Answer:
271
Step-by-step explanation:
4 hours and 31 minutes = 240 + 31 = 271 minutes
We have been given that the standard deviation of a group of 20 scores is 15 and we are asked to find variance.
Since we know variance is square of standard deviation. In order to find out the variance of the given data we have to take the square of 15.

Therefore, our variance is 225.
Answer:
To find the slope of two given points, you can use the point-slope formula of (y2 - y1) / (x2 - x1). With the points plugged in, the formula looks like (3 - 2) / (4 - 1). Simplify the formula to get a slope of ⅓.

Answer:
Volume= 27. 12inches³
Step-by-step explanation:
to solve this question lets write out the parameters given
radius of the cylinder = 1.2 inches
height of the cylinder = 6 inches
volume of the cylinder = ?
<u>solution</u>
the fomular to find the volume of a cylinder is given to be
Volume= πr²h
Volume= 3.14 × ( 1.2)² × 6
Volume= 3.14 × 1.44 × 6
Volume= 27. 12inches³
therefore the volume of the cylinder equals to 27. 12inches³
