Answer:
9 cups!
Step-by-step explanation:
I cup = 1 liter
? cups = 9 liter
1 * 9 = 9
so ? * 1 = 9
? = 9
6 pennies, 12 nickels, 8 dimes, 4 quarters = 30 coins
a) add the probability for drawing a dime and drawing a quarter together:
12/30 + 4/30 = 16/30 = 8/15
The probability is 8/15 or 53%
b) multiply the probability for drawing a penny and drawing a nickel:
6/30 x 12/30 = 72/900 = 2/25
The probability is 2/25 or 8%
c) multiply the probability for drawing quarters but take away one of the total coins and the amount of quarters each time:
4/30 x 3/29 x 2/28 = 24/24360 = 1/1015
The probability is 1/1015 or 0.099%
Answer:
x - 1
Step-by-step explanation:
To get one factor of the cubic expression x³+3x²+x-5 according to the remainder theorem we can say that
x³+3x²+x-5 = 0
Then we apply Ruffini's Rule and obtain
x³+3x²+x-5 = (x-1)(x²+4x+5)
where x = 1 is the only real root of the polynomial expression.
A and C are equivalent expressions.
