Answer:
the total price is 64.89
Step-by-step explanation:
63 / 100 =
0.63 * 103 = 64.89
Expected value is $20.20
Step-by-step explanation:
Here, we want to calculate the expected value
What we have to do here is to multiply the probability by the payout value; after which we add all values
Thus, we have the payout value as;
1(0.12) + 4(0.2) +6(0.38) + 8(0.2) + 10(0.1)
= 0.12 + 0.8 + 2.28 + 1.6 + 1
First, we are given that the inscribed angle of arc CB which is angle D is equal to 65°. This is half of the measure of the arc which is equal to the measure of the central angle, ∠O.
m∠O = 2 (65°) = 130°
Also, the measure of the angles where the tangent lines and the radii meet are equal to 90°. The sum of the measures of the angle of a quadrilateral ACOB is equal to 360°.
m∠O + m∠C + m∠B + m∠A = 360°
Substituting the known values,
130° + 90° + 90° + m∠A = 360°
The value of m∠A is equal to 50°.
<em>Answer: 50°</em>
I think it's B but I'm not 100% sure
Let's try this.
First, we have the absolute value of -4(-2)-8, or the absolute value of 8-8, so 0.
Let's forget about that, now. It's 0, it adds no value. Let's not worry about it.
For the next, we see the absolute value of -1-(-2)^2
Or:
-1-4, or -5.
Next is 2(-2)^2, or 2(4) = 8.
Therefore, we have -5+8 =3.

Otherwise, I hope this helps!
