<h3>Hey there! </h3><h3>The word/ phrase "standard deviation" <u>means the measure of how to spread out the numbers are </u></h3><h3>So, </h3><h3> $52,$ $61,$ $31,$ $44,$ $47,$ $45,$ $25,$ $48,$ $47$ standard deviation is/are most likely: $\boxed{10.701765171119}$ ← $\boxed{answer}$ </h3><h3>In order for you to find out the standard deviation of this particular problem (or problems of standard deviation) you had <u>to work out for the mean,</u> meaning to simplify the averages of each and every number, then you would have to<u> subtract your mean and your square for the outcome </u> Nextly, <u>workout your mean for those squared for your differences..</u> Lastly <u>take whatever your square of that number and keep it as your result/ outcome </u></h3><h3>Good luck on your assignment and enjoy your day! </h3><h3>~ $LoveYourselfFirst:)$ </h3>

Martha estimated there were 86 marbles in a jar for a contest. The actual number of marbles in the jar was 107. What was the

jekas [21]

Answer:

Roughly 20.4%

Step-by-step explanation:

Use the formula of percent of error:

| Actual number - Guess / Actual number | (100)

The actual number is 108 and the guessed number is 86:

| 108 - 86 / 108 | (100)

= | 22/108 | (100)

= | 0.2037037037 | (100)

The vertical lines indicate absolute value. This means that anything inside of it must be turned into its positive form. Since it is already positive, just take the signs away:

0.2037037037(100)

≈ 0.204(100)

= 20.4

Turn this into a percent:

20.4%

Martha's percent of error is 20.4%

Please tell me if I was right or not. I really hope this helps!
