability, 10 for Taylor, with 0.25 probability. So

$p = \frac{10}{20}*0.25 + \frac{10}{20}*0.25 = 0.125 + 0.125 = 0.25$

So n = 20, p = 0.25.
