If a graph fails the vertical line test it's not a function; you can't have a single x map to two ys.
Vice versa, if the graph passes the verticle line test, it's a function.
The horizontal line test tests for injectivity aka one-to-one-ness; it has no bearing on whether something's a function.
Answer:
no
Step-by-step explanation:
if it was a factor then, 2-3x = 0
x= 2/3
putting x = 2/3 in eqn,
(2/3)^2 - 2/3 +1 =7/9....so it is not a factor
Answer:
I think it is 0.257 kg
Step-by-step explanation:
To change units from the gram to kilogram, you need to divide by 1000, because 1kg=1000g:
257÷1000= 0.257 Kg
Answer:
16.9°
Step-by-step explanation:
tan x = 1.7/5.6
tan^-1 x = 16.9°
Answer:
P(A and B) is greater than 1 is never happened ⇒ C
Step-by-step explanation:
Two events are independent if the result of the second event is not affected by the result of the first event
If A and B are independent events, the probability of both events is the product of the probabilities of the both events P (A and B) = P(A) · P(B)
∵ The probability of any event is less than 1
∵ P(A) < 1
∵ P(A) > 
- That means P(A) is greater than half and less than 1
∴
< P(A) < 1
∵ P(B) < 1
∵ P(B) > 
- That means P(B) is greater than half and less than 1
∴
< P(B) < 1
∵ P(A and B) = P(A) . P(B)
- Remember the product of any fractions less than 1 is less than 1
∴
< P(A) . P(B) < 1
- That means any expression equals to P(A) . P(B) must be greater
than
and less than 1
∴
< P(A and B) < 1
∴ P(A and B) is greater than 1 is never happened
