C. you have a deficit of 1000
Explanation:
We say that we have a surplus when the net income is more than the total expenses, while we say that we have a deficit when the net income is less than the total expenses.
In this case, the net income is 1500, which is less than the total expenses (2500): so, we have a deficit. In order to calculate the deficit, we can use the formula
deficit = total expenses - net income
Substituting the data of the problem, we find
deficit = 2500 - 1500 = 1000
 
        
                    
             
        
        
        
Answer:
a) Standard error = 0.5
b) 99% Confidence interval:  (19.2125,21.7875)
Step-by-step explanation:
We are given the following in the question:
Population mean =  20.50 mpg
Sample standard deviation = 3.00 mpg
Sample size , n = 36
Standard Error = 

99% Confidence interval:

Putting the values, we get,


 
        
             
        
        
        
In a race, a bicyclist travels 3/4 of a mile in 1/4 hour. Determine the unit rate for the speed in miles per hour.
5/2 miles per hour
(3/4÷1/4)=3 miles per hour☆☆☆☆☆☆☆
41/4 miles per hour
4 miles per hour

Answer:
easy-peasy
Step-by-step explanation:
Perimeter: 
P=2(a+b)
P=2(50+70)
P=2(120
P=240
Area:
A=50*70
A=3,500
