Answer:
A t-score of 1.701 should be used to find the 95% confidence interval for the population mean
Step-by-step explanation:
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 29 - 1 = 28
Now, we have to find a value of T, which is found looking at the t table, with 28 degrees of freedom(y-axis) and a confidence level of 0.95(
). So we have T = 1.701.
A t-score of 1.701 should be used to find the 95% confidence interval for the population mean
Sample Response: The graphs are reflections of each other over the y-axis. The graph of g(x) shoes exponential decay, while the graph of f(x) shows exponential growth.
I’m pretty sure it’s 10 and 16
Answer:
The answer to your question is Perimeter = [4x³ + 14x² + 50x - 150] / x(5 + x)
Step-by-step explanation:
Data
Width = (x² + 2x - 15)/x
Length = (3x² + 4x)/ (5 + x)
Process
1.- Write the formula for the perimeter of a rectangle
Perimeter = 2W + 2L
2.- Substitution
Perimeter = 2(x² + 2x - 15)/x + 2(3x² + 4x)/(5 + x)
3.- Simplification
Perimeter = (2x² + 4x - 30)/x + (6x² + 8x)/(5 + x)
4.- Sum the fractions
Least common factor = x(5 + x)
Perimeter = [(2x² + 4x - 30)(5 + x) + (x(6x² + 8x)] / x(5 + x)
-Simplification
Perimeter = [10x² + 20x - 150 - 2x³ - 4x² + 30x + 6x³ + 8x²] / x(5 + x)
Perimeter = [4x³ + 14x² + 50x - 150] / x(5 + x)
The ratio of the areas is the one-to-one measure squared. In order to find the ratio of their volumes, which is a cubed measure, we have to find the one-to-one and them cube it. The square root of 1/16 is 1/4. Now if we cube 1/4 to get the volume, it will be 1/64.
