Z value is a numerical measurement that describe a value relationship to the mean of a group of values. The standard deviations is 1.25 above the mean is 14,500 hours.
<h3>Given information-</h3>The mean for the bulb is 12,000 hours.
The standard deviation for the bulb is 2000 hours.
Sample value is 14500.
To find out the how many standard deviation is 14500 mean away from the mean the z value of the mean should be calculated.
<h3>Z value</h3>Z value is a numerical measurement that describe a value relationship to the mean of a group of values. Z value is the ratio of the difference of the sample value and mean
to the standard deviation. Thus the z value for the given mean
is,
Thus the standard deviations is 1.25 above the mean is 14,500 hours.

Answer:
a) The radius of the wheel is 1) more than 25.0 cm.
b) The radius of the wheel is approximately 40.925556... cm
Step-by-step explanation:
S = rθ is the formula to find the radius of the wheel using the arc and the angle discovered, S being the arc and θ the angle. The angle, however, must be in radians. θ = is used to convert it. So:
θ =
θ =
S = rθ
25 = r
900 = 7r
r =
r = 40.925556... cm
