Last question of my homework pls <3

dimaraw [331]

Answer:

J(2, 5 )

Step-by-step explanation:

Using the section formula

$x_{J}$ = $\frac{1(-2)+2(4)}{2+1}$ = $\frac{-2+8}{3}$ = $\frac{6}{3}$ = 2

$y_{J}$ = $\frac{1(1)+2(7)}{2+1}$ = $\frac{1+14}{3}$ = $\frac{15}{3}$ = 5

Thus J = (2, 5 )

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:

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

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

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

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

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