Bryant collects a set of 20 data representing the lengths of worms he found in the garden. The variance of the set of measurements is 36.What is the standard deviation from the mean

Answers

Answer 1

Answer: Given:
data set : 20 numbers
variance : 36

Find the standard deviation from the mean.

If the variance is already provided, we simply find the square root of the variance to get the standard deviation.

Standard deviation = √36 = 6

Answer 2

Answer:

The standard deviation of the data from the mean is √variance, which is: 6.

What is Standard Deviation?

The standard deviation can be gotten by finding the square root of the variance of the data. That is, Standard deviation = √variance.

Given the following:

Variance = 36

Standard deviation = √36

Standard deviation from the mean = 6

Fill in the blank. In the triangle below, z = _____.

Answers

Well, for any triangle the angles inside of it will add up to 180...
So the square in the corner of the triangle means its a right angle, meaning its 90 degrees.
If we add 90 and 42 together that equals 132.
180 minus 132 equals 48.
This meaning that angle z is 48 degrees.

Answer: z = 48 degrees

In the triangle given, the missing angle z = 48°

What is the sum of angles in a right-angle triangle?

The sum of angles in a right-angle triangle is 180°. To calculate a missing angle in the right angle triangle, we have to sum up the given angles and equate it to 180°.

From the given information, we have:

90° + 42° + z = 180°

132° + z = 180°

z = 180° - 132°

z = 48°

Therefore, we can conclude that the missing angle z = 48°
