Answer:

upper control limit = 13.34

Step-by-step explanation:

The c-chart is used to check the change in the number of recorded calls per day

First find out the center line

c = sum of recorded calls/number of days

c = (3 + 0 + 8 + 9 + 6 + 7 + 4 + 9 + 8)/9

c = 54/9

c = 6

The upper control limit for 3σ is

upper control limit = c + 3√c

upper control limit = 6 + 3√6

upper control limit = 13.34

Therefore, the upper control limit for the 3-sigma c-chart is 13.34.

Answer: 1/6

Step-by-step explanation:

<u>Given:</u>

4/9 and 11/18

<u>Solve:</u>

<em>STEP ONE: Make the denominators equal by determining the LCM</em>

LCM = Least Common Multiple

First Five multiples of 9 = 9, 18, 27, 36, 45

First FIve multiples of 18 = 18, 36, 54, 72, 90

As we can see from the list above, both 18 and 36 overlap, however, 18 is less than 36. Therefore, 18 is the LCM.

<em>STEP TWO: Compare the size and determine the greater one.</em>

4/9 = (4 × 2) / (9 × 2) = 8/18

11/18 = 11/18

Since 11 > 8, therefore, 11/18 is greater than 8/18

<em>STEP THREE: Find the difference between the two fractions.</em>

 11/18 - 4/9

=11/18 - 8/18

=(11 - 8) / 18

= 3 / 18

= 1/6

Hope this helps!! :)

Angle A and B are supplementary angles. The measure of angle B is twice the measure of angle A minus 24. Find the measure of the
ivann1987 [24]

Answer:

A = 58

B = 112

Step-by-step explanation:

A + B = 180                           Supplementary angles

B = 2A - 24                           Given

Substitute for B in the first equation

A + 2A - 24  = 180

3A - 24 = 180                         Add 24 to both sides

3A = 180 + 24                        Combine the right

3A = 204                               Divide both sides by 3

A = 204/3

A = 68

B = 2A - 24

B = 2*68 - 24

B = 136 - 24

B = 112
