Answer:
h0 : u = 15 amps
h1 : u ¥ 15 amps
Note: h0 is the null hypothesis
h1 is the alternative hypothesis
u is the mean
¥ is used to represent 'not equal to'
It would be the first one because it says that there are 4 times as many red roses as pink roses and so that would be represented r=4p
Hope this helps! Good luck!
X = 25, y = 14.
This is possible to solve because the vertical angles (7y and 5y + 28 ; 3x +7 and 4x - 18) are equal to each other. To solve for x, just set the two x equations equal to each other. The same is done for y with the y equations.
Step-by-step explanation:
log <base a> b = x
means
a^x = b
So
3^2 = x^2+7x+21
x^2 + 7x + 21 - 9 = 0
x^2 + 7x + 12 = 0
(x+3)(x+4)
x = -3 or -4
Given:

To find:
The f'(y).
Solution:
Chain rule of differentiation:
![[f(g(x))]'=f'(g(x))g'(x)](https://tex.z-dn.net/?f=%5Bf%28g%28x%29%29%5D%27%3Df%27%28g%28x%29%29g%27%28x%29)
Differentiation of exponential:

We have,

Differentiate with respect to y.



Therefore, the differentiation of the given function is
.
