Answer:

a) P) 0.25 = 1/4 both

b) P) 0.75 = 3/4 one

c) P) 0.25 = 1/4 none

Step-by-step explanation:

4 routes to D + H

6 routes to H + S

= D H S

4 | 6

- 2 | -3

= 2 | 3 = route 1 = 2/4 and route 2 = 3/6

= 1/2 route 1 and 1/2 route 2

Answer a ) = 1/2 x 1/2 = 0.25 = 1/4 = 0.25 probability

Answer b) = 1- (1/2 x 1/2) = 1- 0.25 = 3/4 = 0.75 probability

Answer c) = 1/2 x 1/2 = 0.25 = 1/4 = 0.25 probability

A class student council election was held on Monday and 15 of the 20 students decided to vote. On Tuesday, another election was

Umnica [9.8K]

In this problem you cross multiple. So on Monday 15 out 20 students vote which is 15/20 and the second one is 16 students present and we don’t know how many people voted which is x/16 so we multiple 20 by x and 16 by 15 we get 20x=240 we need to isolate x so we divide 20 on both sides and x=12

Lines x and y intersect to make two pairs of vertical angles, q, s and r, t. Fill in the blank space in the given proof to prove

bonufazy [111]

Answer:

C) Subtraction property of equality.

Step-by-step explanation:

Given that, two lines $x$ and $y$ intersect to make pairs of vertical angles:

$\angle q, \angle s$ and $\angle r, \angle t$ .

Kindly refer to the attached image for details of the given angles and lines.

Proof that $\angle q\cong \angle s$ :

$\begin{center}\begin{tabular}{ c c}Statements & Reasons \\ m\angle q+m\angle r=180^\circ & \angle q\ and\ \angle r\ are\ supplementary \\ m\angle r+m\angle s=180^\circ & \angle r\ and\ \angle s\ are\ supplementary \\ \angle q+\angle r=\angle q+\angle r & Algebraic substitution \\ m\angle q = m\angle s & Subtraction property of equality\end{tabular}\end{center}$

Here, subtraction property of equality is used in the last step shown in the above.

As per the <em>Subtraction property </em>of equality, when some value is subtracted from both the sides of the equality, equality remains the same.
