Answer:

second option

Step-by-step explanation:

five times a number: 5n (five times 2 = 5*2 = 10 like that)

four less than five times a number: 5n - 4

its like saying 7 less than 14. You take 7 away from 14 (14-7), not 7-14.

The whole thing equals to 11

Hence: 5n - 4 = 11 and n would equal 3

Answer:

5x - 4 = 11

Step-by-step explanation:

4 less than 5 times a number equals 11

5 times a number minus 4 equals 11

(5*x) - 4 = 11

I hope this helps!!!

Consider randomly selecting a student at a large university. Let A be the event that the selected student has a Visa card, let B
wariber [46]

Answer:

a. 0.76

b. 0.23

c. 0.5

d. p(B/A) is the probability that given that a student has a visa card, they also have a master card

p(A/B) is the probability that given a student has a master card, they also have a visa card

e. 0.35

f. 0.31

Step-by-step explanation:

a. p(AUBUC)= P(A)+P(B)+P(C)-P(AnB)-P(AnC)-P(BnC)+P(AnBnC)

                    =0.6+0.4+0.2-0.3-0.11-0.1+0.07= 0.76

b. P(AnBnC')= P(AnB)-P(AnBnC)

                    =0.3-0.07= 0.23

c. P(B/A)= P(AnB)/P(A)

             =0.3/O.6= 0.5

e. P((AnB)/C))= P((AnB)nC)/P(C)

                     =P(AnBnC)/P(C)

                     =0.07/0.2= 0.35

f. P((AUB)/C)= P((AUB)nC)/P(C)

                    =(P(AnC) U P(BnC))/P(C)

                     =(0.11+0.1)/0.2

                     =0.21/0.2 = 0.31

Is the number a rational number? Help me out please!
krek1111 [17]

Answer:

first answer

Step-by-step explanation:

Hi, this is correct because repeating decimals are rational numbers.

Rational numbers can be written by a fraction of integers.

If there is a pattern, it means that this is the division of two integers.

hope this helps

It will just keep going on as a decimal so you do not need to keep going, three spaces after the decimal should be an acceptable answer.
