Using the data in the table, which statement is true?

horsena [70]

Answer: Choice C. mean > median

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

Explanation:

Multiply each measure with their corresponding frequency.

8*1 = 8
10*3 = 30
14*2 = 28

Add up those products: 8+30+28 = 66

Then divide by the total frequency n = 1+3+2 = 6 to get 66/6 = 11 as the mean.

mean = 11

----------------

Since we have n = 6 values in this list, this means the median is between slot n/2 = 6/2 = 3 and slot 4.

Note how that places us in the middle row because 1+3 = 4 encapsulates both of those slots mentioned. So the median is 10.

Or you could list out the values in roster notation {8, 10, 10, 10, 14, 14} to see that {10,10} occupy the middle most slots. So the median is (10+10)/2 = 20/2 = 10.

median = 10

-----------------

The mode is simply the most frequent value. The table shows that mode = 10 since it occurs 3 times, compared to 8 showing up 1 time and 14 showing up twice.

-----------------

We have the following summary

mean = 11
median = 10
mode = 10

With that in mind, let's go through the answer choices.

We can see that mean < mode is false, since it should be mean > median, so cross choice A off the list.
mean = median is also false, so choice B is crossed off as well.
mean > median is true since 11 > 10 is true. Choice C is the answer. Note how this being true directly contradicts choice B, which is another reason to see why choice B is false.
median > mode is false because 10 > 10 is false. It should be median = mode. Choice D is crossed off the list.

When 500 pesos is compounded monthly at 4% interest rate fo 3 years, what is the frequency of conversion?

Dimas [21]

Answer:

The answer is "562.432"

Step-by-step explanation:

Given:

$P= 500\\\\r= 4\%\\\\n= 3 \ years\\\\\text{frequency of conversion}\ (A)=?$

Using formula:

$\to A=P(1+r)^n$

$= 500(1+4\%)^3\\\\= 500(1+\frac{4}{100})^3\\\\= 500(1.04)^3\\\\=500 \times 1.124864\\\\= 562.432$

Please help me wit dis no one would help and i really need help

(4) 64 tiles, (5) $\mathrm{N}=\mathrm{s}^{2}$ , (6) $N^{2}=S^{4}$

Step-by-step explanation:

Given data: Side length of square tile = 1 ft

(4) Side length of square pool = 8 ft

$\text {Number of tiles} =\frac{\text { Area of square pool }}{\text { area of square tile }}$

$=\frac{8 \times 8}{1 \times 1}$

= 64

Hence 64 tiles needed for the border.

(5) Suppose number of square tiles be N and side of square tub is s ft.

So, N = $\frac{s \times s}{1 \times 1}$

$\Rightarrow N=s^{2}$

So, the expression is $\mathrm{N}=\mathrm{s}^{2}$ .

(6) The equivalent expression is $\mathrm{N}^{2}=\mathrm{S}^{4}$ .

How to solve this problem?

valentinak56 [21]

Very nice handwriting but the math and English are confusing.

Let's assume we're told

$\displaystyle 45 = \sum_{i=1}^9 (x_i - 10)^2$

The subscript is important.

I think we're told the similar sum with 11 gives the smallest possible value for the sum. This is a rather cagey way of telling us 11 is the mean of the nine points. The mean is the number which minimizes the sum of squared deviations.

$\displaystyle 45 = \sum_{i=1}^9 (x_i - 10)^2 = \sum x_i^2 - 20 \sum x_i + 9(100)$

$\displaystyle \sum x_i^2= 20 \sum x_i - 900$

If 11 is the mean, the sum of the points is 9(11)=99.

$\displaystyle \sum x_i^2= 20 (99) - 900 = 1080$

Answer: 1080
