-2.54 is equal to -2 27/50
Answer:
Part a) 
Part b) 
Step-by-step explanation:
we have
60 rev/min
Part a) Find the angular speed in radians per minute
we know that
One revolution represent 2π radians (complete circle)
so

To convert rev to rad, multiply by 2π

Part b) Find the linear speed in inches per minute
we know that
The circumference of a circle is equal to

we have
----> given problem
substitute


Remember that
One revolution subtends a length equal to the circumference of the circle
so

To convert rev to in, multiply by 16π

Answer:
The correct option is c which is if this test was one-tailed instead of two-tailed, you would reject the null.
Step-by-step explanation:
a: This statement cannot be true as the p-value for a 1 tailed test is dependent on the level of significance and other features.
b: This statement cannot be true as there is no valid mathematical correlation between the p-value of the one-tailed test and the current p-value.
c: This statement is true because due to the enhanced level of significance, the null hypothesis will not be rejected.
d: This statement is inverse of statement c which cannot be true.
e: The statement cannot be true as there is no correlation between the current p-value and the p-value of 1 tailed test. The correlation exists between the values of one-tailed and two-tailed p-values.
I am assuming x is the same thing as b.
−7.5(x−3)=3.75
-7.5x+22.5=3.75
-7.5x=-18.75
x=2.5
