Answer:
Step-by-step explanation:
The area of the rectangle can be written as:
here, x is one side length, and h is the other side length. This area is said to be equal to 54 square meters.
The perimeter of a rectangle can be written as:
To express perimeter only in terms of x (in other words making it a function P(x)). we need to replace h. And this can be done by using the equation of area that we derived earlier.
now we can substitute this 'h' into our equation of the perimeter.
and voila! we have expressed P in terms of x only.
this can be written as P as a function of x as:
Answer:
The probability that the difference of the proportions (industrial - rural) is greater than 0.2 is 0.7054
Step-by-step explanation:
Solution
Given that:
n₁ = 1500
x₁ = 800
p₁ =800/1500 =0.533
q₁ = 1- 0.533 = 0.467
Thus,
n₂ =1000
x₂ = 300
p₂ = 300/1000 = 0.3
q₂ = 1-0.3 =0.7
So,
p₁ - p₂ = 0.533 - 0.3
=0.233
Now,
SE (p₁ - p₂ ) =√0.533 * 0467/150 + 0.3 * 0.7/1000
=0.0613
So,
p ( p₁ - p₂ > 0.2
= p ( Ƶ > 0.2 - 0.233/0.0613
p = ( Ƶ > - 0.54)
= 0.7054
Answer:
which statements is there meant to be a diagram? ?
The slope is 5/1 because b =5
Remember that the rule with multiplying exponents with the same base is to add the exponents together.
In this case: 
10^12 is your answer.
