Answer:
2 5/8
Step-by-step explanation:
The expected value is the sum of each outcome times its probability.
X = 1 (3/16) + 2 (1/4) + 3 (3/8) + 4 (1/8) + 5 (1/16)
X = 3/16 + 1/2 + 9/8 + 1/2 + 5/16
X = 2 5/8
Answer:
11.00 pm
Step-by-step explanation:
Given that at 11:00 AM a bus left San Jose travelling to Los Angeles at 48 mph. Hence in 4 hours it would have travelled
48x4 = 192 miles
When the bus travelled 192 miles a motorcyclist started in the same direction with speed 72 mph
Difference in speed per hour = 72-48 = 24 mph
TO cover the distance of 72 miles, time taken for the motorcycist would be
192/24 = 8 hours
In 8 hours or at 11.00 p.m. motorcycle will catch upto the bus,
Using Pythagoras' theorem (a² + b² = c²), the correct answer is:
D. h² = a² - x²
Because a would be the hypotenuse, but h is not, so you have to rearrange the equation.
Answer:
-21 F
Step-by-step explanation:
it already was -14
then dropped 7
so it becomes
-14 - 7 = -12 f
