Answer:
y=5x+9
Step-by-step explanation:
Firstly, we have to use the equation y=mx+b, where m is the slope and b is the y intercept.
We know that m=5, x=0 and y=9.
So why not plug them into the equation to find b?
9=5(0)+b
9=0+b
9=b
Therefore, y=5x+9 is your final answer.

Answer:
f(x) = -1/2·10^x
Step-by-step explanation:
The y-intercept is -1/2.
The common ratio is (-1/20)/(-1/200) = 10, so the exponential function can be written as ...
f(x) = -1/2·10^x
Answer:
Degree of freedom = 19
Step-by-step explanation:
We are given the following information in the question:
Sample size, n = 20
For a t-test hypothesis it was claimed that the population mean is greater than 89 second.
1) df
Df denotes the degree of freedom.
- The Degrees of Freedom refers to the number of values involved in the calculations that have the freedom to vary.
2) Degree of freedom = n - 1
where n is the sample size
Degree of freedom = 20 - 1 = 19
