Let us first change these fractions into each other's equivalent fractions , so that we can order them from the smallest to the largest .
[tex] (i) \: \frac{1}{2} = \frac{(1 \times 3)}{6} [/tex]
[tex]\implies \color{olive} \frac{1}{2} = \color{hotpink} \frac{3}{6}[/tex]
[tex](ii) \: \frac{1}{3} = \frac{(1 \times 2)}{6} [/tex]
[tex]\implies\color{olive} \frac{1}{3} = \color{hotpink} \frac{2}{6} [/tex]
[tex](iii) \: \frac{5}{6} = \frac{(5 \times 1)}{6} [/tex]
[tex]\implies\color{olive} \frac{5}{6} = \color{hotpink} \frac{5}{6} [/tex]
Therefore, the fractions arranged in order from the least to the greatest :-
[tex] \bold\color{hotpink} { \color{olive} = \color{hotpink} \frac{1}{3}

Complete Question
Consider H0: μ=38 versus H1: μ>38. A random sample of 35 observations taken from this population produced a sample mean of 40.27. The population is normally distributed with σ=7.2.
Calculate the p-value. Round your answer to four decimal places.
Answer:
The [tex]p-value = 0.030742[/tex]
Step-by-step explanation:
From the question we are told that
The population mean is [tex]\mu = 38[/tex]
The sample size is n = 35
The sample mean is [tex]\= x = 40.27[/tex]
The standard deviation is [tex]\sigma = 7.2[/tex]
The null hypothesis is [tex]H_o[/tex]: μ=38
The alternative hypothesis is H1: μ>38
Generally the test statistics is mathematically represented as
[tex]t = \frac{ \= x -\mu }{\frac{\sigma }{ \sqrt{n} } }[/tex]
=> [tex]t = \frac{ 40.27 - 38 }{\frac{ 7.2 }{ \sqrt{ 35} } }[/tex]
=> [tex]t =1.87[/tex]
Generally from the z table the p-value of [tex](Z > 1.87 )[/tex] is
[tex]p-value = P(Z > 1.87) = 0.030742[/tex]
The solution to -2x/3 + 7< 15 is the set ? A x>-12 B x<-12 C x>33 D x<-10
Answer:
A. x>-12
Step-by-step explanation:
-2x/3+7<15 Subtract 7 on both sides.
-7 -7
-2x/3<8 -2x/3 is equal to -2/3x, so you can simplify to that.
-2/3x<8 Because you have to isolate x, multiply by the reciprocal of the
*-3/2 *-3/2 fraction. This will divide by -2/3 on both sides.
x>-12 Remember, because you multiplied by a negative, you have to flip the inequality sign.

calculate the rate of change in your neighborhood population of squirrels based on the data from a june 2015
The question is incomplete. Here is the complete question.
Scenario: You are bored during quarantine. However, you have been observing a bird feeder in your backyard and wow... do there seem to be a lot of squirrels in your neighbourhood. You begin to wonder how many squirrels are actually in your neighbourhood and devise an experiment to track their population.
Part 1. Using the data below, estimate the population of squirrels in your neighbourhood as if you employed the Mark-and-Recapture method. Please be sure to include any units in your final answer.
#captured on 06/01/20 10
#captured on 06/30/20 6
#recaptured on 06/30 from 06/01 3
Part 2. Calculate the rate of change in your neighbourhood population of squirrels based on the data from a June 2015 report that indicated a population of 40 squirrels.
Part 3. Calculate the intrinsic growth rate (r) for this population of squirrels based on the data you have acquired so far.
Part 4. Interpretations: In 1-2 sentences, summarize what's happening here (e.g. is the population growing or shrinking or staying the same?) and propose one plausible explanation for this change.
Answer: Part 1: Population of 20 squirrels
Part 2: Rate of change 50%
Part 3: r = -0.1386 anos
Step-by-step explanation: The Mark-and-Recapture method is a method to estimate a population when counting each individual is impractical. The method consists in capture a small population of individuals, mark them and released them back to the population. After a while, you catch another group and record the ones with the mark.
The calculations are made following this formula:
[tex]N=\frac{M*C}{R}[/tex]
N is the estimated population
M is marked individuals
C is total number of captured individuals (with and without the mark) the second time
R is recaptured individuals with the mark.
Part 1: Population of squirrels will be:
[tex]N=\frac{10*6}{3}[/tex]
N = 20
Population of squirrels in 2020 is 20 squirrels.
Part 2: Rate of change is calculated by the change in the population divided by the original population:
rate = [tex]\frac{20-40}{40}[/tex]
rate = - 0.5 or 50%
Part 3: The model for a population growth is exponential:
[tex]N=N_{0}e^{rt}[/tex]
N is population at that moment
N₀ is initial population
r is growth rate
t is period of time
Growth rate will be:
[tex]N=N_{0}e^{rt}[/tex]
[tex]20=40e^{5r}[/tex]
[tex]e^{5r}=0.5[/tex]
[tex]5r=ln(0.5)[/tex]
[tex]r=\frac{ln0.5}{5}[/tex]
[tex]r=-0.1386[/tex]
Growth rate (r) for the population of squirrels after 5 years is [tex]r=-0.1386[/tex] years.
Part 4: The growth rate has a negative sign, which means population is decreasing along the 5 years, so population is shrinking.
One possible explanation is the environment the population are in is lacking the squirrels primary need, i.e., squirrels' food source is diminishing, causing the population to decrease.

You need a 40% alcohol solution. On hand, you have a 350 mL of a 15% alcohol mixture. You also have 90%
alcohol mixture. How much of the 90% mixture will you need to add to obtain the desired solution?
You will need
mL of the 90% solution
Submit Question
Let x be the amount of 90% solution you will use.
You have 350 mL of a 15% alcohol solution, so it contains 0.15 • 350 mL = 52.5 mL.
For each mL of the 90% solution that you use, you would add 0.9 mL of alcohol. So in the new mixture, the volume would be (350 + x) mL, and its concentration needs to be 40% so that
((52.5 + 0.9x) mL) / ((350 + x) mL) = 0.4
Solve for x :
(52.5 + 0.9x) / (350 + x) = 0.4
(52.5 + 0.9x) / 0.4 = 350 + x
131.25 + 2.25x = 350 + x
1.25x = 218.75
x = 175
so you will need to use 175 mL of the 90% solution.

In a small city, approximately 15% of those eligible are called for jury duty in any one calendar year. People are selected for jury duty at random from those eligible, and the same individual cannot be called more than once in the same year. (a) What is the probability that a particular eligible person in this city is selected in both of the next 2 years
Answer:
0.0225
Step-by-step explanation:
Probability that an eligible individual is called for jury duty in any one calendar year = 15/100 = 0.15
a) What is the probability that a particular eligible person in this city is selected in both of the next 2 years
Probability that an eligible person is chosen in each of the next 2years:
P(being chosen in first year) * P(being chosen in second year)
Since the probability of being chosen is the same in any one year with a probability of 0.15
Hence,
P(being chosen in first year) * P(being chosen in second year)
0.15 * 0.15 = 0.0225
a. the probability that a particular eligible person in this city is selected in both of the next 2 years is 0.0225
Calculation of the probability:Since In a small city, approximately 15% of those eligible are called for jury duty in any one calendar year and there is two years.
So, the probability is
= 0.15 (0.15)
= 0.0225

a box has a square base of side x and height h find the dimensions x, h for which the volume is 14 and the surface area is as small as possible
Volume of cuboid :
[tex]14 = x^2h\\\\h = \dfrac{14}{x^2}[/tex]
Surface area of this cuboid :
[tex]A = 2( x^2 + xh + xh )\\\\A = 2( x^2 + 2xh)[/tex]
Putting [tex]h = \dfrac{14}{x^2}[/tex] in above equation, we get :
[tex]A=2(x^2 + 2x\times \dfrac{14}{x^2})\\\\A = 2( x^2 + \dfrac{28}{x} )[/tex]
For minimum area, [tex]\dfrac{dA}{dx}=0[/tex] :
[tex]\dfrac{dA}{dx}=2( 2x -\dfrac{28}{x^2})\\\\\dfrac{dA}{dx }= 4(x - \dfrac{14}{x^2})\\\\x - \dfrac{14}{x^2}=0\\\\x=\sqrt[3] {14} = 2.41[/tex]
Therefore, value of x is 2.14 .
Hence, this is the required solution.
The dimension for which the volume is 14 and the surface area is as small as possible are 2.41 by 2.41 by 2.41
The formula for calculating the volume of the square box is expressed as:
[tex]V = x^2h[/tex]
Given that the volume of the box is 14, on substituting the value we will have:
[tex]14 =x^2h\\h=\frac{14}{x^2}[/tex]
The surface area of the box is expressed as:
[tex]S = 2(x^2+xh+xh)\\S=2(x^2+2xh)\\S = 2(x^2+2x(\frac{14}{x^2} ))\\S = 2(x^2+\frac{28}{x} )\\S=2x^2+\frac{56}{x}[/tex]
To get the surface area is as small as possible, then dS/dx = 0
[tex]\frac{dS}{dx} = 4x-\frac{56}{x^2}\\0 = 4x-\frac{56}{x^2}\\4x = \frac{56}{x^2}\\4x^3 = 56\\ x^3=14\\x=\sqrt[3]{14}\\x= 2.41[/tex]
Get the height of the box. Recall that;
[tex]h=\frac{14}{x^2}\\h=\frac{14}{(2.41)^2}\\h=\frac{14}{5.8081}\\h= 2.41[/tex]
Hence the dimension for which the volume is 14 and the surface area is as small as possible are 2.41 by 2.41 by 2.41
