Simplify: [(6x^3 y^-4)^-2] / [(3x^2 y^5)^-3] (The / is the fraction line)

Vera_Pavlovna [14]

$\bf \cfrac{(6x^3y^{-4})^{-2}}{(3x^2y^5)^{-3}}\implies \stackrel{\textit{using positive exponents}}{\cfrac{(3x^2y^5)^3}{(6x^3y^{-4})^2}}\implies \stackrel{\textit{distributing the exponent}}{\cfrac{(3^3x^{2\cdot 3}y^{5\cdot 3})}{(6^2x^{3\cdot 2}y^{-4\cdot 2})}} \\\\\\ \cfrac{27x^6y^{15}}{36x^6y^{-8}}\implies \cfrac{27}{36}\cdot \cfrac{x^6y^{15}}{x^6y^{-8}}\implies \cfrac{3}{4}\cdot x^6x^{-6}y^{15}y^8\implies \cfrac{3}{4}\cdot x^{6-6}y^{15+8} \\\\\\ \cfrac{3}{4}\cdot 1y^{23}\implies \cfrac{3y^{23}}{4}$

What is the five number summary for this data set?

MrRa [10]

Answer:

see explanation

Step-by-step explanation:

The median is the middle value of the data set in ascending order. If there is no exact middle then the median is the average of the values either side of the middle.

Given

3 8 14 19 22 29 33 37 43 49

↑ middle is between 22 and 29

median = $\frac{22+29}{2}$ = $\frac{51}{2}$ = 25.5

The upper quartile $Q_{3}$ is the middle value of the data to the right of the median.

29 33 37 43 49

↑

$Q_{3}$ = 37

The lower quartile $Q_{1}$ is the middle value of the data to the left of the median.

3 8 14 19 22

↑

$Q_{1}$ = 14

The min is the smallest value in the data set, that is 3

The max is the largest value in the data set, that is 49

The 5 number summary is

3, 14, 25.5, 37, 49

Select the ordered pair that is the solution of this equation: -7x – 4y = 6

Olegator [25]

Its just a matter of subbing

-7x - 4y = 6....subbing in (-2,2)...x = -2 and y = 2
-7(-2) - 4(2) = 6
14 - 8 = 6
6 = 6 (correct)

so ur solution is (-2,2)

Which of the following is a solution of x2 + 5x = −2? (2 points) 5 plus or minus the square root of 33 divided by two. 5 plus or

Delicious77 [7]

The easiest way it to solve it.
${x}^{2} + 5x + 2 = 0$
You have
$\rho = 25 - 4 \times 1 \times 2 = 17$
Thus
$x = \frac{ - 5 \pm \sqrt{17} }{2}$

One card is randomly selected from a deck of cards. find the odds against drawing a blackblack fivefive.

neonofarm [45]

Since there are 2 black suites and there are 26 (1/2) black cards in a deck, and there is 1 five per suite, there are 2 black fives. Therefore, since there are 52 cards in a deck, there is a 2/52 you draw a black 5. To find the odds against that, we get 1-2/52=52/52-2/52=50/52 due to that we want to find the probability of not drawing a black 5 so we subtract the chances of getting that from the equation
