H + 20 = 35 - 4h
-35 -35
h - 15 = -4h
-h -1h
-15 = -5h
-15/-5h
h= 3
Answer:
![H_0 : \mu_1 - \mu_2 = 0](https://tex.z-dn.net/?f=H_0%20%3A%20%5Cmu_1%20-%20%5Cmu_2%20%3D%200)
![H_a : \mu_1 - \mu_2 \ne 0](https://tex.z-dn.net/?f=H_a%20%3A%20%5Cmu_1%20-%20%5Cmu_2%20%5Cne%200)
Step-by-step explanation:
Let the salted package be represented with 1 and the unsalted, 2.
So:
Mean of salted package
Mean of unsalted package
Considering the given options, the null hypothesis is that which contains =.
So, the null hypothesis is:
![H_0 : \mu_1 - \mu_2 = 0](https://tex.z-dn.net/?f=H_0%20%3A%20%5Cmu_1%20-%20%5Cmu_2%20%3D%200)
The opposite of = is
. So, the alternate hypothesis, is that which contains ![\ne](https://tex.z-dn.net/?f=%5Cne)
So, the alternate hypothesis is:
![H_a : \mu_1 - \mu_2 \ne 0](https://tex.z-dn.net/?f=H_a%20%3A%20%5Cmu_1%20-%20%5Cmu_2%20%5Cne%200)

Answer:
Slope = 9/6
Step-by-step explanation:
Step 1: We have formula to find the slope if we are given two point.
<h3>slope =
![\frac{(y2 - y1)}{(x2 - x1)}](https://tex.z-dn.net/?f=%5Cfrac%7B%28y2%20-%20y1%29%7D%7B%28x2%20-%20x1%29%7D)
</h3>
Given points (-1, -5) and (5, 4)
Here x1 = -1, y1 = -5 and x2=5 and y2 = 4
Step 2: Plug in those values into formula and simplify.
Slope = (4 - (-5)) / (5 - (-1))
= (4 + 5)/(5 + 1) -(-5)= 5 and -(-1) = 1
Slope (m) = 9/6
Thank you.
Hope you will understand this.
Evaluate
![\dfrac{f(5)+g(1)}{f(6)-g(-2)}](https://tex.z-dn.net/?f=%5Cdfrac%7Bf%285%29%2Bg%281%29%7D%7Bf%286%29-g%28-2%29%7D)
where
![f(x)=x-4](https://tex.z-dn.net/?f=f%28x%29%3Dx-4)
and
![g(x)=3x+6](https://tex.z-dn.net/?f=g%28x%29%3D3x%2B6)
f(5) = 5 - 4 = 1
g(1) = 3 * 1 + 6 = 3 + 6 = 9
f(6) = 6 - 4 = 2
g(-2) = 3 * (-2) + 6 = -6 + 6 = 0
So,
![\dfrac{f(5)+g(1)}{f(6)-g(-2)}\\\\\\ =\dfrac{1+9}{2-0}\\\\\\ =\dfrac{10}{2}](https://tex.z-dn.net/?f=%5Cdfrac%7Bf%285%29%2Bg%281%29%7D%7Bf%286%29-g%28-2%29%7D%5C%5C%5C%5C%5C%5C%20%3D%5Cdfrac%7B1%2B9%7D%7B2-0%7D%5C%5C%5C%5C%5C%5C%20%3D%5Cdfrac%7B10%7D%7B2%7D)
