Answer:
a) 0.6517; b) 0.9115; c) No
Step-by-step explanation:
For part a, we will use the formula for a z score of an individual:
Using a z table, we see that the area under the curve to the left of this value is 0.3483. However, we want the probability greater than this, which is the area to the right of this value under the curve; this means we subtract from 1:
1-0.3483 = 0.6517
For part b, we will use the formula for a z score of the mean of a sample:
Using a z table, we see that the area under the curve to the left of this value is 0.0885. This means the area under the curve to the right of this value is
1-0.0885 = 0.9115
For part c,
The fact that the probability that any 12 men on the elevator will have a mean weight greater than 167, putting their total weight above 2004 pounds, is 91% means the elevator does not have the appropriate limit. There is a high chance the maximum will be exceeded.
The value of diameter for the given triangle inscribed in a circle will be 22.
<h3>What is a circle?</h3>
A circle is a geometrical figure which becomes by plotting a point around a fixed point by keeping a constant distance.
In our daily life, we always see circular objects for example our bike wheel.
The longest line which can be drawn inside the circle will be the diameter.
As per the given triangle inscribed a circle.
The length x +2 and 2x - 7 will be the radius of the circle and the sides of the triangle will be the tangent of the circle.
x + 2 = 2x - 7
2 = 2x - x - 7
x = 9
Thus, radius = 9 + 2 = 11
Diameter = 11 x 2 = 22 units.
Hence "The value of diameter for the given triangle inscribed in a circle will be 22".

So the sum of 4 times a number (4 times x or 4x) and 7 (+7) is (=) 19 (19)
4x+7=19
subtract 7 from both sdies
4x=12
divide by 4
x=3
the number is 3
