Complete the steps in order to write the inverse of f(x) = x + 5

rusak2 [61]

Answer:

see the procedure

Step-by-step explanation:

we have

$f(x)=x+5$

step 1

Let

y=f(x)

$y=x+5$

step 2

Exchange the variables

x for y and y for x

$x=y+5$

step 3

Isolate the variable y

$y=x-5$

step 4

Let

$f^{-1}(x)=y$

$f^{-1}(x)=x-5$

It is possible to score higher than 1600 on the combined mathematics and reading portions of the SAT, but scores 1600 and above

Citrus2011 [14]

Answer:

The proportion of scores reported as 1600 is 0.0032

Step-by-step explanation:

Let X be the score for 1 random person in SAT combining maths and reading. X has distribution approximately N(μ = 1011,σ = 216).

In order to make computations, we standarize X to obtain a random variable W with distribution approximately N(0,1)

$W = \frac{X-\mu}{\sigma} = \frac{X-1011}{216} \simeq N(0,1)$

The values of the cummulative distribution function of the standard Normal random variable, lets denote it $\phi$ are tabulated, you can find those values in the attached file. Now, we are ready to compute the probability of X being bigger than 1600

$P(1600< X) = P(\frac{1600-1011}{216} < \frac{X-1011}{216}) = P(2.7269 < W) = 1- \phi(2.7269)\\= 1- 0.9968 = 0.0032$

Hence, the proportion of scores reported as 1600 is 0.0032.
