Answer:

1. Mean: 10 Median: 11 Mode: 13

2. Mean: 26.7 Median: 20.5 Mode: 20

Step-by-step explanation:

1. Mean: 6+7+11+13+13 = 50 then, 50/5 = 10

Median: 6, 7, 11, 13, 13 in the middle: 11

6- crossed

13- crossed

7- crossed

13- crossed

That leaves 11!

Mode: 13 appears two times. All the other numbers only appear once.

2. Mean: 0+20+20+30+40+70 = 160 then, 160/6 = 26.7 ( rounded to nearest tenth)

Median: 0, 20, 20, 30, 40, 70

0- crossed

70- crossed

20- crossed

40- crossed

20- crossed

30- crossed

They all are crossed, but the last 2 to be crossed are 20 and 30. The middle of those two numbers is 20.5 therefore, the median is 20.5!

Mode: 20 appears twice while the rest only appears once.

I hope this helps, good luck! :)

An individual who has automobile insurance from a certain company is randomly selected. Let Y be the number of mov- ing violatio

olga2289 [7]

Answer:

a) $E(Y) = \sum_{i=1}^n Y_i P(Y_i)$

And replacing we got:

$E(Y) =0*0.60 +1*0.25 +2*0.1 +3*0.05 = 0.60$

b) $E(Y^2) =0^2*0.60 +1^2*0.25 +2^2*0.1 +3^2*0.05 = 1.1$

And then the expected value would be:

$E(100Y^2) = 100*1.1= 110$

Step-by-step explanation:

We assume the following distribution given:

Y 0 1 2 3

P(Y) 0.60 0.25 0.10 0.05

Part a

We can find the expected value with this formula:

$E(Y) = \sum_{i=1}^n Y_i P(Y_i)$

And replacing we got:

$E(Y) =0*0.60 +1*0.25 +2*0.1 +3*0.05 = 0.60$

Part b

If we want to find the expected value of $100 Y^2$ we need to find the expected value of Y^2 and we have:

$E(Y^2) = \sum_{i=1}^n Y^2_i P(Y_i)$

And replacing we got:

$E(Y^2) =0^2*0.60 +1^2*0.25 +2^2*0.1 +3^2*0.05 = 1.1$

And then the expected value would be:

$E(100Y^2) = 100*1.1= 110$

Evaluate (3.5×10^13)-(1.4×10^12)/3×10^9

maw [93]

Answer:

11,200

Step-by-step explanation:

At first we use "BODMAS" rule.

Given,

(3.5×10^13)-(1.4×10^12)/3×10^9

So, we will break the brackets at first. With the help of excel, we can get the desired result. The following images will show you the step-by-step result.

Use "Number" instead of "general" in the excel sheet. You can use calculator too.
