Answer:
why
Step-by-step explanation:
First find the slope, take derivative of both sides with respect to x.
2y dy/dx=3x^2+6x
solve for dy/dx
dy/dx=[3x^2+6x]/2y
plug in given vales of (1,2(
dy/dx=9/4
now you have everything you need to plug into point slope form
y-2=(9/4)(x-1)
answer is y=(9/4)x+(1/4)
Answer:
<h3><u>(20+15x)</u> is the right answer.</h3>
Answer:
We reject the null hypothesis.
Step-by-step explanation:
We are given the following information in the question:
Sample size, n = 71
Population variance is known.
Level of significance, α = 0.08
The null and alternate hypothesis are:
We use one-tailed z test to perform this hypothesis.
Formula:
Now,
Since,
We fail to accept the null hypothesis and reject it and accept the alternate hypothesis.
It's been a while since I have done these kind of questions, but I would say a 180 transformation would be my best answer. Hope this helps a bit!
