Answer:
The correct answer is (D)
Step-by-step explanation:
Given the events X and Y:
X = the price of stock X has increased
Y = the price of stock Y has increased
That means that the complement of these events are:
X' = the price of stock X has not increased
Y' = the price of stock Y has not increased
Hence, the event "the price of stock X has increased and the price of stock Y has not increased" may be written as:
X ∩ Y′
Answer:

Answer:
x = 16
Step-by-step explanation:
(5x + 12)° + (6x - 8)° = 180°
(5x + 12 + 6x - 8)° = 180°
(11x + 4)° = 180°
11x + 4 = 180
11x = 180- 4
11x = 176
x = 176/11
x = 16
P-5=3s-15 because Pete is 20 and Sam is 10. 20-5= 15 and 3(10)-15 also equals 15. The answer is C.
Answer:
Step-by-step explanation:
Given that a survey was conducted that asked 1004 people how many books they had read in the past year.
Results are:
x bar =12.5
s = 16.6
n = 1004
Std error of sample = 
Since population std dev is not known t critical value can be used for confidence interval.
df = 1004-1 =1003
t critical = 1.96
Margin of error 
Confidence interval lower bound 
Upper bound
