AB and EDC are parallel lines.
ohaa [14]

Answer:

x = 125°, y = 55°, z = 70°

Step-by-step explanation:

x and 55 are adjacent angles and are supplementary, sum to 180°, that is

x + 55° = 180° ( subtract 55° from both sides )

x = 125°

∠ ABD and ∠ BDC are alternate angles and congruent , so

y = 55°

Since BD and BC are congruent, then Δ BCD is isosceles, so

∠ BDC = ∠ BCD = 55° and

z = 180° - (55 + 55)° ← angle sum of triangle

   = 180° - 110°

   = 70°

A university investigation was conducted to determine whether women and men complete medical school in significantly different a
Rudiy27

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.
