Answer:

$\frac{9x}{y^3}$

Step-by-step explanation:

$\frac{\left(3x^2y^4\right)^3}{3x^5y^{15}}$

$(3x^2y^4)^3 : 3^3x^6y^1^2$

= $\frac{3^3x^6y^{12}}{3x^5y^{15}}$

$\frac{3^{3} }{2} = 3^{2}$

= $\frac{3^2x^6y^{12}}{x^5y^{15}}$

= $\frac{x^{6} }{x^{5} } : x$

= $\frac{3^2xy^{12}}{y^{15}}$

= $\frac{y^{12} }{y^{15} } : \frac{1}{3{y} }$

= $\frac{3^2x}{y^3}$

$3^2=9$

= $\frac{9x}{y^3}$

Helpppp please can somebody please explain this to me.

katen-ka-za [31]

Answer:

this is simple once you get the hang of it!! as you see in the chart they gave you, 1=3.15, meaning you graph it (1, 3.15) and so on. all you do is multiply each number (for example, 4) times 3.15 and (4x3.15=6). so 3.15 times all the x-axis numbers and graph it (x, y).. hope this makes sense :)

Which of the following is true for a median? Medians are affected by outliers. Medians can be calculated no matter how the data

Lady bird [3.3K]

Answer:

Option D) is true about median

Step-by-step explanation:

We are given the following information in the question:

Median:

The median is the middle number or the center of the data when the data is sorted in either ascending or descending order.

The median is not affected by the presence of any outliers since the data is sorted.

$Median:\\\text{If n is odd, then}\\\\Median = \displaystyle\frac{n+1}{2}th ~term \\\\\text{If n is even, then}\\\\Median = \displaystyle\frac{\frac{n}{2}th~term + (\frac{n}{2}+1)th~term}{2}$

Option A) Medians are not affected by the outliers

Option B) Medians can only be calculated when the data is sorted.

Option C) This is a false statement about the medians.

Option D) True

When there are even number of observations, the median is the mean of the two middle numbers.

What is the measure of Q?

SVETLANKA909090 [29]

Answer:

<Q = 30

Step-by-step explanation:

2x + 70 + x - 10 = 180

3x + 60 = 180

3x = 120

x = 40

x - 10

40 - 10

<Q = 30 because of vertical angles
