Ima Neworker requires 30 minutes to produce her first unit of output. If her learning curve rte is 65%, how many units will be p

Vilka [71]

Answer:

Approximately 18 units will be produced before the output rate exceeds 12 units per hour.

Step-by-step explanation:

The learning curve formula is given by:

$Y = aX^{b}$

In which:

Y is the average time per unit.

X is the cumulative number of units produced.

a is the time required to produe the first unit

b = log of learning rate/log 2

In our problem, we have:

Y = 12 units per hour. We are working in minutes, what is the average time per unit?

60 minutes - 12 units

Y minutes - 1 unit

$12Y = 60$

$Y = 5$

So Y = 5.

X is the value we want to find

a = 30

b = $\frac{log 0.65}{log 2}=-0.6215$

$Y = aX^{b}$

$5 = 30X^{-0.6215}$

$\frac{1}{6} = \frac{1}{X^{0.6215}}$

$X^{0.6215} = 6$

$\sqrt[0.6215]{X^{0.6215}} = \sqrt[0.6215]{6}$

$X = 17.86$

Approximately 18 units will be produced before the output rate exceeds 12 units per hour.

One number has three significant figures and another number has four significant figures. If these numbers are added, subtracted

d1i1m1o1n [39]

Answer:

Addition

Step-by step explanation:

Let a=5.54 and b=5.566

a+b=5.54+5.566=11.106

Using significant rule of addition

a+b=11.11(4 significant figures)

b-a= 0.026

Using significant rule of subtraction

b-a=0.03(Two significant figures)

$a\times b=5.54\times 5.566= 30.83564$

Using significant rule of multiplication

$a\times b=30.8$ (3 significant figures)

$\frac{b}{a}=\frac{5.566}{5.54}=1.00469$

Using significant rule of division

$\frac{b}{a}=1.00$ (Three significant figures)

Addition can produce the greatest number of significant figures
