Answer:
![E(x)=1](https://tex.z-dn.net/?f=E%28x%29%3D1)
Step-by-step explanation:
From the question we are told that:
Sample mean 1 ![\=x_1=$9](https://tex.z-dn.net/?f=%5C%3Dx_1%3D%249)
Sample mean 1 ![\=x_2=$8](https://tex.z-dn.net/?f=%5C%3Dx_2%3D%248)
Sample standard deviation 1 ![\sigma_1 = $2](https://tex.z-dn.net/?f=%5Csigma_1%20%3D%20%242)
Sample standard deviation 1 ![\sigma_2 = $1](https://tex.z-dn.net/?f=%5Csigma_2%20%3D%20%241)
Generally the equation for Point estimate is mathematically given by
![E(x)=\=x_1-\=x_2](https://tex.z-dn.net/?f=E%28x%29%3D%5C%3Dx_1-%5C%3Dx_2)
![E(x)=9-8](https://tex.z-dn.net/?f=E%28x%29%3D9-8)
![E(x)=1](https://tex.z-dn.net/?f=E%28x%29%3D1)
I disagree. The first one is false. No exponent rules apply if the bases AND the exponents are different.
The second one is true. Bases are the sane so you add exponents. You get 3 to the -5 power. Written with positive exponents it’s 1/3 to the 5.
Figure it out tonta tonta
Answer:
Suppose f and g are two functions such that
1. (g ◦ f)(x) = x for all x in the domain of f and
2. (f ◦ g)(x) = x for all x in the domain of g
then f and g are said to be inverses of each other. The functions f and g are said to be
invertible.
. Properties of Inverse Functions: Suppose f and g are inverse functions.
• The rangea of f is the domain of g and the domain of f is the range of g
• f(a) = b if and only if g(b) = a
• (a, b) is on the graph of f if and only if (b, a) is on the graph of g
Step-by-step explanation:
55 Times 74 Equals 4,070. 4070 Plus 59 Equals 4129. 4129 + 88 = 4217 + x = 4127x. Hope this helps!
