Answer: -2
Explanation: The coefficient is the number to the left of the variable.
Another example would be that 10xy has the coefficient 10.
Something like x^2 has coefficient 1 because x^2 = 1x^2.
Answer:
Step-by-step explanation:
Given that the mean salary for a new teacher in your town is $48,000
You believe it is higher for new teachers in a neighboring town.
So to prove or disprove your claim you have to show statistical evidence.
For that hypothesis testing is necessary.
You must conduct a hypothesis test for comparing the mean of salary of new teacher with neighbouring places
The hypotheses wouldbe

where mu is the average for neighbouring states.
Answer:
16 times
Step-by-step explanation:

If only the radius is changed, the change in volume will be proportionate to the multiplicative factor squared.

Therefore, if the cone is quadrupled (multiplied by 4), the volume of the larger cone will be 4² times greater than the volume of the smaller cone, so <u>16 times greater </u>than the smaller cone.
<h3><u>Proof</u></h3>
Given:
Substituting the given values into the formula:

If the radius is quadrupled:
- radius = 6 × 4 = 24
- height = 9
Substituting the new given values into the formula:

To find the number of times greater the volume of the large cone is than the volume of the smaller cone, divide their volumes:

So the volume of the larger cone is <u>16 times greater</u> than the volume of the smaller cone.
Answer:
0.05
Step-by-step explanation:
2 does not move 5 up, but 5 moves 4 up to 5, thus making it 0.05.
