Answer: 0.6826894
Step-by-step explanation:
Given : The length of similar components produced by a company are approximated by a normal distribution model with a 5 cm and a 0.02 cm.
Let x be the random variable that represents the length of similar components produced by a company.
z-score :
For x= 4.98
For x= 5.02
By using the standard z-value table (right -tailed) , the probability that the length of this component is between 4.98 and 5.02 will be :_
Hence, the probability that the length of this component is between 4.98 and 5.02= 0.6826894
a right angle is 90°, or 1/4 of a circle.
3/5 * 1/4 = 3/20
radian measure is the length of the circumference of this part of the circle.
a full circumference of a circle would be 2*pi*r, also expressed as 2 rad * r
now let's multiply the full thing with the 3/20 from earlier to just get the desired fraction:
6/20 rad * r
<u>= 3/10 rad * r</u>
of course a solution in cm or inch still depends on the radius here, wich could be just plugged in at will
8.50x+60
that's what I have because you didn't say what the number of hours she worked.
The answer is A.5 because 1/2*4=2. 2+3=5
Answer:
The formula for circumference: 2rpi
PB = r = 29m
The circumference of circle P is:
2(29)pi
=58pi
