Answer:
⇻<u>Option B. x - 2</u> is the correct answer.
Answer:
Step-by-step explanation:
We have to find out which two events are disjoint.
Two events are disjoint if both cannot happen simultaneously or Probability of both occurring is strictly 0.
a) Choose a student at random from a statistics class. Event A is that the student is a junior. Event B is that the student is a senior.
These are disjoint because a student cannot be a senior and junior both.
b) Choose a student at random from a statistics class. Event A is that the student is a psychology major. Event B is that the student is a statistics major.
Disjoint because same student cannot have psychology as well as statistics as major
c. Choose a student at random from a statistics class. Event A is that the student is at least 5'8" tall. Event B is that the student weighs at least 160 pounds.
These cannot be disjoint because there are chances for some students to be taller than 5 feet 8 inches and also having weight more than 160 lbs.
Answer:
x=3 in equation ;5x=15 and in equation C.
Answer:
The answer is B. After 20 seconds car A will be traveling at 65mph. This is because the speed is increasing 0.2 per second so 0.2 times 20 would equal 4. 61+4=65 Car B will be travelling at 65mph too because it is decreasing 0.5 per second and 0.5 times 20 would equal 10 and 75mph - 10mph would equal 65mph. The answer is A
