The science teacher gives daily homework. For a random sample of days throughout the year, the median number of problems is 5 and the IQR is 2. The Spanish teacher also gives daily homework. For a random sample of days throughout the year, the median number of problems is 10 and the IQR is 1. If you estimate the median number of science homework problems to be 5 and the median number of Spanish problems to be 10, which is more likely to be accurate? Explain your reasoning.

Answers

Answer 1

Answer:

SCIENCE SEEMS MORE ACCURATE

Step-by-step explanation:

The interquartile range (IQR) = difference between the upper and lower quartile (Q3 - Q1)

The median can be estimated as :

(Q3 - IQR/2) or (Q1 + IQR/2).

FOR SCIENCE:

MEDIAN NUMBER = 5

IQR = 2

IQR = Q3 - Q1

Q3 = median + IQR/ 2 = 5 + 2/2 = 6

Q1 = median - IQR/2 = 5 - 2/2 = 4

FOR SPANISH:

MEDIAN = 10

IQR = 1

IQR = Q3 - Q1

Q3 = median + IQR/ 2 = 10 + 1/2 = 10.5

Q1 = median - IQR/2 = 10 - 1/2 = 9.5

Science has a lower median score and an interquartile range which is reasonable wider than Spanish with a larger median value (but a very narrow interquartile range).

Step-by-step explanation:

[tex]\frac{3}{5} +\frac{1}{4} +\frac{3}{8} =[/tex] Distance Janie walked

First add [tex]\frac{1}{4} and\frac{3}{8}[/tex] canvert 1/4 by multiplying by 2/2 to get a commmon denominator.

[tex]\frac{1}{4} *\frac{2}{2} =\frac{2}{8}[/tex]

[tex]\frac{2}{8} +\frac{3}{8} =\frac{5}{8}[/tex]

Now find a common denominator for 3/5 and 5/8 by multiplying 3/5 by 8/8  and 5/8 by 5/5.

[tex]\frac{3}{5}*\frac{8}{8}=\frac{24}{40}[/tex]

[tex]\frac{5}{8}*\frac{5}{5}=\frac{25}{40}[/tex]

Now add them.

[tex]\frac{24}{40}+\frac{25}{40}=\frac{49}{40}=1\frac{9}{40}[/tex]miles

You can also convert all to decimals and add.

3/5 = .6

1/4 = .25

3/8 = .375

.6 + .25 + .375 = 1.225

Also 1 [tex]\frac{9}{40}[/tex] = 1.225

ben is training for a triathlon he runs 1/5 of a mile in 1/20 of an hour he seems to third of a mile in 1/9 of an hour he bikes for miles in 1/4 of an hour at this rate how many minutes does it take them to run 2 miles swim 2 miles in bike 8 miles

Answers

Answer:

a) He will take 76 minutes in the triathlon

Step-by-step explanation:

He runs  1/5 of a mile in 1/20 f hour then, by simple inspection

1/5    ⇒    1/20       then    1/5 miles* 10    = 2 miles

                                        1/20*hours*10    = 1/10 hours

10/10 of an hour is 60 minutes

1/10 of an hour is 6 minutes

swimming

1/3 of a mile in 1/9 of hours then

1/3mile *6   = 2 miles

1/9 of an hour * 6 = 6/9 hours  or 2/3 of an hour

3/3 of an hour is 1 hour   = 60 minutes

2/3 of an hour is    =  40 minutes

In bike

4 miles  in  1/4 hour   then

4 miles *2   = 8 miles

1/4 hour* 2  =  1/2 hour = 30 minutes

Then he will do the triathlon in:

6 minutes running

40 minutes swimming

30 minutes in bike

Total 76 minutes

Among involved people, 5 percent experience a breakup of their relationship every month. Among uninvolved people, 10 percent enter into a relationship every month. What is the steady-state percentage of residents who are uninvolved

Answers

Answer:

The steady-state percentage of residents who are uninvolved = 0.33%

Step-by-step explanation:

This is an example of the natural rate of unemployment given the steady-state percentage of residents who are uninvolved in the question. From the question, the break-up rate represents the rate of job separation in the natural rate of unemployment, while the rate that enters into a relationship represents the rate of job finding in the natural rate of unemployment.

The formula for the natural rate of unemployment = U/L = s / (s + f)

So, the steady-state percentage of residents who are uninvolved = U/L = s / (s + f)

Where U/L = natural rate of unemployment

               s = rate of job separations

             f = rate of job finding

s = 5 percent

f = 10 percent

The steady-state percentage of residents who are uninvolved

=  5% / (5% + 10%)

= 0.33%

Answers

Answer:

x = 9°

y = 119°

Step-by-step explanation:

Given,

y° = 61°+58° { the exterior angle formed by producing the side of triangle is equal to two non-adjacent angle}

or, y° = 119°

therefore, y° = 119°

Now,

52°+y°+x° = 180°{the sum of angle if triangle is 180°}

or, 52°+119°+x°= 180°

or, 171°+x° = 180°

or, x° = 180°-171°

or, x° = 9°

therefore, x° = 9°

Perfect Purple Water The recipe for Perfect Purple Water says, "Mix 8 ml of blue water with 3 ml of red water." lada mixes 24 ml of blue water with 9 ml of red water. Andre mixes 16 ml of blue water with 9 ml of red water. . Which person will get a color mixture that is the same shade as Perfect Purple Water? Explain or show your reasoning.​

Answers

Analysing the question:

We are given that the ratio between the blue and red color is 8 : 3

as long as the volumes of the colours added simplify to 8 : 3 , the color will be Perfect Purple

Lada's Solution:

Lada mixed 24 mL of blue water with 9 mL of red water

we will try to simplify this ratio:

24:9 = 24 / 9

8 / 3

8 : 3

Hence, the ratio of the colours in Lada's mixture is correct. So, Lada will get perfect purple water

Andre's Solution:

Andre mixed 16mL of Blue water with 9 mL of red water

we will try to simplify this ratio:

16 : 9 = 16 / 9

THIS RATIO CANNOT BE SIMPLIFIED

Hence, the ratio of blue and red color in Andre's mixture is 16 : 9

but the ratio for a perfect purple color is 8 : 3

Since the ratio in Andre's mixture is incorrect, she will NOT get the perfect purple colour

Answer:

Lada will get a color mixture that is the same shade as Perfect Purple Water.

Step-by-step explanation:

Proportions

The mix for Perfect Purple Water contains 8 ml of blue water with 3 ml of red water.

The exact proportion of both ingredients is, blue to red:

[tex]\displaystyle \frac{8}{3}[/tex]

Lada mixes 24 ml of blue water with 9 ml of red water. The proportion is:

[tex]\displaystyle \frac{24}{9}[/tex]

Simplifying by 3:

[tex]\displaystyle \frac{8}{3}[/tex]

The proportion obtained by Lada is the same shade as Perfect Purple Water.

Andre mixes 16 ml of blue water with 9 ml of red water, his proportion is:

[tex]\displaystyle \frac{16}{9}[/tex]

This fraction cannot be reduced and its result is not exactly the same as the perfect required proportion.

Thus, Lada will get a color mixture that is the same shade as Perfect Purple Water.

For a polynomial P(x), the quotient P(x)/(x-2) has a remainder of 12. What is the value of P(2)? Please explain. Thanks :)

Answers

Answer:

12

Step-by-step explanation:

P(x) has infinitely many solutions, but I am going to find the easiest one, which would be a linear equation.

First, notice that x-2 perfectly divides into itself.

Then, if you add 12 to x-2, you will end up with a remainder of 12. Therefore, P(x) would be x-2+12 = x+10.

Now that we know P(x), we can directly plugin 2 to find out P(2):

2+10 = 12

Therefore, P(2) = 12.

C =

Answers

Answer:

C = 0.65M+19.65

Step-by-step explanation:

Given the the standard charge S (in dollars) given by the function

S = 0.40M + 15.75, where M is the number of miles driven.

Also the insurance charge I (in dollars) is given by the function

I = 0.25M + 3.90

If C is the total charge (in dollars) for a rental that includes insurance, then:

C = S + I

Substitute the given function into the expression:

C = 0.40M + 15.75 + 0.25M + 3.90

Collect like terms

C = 0.40M+0.25M+15.75+3.90

C = 0.65M+19.65

Hence an equation relating C to M is expressed as C = 0.65M+19.65
