Answer:
7
Step-by-step explanation:
This is because any number combind with a variable will be considered a coefficient, for example in the equation 4x-13, 4 is the coefficient.
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:
Step-by-step explanation:
The surface area of a rectangular prism is
A=2(xy+xz+yz). where x,y,z are its dimensions, in this case
A=2(12(11)+12(10)+11(10))
A=2(132+120+110)
A=2(362)
A=724 cm^2
