Answer:
Step-by-step explanation:
A quadrilateral inscribed in a circle is called a <em>cyclic quadrilateral</em>. It has the special property that <em>opposite angles are supplementary</em>.
∠C = 180° - ∠A = 180° - 152°
∠C = 28°
__
∠Y = 180° -∠W = 180° -50°
∠Y = 130°
Answer:
Yes
Step-by-step explanation:
Initially it is provided that out of a total of 72 people 60 planned to vote for Jenny. This ratio as percentage shall be = = 83.33%
Later on the number of seniors polling in the survey increased to 80.
Now, out of 80 seniors, 56 planned to vote for Jenny.
In the percentage form this shall be
70%
Thus, there is a change of 83.33% - 70% = 13.33%
This shall be considered a significant drop as it is more than 10% in an audience size of less than 100.
1. Given that we have 4 green marbles, 4 pink marbles and 5 orange marbles, let us first find the probability that we select a pink marble.
We can find this by taking the number of pink marbles and dividing it by the total number of marbles:
Pr(P) = 4/(4 + 4 + 5)
= 4/13
2. Now that we have chosen one pink marble, we must find the probability that we choose an orange marble from the remaining marbles (4 green, 3 pink, 5 orange):
Pr(O) = 5/(4 + 3 + 5)
= 5/12
3. If we want to find the probability of picking a pink marble and then an orange marble, we must multiply the probabilities we have found in the first two steps:
Pr(P)*Pr(O) = (4/13)*(5/12)
= 20/156
= 5/39
Therefor, there is a probability of 5/39 that you pick a pink and then an orange marble.

Formula for an is 3n - 11
Step-by-step explanation:
- Step 1: Equation for a(n) = a + (n - 1)d where a = - 8, d = common difference = a2 - a1 = -5 - -8 = 3
⇒ a(n) = -8 + (n - 1)3 = - 8 + 3n - 3 = 3n - 11
