Suppose you like to keep a jar of change on your desk. Currently, the jar contains the following: 18 Pennies13 Dimes 18 Nickels13 Quarters What is the probability that you reach into the jar and randomly grab a nickel and then, without replacement, another nickel
Answers
Answer:
[tex]P(Nickel\ and\ Nickel) = 0.08091[/tex]
Step-by-step explanation:
Given
[tex]Pennies = 18[/tex]
[tex]Dimes = 13[/tex]
[tex]Nickels = 18[/tex]
[tex]Quarters = 13[/tex]
Required
Probability of selecting 2 nickels without replacement
This can be represented as: [tex]P(Nickel\ and\ Nickel)[/tex]
The solution is as follows
[tex]P(Nickel\ and\ Nickel) = \frac{Nickel}{Total}*\frac{Nickel-1}{Total-1}[/tex]
The second nickel is reduced by 1 because the first nickel was not replaced and this also reduces the total by 1
So, we have:
[tex]P(Nickel\ and\ Nickel) = \frac{18}{62}*\frac{18-1}{62-1}[/tex]
[tex]P(Nickel\ and\ Nickel) = \frac{18}{62}*\frac{17}{61}[/tex]
[tex]P(Nickel\ and\ Nickel) = \frac{18*17}{62*61}[/tex]
[tex]P(Nickel\ and\ Nickel) = \frac{306}{3782}[/tex]
[tex]P(Nickel\ and\ Nickel) = 0.08091[/tex]

Mary is making a birthday cake to surprise her mom. She needs 3 1/2 cups of flour, but she only has 1/3 cup. How much more flour does she need?
Answers
Answer:
3 1/6 cups more
Step-by-step explanation:
Answer:
3 1/2 = 7/2 (write as a mixed number)
7/2 - 1/3 = ?( you need more flour, so subtract what you have from what you need. to subtract you need to find the least common denominator)
21/6 - 2/6
19/6 cups of flour is what you need.
or 3 1/6 cup if it needs to be converted back into a mixed fraction

Solve the following equation algebraically: 5x2 = 60
a. x~ +3 46
b. x~3.46
c. x = 12
d. X = +12
Answers
Answer:
x = 3.46
Step-by-step explanation:
In this question, you have to solve the equation.
Solve:
5x² = 60
Divide both sides by 5.
x² = 12
In order to eliminate the exponent, you would square root both sides.
√x² = √12
x = √12
√12 = 3.4641..
x = 3.46
Your final answer would be x = 3.46
