What is the inverse of the function? f(x) = 2x - 10?

gulaghasi [49]

Answer:

Step-by-step explanation:

Let $f(x)=y$

y=2x-10

Switch x and y,

x=2y-10

x+10=2y

(x/2)+5=y

So $f^{-1}(x)=\frac{x}{2}+5$

Please math , help

Furkat [3]

Answer:

As both the mean and standard deviation are in the desired ranges, the tool passes the technical control.

Step-by-step explanation:

Mean of the batch:

The mean of the batch is the sum of all values divided by the number of items. So

$M = \frac{199+204+201+197+195+204+200}{7} = 200$

Mean in the desired interval.

Standard deviation:

Square root of the sum of the difference squared between each term and the mean, divided by the number of items. So

$S = \sqrt{\frac{(199-200)^2+(204-200)^2+(201-200)^2+(197-200)^2+(195-200)^2+(204-200)^2+(200-200)^2}{7}} = 1.18$

As both the mean and standard deviation are in the desired ranges, the tool passes the technical control.
