Step-by-step explanation:
We need to write the function that have two real number zeros by calculating the discriminant i.e. 
.
We know that,
If D>0 the roots are real and unequal
If D= 0 roots are real and equal
If D< 0 roots are imaginary or not real and unequal
Function (1)
D>0 the roots are real and unequal
Function (2)
D<0 the roots are real and unequal
Function (3)
D>0 the roots are real and unequal
Function (4)
D>0 the roots are real and unequal
Function (5)
D<0 the roots are real and unequal
Function (6)
D>0 the roots are real and unequal
(1),(3),(4) and (6) have two real number zeroes.
Answer:
277 848 newspapers.
Step-by-step explanation:
Find out how much newspaper he drops for 4.3 miles.
1/4 = 0.25
4.3 miles ÷ 0.25 = 17.2
= 17
17 x 22.7 = 385.9
(Newspapers be dropped a day)
1 week of dropping newspapers = 385.9 x 3 = 1157.7
1 month of dropping newspapers = 1157.7 x 4 =
4630.8
1 year = 12 months
5 years = 12 x 5 = 60 months.
5 years/60 months of dropping newspapers = 4630.8 x 60 = 277 848
Tommy dropped 277 848 newspapers.
Answer:
d. Both have the same chance because they are both random samples.
