Question
What is the height of the shape formed by the sectors shown below? A circle is cut into 8 equal sections. The sections are arranged into the shape of a parallelogram with a base of pi r and height of question mark.
a. r
b. d
c. pi times r
d Pi times d
Answer:
a. r
Step-by-step explanation:
In the diagram shown, we can see the sections are divided into 8 and each has a radius of r
The 8 sections from the circle is used to form the a parallelogram.
If we take a look at the diagram of the parallelogram closely, we can see definitely that it still showing the divided 8 equal sections using to form it.
Hence, the height of the parallelogram = the radius of the circle.
Therefore, height of the shape formed by the sectors is r
Answer:
d. 0.3446
Step-by-step explanation:
We need to calculate the z-score for the given weekly income.
We calculate the z-score of $1000 using the formula
From the question, the standard deviation is dollars.
The average weekly income is dollars.
Let us substitute these values into the formula to obtain:
We now read from the standard normal distribution table the area that corresponds to a z-score of -0.4.
From the standard normal distribution table, .
We round to 4 decimal places to obtain: .
Therefore the probability that a trainee earns less than $1,000 a week is .
The correct choice is D.
