The data consists of 25 observations - this is just how many people were involved in the study. (count the rows, excluding the header)

As for number of variables, that depends on the aim of the study. More likely than not, I suspect the name of each person involved is irrelevant, which leaves 7 variables. (count the columns, excluding the first)

A university is building a new student center that is two- thirds the distance from the arts center to the residential complex.

Natasha2012 [34]

Answer:

$C = (\frac{21}{5},\frac{33}{5})$

Step-by-step explanation:

Given

Points: (1, 9) and (9, 3)

Ratio = 2/3

Required

Determine the coordinate of the center

Represent the ratio as ratio

$Ratio = 2:3$

The new coordinate can be calculated using

$C = (\frac{mx_2 + nx_1}{n + m},\frac{my_2 + ny_1}{n + m})$

Where

$(x_1,y_1) = (1, 9)$

$(x_2, y_2) = (9, 3)$

$m:n = 2:3$

Substitute these values in the equation above

$C = (\frac{2 * 9 + 3 * 1}{3 + 2},\frac{2 * 3 + 3 * 9}{2 + 3})$

$C = (\frac{18 + 3}{5},\frac{6 + 27}{5})$

$C = (\frac{21}{5},\frac{33}{5})$

Hence;

<em>The coordinates of the new center is </em> $C = (\frac{21}{5},\frac{33}{5})$ <em></em>

Common factors of 8xy⁴,6x²y,10x²y²

Citrus2011 [14]

Answer:

$2^{3}$ ×5×3× $x^{2}$ × $y^{4}$

Step-by-step explanation:

$8xy^{4}$ = $2^{3}$ × $x$ × $y^{4}$

6 $x^{2} y$ = 2×3× $x^{2}$ × $y^{}$

10 $x^{2} y^{2}$ = 2×5× $x^{2}$ × $y^{2}$

$2^{3}$ ×5×3× $x^{2}$ × $y^{4}$
