<h3>
Answer:</h3>
Graph (0, 25) and (50, 0)
<h3>
Step-by-step explanation:</h3>
Intercept form of an equation for a line is ...
- x/(x-intercept) + y/(y-intercept) = 1
Dividing each equation by the constant on the right can put it into this form.
<em>First equation</em>:
<em>Second equation</em>:
This tells you the second equation can be graphed using the points ...
... (50, 0) and (0, 25) . . . . . matches the second selection
Answer:
q=90 units.
Step-by-step explanation:
Answer:
Step-by-step explanation:
Data given and notation
represent the sampe size for A
represent the sample size for B
represent the sample deviation for A
represent the sample deviation for B
represent the significance level provided
F test is a statistical test that uses a F Statistic to compare two population variances, with the sample deviations s1 and s2. The F statistic is always positive number since the variance it's always higher than 0. The statistic is given by:
Solution to the problem
System of hypothesis
We want to test if we have the same variation, so the system of hypothesis are:
H0: 
H1: 
Calculate the statistic
Now we can calculate the statistic like this:
Answer:
f x + 2f + 4.
Step-by-step explanation:
