Before you can add or subtract fractions, they must have a common denominator.

-- Find a common denominator for [ something/3 ] and [ something/4 ].

-- When you have both of the fractions changed to a common denominator, you can just subtract the second numerator from the first one, and write that difference over the same common denominator.

You have to find the least common denominator, which in this case would be 12.

8/12- 3/12= 5/12

One number is 16 more than another number. The two numbers have a sum of 120. Wbich system of equations could you use to find th

joja [24]

Step-by-step explanation:

Let, 1st number be x and 2nd number be y

Then,

equation 1

x = 16+y

equation 2

x + y = 120

or, y = 120 - x

now,

x = 16 + y

or, x= 16 + 120 - x (putting the value of y from equation 2 )

or, x + x = 136

or, 2x =136

or, x= 136/2

or, x =68

Then,

y = 120-x

or, y= 120- 68 (putting the value of x)

or, y= 52

Hence, the two numbers are 68 and 52.

Can two events with nonzero probabilities be both independent and mutually exclusive? Choose the correct answer below. A. Yes,

Flura [38]

Answer:

Step-by-step explanation:

B. No, two events with nonzero probabilities cannot be independent and mutually exclusive because if two events are mutually exclusive, then when one of them occurs, the probability of the other must be zero.

For two mutually exclusive events , with non- zero probabilities , when one occurs , the other can not happen . In this way they become dependent events . In this way , for two events to be both independent and mutually exclusive , at least one of the two events must have zero probability .
