Answer:
The null hypothesis is 
The alternate hypothesis is 
Step-by-step explanation:
The diameter of a spindle in a small motor is supposed to be 4.1 millimeters
This means that the null hypothesis is that the diameter has the supposed value, that is,
If the spindle is either too small or too large, the motor will not work properly. The manufacturer measures the diameter in a sample of 41 spindles to determine whether the mean diameter has moved away from the required measurement.
Tests if it has moved away, that is, if the mean is different from the specified value of 4.1. So the alternate hypothesis is

Answer:
The edge lengths are 3 for all of them. Radical cubed 27 is also 3.
Step-by-step explanation:
27/ 3 = 9. The square root of 9 is 3. So 3 * 3 * 3 = 27. For the bottom answer, it is 3 since 3 * 3 * 3 = 27.
How simple is this answer. I don't understand your problem.
Answer:
The answer to your question is: the third option is correct 6√5 / 5
Step-by-step explanation:
6 / √5
6 x √5 = 6√5
√5 x √5 5
or 6√5 / 5
X ft tall: 11 ft shadow
7 ft tall: 2 ft shadow
11÷2= 5.5, 2×5.5=11 so 7×5.5= x
x= 38.5 ft tall
The utility pole is 38.5 ft tall.
