The factors of 200 are 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, and 200 .

The factors of 140 are 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, and 140 .

The factors common to both are 1, 2, 4, 5, 10, and 20 .

The greatest one of those is 20 .

Melanie's room measures 10 ft by 12 ft. Her rug covers 90 ft². Explain how to determine the percent of floor covered by the rug.

Inessa [10]

$\huge \bf༆ Answer ༄$

Here's the solution ~

Area of floor is ;

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:10 \times 12$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:120 \: ft {}^{2}$

Area covered by rug is ;

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:90 \: ft {}^{2}$

So, the percentage of floor covered by rug is ~

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \: \dfrac{90}{120} \times 100$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \: \dfrac{3}{4} \times 100$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:3 \times 25$

${ \qquad{ \sf{ \dashrightarrow}}} \: \: \sf \:75 \%$

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

Natalija [7]

Answer: C & D

Step-by-step explanation:

A binomial experiment must satisfy ALL four of the following:

A fixed number of trials
Each trial is independent of the others
There are only two outcomes (Success & Fail)
The probability of each outcome remains constant from trial to trial.

A) When the spinner is spun three times, X is the sum of the numbers the spinner lands on.

→ #3 is not satisfied (#4 is also not satisfied)

B) When the spinner is spun multiple times ...

→ #1 is not satisfied

C) When the spinner is spun four times, X is the number of times the spinner does not land on an odd number.

→ Satisfies ALL FOUR

A fixed number of trials = 4
Each trial is independent of the others = each spin is separate
There are only two outcomes = Not Odd & Odd
The probability of each outcome remains constant from trial to trial = P(X = not odd) = 0.50 for each spin

D) When the spinner is spun five times, X is the number of times the spinner lands on 1.

→ Satisfies ALL FOUR

A fixed number of trials = 5
Each trial is independent of the others = each spin is separate
There are only two outcomes = 1 & Not 1
The probability of each outcome remains constant from trial to trial = P(X = 1) = 0.17 for each spin
