If a fourth plant produces 150 widgets in 60
days, which statement is true?

the complete question in the attached figure

the statements are

1) It makes less than plant B

2) It makes the same as plant A

3) It makes more than plant C

we know that

analyzing the graph

plant A

for x=40  y=100

for x=50   y=200

that means 

the production in 10 days is 100 widgets

then

the production in 60 days will be 6*100> 600 widgets

so

plant A production  > plant fourth production

plant fourth production < plant A production

plant B

for x=40  y=0

for x=60   y=100

that means 

the production in 20 days is 100 widgets

then

the production in 60 days will be 3*100> 300 widgets

so

plant B production  < plant fourth production

plant fourth production > plant B production

plant C

for x=20  y=0

for x=40   y=100

that means 

the production in 20 days is 100 widgets

then

the production in 60 days will be 3*100> 300 widgets

plant C production  < plant fourth production

or 

plant fourth production > plant C production

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
