This equation uses y and x so it cannot be factorised.
Let’s try the equation y^2 - 12y + 36 = 0
Look for two factors of 36 that add to -12.
This would be -6 and -6
(y - 6)(y - 6) = 0
(y - 6) must equal 0
y = 6
Answer:
angle BNU = 60 degrees
Step-by-step explanation:
3x + 8 = 44
3x = 36
x = 12
5x = 60
The depreciated value is given by
.. v(t) = $25,000*0.92^t . . . . . t in years
Then
.. v(7) = $25,000*0.92^7 ≈ $13,946
Complete Question
Determine whether the normal sampling distribution can be used. The claim is p < 0.015 and the sample size is n=150
Answer:
Normal sampling distribution can not be used
Step-by-step explanation:
From the question we are told that
The null hypothesis is ![H_o : p = 0.015](https://tex.z-dn.net/?f=H_o%20%20%3A%20%20p%20%3D%20%200.015)
The alternative hypothesis is ![H_a : p < 0.015](https://tex.z-dn.net/?f=H_a%20%20%3A%20%20p%20%20%3C%20%200.015)
The sample size is n= 150
Generally in order to use normal sampling distribution
The value ![np \ge 5](https://tex.z-dn.net/?f=np%20%20%5Cge%20%205)
So
![np = 0.015 * 150](https://tex.z-dn.net/?f=np%20%3D%20%200.015%20%2A%20150)
![np = 2.25](https://tex.z-dn.net/?f=np%20%3D%20%202.25)
Given that
normal sampling distribution can not be used
