telo118 [61]

Answer:

Step-by-step explanation:

Probability is the likelihood or chance that an event will occur.

Probability = number of expected outcome/total outcome.

a)Total number of student is the total outcome = 40

Expected number of outcome is the number of students who bought 20 or more books = 6 (number of students who bought 20-24 books)

Probability of those students who bought 20 or more books = 6/40 = 0.15

Expressing as percentage = 0.15 * 100 = 15%

This means that 15% of the total students bought 20 or more books

b) Mean is calculated using the formula $\overline x =\frac{\sum fx}{N}$

f is the frequency

x is the midpoint of the class interval

N is the total number of students.

Check the attachment for the frequency table.

$\overline x = \frac{410}{40}\\ \overline x = 10.25$

Mean number of books bought is 10.25

Alice, Bryan and Cindy share the cost of renting an apartment in the ratio

never [62]

Answer: $3510

Step-by-step explanation:

Fro th question, Alice, Bryan and Cindy share the cost of renting an apartment in the ratio 3:6:4 respectively and we.are informed that Alice pays $810 monthly.

Alice ratio = 3

Bryan's ratio = 6

Cindy's ratio = 4

Total ratio = 3+6+4 = 13

Since Alice has a ratio of 3, this means that Alice pays 3/13 of the total monthly rent. Let the total rent be x. Therefore,

3/13 of x = 810

3/13 × x = 810

3x/13 = 810

3x = 810 × 13

3x = 10530

x = 10530/3

x = 3510

Therefore, the monthly rent is $3510
