Answer: c. 
Step-by-step explanation:
The confidence interval for population mean is given by :-

, where n= sample size
 = sample mean.
 = sample mean.
z*= Critical value.
 = population standard deviation.
= population standard deviation.
As per given , we have
n= 50

 
 
Also, we know that the critical value for 95% confidence interval : z*= 1.96
Then, the 95% confidence interval (CI) to estimate the true average score of golfers on this particular course will be :
 (substitute all the value in the above formula.)
 (substitute all the value in the above formula.)
Hence, the correct option is c. 
 
        
             
        
        
        
X = number of dimes 
x + 2 = number of nickels
3(x + 2) = number of pennies 
10x + 5(x + 2) + 3(x + 2) = 52
10x + 5x + 10 + 3x + 6 = 52
18x = 36
x = 2
x = 2 (number of dimes)
x + 2 = 4 (number of nickels)
3(x + 2) = 12 (number of pennies)
Check: 
2(10) = 20 cents in dimes
4(5) = 20 cents in nickels
12(1) = 12 cents in pennies
Total = 52 cents

Answer:  144 Joules </h3>
Steps Shown:
Work = Force * Displacement
Work = (36 Newtons)*(4 meters)
Work = (36*4) Newton meters
Work = 144 Newton meters
Work = 144 Joules 
Note: The displacement must point in the same direction as the force applied.
 
        
        
        
Answer:
a. No
b. Yes
c. No
Step-by-step explanation:
a. For BC and B'C to both be parallel to the y-axis when BC is parallel to the y-axis the figure must be rotated by a multiple of 180 degrees.
b. When you rotate a figure none of the angles in the figure change.
c. For D and D' to have the same coordinates the figure must be rotated by 360.
 
        
             
        
        
        
First put the equation in point slope form:
y - 4 = 2x - 6
y = 2x - 2
Then graph this, which will look like this
