Answer:
17
Step-by-step explanation:
As 2 phones are defective from a group of 98 that were checked, you can determine a percentage:
2/98= 2%
This indicates that 2% of the phones are likely to be defective and because of that you can find 2% of 850:
850*2%= 17
According to this, 17 phones are likely to be defective.
Give the equation 9m = 10n
Dividing both sides by 9n, we have

Therefore, the <span>proportion that results in the equation 9m = 10n is

Answer:
The correct option is Any rational root of f(x) is a factor of 35 divided by a factor of 66....
Step-by-step explanation:
According to the rational root theorem:
if
and
are non zero then each rational solution x will be:
x= +/- Factors of
/ Factors of 
In the given polynomial we have:
66x4 – 2x3 + 11x2 + 35
= 35
= 66
Therefore,
x= +/- Factors of 35/ Factors of 66.
Thus the correct option is Any rational root of f(x) is a factor of 35 divided by a factor of 66....
185/100 + 50/100 +4/100
= (185+50+4)/100
=239/100
=2.39
