There is a 40% possibility of making 0 points.

There is a (.6)(.4) = 24% possibility of making 1 point.

There is a (.6)(.6) = 36% possibility of making 2 points.

Expected value = 0 * .40 + 1 * .24 + 2 * .36 = 0.96

a) She is most likely to make 0.96 points.

Expected value = 0 * ( .4) + 1 * (.6)(.3) + 2 * (.6)(.7)

she is most likely to make 1.8 points.

Hope I helped.

Could you please mark me brainliest.

Answer:

OPTION C: Sin C - Cos C = s - r

Step-by-step explanation:

ABC is a right angled triangle. ∠A = 90°, from the figure.

Therefore, BC = hypotenuse, say h

Now, we find the length of AB and AC.

We know that: $\textbf{Sin A} = \frac{\textbf{opp}}{\textbf{hyp}}$

and $\textbf{Cos A} = \frac{\textbf{adj}}{\textbf{hyp}}$

Given, Sin B = r and Cos B = s

⇒ $Sin B = r = \frac{opp}{hyp} = \frac{AC}{BC} = \frac{AC}{h}$

⇒ $\textbf{AC} = \textbf{rh}$

Hence, the length of the side AC = rh

Now, to compute the length of AB, we use Cos B.

$Cos B = s = \frac{adj}{hyp} = \frac{AB}{BC} = \frac{AB}{h}$

⇒ $\textbf{AB} = \textbf{sh}$

Hence, the length of the side AB = sh

Now, we are asked to compute Sin C - Cos C.

$Sin C = \frac{opp}{hyp}$

⇒ $Sin C = \frac{AB}{BC}$

$= \frac{sh}{h}$

= s

Sin C = s

$Cos C = \frac{adj}{hyp}$

$\implies Cos C = \frac{AC}{BC}$

⇒ Cos C = $\frac{rh}{h}$

Therefore, Cos C = r

So, Sin C - Cos C = s - r, which is OPTION C and is the right answer.

Answer:

See attached graph

Step-by-step explanation:

The equation is y-3=(x + 6)

Write the equation in a slope intercept form, then graph the equation on a graph tool to see the points that line on the line.

Alternatively , using the coordinates in the answer choices given, input them in the equation of the graph and select the answer choice that has all its coordinates true to the equation.

y-3 = x+6 -----can be written as : y= x+9

Graph y= x+9 to see the graph and the points that are on the line as attached.

Answer: Tables, graphes, and equation are realted because they all have the same information but just in diffrent ways. the advantage of a table is that you can see more information and what other possblities and fill in missing spots. graphes you can fid the equation on it by counting on it. The advantage of a equation is that you can solve it and get the answer the fastets
