D; The outlier

Answer:

D - outlier

Step-by-step explanation:

It can’t be A - the spread would the minimum and maximum.

‘Can’t be B - the mean in the overall average, which would probably be a bit higher than 13

Can’t be C - the median is the “middle” number when ordered smallest to largest. It would be 13 in this example

24 is an odd number compared to the rest. It seems like it might be an error in the data, because it is so different than all the rest - hence it is the outlier.

Answer:

3/4 Is equal to .74 and 2/3 is equal to 66.67

Step-by-step explanation:

Answer:

8/9

or

89% after being rounded to the nearest whole

Step-by-step explanation:

The connotation "of" means to divide to find the percent/part of the whole.

2/3 ÷ 3/4 = 2/3 x 4/3 = 8/9 = 0.88....

So it is either 8/9, or 89% (when rounded)

Answer:

  D.  All of the above

Step-by-step explanation:

Insurance costs are influenced by any factor that can reasonably be tied to the cost of claims made against an insurance policy. These costs are carefully analyzed by insurance companies to determine correlations that may be influential.

__

In general, women have different driving habits than men, so gender has an influence on insurance costs.

Some areas of a city have different statistics related to vandalized or stolen vehicles, so may influence insurance costs. Certain areas may have different accident statistics, or may experience different kinds of accidents, so repair costs may differ by where you live or where you drive.

Some cars are more expensive to repair than others. Any car with custom features (stereo, upholstery, paint) will likely cost more to repair (and may be subject to more vandalism).

So, all of the above influence insurance costs.

H0 : sample mean are equal

H1: sample mean are not equal

Using the Chisquare distribution calculator :

Chisquare :

(Observed - Expected)² ÷ Expected

Chisquare value = 1.759

Degree of freedom (df) = (row - 1) * (column - 1)

Df = (9-1) * (3-1) = 8*2 = 16 at α = 0.10

Pvalue = 0.999

Decision region :

Reject H0 if Pvalue < α

Since, 0.999 > 0.10 ; Then, Fail to reject H0

Hence, there is no difference in the mean price and the store means.

[tex]T_7 = 136.6875[/tex]

Step-by-step explanation:

Given

12, 18, 27, ..

Required

Determine the 7th term

The above sequence shows a geometric sequence and the nth term is calculated by:

[tex]T_n = a * r^{n-1[/tex]

r is calculated by:

[tex]r = \frac{T_2}{T_1}[/tex]

[tex]r = \frac{18}{12}[/tex]

[tex]r = 1.5[/tex]

[tex]a = 12[/tex] --- First term

[tex]n = 7[/tex]

So:

[tex]T_n = a * r^{n-1}[/tex]

[tex]T_7 = 12 * 1.5^{7-1[/tex]

[tex]T_7 = 12 * 1.5^6[/tex]

[tex]T_7 = 136.6875[/tex]

Answer:

Different playlists possible = 18287141644800

Step-by-step explanation:

Given - DJ Titus is making a playlist for a radio show; he is trying to

            decide what 10 songs to play and in what order they should be

            played.

            Step 1 of 2 : If he has his choices narrowed down to 7 blues,

                                 7 disco, 5 pop, and 7 reggae songs.

To find - He wants to play no more than 4 reggae songs.

              How many different playlists are possible ?

Proof -

Given that he wants to play no more that 4 reggae songs.

So the possibility of choice of reggae song is 0, 1, 2, 3, 4

Now,

Case I -

If 0 reggae song is selected

⇒All 10 songs selected from 7 blue, 7 disco, 5 pop,

Number of ways = ¹⁹C₁₀ ₓ ⁷C₀ = 92,378

Case II -

If 1 reggae song is selected

⇒All 9 songs selected from 7 blue, 7 disco, 5 pop,

Number of ways = ¹⁹C₉ ₓ ⁷C₁ = 646,646

Case III -

If 2 reggae song is selected

⇒All 8 songs selected from 7 blue, 7 disco, 5 pop,

Number of ways = ¹⁹C₈ ₓ ⁷C₂ = 1,587,222

Case IV -

If 3 reggae song is selected

⇒All 7 songs selected from 7 blue, 7 disco, 5 pop,

Number of ways = ¹⁹C₇ ₓ ⁷C₃ = 1,763,580

Case V -

If 4 reggae song is selected

⇒All 6 songs selected from 7 blue, 7 disco, 5 pop,

Number of ways = ¹⁹C₆ ₓ ⁷C₄ = 949,620

So,

Total possible ways = 92,378+ 646,646+ 1,587,222+ 1,763,580+ 949,620

                               = 5,039,446

⇒Total possible ways = 5,039,446

Now,

Also the 10 songs selected can arranged themselves in 10! ways. ( because order of song played does not matter )

∴ we get

Different playlists possible = 10! × 5,039,446

                                          = 18287141644800

⇒Different playlists possible = 18287141644800

Number of strawberry candy = [tex]\bold{8\ pieces}[/tex]

Number of rhubarb candy = [tex]\bold{7 \ pieces}[/tex]

Find the number of ways for equally distributing candy to all 5 children

Using formula:

[tex]\to \bold{_{n} C_{r}=\frac{n !}{r!(n-r) !}}[/tex]

Calculating the distributing way for strawberry candy:

[tex]\to \bold{_{8} C_{5}=\frac{8 !}{5!(8-5) !}}[/tex]

           [tex]\bold{=\frac{8 !}{5! \ 3 !}}\\\\\bold{=\frac{8 \times 7 \times 6 \times 5!}{5! \ 3 \times 2\times 1}}\\\\\bold{=\frac{8 \times 7 \times 6 }{ 6}}\\\\\bold{=8 \times 7}\\\\\bold{=56}[/tex]

Calculating the distributing way for rhubarb candy:

[tex]\to \bold{_{7} C_{5}=\frac{7 !}{5!(7-5) !}}[/tex]

           [tex]\bold{=\frac{7 !}{5! \ 2 !}}\\\\\bold{=\frac{7 \times 6 \times 5!}{5! \ 2\times 1}}\\\\\bold{=\frac{ 7 \times 6 }{ 2}}\\\\\bold{=7 \times 3}\\\\\bold{=21}[/tex]

Adding both distributing ways:
