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.

Answer:
tan(45°) = 1
Step-by-step explanation:
We know that sin (45°) = √2/2, and cos(45°) = √2/2.
Given that tan(x) = sen(x) / cos(x), we get:
tan(45°) = (√2/2) / (√2/2) = 1
Therefore, tan(45°) = 1

Answer:
x = ±(√y)/3
x = ±(√2)/3
Step-by-step explanation:
Put the given information in the given equation and solve for x:
f(x) = 2
2 = 9x^2 . . . . . use 2 in place of f(x)
2/9 = x^2 . . . . divide by 9
±√(2/9) = x . . . take the square root
x = ±(√2)/3 . . . simplify
_____
Using this as an example, we can solve f(x) = y in the same way:
y = 9x^2 . . . . use y for f(x)
y/9 = x^2 . . . divide by the coefficient of x^2
±√(y/9) = x . . . take the square root; next, simplify
x = ±(√y)/3 . . . . the equation solved for x. Note this matches the above when y=2.
