Answer:

(2,-9).

Step-by-step explanation:

It is given that the x-axis is the perpendicular bisector of the line segment joining the points (2,9) and (x,y).

It means x-axis is the line of reflection and (x,y) is the image of (2,9) across the x-axis.

Rule of reflection is

(x,y)\to (x,-y)

(2,9)\to (2,-9)

The point (2,-9) is the mirror image of (2,9) across the x-axis.

Therefore, the point (x,y) is (2,-9).

pH measurements of a chemical solutions have mean 6.8 with standard deviation 0.02. Assuming all pH measurements of this solutio
aalyn [17]

Answer: 2.14 %

Step-by-step explanation:

Given : pH measurements of a chemical solutions have

Mean :  \mu=6.8

Standard deviation : \sigma=0.02

Let X be the pH reading of a randomly selected customer chemical solution.

We assume  pH measurements of this solution have a nearly symmetric/bell-curve distribution (i.e. normal distribution).

The z-score for the normal distribution is given by :-

z=\dfrac{x-\mu}{\sigma}

For x = 6.74

z=\dfrac{6.74-6.8}{0.02}=-3

For x = 6.76

z=\dfrac{6.76-6.8}{0.02}=-2

The p-value =P(6.74

P(z

In percent, 0.0214\times=2.14\%

Hence, the percent of pH measurements reading below 6.74 OR above 6.76 = 2.14%

Eight less than a number doubled is twenty more than the number. What is the number?
m_a_m_a [10]
Let the number be a .... =>Number doubled : 2a .. =>Eight less than the no. Doubled : 2a - 8 =>Eight less than the no. doubled is 20 more than the no. : 2a - 8 = 20 + a =>2a - 8 - 20 - a = 0 =>2a -a - 20 -8 = 0 =>a -28 = 0 =>a = 28 =>so the number is 28... Hope it helps!!!
