Set side lengths equal to each other and solve for x. All sides are equal lengths in a square.
6x - 1 = 4x + 6
2x = 7
X = 3.5
Plug in x in one of the equations
4 x 3.5 + 6 = 20
Each side is 20 cm

Answer:
(a) 
(b) 
(c) Fail to reject 
Step-by-step explanation:
Given




Solving (a): The test statistic
This is calculated as:

So, we have:



--- approximated
Solving (b): Range of p value
First, calculate the degree of freedom (df)



Using:
--- significance level
The p value at:
is:

and the range is:


Solving (c): The conclusion
Compare the p value to the level of significance value
We have:


By comparison:

because:

<em>Hence, the conclusion is: fail to reject </em>
<em></em>
Answer:
2
Step-by-step explanation:
13 x 17=221
19 x 23=437
437+221=658
658 divided by 2= 329
2 is prime and the least
