Answer:

In chemistry, the acidity of a solution is measured using the pH scale 0-14. A solution that's pH 3 is 10 times more acidic than a solution that's pH 4. The lower the pH the more acidic something is. The higher the pH the more basic something is. Water is generally around pH 7 (calculated using logarithms)

Also, in seismology. <span>Vibrations are picked up and plotted on a seismograph. The strength, or magnitude, of an earthquake is measured using the Richter scale. The Richter scale is numbered 0-10.

Computations For CC for Fraction defective

Sample No  d  p=d/100

1                    0       0

2                    0      0

3                    2     0.02

4                     1     0.01

5                     0      0

6                     1      0.01

7                     2      0.02

8                     0        0

                 Total   0.06

\overline{p} =\frac{1}{k}\sum p=\frac{0.06}{8} =0.0075

\overline{q} =1- 0.0075= 0.9925

3 sigma control limits for p chart are given by:

\overline{p} \pm 3\sqrt{\overline{p}\overline{q}/n}\Rightarrow 0.0075\pm 3\sqrt{\frac{0.0075*0.9925}{100}}

= 0.0075\pm0.0259\Rightarrow ( 0.0334,0 )

hence option e is correct

Help please 25 pts. I will mark. One month Justin rented 2 movies and 5 video games for a total of $32. The next month he rented
umka21 [38]

Answer:

The movie costs $3.50 and the video games cost $5.

Step-by-step explanation:

a = 1 movie

b = 1 video game

2a + 5b = $32

8a + 3b = $43

2a x -4 = -8a

5b x -4 = -20b

32 x -4 = -128

   8a + 3b = $43

-   8a + 20b = $128

--------------------------------

-17b = -85

17b = 85

/17     /17

b = 5

2a + 5(5) = 32

2a + 25 = 32

-       25 = -25

----------------------

2a = 7

/2 = /2

a = 3.5

a = $3.50

b = $5
