Answer:
A reasonable estimate for the solution is the point (1.1,-1.9)
Step-by-step explanation:
we have
-----> equation A
----> equation B
Solve the system by graphing
Remember that the solution of the system of equations is the interection point both graphs
using a graphing tool
The solution is the point (1.091,-1.818)
see the attached figure
therefore
A reasonable estimate for the solution is the point (1.1,-1.9)
Since we want to find the value of <em>k</em><em> </em>where the limit exists, set both equations equal to each other. Then substitute <em>x</em> = -1 in for each equation to find <em>k</em><em>.</em>
<em></em>
1. Set both equations equal.
2. Substitute <em>x</em><em> </em>= -1.
3. Solve for <em>k</em><em> </em>by adding <em>k</em><em> </em>to both sides. Continue the process of solving the equation.
Thus, <em>k</em><em> </em>= -2. Check by graphing the function.
Answer:
Step-by-step explanation:
Given that :
the null and the alternative hypothesis are computed as :
This is a two tailed test
This is because of the ≠ sign in the alternative hypothesis which signifies that the rejection region in the alternative hypothesis are at the both sides of the hypothesized mean difference .
Decision Rule: at the level of significance ∝ = 0 . 10
The decision rule is to reject the null hypothesis if z < - 1 . 64 and z > 1 . 64
