Answers

Answer 1
Answer:

Answer:

P(k)=0.2628

Step-by-step explanation:

Given

n = 1693 --- sample size

k = 445 --- those that prefer chocolate ice cream to vanilla

Required

P(k)

This is calculated as:

P(k)=(k)/(n) --- probability formula

So, we have:

P(k)=(445)/(1693)

P(k)=0.2628

Answers

Answer:

Explanation:

1260/180 = n - 2
7 = n - 2
7 + 2 = n
9 = n

Therefore, n = 9

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:

Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}

Mean =\displaystyle(26.05)/(6) = 4.34167 \approx 4.34

Thus, the average of the diameter readings is 4.34 cm.
