If you mean by completely factored form of x^4y - 4x2y - 5y

Then the answer is y (x^2 - 5) (x^2 + 1)

Answer:

Following are the responses to the given question:

Step-by-step explanation:

$Null \ H_{yp}: \mu_{men} = \mu_{women}\\\\Alt \ Hyp: \mu_{men} \neq \mu_{women}\\\\Std\ Error\ (SE) = \sqrt{(\frac{s_1^2}{n_1}) + (\frac{s_2^2}{n_2})} \\\\$

$= \sqrt{(\frac{0.62}{90}) + (\frac{0.52}{100})} \\\\= 0.08$

$test\ statistic \ t = \frac{(x_1 - x_2)}{SE} = \frac{(8.4 - 8.5)}{0.08} = -1.25$

Degrees of freedom

$= \frac{(\frac{s_1^2}{n_1} + \frac{s_2^2}{n_2})^2}{\frac{(\frac{s_1^2}{n_1})^2}{(n_1 - 1)}} + \frac{(\frac{s_2^2}{n_2)^2}}{(n_2 - 1)} \\\\= 174$

Considering a degree of 5% importance

T for df critical value = 174 and sig level = 0.05 is +1.973

Let area of refusal shall be t < -1.973 or t > +1.973

Because statistical tests weren't in the refusal zone, they may not deny that zero but find that perhaps the argument how both women and men undergo med school is considerably different lengths of time is not significantly supported.

Find the equation for the line that passes through the point (0,-1) and that is perpendicular to the line with the equation (y-3

Alex Ar [27]

I assume you meant (y-3)=(-3/4)(x-1). If so, this line has slope -3/4. A line perpendicular to (y-3)=(-3/4)(x-1) has a slope that is the negative reciprocal of -3/4: That new slope is +4/3.

The new line is thus y - (-1) = (4/3)(x-0), or y + 1 = (4/3)x, or

y = (4/3)x - 1 (answer)
