(2, 1)
Step-by-step explanation:
We have the following system of equations
To solve the system, substitute the second equation in the first equation and solve for the variable x
Now substitute the value of x into any of the two equations and solve for the variable y.
Finally the system of equations has one solution

Answer:
95 nickels 19 dimes
Step-by-step explanation:
d=dimes
5d=nickels
0.05(5d) + 0.10(d) = 6.65
0.25d + 0.10d = 6.65
0.35d=6.65
Divide by 0.35
d= 19 (19 coins)
19 dimes =$1.9
6.65-1.9= $4.75
Nickels=$4.75
4.75/0.05 = 95 coins
19*5=95
114 coins in total
19*0.10 = 1.9
95*0.05=4.74
4.75+1.9= 6.65
Answer:
0.0000
Step-by-step explanation:
The sign test can be defined as a statistical method which can be used to test for consistent differences that are in existence between pairs
Now If N is 4, Preal is 0.80 in the predicted direction, and this is a 0.05 1-tail. Using the sign test, the power is going to be 0.0000.
The Answer is :
power = 0.0000
