Answer:
The probability that a randomly chosen tree is greater than 140 inches is 0.0228.
Step-by-step explanation:
Given : Cherry trees in a certain orchard have heights that are normally distributed with inches and inches.
To find : What is the probability that a randomly chosen tree is greater than 140 inches?
Solution :
Mean - inches
Standard deviation - inches
The z-score formula is given by,
Now,
The Z-score value we get is from the Z-table,
Therefore, the probability that a randomly chosen tree is greater than 140 inches is 0.0228.
(3x10^8) x 8 = 2400000000
OR 2.4x10^9
Step-by-step explanation:
step 1. Where is the original equation? let's assume it is y = x^2
step 2. to shift to the right 3 places replace x with x - 3 and to shift 4 down subtract 4 from the equation
step 3. y = (x - 3)^2 - 4.
Ryan: y=10x+25 Alex: y=11x+20
a) Mr. Smith should choose Alex because the price would be $42 compared to Ryan which would be $45
b) Mr.Smith could choose either Ryan or Alex because they would both charge $75
