Answer:
I would say 5 kg because you get more kg with a little bit more money added
Answer: I think it should be a: 1/4 inch
Step-by-step explanation:
Answer:
(7, 0).
Step-by-step explanation:
We have y = 3(x - 7)
y = 3x - 21
Point-slope form is
y - y1 = 3(x - x1)
y - y1 = 3x - 3x1
Comparing this to the equation y = 4x - 21 we see that y1 = 0 and x1 = 7.
Answer:
Step-by-step explanation:
Given that:
A simple random sample n = 28
sample standard deviation S = 12.65
standard deviation
= 11.53
Level of significance ∝ = 0.05
The objective is to test the claim that the number of pieces in a set has a standard deviation different from 11.53.
The null hypothesis and the alternative hypothesis can be computed as follows:
Null hypothesis:

Alternative hypothesis:

The test statistics can be determined by using the following formula in order to test if the claim is statistically significant or not.







From the chi-square probabilities table at 0.975 and degree of freedom 27;
= 14.573


From the chi-square probabilities table at 0.975 and degree of freedom 27;
43.195
Decision Rule: To reject the null hypothesis if
; otherwise , do not reject the null hypothesis:
The rejection region is 
Conclusion:
We fail to reject the null hypothesis since test statistic value 32.5002125 lies between 14.573 and 43.195.
No solution
========
The lines are parallel
eg
y = 2x + 3; y = 2x + 5
Infinite solutions
============
When one equation reduces to the second one.
2y = 10x + 6
y = 5x + 3 When you divide the first one by 2, you get the second one.
