Answer:

a. The empirical rule.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed(bell-shaped) random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

So the correct answer is:

a. The empirical rule.

Use Ohm’s law to find the resistance of the light bulb if you had a 20 volt battery and 0.57 amps of current. Show your work for
aleksley [76]
For this case we have the following equation:
 V = I * R
 Where,
 V: voltage
 I: current
 R: resistance
 By clearing R we have:
 R = V / I
 Substituting the values:
 R = (20) / (0.57)
 R = 35.09 Ohms
 Answer:
 
The resistance of the light bulb is:
 
R = 35.09 Ohms

omeli [17]
There are several information's of immense importance in the problem. Based on these information's the answer to the question can be easily reached. The only thing that has to be kept in mind is the calculation part, otherwise it is a simple problem.
Now it is given that:
A large chocolate shake takes 8/9 of a pint of milk.
Then
Amount of milk required to make medium shake = (8/9) * (1/7) of a pint
                                                                              = 8/63 of a pint
Then it can be said that for making a medium chocolate shake , 8/63 of a pint of milk is required. This is the simplest form of the fraction and it cannot be expressed as a mixed number since the denominator is higher than the numerator.
