Answer:

y=(x+4)/12

Step-by-step explanation:

f(x)=12x-4

To find the inverse follow these steps:

1.) Make f(x) y so y=12x-4

2.) Switch x and y

so, x=12y-4

3.) solve for y

add 4 to the other side and then divide by 12 to get y by itself.

A list of measurements in increasing order is 4, 5, 6, 8, 10, and x. If the median of these measurements is 6/7 times their arit

igomit [66]

Answer:

The value of x would be 16.

Step-by-step explanation:

In a data,

Median : middle value of the data when the data is written is ascending order.

While,

$\text{Average}=\frac{\text{Sum of all observations}}{\text{Number of the observations}}$

Here, the given data is,

4, 5, 6, 8, 10, and x

So, median = = = 7.

Number of the observations = 6,

Sum of the observations = 4+ 5+6+8+10+x = 33 + x

Thus,

Average = $\frac{33+x}{6}$

According to the question,

$\frac{33+x}{7}=7$

$33+x=49$

$x=49-33$

$x=16$

Therefore, the value of x would be 16.
