Answer:

5 mi  1432 yds

Step-by-step explanation:

   8mi 200 yds

- 2 mi 528 yds

---------------------------

We have to borrow 1 mile and convert to yards

1 mile = 1760 yds

 7mi 200+1760 yds

- 2 mi 528 yds

---------------------------

 7mi  1960 yds

- 2 mi 528 yds

---------------------------

5 mi  1432 yds

Answer:

8mi 200yds - 2mi 528yds

= 5mi 1432yds

Step-by-step explanation:

1 mile = 1760 yards

8 miles = 7miles + 1 mile = 7 miles + 1760 miles = 7 miles 1760 yards

8miles 200 yards = 7miles + 1760 yards + 200 yards = 7miles + 1960 yards

then:

8mi 200 yds - 2 mi 528 yds = 7mi 1960yds - 2mi 528yds

 7mi 1960yds

- 2mi   528yds

= 5mi  1432yds

Answer:

Suppose Jenna drives 41 miles on Monday. The Z-score when x - 41 is    [tex]-0.943[/tex].   The mean is  [tex]46[/tex]  This z-score tells you that x = 41 is  [tex]0.94[/tex]  standard deviations to the left of the mean.

Step-by-step explanation:

From the question we are told that

  The  mean is  [tex]\= x = 46\ miles / day[/tex]

  The standard deviation is  [tex]\sigma = 5.3 \ miles \ per \ day[/tex]

   The  value of =  41

Generally the z-score is mathematically represented as

        [tex]z = \frac{x-\= x}{\sigma }[/tex]

substituting values  

         [tex]z = \frac{41-46}{5.3}[/tex]

          [tex]z = - 0.943[/tex]

Answer:

a

  [tex]S.E = 0.05[/tex]

b

 [tex]P(P > 0.75) = 0.0013499[/tex]

Step-by-step explanation:

From the question we are told that

      The population  [tex]p = 0.60[/tex]

       The  sample size is  [tex]n = 96[/tex]

       The  sample proportion is  [tex]\r p = 0.75[/tex]

Generally the standard error is mathematically represented as

      [tex]S.E = \sqrt{ \frac{p(1-p)}{n } }[/tex]

substituting values    

       [tex]S.E = \sqrt{ \frac{0.60 (1-0.60 )}{96 } }[/tex]

       [tex]S.E = 0.05[/tex]

The  probability that  more  than  75% of consumers will indicate they like the drink is mathematically represented as

       [tex]P(P > 0.75) = P(\frac{\r P - p }{\sqrt{\frac{p(1-p)}{n} } } > \frac{\r p - p }{\sqrt{\frac{p(1-p)}{n} } } )[/tex]

 The  z-score is  evaluated as

              [tex]z = \frac{\r p - p }{\sqrt{\frac{p(1-p)}{n} } }[/tex]

So  

         [tex]P(P > 0.75) = P(Z > \frac{0.75 - 0.60 }{0.05} )[/tex]

         [tex]P(P > 0.75) = P(Z > 3)[/tex]

         [tex]P(P > 0.75) = 0.0013499[/tex]

This value above is obtained from the z-table  

Answer:

A...............................

Answer:

5 years

Step-by-step explanation:

Principal Amount to be paid=$4500

Interest rate = 2%

Number if Times compounded= number of years

Number of years = x

Among total= $5010

A= p(1+r/n)^(nt)

But n= t =x

A= p(1+r/x)^(x²)

5010=4500(1+0.02/x)^(x²)

5010/4500 = (1+0.02/x)^(x²)

1.11333=( 1+0.02/x)^(x²)

Using trial and error method the number of years maximum to give approximately $5010 is 5 years

Answer: She can select 7 workshops if more than 4 must be about anthropology in 1716 ways.

Step-by-step explanation:

Given, The organizer of a conference is selecting workshops to include. She will select from 9 workshops about anthropology and 5 workshops about psychology.

If he select 7 workshops if more than 4 must be about anthropology, the possible combinations = (5 anthropology, 2 psychology), (  6 anthropology, 1 psychology), (7 anthropology, 0 psychology)

Number of possible combinations = [tex]^9C_5\times ^5C_2+^9C_6\times ^5C_1+^9C_7\times ^5C_0[/tex]

[tex]=\dfrac{9!}{5!4!}\times\dfrac{5!}{2!3!}+\dfrac{9!}{6!3!}\times(5)+\dfrac{9!}{7!2!}\times (1)\\\\=\dfrac{9\times8\times7\times6}{4\times3\times2\times1}\times\dfrac{5\times4}{2}+\dfrac{9\times8\times7}{3\times2\times1}\times5+\dfrac{9\times8}{2}\\\\=1260+420+36\\\\=1716[/tex]  [using formula for combinations [tex]^nC_r=\dfrac{n!}{r!(n-r)!}[/tex]]

Hence, she can select 7 workshops if more than 4 must be about anthropology in 1716 ways.

Answer:

D. (the last one)

Step-by-step explanation:

The horizontal row lists the 3 outcomes of the spinner.

The vertial column lists the 2 outcomes of the card selection.

In the resulting sample space of 2x3=6, each table cell should contain the combination of the row value and the column value.

So in the "Orange" column, all cells below it should start with Orange. Same for the other columns.

In the Purple row, each cell should end with Purple.

Only that way, each table cell represents a possible outcome.

Answer:

The  99%  confidence interval is

                     [tex]37.167< \= x < 44.833[/tex]

Step-by-step explanation:

From the question we are told that

  The sample size is  [tex]n = 29[/tex]

  The  sample mean is  [tex]\= x =[/tex]$41

  The  sample standard deviation is  [tex]\sigma =[/tex]$8

   The  level of confidence is [tex]C =[/tex]99%

Given that the confidence level id  99% the level of confidence is evaluated as

        [tex]\alpha = 100 - 99[/tex]

        [tex]\alpha = 1[/tex]%

Next we obtain the critical value of [tex]\frac{\alpha }{2}[/tex] from the normal distribution table which is  

      [tex]Z_{\frac{\alpha }{2} } = 2.58[/tex]

The reason we are obtaining values for  is because  is the area under the normal distribution curve for both the left and right tail where the 99% interval did not cover while   is the area under the normal distribution curve for just one tail and we need the  value for one tail in order to calculate the confidence interval

Next we evaluate the margin of error which is mathematically represented as

          [tex]MOE = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }[/tex]

substituting values

         [tex]MOE = 2.58 * \frac{8 }{\sqrt{29} }[/tex]

           [tex]MOE = 3.8328[/tex]

The 99% confidence level is constructed as follows

      [tex]\= x - MOE < \= x < \= x + MOE[/tex]

substituting values

    [tex]41 - 3.8328 < \= x < 41 + 3.8328[/tex]

     [tex]37.167< \= x < 44.833[/tex]

Answer:

There are 7 ways in which the formula can be evaluated to False.

Step-by-step explanation:

In order to solve this problem we will need to build a truth table. In order to build the truth table, we must start by setting the possible truth values combinations. In total there must be 8 rows, which you can see on the first three columns of the attached table.

Next, it is advisable that you divide the formula in little chunks of information that will be easier to evaluate. One column can be (p->q).

Let's evaluate that first column. In general, that column can only be false if p=T -> q=F. Which happens only on the 3dr and 4th rows of the table. The rest of the statements are true.

The next column will be (q->r). The same condition is met here, but this time you take into account the values given on the q and r columns. The false values will happen only on the 2nd and 6th rows. The rest of the rows for that collumn should be true.

Finally you can test for the whole formula. the first, 4th and 5th columns must be true for the formula to be true as well, which will happen only on the first row. The rest of the rows will have at least one false statement which makes the whole row false. So the rest of the rows are false.

Step-by-step explanation:

If the order is relevant, the number of permutations is:

₁₀P₅ = 30,240

If the order is not relevant, the number of combinations is:

₁₀C₅ = 252

The number of ways to choose 5 letters among 10 without replacement will be 252 and with replacements will be 30240.

When the order of the arrangements counts, a permutation is a numerical approach that establishes the total number of alternative arrangements in a collection.

The number of alternative configurations in a collection of things when the order of the selection is irrelevant is determined by combination.

The number of ways to choose r quantity among n without replacement is given as nCr = n!/(r!(n - 1)!)

n = 10 and r = 5

10C5 = 252

The number of ways to choose r quantity among n with replacement is given as, nPr = n!/(n - r)!

n = 40 and r = 5

10P5 = 10!/(10 - 5)! = 30240

Hence "The number of ways to choose 5 letters among 10 without replacement will be 252 and with replacements will be 30240".

Answer:

The first step would be to look at the average for each brand.

The average can be calculated as:

A = (a1 + a2 + .... + an)/N

where a1 is the first lifetime, a2 is the second one, etc. And N is the total number of data points.

So, for Brand 1 we have:

A1 = (260 + 218 + 184 + 219)/4 = 220.25

Brand 2:

A2 = (181 + 240 + 162 + 218)/4 = 200.25

Brand 3:

A3 = (238 + 257 + 241 + 213)/4 = 237.25

So only from this, we can see that Brand 3 has the larger lifetime, then comes Brand 1 and last comes Brand 2.
