True
If two polygons are similar, their corresponding angles are the same, while corresponding sides are all in the same ratio.
Answer: a. P (x<30) = 0.5276
b. P (30<x<35) = 0.0555
Step-by-step explanation: An <u>exponential</u> <u>distribution</u> is a distribution of time in which events happens at a constant average rate.
The rate is calculated as
with μ as the mean.
The probability density distribution for this type of distribution is
And probability is calculated as
For tuning of an engine, the rate is
λ = 0.025
a. Probability of less than 30 minutes:
P (X < 30) = 0.5276
<u>Probability of tuning in 30 minutes or less is </u><u>52.76%</u><u>.</u>
<u />
b. Probability of between 30 and 35 can be described as
P (X < 35) = 0.5831
P (X < 30) = 0.5276
Then:
P (30 < X < 35) = 0.0555
<u>Probability of tuning an engine between 30 and 35 minutes is </u><u>5.55%.</u>

5.50 divided by 10 gives you 55. There will be 55 dimes in $5.50 :)
6(x + 4) = 2(y + 5)..........Multiply everything out
6x + 24 = 2y + 10..........Solve for 2y by subtracting 10 from both sides
6x + 24 - 10 = 2y + 10 - 10
6x + 14 = 2y..................Solve for y by dividing both sides by 2
2y/2 = (6x + 14)/2
y = 3x + 7......................ANSWER.
