Answer:
The answer is 30
Step-by-step explanation:
You have to do 5 times 2. 5 times 2 is 10. Then you have to do 10 times 3. 10 times 3 is 30. So you will get 30 as your answer.

Answer:
23 m and 15 m
Step-by-step explanation:
THE BASE OF A RECTANGLE IS 8 M GREATER THAN THE HEIGHT, THE AREA MEASURES 65 SQUARE METERS HOW MUCH DO THE BASE AND HEIGHT MEASURE?
Let the height of the rectangle is h.
Base = 8+h
Area of the rectangle, A = 65 m²
We need to find the base and height of the rectangle. The area of a rectangle is given by :
A = bh
So,
Neglecting negative value, h = 15 m
Base = 8+15 = 23 m
So, the base and height of the rectangle is 23 m and 15 m respectively.
Answer:
a) 0.8132 or 81.32%
b) 0.1868 or 18.68%
c) 0.6116 or 61.16%
d) 0.7667 minutes
e) 0.8667 minutes
f) 0.1 minutes
Step-by-step explanation:
a)
If f(x) = 0.85-0.35x (0<x<2) is the <em>PDF</em> and X is the random variable that measures the time it takes for a trainee to complete the task, the probability a trainee will complete the task in less than 1.31 minutes is P(X<1.31)
b)
The probability that a trainee will complete the task in more than 1.31 minutes is
P(X>1.31) = 1 - P(X<1.31) = 1 - 0.8132 = 0.1868
c)
The probability it will take a trainee between 0.25 minutes and 1.31 minutes to complete the task is P(0.25<X<1.31)
d)
the expected time it will take a trainee to complete the task
is<em> E(X)
</em>
e)
f)
