Answer:
The correct way to set up the slope formula for the line that passes through points (5 , 0) and (6 , -6) is ⇒ C
Step-by-step explanation:
The formula of the slope of a line passes through points and
is
∵ The line passes through points (5 , 0) and (6 , -6)
∴ = 5 and
= 6
∴ = 0 and
= -6
Substitute these values in the formula of the slope
∵
∴
Let us look to the answer and find the same formula
The answer is:
The correct way to set up the slope formula for the line that passes through points (5 , 0) and (6 , -6) is
We do this by dividing 360°<span> by the number of sides, which is 8. (b) Calculate the size of each interior angle in the regular octagon. We do this by subtracting the size of each exterior angle, which is 45°, from </span>180°<span>. A regular polygon has equal exterior angles of 72°</span>
Answer:
b) The margin of error is approximately 3.24
e) The critical value is 1.7921.
Step-by-step explanation:
<u>Step(i</u>):-
Given sample size 'n' =20
Given sample standard deviation 's' = 10
<u><em> Margin of error </em></u>
<u><em>The margin of error is determined by</em></u>
<u><em /></u><u><em /></u>
<em>The level of significance ∝ =0.95</em>
<em>The degrees of freedom = n-1 = 20-1=19</em>
t₀.₉₅ = 1.729
Margin of error = 3.866
Step(ii):-
<u><em> Margin of error </em></u>
<u><em>The margin of error is determined by</em></u>
<u><em /></u><u><em /></u>
<u><em>Given another sample size n =30</em></u>
<em>The level of significance ∝ =0.95</em>
<em>The degrees of freedom = n-1 = 30-1=29</em>
t₀.₉₅ = 1.70
<u><em>Margin of error = 3.24</em></u>
