Answer:
<h2>100°</h2>
Step-by-step explanation:
The inscribed angle R is half of the central angle O that subtends the same arc on the circle.
Therefore m∠O = 2m∠R
m∠O = 2(50°) = 100°
Only 8 is not a function. it is not because there are 2 lines coming from the first domain elemenr
Answer with explanation:
Given : A clinical trial tests a method designed to increase the probability of conceiving a girl.
Also, in a normal case the probability of conceiving a girl is 0.5.
Let p be the proportion of girls born.
Then , we have
Sample size : n= 345
The sample proportion of girls born =
Critical value : 
The confidence interval for population proportion is given by :_
Since the confidence interval do not contains 50% that means there is increase in the probability of conceiving a girl, then it can be concluded that we have statistical evidence that the the clinical trial method increase the probability of conceiving a girl.
Answer:
Number of doubles games = 6
Number of singles games = 7
Step-by-step explanation:
Let the number doubles be d and number of singles be s.
There are 13 matches in progress.
d + s = 13 ----------------------eqn 1
There are 38 people playing tennis. A doubles match requires 4 players, and a singles match requires 2 players.
4 d + 2 s = 38 ----------------------eqn 2
eqn 1 x 2
2d + 2s = 26 ----------------------eqn 3
eqn 2 - eqn 3
4 d + 2 s - 2d + 2s = 38 - 26
2d = 12
d = 6
Substituting in eqn 1
6 + s = 13
s = 7
Number of doubles games = 6
Number of singles games = 7
