In Exercise, sketch the graph of the function.<br> f(x) = 0.5 ln x

BartSMP [9]

Answer:

To $f(x)=0.5ln(x)}$

view graph

Step-by-step explanation:

To $f(x)=0.5ln(x)}$ we can say that $f(x)=y=0.5ln(x)}$ then we find cut points. For y=0 $0=0.5ln(x)$ ⇒ $0=lnx\\e^{0}=e^{lnx}\\1=x$

as can be seen in the graph for any value of y greater that 0, x will always take values greater than 1, for values of y less than 0, x will take values less than 1

If f(x) and its inverse function, f Superscript negative 1 Baseline (x), are both plotted on the same coordinate plane, where is

bearhunter [10]

Answer:

(2,2)

Step-by-step explanation:

step 1

Find the equation of f(x)

is a line that passes through the points (0,6) and (3,0)

Find the slope

$m=(0-6)/(3-0)=-2$

The function f(x) in slope intercept form is equal to

$f(x)=-2x+6$

step 2

Find the inverse

Let y=f(x)

$y=-2x+6$

Exchange the variables x for y and y for x

$x=-2y+6$

Isolate the variable y

$2y=-x+6$

$y=-0.5x+3$

Let

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

$f^{-1}(x)=-0.5x+3$

step 3

Solve the system of equations

$f(x)=-2x+6$

$f^{-1}(x)=-0.5x+3$

equate both functions

$-0.5x+3=-2x+6$

solve for x

$2x-0.5x=6-3$

$1.5x=3$

$x=2$

substitute the value of x in any of the functions

$f(x)=-2(2)+6=2$

The solution is the point (2,2)

therefore

Their point of intersection is (2,2)

Leviafan [203]

Answer:

Probability of having student's score between 505 and 515 is 0.36

Given that z-scores are rounded to two decimals using Standard Normal Distribution Table

Step-by-step explanation:

As we know from normal distribution: z(x) = (x - Mu)/SD

where x = targeted value; Mu = Mean of Normal Distribution; SD = Standard Deviation of Normal Distribution

Therefore using given data: Mu (Mean) = 510, SD = 10.4 we have z(x) by using z(x) = (x - Mu)/SD as under:

In our case, we have x = 505 & 515

Approach 1 using Standard Normal Distribution Table:

z for x=505: z(505) = (505-510)/10.4 gives us z(505) = -0.48

z for x=515: z(515) = (515-510)/10.4 gives us z(515) = 0.48

Afterwards using Normal Distribution Tables and rounding the values to two decimals we find the probabilities as under:

P(505) using z(505) = 0.32

Similarly we have:

P(515) using z(515) = 0.68

Now we may find the probability of student's score between 505 and 515 using:

P(505 < x < 515) = P(515)-P(505) = 0.68 - 0.32 = 0.36

PS: The standard normal distribution table is being attached for reference.

Approach 2 using Excel or Google Sheets:

P(x) = norm.dist(x,Mean,SD,Commutative)

P(505) = norm.dist(505,510,10.4,1)

P(515) = norm.dist(515,510,10.4,1)

Probability of student's score between 505 and 515= P(515) - P(505) = 0.36
