Answer:

Step-by-step explanation:

b and c are the speeds of the boat in stool water, and current, respectively.

Going with the current, the boat travels b+c=16 km/h.

Going against the current, the boat travels b-c=6 km/h

add the equations together

b+c = 16

b-c = 6

—————

2b = 22

b = 11

c = 16-b = 5

Solving equations with variables on both sides <br><br><br> 7+9x=6x-2
katrin2010 [14]

Answer:

Here

Step-by-step explanation:

We move all terms to the left:

7+9x-(6x-2)=0

We get rid of parentheses

9x-6x+2+7=0

We add all the numbers together, and all the variables

3x+9=0

We move all terms containing x to the left, all other terms to the right

3x=-9

x=-9/3

x=-3

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%
