Answer:
A) True : Confidence Interval is the interval range around sample statistic, which is certain by extent of confidence level, to consist the actual population parameter.
B) True : Confidence Interval is the interval range around sample statistic, which is certain by extent of confidence level, to consist the actual population parameter.
C) False : Null Hypothesis can be accepted, despite of being actually false. This is called Type 2 Error.

Hope this helps:)
It will make a right triangle with base angle of 60 degree
cos60=12/D
where D=distance how much belt travel
1/2=12/D
1/2*12=D
d=6 feet
hope am right
If you split a circle in to 4, and color in 3 of the 4 pieces you will find that 3/4 are bigger than 2/3
Answer:
Step-by-step explanation:
If we subtract 3 from the unknown number, we get just as much as if we subtracted 7 from the unknown number and we multiplied the result by 2
The given quadratic function is:

The zeros of the quadratic functions also known as its roots can be found using the quadratic formula.
According to the quadratic formula:

here,
b = coefficient of x-term
a = coefficient of x²-term
c = costant term
For given function:
a = 2
b = 8
c = - 3
Using these values in the formula, we get:

Thus, these values of x are the zeros of the given quadratic function f(x)=2x²+8x-3
