Answer: 74.8%
This answer is approximate.
The value is rounded to the nearest tenth of a percent.
==========================================
Explanation:
Let,
X = area of the larger circle
Y = area of the smaller circle
Z = area of the shaded region = X - Y
The goal is to compute the ratio Z/X to get the answer we want
Let's find area of the larger circle
Area of circle = pi*(radius)^2
A = pi*r^2
X = pi*8.01^2
X = 64.1601pi
This is the exact area in terms of pi
Now repeat for the smaller circle
A = pi*r^2
Y = pi*4.02^2
Y = 16.1604pi
Subtract those results to find the value of Z
Z = X-Y
Z = 64.1601pi-16.1604pi
Z = 47.9997pi
This is the exact area of the red donut region
Divide Z over X to get the probability of landing in the red region
Z/X = (47.9997pi)/(64.1601pi)
Z/X = (47.9997)/(64.1601) <--- note how the pi terms cancel
Z/X = 0.74812 which is approximate
Convert to a percent
Move the decimal point 2 spots to the right
0.74812 ---> 74.812%
Then round this to one decimal place
74.812% ---> 74.8%

Answer:
- A. Paired-sample t-test. --- Wilcoxon Signed-Ranks T test
- B. Independent-sample t-test. --- Mann-Whitney U test
- C. One-way ANOVA, independent samples. --- Kruskal-Wallis H test
- D. One-way ANOVA, repeated measures. --- Friedman test
Step-by-step explanation:
- The nonparametric statistics is a branch of statistics, that seeks out the population distribution that is either being distributed freely or specifically.
- Wilcoxon Signed-Ranks T-test is a hypothesis test used to compare the two or pre related columns that can be matched and maybe a repeated measure on a single sample.
- The Mann-Whitney U test is a null hypothesis and states the probability of a random sample of X and Y from the population is greater than the X and that Y is greater than X.
- Kruskal-Wallis H test is a test of one variance analysis and tests that sample originates from the same distribution.
- The Friedman test is used to find treatment across multiple tested attempts. It involves the ranking of the rows and then considering the values of the column.
Answer:
La oferta 2 oferce el mayor valor final. Es la que debería ser aceptada.
Step-by-step explanation:
Dada la siguiente información:
Oferta 1:
$150.000 hoy y $200.000 dentro de 10 años.
Oferta 2:
$30.000 al final de cada uno de los próximos 10 años.
Tasa de interés= 14%
<u>Para decidir cuál de las dos ofertas es mejor, debemos calcular el valor final:</u>
<u>Oferta 1:</u>
VF= VP*(1+i)^n
VF= 150.000*(1,14^10) + 200.000
VF= $2.261.523,48
<u>Oferta 2:</u>
VF= {A*[(1+i)^n-1]}/i
A= cash flow anual
VF= {30.000*[(1,14^20) - 1]} / 0.14
VF= $2.730.747,83
