Answer:

g(- 1) = -2

Step-by-step explanation:

Given the rational function, g(x) = - \frac{21 + x}{10}:

In order to evaluate and find the value of g(-1), simply substitute the input value into the given function.

g(x) = - \frac{21 + x}{10}

g(-1) = - \frac{21 - 1}{10}

g(-1) = - \frac{20}{10}

g(-1) = -2

Therefore, the output value when g(- 1) is: g(- 1) = -2.

A textile mill wishes to establish a control procedure on flaws in towels it manufactures. Using an inspection unit of 50 units,
Natasha_Volkova [10]

Answer:

•A c-chart is the appropriate control chart

• c' = 8.5

• Control limits, CL = 8.5

Lower control limits, LCL = 0

Upper control limits, UCL = 17.25

Step-by-step explanation:

A c chart is a quality control chart used for the number of flaws per unit.

Given:

Past inspection data:

Number of units= 100

Total flaws = 850

We now have:

c' = 850/100

= 8.5

Where CL = c' = 8.5

For control limits, we have:

CL = c'

UCL = c' + 3√c'

LCL = c' - 3√c'

The CL stands for the normal control limit, while the UCL and LCL are the upper and lower control limits respectively

Calculating the various control limits we have:

CL = c'

CL = 8.5

UCL = 8.5 + 3√8.5

= 17.25

LCL = 8.5 - 3√8.5

= -0.25

A negative LCL tend to be 0. Therefore,

LCL = 0

There are 120 people on the bus 50% get off at the first stop 20% get off at the second stop. The rest get off on the third stop
erastova [34]

Answer:

48 people

Step-by-step explanation:

First, find how many were left after the first stop:

120(0.5)

= 60

Find how many were left after the second stop:

60(0.8)

= 48

So, since the rest got off on the third stop, this means 48 people got off on the third stop.

There are some people on a train
Kitty [74]
<h3>Answer:  62</h3>

======================================================

Explanation:

18 people get off, and 21 get on

We can write the 18 as -18 to indicate a loss of 18 people. The 21 as +21 to mean we gained 21 people.

The net change is -18+21 = +3 or simply 3.

After the first stop, 3 more people are on the train compared to before reaching this stop.

If x is the number of people before the stop, then x+3 is the number of people after the stop. Set this equal to 65 and solve for x.

x+3 = 65

x = 65-3

x = 62 people were on the train to begin with.

-----------

Check:

62 people to start off

62-18 = 44 people after the 18 people get off

44+21 = 65 people after the 21 new people get on

The answer is confirmed.
