Answer:

A.

Step-by-step explanation:

Here is an example of an inverse statement for future reference:

Inverse: -p → -q

If not p, then not q.

Yanka [14]

Answer:

Range=14

\sigma^2 =32.4

\sigma = 5 .7

The standard deviation will remain unchanged.

Step-by-step explanation:

Given

Data: 136, 129, 141, 139, 138, 127

Solving (a): The range

This is calculated as:

Range = Highest - Least

Where:

Highest = 141; Least = 127

So:

Range=141-127

Range=14

Solving (b): The variance

First, we calculate the mean

\bar x = \frac{1}{n} \sum x

\bar x = \frac{1}{6} (136+ 129+ 141+ 139+ 138+ 127)

\bar x = \frac{1}{6} *810

\bar x = 135

The variance is calculated as:

\sigma^2 =\frac{1}{n-1}\sum(x - \bar x)^2

So, we have:

\sigma^2 =\frac{1}{6-1}*[(136 - 135)^2 +(129 - 135)^2 +(141 - 135)^2 +(139 - 135)^2 +(138 - 135)^2 +(127 - 135)^2]

\sigma^2 =\frac{1}{5}*[162]

\sigma^2 =32.4

Solving (c): The standard deviation

This is calculated as:

\sigma = \sqrt {\sigma^2 }

\sigma = \sqrt {32.4}

\sigma = 5 .7 --- approximately

Solving (d): With the stated condition, the standard deviation will remain unchanged.

Classify the sequences as arithmetic geometric, Fibonacci -5,0,10,15,25
vovikov84 [41]

It is arithmetic.

It starts at - 5,

the next item is 0 then 5 and next is 15 ...

============

It isn't geometric. You  are not  multiplying by 5

The second term  must be and not- 5 * 5 = - 25

============

A Fibonacci series adds the previous two terms together to get the next term

Usually it starts at 0, but it doesn't need to.

0,1,1,2,3,5,8,13,21,34 ....
