To solve this problem, we make use of the z statistic. The formula for the z score is:z score = (x – u) / swhere x is the sample value = 0.90, u is the sample mean = 0.917, and s is the standard deviation = 0.005
Therefore:z score = (0.90 – 0.917) / 0.005z score = -3.4
From the standard probability tables, the p-value for a right tailed test of z = -3.4 is:P = 0.9997
Therefore there is a 99.97% chance that it will be above 0.90 mm
Answer:
The area of the sector (shaded section) is 29.51 
.
Step-by-step explanation:
Area of a sector = (θ ÷ 360) 
where θ is the central angle of the sector, and r is the radius of the circle.
From the diagram give, diameter of the circle is 26 m. So that;
r = 
= 
= 13 m
θ = 360 - (180 + 160)
= 360 - 340
= 
Thus,
area of the given sector = 
x 
x 
= x x x 169
= 29.5079
The area of the sector (shaded section) is 29.51 .
12/372= 31 is the answer.
When an event is independent of the other, it means Event A does not influence Event B.
For example, if one was to find the probability of someone owning a car and what there neighbour eats, there is no correlation. In this situation, the events are independent.
Hope I helped :)
