Hello!

An outlier can cause the mean to be misleading. If you have an outlier when finding the median or IQR, it will not throw off the data by much. But adding a very large or small number to the mean, and dividing it by an extra number, it will throw the number off by a large amount.

I hope this helps!

Answer:

The value of x will be:

$x=22\sqrt{2}$

$x = 31.1$

Step-by-step explanation:

Given

a = 22

b = 22

To determine

hypotenuse x = ?

For a right-angled triangle with sides, a and b the hypotenuse c is defined as

$c=\sqrt{a^2+b^2}$

substituting a = 22, b = 22 and c = x

$x=\sqrt{22^2+22^2}$

$x=\sqrt{22^2\cdot \:2}$

Apply radical rule: $\sqrt[n]{ab}=\sqrt[n]{a}\sqrt[n]{b},\:\quad \mathrm{\:assuming\:}a\ge 0,\:b\ge 0$

$x=\sqrt{2}\sqrt{22^2}$

$x=22\sqrt{2}$

$x = 31.1$

Therefore, the value of x will be:

$x=22\sqrt{2}$

$x = 31.1$

If k represents a number, then write an expression for the ratio of 3 less than k to 2 more than k

Svetradugi [14.3K]

Answer:

k - 3 : k + 2

Step-by-step explanation:

3 less than k = k - 3

2 more than k = k + 2

Ratio of 3 less than k to 2 more than k

In ratios, the word 'to' is represented as a colon :

k - 3 : k + 2

Hope this helps :)

Answer:

Part A:

What We Need to Find is How Much money He Made over the summer

Setting Up the Problem We Would Do 160 + 180 Because we are trying to figure how Much money he made over the summer.

160 + 180 = 340

So Javonie Made 340$ over the Summer

Part B:

Determine what you need to fine?

We trying to figure Out How Much he charged per dog?

To Set up this Problem We are going to Divide 160 Divided By 8

and 180 divided by 9

160 Divided by 8 is 20 In July

180 divided by 9 is 20

so the Answer Is Javonie Charged 20$ per dog in July.

Answer: <em>"7 is a solution to the original equation. The value –1 is an extraneous solution."</em>

Step-by-step explanation:

The equation $x=\sqrt{6x+7}$ can be solved by squaring both sides:

$x^2 = 6x + 7\\\\x^2 - 6x - 7 = 0\\\\(x-7)(x+1) = 0$

We can see that -1 and 7 are solutions, but make sure they are not extraneous by substituting them in the original equation:

$1 = \sqrt{-1}\\ 7 = \sqrt{49}$

The square root of 49 equals 7, but the square root of -1 is an imaginary number.

The correct choice is <em>"7 is a solution to the original equation. The value –1 is an extraneous solution."</em>
