Answer:

The correct answer would be C.

Step-by-step explanation:

{(1, 2); (2, 2); (3, 2); (4, 2)}

A function doesn't let its x-coordinates repeat.  In the first option, 2 repeats.  In the second option, 1 repeats.  In the 4th option, 1 repeats.

Hope this helps! :)

The owner of a sporting goods store in Phoenix, Arizona surveys her customers to determine the proportion of customers that play
BabaBlast [244]

Answer:

C

Step-by-step explanation:

This is a sample proportion where p^ represents the sample proportion.

If we have p^ = 0.6, it means about 60% of the sample are in agreement with or significant to the case study.

The case study here is 'customers that play racquetball' and p^ was 0.16.

This means that 16% of the customers of the sample said they play racquetball.

Please help i need answer and explanation.
allsm [11]

Answer:

m<TVZ = 95

Step-by-step explanation:

2x+15+2x+5= 180

4x+20 =180

     -20  -20

4x=160

x= 40

2x+15= m<TVZ

2(40)+15 = m<TVZ

80+15 = m<TVZ

95 = m<TVZ

To check:

2x+5= <WVZ

2(40)+5 = <WVZ

80+5 = <WZV

85+95 = 180

The two angles together should equal 180. Comment if you have any questions :)
