Answer:
0.6710
Step-by-step explanation:
The diameters of ball bearings are distributed normally. The mean diameter is 107 millimeters and the population standard deviation is 5 millimeters.
Find the probability that the diameter of a selected bearing is between 104 and 115 millimeters. Round your answer to four decimal places.
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score
μ is the population mean = 107 mm
σ is the population standard deviation = 5 mm
For x = 104 mm
z = 104 - 107/5
z = -0.6
Probability value from Z-Table:
P(x = 104) = 0.27425
For x = 115 mm
z = 115 - 107/5
z = 1.6
Probability value from Z-Table:
P(x = 115) = 0.9452
The probability that the diameter of a selected bearing is between 104 and 115 millimeters is calculated as:
P(x = 115) - P(x = 104)
0.9452 - 0.27425
= 0.67095
Approximately = 0.6710

<h3>
Answer:</h3>
8/13
<h3>
Step-by-step explanation:</h3>
Given in the question
Ratio of sandwiches white bread to brown bread is 10 : 3
white bread fraction = 10/13
brown bread fraction = 3/13
It is also provided that
2/3 white are vegetarian
1/2 brown are vegetarian
So
for white bread vegetables sandwich we will find 2/3 of 10
20/3/13
for brown bread vegetable sandwich we will find 1/2 of 3
3/2/13
adding both
20/3/13 + 3/2/13
8/13 (approximate)
