The first thing we should know is the value of each currency:
nickels = 0.05 $
dimes = 0.1 $
Let
x: number of nickels
y: number of dimes
We write the system of equations:
0.05x + 0.1y = 6.30
x + y = 100
To find the solution, you can graph both lines. The intersection between both lines is the number of nickels and dimes.
answer
Graph both lines in the same Cartesian plane and see where they intersect.
Answer:
t = 1.15 seconds.
Step-by-step explanation:
The pumpkin is dropped from the height of = 64 feet.
Now we have to find the time taken to reach the pumpkin on ground. Use the below formula to find the time taken.
H = ½ gt^2
H = height
g = 9.8 (always contant )
t = time taken.
Now insert all the values in the formula.
H = ½ gt^2
64 = ½ ×9.8× t^2
(64×2) / 9.8 = t^2
t = 1.15 seconds.

The parameter used in the probability is the average number of students represented by u.
How to calculate the probability?
The confidence interval based on the information will be:
= 3.85 - 2.09(1.348 / ✓20)
= 3.22
Also, 3.85 + 2.09(1.348 / ✓20) = 4.48
The confidence interval simply means that one is 95% confident that the true mean is between 3.22 and 4.48.
