If you randomly choose two letters from the word "JANUARY ", find the probability that you choose letter J first and then A after replacing the first. Round answer to nearest tenth and include percent sign. Also, does this represent an independent or dependent scenario?

2.0%

Step-by-step explanation:

The probability of two events happening in the sequence is calculated by multiplying the probability of each event happening separately by one another. Since there are a total of 7 letters in this word then the probability of choosing one letter correctly is . Since the first letter is replaced before choosing the second letter the probability remains the same. Therefore, the sequence would be the following...

= 0.020164 or 2.0%

This is an independent scenario because it does not depend on any external factors and under these circumstances the percentage will remain the same.

the answer is a

step-by-step explanation:

because your just changing the position of where the shape is

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
