So you want to make it: total distance (d) = rate (r) × total time (t), solving for r: r = d / t
r = (420mi) / (3h+214h), r = 420mi / 217h
r = 1.935mi/h = 1.94mi/h
Answer:
1. Pythagorean Theorem
2. SSS
3. C
4. the definition of right triangle
Answer: 40%
Step By Step: Set this in a proportion. Since 12 out of 30 finished, it would be 12/30. Since you are dealing with percent, it would be x/100 because percent means per hundred. Set these equal to each other. 12/30 = x/100. Cross multiply. 30x = 1200. Divide. X = 40.
can't simultaneously be equal to 1 and larger than 2, so the probability must be zero.
Did you mean to find the probability of the union? In that case, since the events are mutually exclusive, you would be able to write
where
is the probability density function and
is the cumulative distribution function for the random variable
.
