4(x + 2) = {h(n)}^{- 1}

Answer: 4/(n+2)

h(n)=4/n-2

Let y=h(n),then,

→y=4/n-2

→4/n=y+2

→n=4/(y+2)

Interchanging the role of y and n here to find inverse,

y=4/(n+2)  →inverse function

i.e. , inverse of h(n)=4/(n+2)

if alisson worked the times in the table and makes $9.32 an hour, how much was her gross pay this week
LenaWriter [7]
Hrs worked = 9.25 + 8.75 + 9 + 8.25 + 9 = 44.25 hrs. (44.25 - 40 = 4.25 hrs overtime) 
<span>40 hrs * $9.32 = $372.80 (Straight time) </span>

<span>$9.32 * 1.5 = $13.98 (Overtime rate) </span>
<span>4.25 (Overtime hrs.) x $13.98 (Overtime rate) = $59.42 (Overtime pay) </span>

<span>$372.80 + $59.42 = $432.22 (Total gross pay)</span>

If a normal distribution has a mean of 104 and a standard deviation of 6, what
Mademuasel [1]
<h3>Answer:  2</h3>

======================================

Explanation:

The greek letters mu and sigma represent the population mean and population standard deviation respectively.

mu = 104

sigma = 6

x = 116 is the raw score we want to convert to a z score

z = z score

z = (x-mu)/(sigma)

z = (116-104)/(6)

z = 12/6

z = 2

The positive z score tells us the raw score is above the mean.

A line whose equation is 3/2y =3x-6 is parallel to a line with a general equation ax+by+c=0 passing through the points (3,2) . F
lana66690 [7]

Answer:

\frac{1}{6} x+3y+\frac{13}{2}    or    x + 18y + 39

Step-by-step explanation:

\frac{3}{2} y = 3x-6

→ First multiply everything by 2 to get rid of the fraction

3y = 6x - 12

→ We want to find the equation that's parallel to this line and passes through (3 , 2). The first thing we know about parallel lines is that the gradient is the negative reciprocal so,

3y = -\frac{1}{6} x+c

→ Now we substitute in the values (3 , 2)

6 =- \frac{1}{2}+c

→ Add  \frac{1}{2}  to both sides to isolate c

\frac{13}{2} =c

So the equation of the line that is parallel to  \frac{3}{2} y = 3x-6  is  3y =- \frac{1}{6} x+\frac{13}{2}      but we are not finished we are asked to but the equation in the format

ax + by + c = 0  so,

3y =- \frac{1}{6} x+\frac{13}{2}

Rearrange

\frac{1}{6} x+3y+\frac{13}{2}

If the question want's the answer in whole numbers then multiply everything by 6

x + 18y + 39
