7/8 time the reciprocal of 11/12 would be 12/11
7/8 times 12/11
7 times 12 is 84 and 11 times 8 is 88
so ur fraction is 84/88
simplify 21/22

The perimeter of the square kitchen floor measures 48 feet. What is the area of the kitchen floor? A. 32 feet B. 96 square feet

exis [7]

Answer:

C. 144 square feet

Step-by-step explanation:

step 1

we know that

The perimeter of a square is given by the formula

$P=4a$

where

P is the perimeter

a is the length side of the square

we have

$p=48\ ft$

substitute in the formula

$48=4a$

solve for a

divide both sides by 4

$a=12\ ft$

step 2

Find the area

The area of a square is given by the formula

$A=a^2$

we have

$a=12\ ft$

substitute

$A=12^2=144\ ft^2$

Question:

An individual is presented with three different glasses of cola, labeled C, D, and P. He is asked to taste all three and then list them in order of preference. Suppose the same cola has actually been put into all three glasses.

(a) What are the simple events in this ranking experiment? (Enter your answers as a comma-separated list.

What probability would you assign to each one?

(b) What is the probability that C is ranked first? (Round your answer to three decimal places.)

Answer:

(a)

Sample Space= {CDP, CPD,DCP,DPC,PCD,PDC}

Probability of each = 1/6

(b)

Probability of C ranking first = 0.333

(c)

Probability of C ranking first and D ranking last = 0.167

Step-by-step explanation:

Let C = Cup 1

Let D = Cup 2

Let P = Cup 3

(a) The possible events

Let SS = Sample Space = The possible outcomes

The possible outcomes are

CDP

CPD

DCP

DPC

PCD

PDC

So, SS = {CDP, CPD,DCP,DPC,PCD,PDC}

Possibly outcome = 6

Probability of each event = number of possible outcomes/Number of Total outcomes

Probability of each event = 1/6

(b)

Probability that C is ranked first

Looking at the sample space (SS), you'll notice that only two events starts with C

The events are CDP and CPD

So the probability = 2/6

Probability = 0.333

(c)

Probability that C ranks first and D ranked last.

Looking at the sample space, you'll notice that only one event satisfies the condition

The event is CPD

So, the probability is 1/6

Probability = 0.167
