Hello : the system is :
<span> y= -2x+4 ...(1)
y= x² +4x+13....(2)
x²+4x+13 = -2x+4
x²+6x+9=0
(x+3)² =0
x+3=0
x= -3 
subsct in (1) : y=-2(-3)+4 =10</span>

The number of peanuts in bags is normally distributed with a mean of 184.7 peanuts
ioda

Standard deviation = 3.3

The data point = 178

The mean = 184.7

<h2>Further Explanation</h2>

To calculate the Z-score of a bag containing 178 peanuts, we should use the formula to calculating a z-score.

The formula for calculating a Z-score is as follows

z = \frac{data Point - Mean}{Standard Deviation}

This also implies

z = \frac{178 - 184.7}{3.3}

Z= -2.03

therefore, the correct answer is -2.03

A z-score determine the number of standard deviation from the mean a data point is.

some important factors about z-score include:

  • if it is a positive z-score, it indicates the data point is above average
  • if it is a negative Z-score, it indicates the data point is below average
  • if the z-score is close to 0, it then means the data point is close to average
  • if the z-score is above 3 or below -3, it is considered to be unusual

Let f ( x ) = 10 x + 14 f − 1 ( x ) =
Agata [3.3K]

Answer:

  f^-1(x) = (x -14)/10

Step-by-step explanation:

You can find the inverse function by solving for y:

  x = f(y)

Here, that is ...

  x = 10y +14 . . . . . use the definition of f(y)

  x -14 = 10y . . . . . . subtract 14

  (x -14)/10 = y . . . . divide by the coefficient of y

So, your inverse function is ...

  f^-1(x) = (x -14)/10
