Answer:
Step-by-step explanation:
x^2 + 44^2 = 55^2
x^2 + 1936 = 3025
3025-1936 = 1089
sqrt(1089) = 33
x = 33
Answer:
b = 3 units
Step-by-step explanation:
Area of a parallelogram = base × height
Thus,
Area = 21 units²
base = b
height = 7
Plug in the value into the formula
Thus:
21 = b × 7
Divide both sides by 7
21/7 = b
3 = b
b = 3 units

Answer: 0.5507
Step-by-step explanation:
Given : The waiting time, in hours, between successive speeders spotted by a radar unit is a continuous random variable X with a cumulative distribution function

Since , the waiting time is in hours , then we can write 12 minutes as
hour i.e.0.2 hour.
Now, the probability of waiting fewer than 12 minutes between successive speeders is given by :-

Hence, the required probability = 0.5507
