A function cannot send one input to more than one distinct output. You can think of this as passing the vertical line test – if you can draw a vertical line which passes through more than one point in a graph, it does not represent a function.

a. Not a function (there are several values of x that are sent to more than one value of y)

b. Not a function (-1 is sent to two different values of y)

c. Function (each value of x is sent to exactly one value of y)

d. Function (though 2 is listed as an input twice, the y-value is the same both times, so it is not sent to two different outputs)

e. Not a function (7 is sent to more than one different value)

Point X lies on plane S and on plane R. True or false?
Naya [18.7K]

The answer is true.

Point X lies on the line of intersection of planes S and R. This means that point X lies on both plane S and plane R at the same time.

You could also try and imagine the diagram without plane S and see that point X lies on plane R. Then you can imagine the same diagram without plane R and see that point X lies on plane S.

Let me know if you need any clarifications, thanks!

Oksi-84 [34.3K]

Answer:

P( ace) = 1/13

P (< 5) = 3/13

Step-by-step explanation:

There are 4 Aces in a deck of cards, 1 in each suit

P (ace) = number of aces/ total cards

           = 4/52 = 1/13

Numbers less than 5: 4 twos, 4 threes, 4  fours =12 cards less than 5 ( since we do not include aces)   There are 4 of each card since there is one in each suit.

P ( card < 5) = cards less than 5/ total

                     =12/52 = 3/13
