Answer:
$0.0646 is the expected value of the draw.
Step-by-step explanation:
1 nickel = 5 cents
1 dime = 10 cents
1 penny = 1 cent
Total number of coins = 
Probability that a nickel is selected is = 14/35
Probability that a dime is selected is = 15/35
Probability that a penny is selected is = 6/35
So, the expected value of the draw will be =

= 6.457 cents ≈6.46 cents
So, in dollars it is =
= $0.0646
So, $0.0646 is the expected value of the draw.
Answer: Formula= x^2 - 2x - 8
Roots=(-2 , 0) (4 , 0)
Step-by-step explanation:
1.) find the equation (the formula is Ax^2 + Bx + C, so plug it in)
2.)Plug it into your calculator's Y= X^2 - 2X - 8 (if you have one)
3.)Press 2nd, Calc, 2
4.)Go to the X Intersect , it will say Left Bound at the bottom left corner
5.)Press the left arrow about 3 or 4 times, hit enter
6.) It will now say Right Bound in the same corner go back to the X intersect, now press the right arrow 3 or 4 times
Repeat steps 3 to 6 for the other X intersect.
Answer:
The x-intercept of this equation is at the point (0,0).
Step-by-step explanation:
The graph starts at the origin because the log of 4^0 = 0.
I graphed the equation on the graph below to show you how I got my answer.
