Is this True or False ?
Svetradugi [14.3K]

Answer:

Option B True

Step-by-step explanation:

we know that

A function relates <u>each element</u> of a set  (input) with <u>exactly one</u> element of another set  (output)

1) "...each element..." means that every element in X (input)  is related to some element in Y (output)

2) "...exactly one..." means that a function is single valued. It will not give back 2 or more results for the same input

therefore

Jisoo drank 3/8 of a quart of chocolate milk, and his friend Andrew drank 2/7 of the same quart. How much did they drink altoget
elixir [45]

Answer:

37/56

Step-by-step explanation:

If Jisoo drank 3/8 of a quart of chocolate milk, and his friend Andrew drank 2/7 of the same quart, the amount they drank altogether will be the sum of the amount they drank individually

Total = 3/8 + 2/7

Find the LCM

Total = 3(7)+8(2)/56

Total = (21+16)/56

Total = 37/56

Hence they drank 37/56 of the quartz altogether
