According to the American music industry, the length of a song is normally distributed with a mean of 240 seconds and standard deviation thirty seconds. Suppose a random sample of fifteen songs is selected from the morning program. what is the probability that the length of the song is between 225 and 260 seconds long?
Answer:
96.89%
Step-by-step explanation:
Find the standard error:
s = σ/√n
s = 30 / √15
s = 7.75
Find the z-scores:
z = (x − μ) / s
z₁ = (225 − 240) / 7.75
z₁ = -1.94
z₂ = (260 − 240) / 7.75
z₂ = 2.58
Find the probability.
P(-1.94 < Z < 2.58) = P(Z<2.58) − P(Z<-1.94)
P(-1.94 < Z < 2.58) = 0.9951 − 0.0262
P(-1.94 < Z < 2.58) = 0.9689
Given h(x) = -3x – 5, solve for x when h(x) = –2.
The value of x will be equal to -1 when the value of h(x) is -2.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that h(x) = -3x – 5, and the value h(x) = -2. The value of x will be calculated as below:-
h(x) = -3x – 5,
-2=-3x -5
3=-3x
x=-1
Therefore, the value of x will be equal to -1 when the value of h(x) is -2.

The area of a square is given by A=s2, where s is the length of each side of the square. If the area of a square room is 81 square meters, what is the length of one side of the room in meters?
Answer: The length of one side is 9m.
Step-by-step explanation:
If area is 81 square meters, that means A = 81 m^2.
Since A = s^2, we can substitute s^2 for A. Then
(s^2) = 81 m^2
Take the square root of both sides to solve for s:
(s^2)^(1/2) = (81 m^2)^(1/2)
s = 9 m
