Answer:

Mean: 33.454545 Median: 34.5 Mode: 25

Step-by-step explanation:

By putting all of the numbers in numerical order, then adding them and dividing them by 11 (the number of numbers in the list), you get 33.45 repeating as the mean. With the organized list of numbers find the middle number, which is 35, and that is the median. The mode, the most common number in the sequence, is 37 and 25.

25+25+27+28+32+35+37+37+39+41+42=368

368/11=33.45454545

Which mean absolute value represents more consistency 15.2 or 10.9
pychu [463]

Given :

Two mean absolute value deviation 15.2 and 10.9 .

To Find :

Which mean absolute value deviation represents more consistency 15.2 or 10.9 .

Solution :

First we should know what is mean absolute deviation ( M.A.D) is :

M.A.D of a data set is the average distance between each data value and the mean .

It also describe the variation in a data set .

Also , high variability means the data is spread out and low variability means that data is clustered .

So, low variation means more consistency and vice-versa .

Therefore , 10.9 M.A.D is more consistent .

Hence , this is the required solution .

Choose the explanation that shows why ΔADE is similar to ΔABC.
Natasha2012 [34]

Recall that a dilation with center (0, 0) and scale factor k maps (x,y) onto (kx, ky).

Now, triangle ADE is formed by

A=(0,0),\quad D=(0,2),\quad E=(4,0)

Whereas triangle ABC is formed by

A=(0,0),\quad B=(0,4),\quad C=(8,0)

In other words, the coordinates of B and C can be obtained by multiplying by 2 the coordinates of D and E.

This means that you get ABC from ADE by dilating with center (0,0) and scale factor 2.

Suppose you invest $16000 at 9% interest and that it is compounded daily. How much will you have in 8 years?
kramer

Answer:

The amount after 8 years is $ 16,031.579

Step-by-step explanation:

Given as :

The Principal invested = $ 16000

The rate of interest compounded daily = 9 %

The time period = 8 years

Let The amount after 8 years = $ A

<u>From Compounded method </u>

Amount = Principal invested × (1+\dfrac{\textrm Rate}{365\times 100})^{365\times \textrm Time}

Or, Amount = 16000 × (1+\dfrac{\textrm 9}{365\times 100})^{365\times \textrm 8}

Or, Amount = 16000 × (1.0002465)^{8}

∴  Amount = $ 16,031.579

Hence The amount after 8 years is $ 16,031.579   Answer
