Me ! (i am terrible at math)

a public opinion survey is administered to determine how different age groups feel about an increase in the minimum wage. some of the results are shown in the table below.

for - against - no opinion
(21-40 yrs old) 0 20 5
(41-60 yrs old) 20 0 20
(over 60 yrs old) 55 15 5

the survey showed that 40% of the 21 - 40 year-olds surveyed are against an increase, and 15% of the entire sample surveyed has no opinion.

how many 21 - 40 year-olds surveyed are for an increase?

how many 41 - 60 year-olds are against an increase?

How many 21 - 40 year-olds surveyed are for an increase?  

25

How many 41 - 60 year-olds are against an increase?  

35

Step-by-step explanation:

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.
