Recognize situations that require decision making. identifying and developing alternative courses of action; evaluating alternatives; choosing one of the alternatives and carrying out the chosen steps.
Quantitative decisions are primarily based on statistical analysis of collected data, whereas qualitative decisions are based on many algorithms such as data type and quality, factors influencing collected data, and risk assessment. It is based on more than just numeric data values to make decisions.
Quantitative factors are the basis of numerical determination.

A "necklace" is a circular string with several beads on it. It is allowed to rotate a necklace but not to turn it over. How many different necklaces can made using 13 different beads?.
479,001,600 necklaces can be made using 13 different beads.
We will be using 13 different beads in our necklace, and the arrangement of the beads is what distinguishes one necklace from another.
Additionally, the mirrored necklaces are different because we are unable to turn the necklaces around (the positions of the beads are mirrored)
We have 13 alternatives for the first bead, 12 options for the second, and so on.
if the product of the options for each choice results in a total number of combinations equal to 1, then we have:
Combinations of the form C=13*12*11*10*9*8*7*6*5*4*3*2*1
C = 6,227,020,800.
Now that the necklace may be rotated, a combination is possible.
A B C D E F G H I J K L M (Each letter corresponds to a certain bead)
is identical to other orders as
A through Z: m A B C D E F G H I J K L
With 13 rotations for each combination, the actual number of combinations is:
C/13 = 6,227,020,800/13 = 479,001,600

how much time is required for a 5.75 mgmg sample of 51cr51cr to decay to 0.700 mgmg if it has a half-life of 27.8 days? express the time in days to one decimal place.
The time is required for a 5.75 mg sample of 51cr to decay to 0.700 mg is 99.4 days
What is decay constant?
A property of unstable radionuclides that spontaneously decay at various rates to a more stable atomic configuration is the radioactive decay constant (λ); The higher the decay constant, the faster the parent radionuclide depletes over time.Decay constant k = ln(2) / half life
= ln(2) / 27.8
= 0.024933 day⁻¹
For first order decay:
ln(M / M₀) = -kt
where M is mass remaining at time t and M₀ is initial mass.
ln(0.700/5/75) = -0.024933 * t
Time, t = 99.4 days
Hence, time is required for a 5.75 mg sample of 51cr to decay to 0.700 mg is 99.4 days.

Step-by-step explanation:
before starting to paint, bill had 130130 ounces of blue paint, 164164 ounces of red paint, and 188188 ounces of white paint. bill painted four equally sized stripes on a wall, making a blue stripe, a red stripe, a white stripe, and a pink stripe. pink is a mixture of red and white, not necessarily in equal amounts. when bill finished, he had equal amounts of blue, red, and white paint left. find the total number of ounces of paint bill had left.
The weight in ounces of paint which left after painting the wall is 114 ounces.
Explain weight in ounces.1 ounce is equivalent to 437.5 grains or 28.349 grams Abbreviation: oz. a unit of weight equivalent to one twelfth of a Troy or Pharmacists' pound; 1 ounce is equivalent to 480 grains or 31.103 grams. short for liquid ounce. a little part or sum.
How we make the equation of this problem to solve it?Let x be how much paint in a strip. The aggregate sum of paint is 130+164+188=482. In the wake of painting the wall, the aggregate sum of paint is 482-4x. Since the aggregate sum in each tone is similar in the wake of getting done.
Then equation can be written as,
482 - 4x/3 = 130 -x
482 - 4x = 390 - 3x
x = 92
so, the paint left = 482-4x = 482 - 4(92) = 114.

Find the slope of the line passing through the points (-7, 5) and (5, 5).

Step-by-step explanation:
Slope is "rise over run" or change is y values divided by change in x values
the change is x values is zero. 8-8=0. Anything divided by zero is infinity.
the slope is infinite. The line connecting the 2 points is a vertical line, x=8.
Vertical lines have infinite slope.
the r value is 0.2 per year. what percentage growth rate would the population show in the absence of constraints? (round your answer to the nearest whole number.)
The percentage growth rate would the population show in the absence of constraints is 22%
A logistic model is modeled by the function
N = K/1+be^rt
where, the constant k represents carrying capacity,
the constant b is formed by b = k/n(o) - 1
the value of r will be the intrinsic exponential growth rate and t represent time.
⇒ If there is no limiting factors, then the logistic model would be exponential according to formula:
N = N(0)e^rt
Since the corresponding growth factor for this exponential function is a = e^r
so the variable r can be obtained from a using :
r = ln a
a = e^r
given r= 0.2
a = ?
a = e°·²
a = 1.221
a = 1.22
⇒ 1.22 - 1 = 0.22
0.22×100 = 22%
Hence we get the percentage growth as 22%.

Write a symbolic equation for the location of the center of mass of the three beads relative to the center bead, in terms of the variables given in the problem statement.
The symbolic equation for the location of the center of mass of 3 beads is [tex]x_{cm}[/tex] = m1d1 + m2 (d1 + d2) + m3 ( d1+d2+d3)/ m1 + m2 + m3
Mass of 1st bead = m1 = 22 g
Mass of the 2nd bead = m2 = 12 g
Mass of the 3rd bead = m3 = 51 g
Distance of the 1st bead from left end of the rod = d1 = 1.5 cm
Distance of the 2nd bead from the first bead = d2 = 1.9 cm
Distance of the 3rd bead from the second bead = d3 = 4.5 cm
Location of the center of mass of the three beads relative to the left end of the rod = xcm
We want to find the center of mass relative to the left end of the rod therefore we will need the distances of each bead from the left end of the rod.
Distance of the first bead from the left end of the rod = x1
x1 = d1
Distance of the second bead from the left end of the rod = x2
x2 = d1 + d2
Distance of the third bead from the left end of the rod = x3
x3 = d1 + d2 + d3
[tex]x_{cm}[/tex] = m1 x1 + m2 x2 + m3 x3 / m1 + m2 + m3
[tex]x_{cm}[/tex]= m1(d1) + m2(dı + d2) + m3(d1 + d2 +d3)/ m1 + m2 + m3
[tex]x_{cm}[/tex] = m1d1 + m2 (d1 + d2) + m3 ( d1+d2+d3)/ m1 + m2 + m3
Substituting the values to get a numerical answer,
[tex]x_{cm}[/tex] = (22)(1.5) + (12)(1.5 +1.9) + (51)(1.5 +1.9 +4.5) 22 + 12 + 51
xcm = 5.61 cm
Location of the center of mass of the three beads relative to the center bead = x
Distance of the first bead from the center bead (second bead) = x4
x4 = -d2 (Negative as it is to the left of the second bead)
Distance of the second bead from the center bead (second bead) = x5 = 0 cm
Distance of the third bead from the center bead (second bead) = x6
x6 = d3
x = m1 x4 + m2 x5 + m3 x6/ m1 + m2 + m3
x = m1 ( - d2) + m2 (0) + m3 (d3) / m1 + m2 + m3
x = - m1 d2 + 0 + m3d3 / m1 + m2 + m3
x = m3d3 - m1 d2 / m1 + m2 + m3
Substituting the values to get a numerical answer,
x= (51) (4.5) - (22)(1.9)/22 + 12 + 51
x = 2.21 cm
