Suppose you like to keep a jar of change on your desk. Currently, the jar contains the following: 18 Pennies13 Dimes 18 Nickels1

Nezavi [6.7K]

Answer:

$P(Nickel\ and\ Nickel) = 0.08091$

Step-by-step explanation:

Given

$Pennies = 18$

$Dimes = 13$

$Nickels = 18$

$Quarters = 13$

Required

Probability of selecting 2 nickels without replacement

This can be represented as: $P(Nickel\ and\ Nickel)$

The solution is as follows

$P(Nickel\ and\ Nickel) = \frac{Nickel}{Total}*\frac{Nickel-1}{Total-1}$

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:

$P(Nickel\ and\ Nickel) = \frac{18}{62}*\frac{18-1}{62-1}$

$P(Nickel\ and\ Nickel) = \frac{18}{62}*\frac{17}{61}$

$P(Nickel\ and\ Nickel) = \frac{18*17}{62*61}$

$P(Nickel\ and\ Nickel) = \frac{306}{3782}$

$P(Nickel\ and\ Nickel) = 0.08091$

A composite figure is formed from a cone and a cylinder with the same base radius, and its volume can be calculated by multiplyi

olga55 [171]

The composite figure comprises of a cone balanced on top of cylinder

Step-by-step explanation:

The composite figure is formed from a cone and a cylinder with the same base radius, Let the base radius be r

Then the volume of the cone will be $V_{cone}$

Then the volume of the cylinder will be $V_{cylinder}$

$V_{cylinder} = \pi r^{2} h_{cylinder}$

The total volume of the composite figure will be V, where

$V= V_{cone} + V_{cylinder}$

$V = \frac{1}{3} \pi r^{2} h_{cone} +\pi r^{2} h_{cylinder}$

let the height of cone and cylinder be same

The volume of the composite figure will be $\frac{4}{3} \pi r$ $r^{2} h$

Hence $\frac{4}{3} = \frac{a}{b}$

Thecomposite figure comprises of a cone balanced on top of cylinder

mojhsa [17]

Answer:

C

Any time you have a subtraction and a negitive right next to eachother, it means to add. So, you would add 13 and 1 to get 14, then keep the denominator 19 to get 14/19.
