A student measures the diameter of a small cylindrical object and gets the following readings: 4.32, 4.35, 4.31, 4.36, 4.37, 4.34 cm. What is the average diameter from these readings?
Answers
Answer:
The average of the diameter readings is 4.34 cm.
Step-by-step explanation:
We are given the following data set(cm):
4.32, 4.35, 4.31, 4.36, 4.37, 4.34
Formula:
Thus, the average of the diameter readings is 4.34 cm.

The problem involves the use of logic and creative thinking. The number of people in the garden is 35.
Given
When you enter the garden, the number of people increases by 1
So, the number of people in the garden is 35.
When 30 people are killed, there are still 35 people.
- 30 dead people
- 5 people alive
Hence, the number of people in the garden is 35.

Answer:
= - 2.43%
Step-by-step explanation:
From the information given:
Since the variable (daily returns) is normally distributed, Then, using empirical rule at 95% confidence interval level, we have:
where;
The expected mean daily return
The standard deviation
Given that the 95% confidence interval is expected to be a maximum loss, then the probability is left-tailed which is 1.65 away from the average.
Thus the distribution of the lower boundary can be computed as:

If you're going to have someone else solve your problem for you, it is much quicker and easier to use an appropriate computer or graphing calculator app. (See the attached.)
9. There are at least a couple of ways to approach this. The law of sines can be used to find the length of another side. Given two sides and the angle between them, a formula gives area.
Law of Sines
... a/sin(A) = c/sin(C)
Multiplying by sin(C) gives
... c = sin(C)·a/sin(A) = 19·sin(64°)/sin(20°) ≈ 49.9301
The angle between sides a and c is B, which has the value ...
... B = 180° -A -C = 180° -20° -64° = 96°
Then the area of the triangle is ...
... Area = (1/2)ac·sin(B) = (1/2)(19)(49.9301)(0.994522) ≈ 471.737 ≈ 471.7
10. Heron's formula will give the area of a triangle from its side lengths.
... s = (a+b+c)/2 = (51+38+45)/2 = 67
... Area = √(s(s-a)(s-b)(s-c)) = √(67·16·29·22) = √683936 ≈ 827.004 ≈ 827.0
