Answer:

See explanation

Step-by-step explanation:

1. Given the expression

$\dfrac{\sqrt[7]{x^5} }{\sqrt[4]{x^2} }$

Note that

$\sqrt[7]{x^5}=x^{\frac{5}{7}} \\ \\\sqrt[4]{x^2}=x^{\frac{2}{4}}=x^{\frac{1}{2}}$

When dividing $\sqrt[7]{x^5}$ by $\sqrt[4]{x^2},$ we have to subtract powers (we cannot subtract 4 from 7, because then we get another expression), so

$\dfrac{5}{7}-\dfrac{2}{4}=\dfrac{5}{7}-\dfrac{1}{2}=\dfrac{5\cdot 2-1\cdot 7}{14}=\dfrac{3}{14}$

and the result is $x^{\frac{3}{14}}=\sqrt[14]{x^3}$

2. Given equation $3\sqrt[4]{(x-2)^3} -4=20$

Add 4:

$3\sqrt[4]{(x-2)^3} -4+4=20+4\\ \\3\sqrt[4]{(x-2)^3}=24$

Divide by 3:

$\sqrt[4]{(x-2)^3} =8$

Rewrite the equation as:

$(x-2)^{\frac{3}{4}}=8\\ \\(x-2)^{\frac{3}{4}}=2^3$

Hence,

$\left((x-2)^{\frac{3}{4}}\right)^{\frac{4}{3}}=(2^3)^{\frac{4}{3}}\\ \\x-2=2^{3\cdot \frac{4}{3}}\\ \\x-2=2^4\\ \\x-2=16\\ \\x-2+2=16+2\\ \\x=18$

How to solve it and answer

Arlecino [84]

Hi there!

»»————-　★　————-««

I believe your answer is:

Scatterplot B

»»————-　★　————-««

Here’s why:

A scatterplot with a correlation coefficient of 0 would show no relationship between the variables at all. It will not form any line at any strength.
Scatterplot B best resembles this. Notice how the plots do not resemble a line; they are just 'scattered' all over.

The sum of three numbers is 101. The second number is 4 more than two times the first number. The third number is 5 less than th

dem82 [27]

Answer:

Step-by-step explanation:

Given

Let the first number = x

Let the second number = 2x + 4

Let the third number = 3x -5

The sum of the three numbers = 101

Equation

x + 2x + 4 + 3x - 5 = 101 Combine like terms on the left

x + 2x + 3x + 4 - 5 = 101 Combine

6x - 1 = 101 Add 1 to both sides

6x = 101 + 1

6x = 102 Divide by 6

6x/6 = 102/6

x = 17

Answer

The first number = 17

The second number = 2*17 + 4 = 34 + 4 = 38

The Third number = 3*17 - 5 = 51 - 5 = 46

Check

17 + 38 + 46 = 101
