Answer:
-1
Step-by-step explanation:
Given,
f(x) = -x² + 4x - 1 and x = 0
Putting the value of x we get,
f(0)=
+ (4 X 0) - 1
= -0+0-1
=-1
∴f(x)= -1
So, the required value is -1
Answer: (3, -2)
Step-by-step explanation:
The solution to the system is where the graphs intersect.
Answer:
B. The mean amount of
emitted by the new fuel is actually lower than 89 kg but they fall to conclude it is lower than 89 kg
Step-by-step explanation:
A Type II error is the failure to reject a false null hypothesis.
Given the null and alternate hypothesis of a fuel company which wants to test a new type of gasoline designed to have lower
emissions.:

where
is the mean amount of
emitted by burning one gallon of this new gasoline.
If the null hypothesis is false, then:

A rejection of the alternate hypothesis above will be a Type II error.
Therefore:
The Type II error is: (B) The mean amount of
emitted by the new fuel is actually lower than 89 kg but they fall to conclude it is lower than 89 kg.
