Solution:
- Perimeter of Rectangle = 346
Let Required length of breadth be x
- Then, Length of Rectangle = 45 + x
Now, We have ;
- Perimeter of Rectangle = 2(l+b)
- Perimeter of Rectangle = 2 ( 45 + x + x
- 346 = 2 ( 45 + 2x )
- 346 = 90 + 4x
- 346 - 90 = 4x
- 256 = 4x
- x = 256 ÷ 4
- x = 64 inches
So, Length of Rectangle = x + 46
Length of Rectangle = 64 + 46
Length of Rectangle = 110 inches
Now, Breadth of Rectangle = 64 inches.
(x^4 - 9)(x^3 + 9)
This is a binomial * binomial. Use the FOIL method for multiplying.
First, outer, inner, last.
x^4 * x^3 = x^7
x°^4 * 9 = 9x^4
-9 * x^3 = -9 x^3
-9 * 9 = -81
Putting it back together.
x^7 +9x^4 -9x^3 - 81
Answer:
The upper bound of the confidence interval is 0.34
Step-by-step explanation:
Here in this question, we want to calculate the upper bound of the confidence interval.
We start by calculating the margin of error.
Mathematically, the margin of error = 0.29 -0.24 = 0.05
So to get the upper bound of the confidence interval, we simply add this margin of error to the mean
That would be 0.05 + 0.29 = 0.34
