F^-1(x) is the inverse so...
f^-1(x) = (-1/5)x - 11/5

Answer:
y = 2x + -5
Step-by-step explanation:
If you look at the graph, you can find that the slope is 2/1 which is simply just a slope of 2. The y-intercept can be found x = 0, so plug in 0 for x, solve from there and you get -5 for the y-intercept.
Answer:
b) μ = 2 and σ = 1.29
Step-by-step explanation:
<u><em>Step(i):-</em></u>
<em>Given that the A spinner is divided into six equal-sized sectors labelled 1 through 6</em>
<em>Given that the probability of labelled '1'</em>
<em> </em>
=0.16
<em> q = 1-p = 1- 0.16 = 0.84</em>
Let 'X' be a random variable in binomial distribution
The mean of the binomial distribution
μ = n p
μ =
<em>The mean of the binomial distribution = 2</em>
<u><em>Step(ii):-</em></u>
The standard deviation of X
σ ![= \sqrt{npq}](https://tex.z-dn.net/?f=%3D%20%5Csqrt%7Bnpq%7D)
σ = ![\sqrt{12(0.16)(0.84}](https://tex.z-dn.net/?f=%5Csqrt%7B12%280.16%29%280.84%7D)
σ = ![1.269](https://tex.z-dn.net/?f=1.269)
<em>The standard deviation of the binomial distribution</em>
<em> </em> σ = ![1.269](https://tex.z-dn.net/?f=1.269)
