The distributive property of multiplication is a very useful property that lets you rewrite expressions in which you are multiplying a number by a sum or difference.
Answer:
(c)
(b) The probability that time taken by Ayesha to prepare breakfast exceeds 33 minutes is 0.20.
(c) The probability that cooking or preparation time is within 2 mins of the mean time is 0.40.
Step-by-step explanation:
The random variable <em>X</em> follows a Uniform (25, 35).
(a)
The probability density function of an Uniform distribution is:
Then the probability density function of the random variable <em>X</em> is:
(b)
Compute the value of P (X > 33) as follows:
Thus, the probability that time taken by Ayesha to prepare breakfast exceeds 33 minutes is 0.20.
(c)
Compute the mean of <em>X</em> as follows:
Compute the probability that cooking or preparation time is within 2 mins of the mean time as follows:
Thus, the probability that cooking or preparation time is within 2 mins of the mean time is 0.40.
Answer:
x = 5±sqrt(3)
Step-by-step explanation:
(x-5)^2=3
Take the square root of each side
sqrt((x-5)^2)=±sqrt(3)
x-5 = ±sqrt(3)
Add 5 to each side
x-5 +5= 5±sqrt(3)
x = 5±sqrt(3)
