Answer: Third option is correct.

Step-by-step explanation:

Since we have given that

Transitive property of equality defines that

if a=b, b=c

then, a=c

So, According to question we have

∠A = ∠B and ∠B = ∠C

then ∠A = ∠C

In other options,

For instance, in first option, there is a transposition not transitivity,

in second option and in fourth option , there is just left or right position shift

So, Third option is correct.

madreJ [45]

Given that μ=0, and σ=1, P(z>c)=0.1093
thus
P(z<c)=1-0.1093=0.8907
hence the value of c will be:
z-score=(c-μ)/σ
thus
1.23=(c-0)/1
c=1.23

The waiting times on hold for a call to a customer service department are observed to have the following probability distributio

Elina [12.6K]

Answer:

b. 9.2 minutes

Step-by-step explanation:

To find the expected waiting time for a random call from the sampie given by using the formula:

$\sum (f(X)) = \dfrac{\sum f (x) \times x}{\sum x}$

number of calls (x) waiting time f(x) in minutes f(x) *(x)

0 0 0

2 3 6

4 10 40

6 15 90

8 10 80

10 6 60

$\sum x = 30$ $\sum f(x) *x = 276$

Therefore:

$\sum (f(X)) = \dfrac{276}{30}$

$\sum (f(X)) = 9.2$

Part F What is the mean absolute deviation for Doctor A’s data set on glasses? What is the mean absolute deviation for Doctor B’

frez [133]

There is more variability on glasses of doctor B's dataset than the glasses of doctor A's dataset

<h3>The doctors' mean absolute deviation on glasses</h3>

The dataset of doctor A is given as:

643 634 670 658 636 624 641 655 649 629

The dataset of doctor B is given as:

651 625 622 624 631 621 653 647 646 646

Using a statistical calculator, we have:

<u>Doctor A</u>

Doctor A: Mean Absolute Deviation (MAD) = 11.28
Doctor B: Mean Absolute Deviation (MAD) = 12

Hence, the mean absolute deviation is 11.28 for Doctor A’s and 12 for Doctor B’s data set on glasses

<h3>The variation of the two data</h3>

In a dataset, the larger the mean absolute deviations value, the larger the variation.

By comparison, 12 is greater than 11.28

Hence, there is more variability on glasses of doctor B's dataset than the glasses of doctor A's dataset
