Solution:
Ounces of Sugar used by Amanda to make 75 cupcakes = 45 Ounces
As, number of ounces of sugar is in Direct variation with number of cupcakes.
The meaning of direct variation is , the ratio of two variables in each case is same.
Here , Ratio of ounces of sugar, to number of cupcakes in each case will be same.
Let number of ounces of sugar which will be used to make 255 cupcakes be x ounces.
So, Number of ounces of sugar which will be used to make 255 cupcakes = 153 ounces.

Answer:
The population mean is 5 volts
Step-by-step explanation:
Output voltage is assumed to be normally distributed, with standard deviation 0.25 Volts
s=0.25
n = 8
Sample mean = 
Since n < 30 and population standard deviation is unknown
So, we will use t test
Formula : 
t=-1.69
Refer the t table for p value
Degree of freedom = n-1 = 8-1 = 7
So,
P value >α
So, We are failed to reject null hypothesis
Hence The population mean is 5 volts
