Answer:

Area is measured in square units because The area of a figure is the number of squares required to cover it completely, like tiles on a floor. Area of a square = side times side. Since each side of a square is the same, it can simply be the length of one side squared.

Answer:

f(x)+g(x)=4x^3+x−7

Step-by-step explanation:

To find f(x) + g(x) add the expressions together by combining like terms. Recall like terms are terms with the same base and exponent.

f(x) + g(x) = x - 7 + 4x^3

f(x) + g(x) = 4x^3 + x -7

Population mean = 80

alexira [117]

Answer:

The answer is : 0.0597

Step-by-step explanation:

Population mean = μ = 80

Standard deviation = σ = 20

Sample = N = 60

σ_mean = σ/√N

= (20)/√(60) = 2.582

Now we will find z1 and z2.

z1 = {(84) - μ}/σ_mean = ${(84)-(80)}/(2.582)= 1.549$

z2 = {(88) - μ}/σ_mean = ${(88)-(80)}/(2.582)= 3.098$

Now probability that the sample mean will be between 84 and 88 is given by:

Prob{ (1.549) ≤ Z≤ (3.098) } = (0.9990) -(0.9393) = 0.0597
