There is a chance that you could pick 1/4 with the because how little amout of nickels and 1/2 with dimes and quarters because of there is the same amount of each\
Alenkinab [10]3 years ago

Answer:

There are a total of 10 coins:

Because we have 10 small boxes, all equal, each box has the same probability of being picked.

the coins are:

4 quarters, 4 dimes and 2 nickels.

so 4 boxes have quarters, 4 boxes have dimes, and 2 boxes have nickels.

One way to simulate the experiment can be with a d10 dice, where if you roll it and the numbers are 0,1,2,3 this represents that you took a quarter, if the result is 4, 5, 6, 7 the result is a dime, and if the result is 8 or 9, the result is a nickel.

the problem if the coins are in your pocket is exactly the same because again you have the same distribution of coins and each coin has the same probability of being picked.

F(x) =5x^2-20x+3 how to find minimum
Leya [2.2K]

Answer:

(2,-17) should be the minimum.

Step-by-step explanation:

The minimum of a quadratic function occurs at x=-\frac{b}{2a} . If a is positive, the minimum value of the function is f(-\frac{b}{2a})

f_{min}x=ax^2+bx+c occurs at x=-\frac{b}{2a}

Find the value of x=-\frac{b}{2a}

x = 2

evaluate f(2).

replace the variable x with 2 in the expression.

f(2)=5(2)^2-20(2)+3

simplify the result.

f(2)=5(4)-20(2)+3

f(2)=20-40+3

f(2)=-17

The final answer is -17

Use the x and y values to find where the minimum occurs.

HOPE THIS HELPS!
