Hello :

5a-5 +2a =2a
5a =5
a=1 ( refused)
conclusion : <span>none</span>
Answer:
since p value < x(0.05) so we reject the null hypothesis
step 5 ( conclusion)
reject the null hypothesis and there is sufficient evidence to support the claim that the true average percentage differs from 5.5.
Step-by-step explanation:

To find the value of q, we need to find d(-8). Put another way, we need to find the value of d(x) when x = -8





So this means q = 0. Note that -0 is just 0.
===========================================
The value of r will be a similar, but now we use f(x) this time.
Plug in x = 0





Therefore, r = 2.
===========================================
For s, we plug x = 10 into f(x)





So s = 3.
===========================================
Finally, plug x = 10 into d(x) to find the value of t





A shortcut you could have taken is to note how d(x) = -f(x), so this means
d(10) = -f(10) = -9 since f(10) = 9 was found in the previous section above.
Whichever method you use, you should find that t = -3.
===========================================
<h3>In summary:</h3><h3>q = 0</h3><h3>r = 2</h3><h3>s = 3</h3><h3>t = -3</h3>
Answer:
slope = - 2
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 3, 6) and (x₂, y₂ ) = (3, - 6) ← 2 points on the line
m =
=
= - 2
