Answer: ( x -2 ) inches
Step-by-step explanation:
Let x = length of skirt.
Given: Christi first cuts 7 inches off the bottom of the skirt and then adds a 5-inch ruffle to the skirt's remaining bottom edge.
Cutting of length will be represented by a negative integer.
The expression best represents the final length of the skirt = x-7+5 inches
= x -2 inches
Hence, the expression best represents the final length of the skirt = ( x -2 ) inches
Answer:
Interpreting as: (k)=0.
Step-by-step explanation:
The value of P(R = 3) is 0.2854
<h3>Probability</h3>
Probabilities are used to determine the chances of events.
The given parameters are:
- --- the number of slots
- . --- the number of red slot
- . --- the number of black slot
- . --- the number of green slot
<h3>Individual probabilities</h3>
The probability that the ball lands on a red slot is calculated as:
Simplify
The probability that the ball does not land on a red slot is calculated as:
Simplify
<h3>
Binomial probability</h3>
The value of P(R = 3) is then calculated using the following binomial probability formula
Where:
So, we have:
Hence, the value of P(R = 3) is 0.2854
