How many games for 10 teams to play each other twice?.

The correct option is (a) Gareth will choose the Brand R credit card for the freezer because it is $548.18 less expensive than the Brand S.

An annual percentage rate, or APR, is used to express the interest rate that is applied to the principal amount of a loan.

The credit card's yearly percentage rate is 9.31%.

Gareth takes four years to pay off a Brand R freezer compared to just 18 months for a Brand S freezer.

Overall, ten years have gone.

To determine which credit card has the lowest lifetime cost for a freezer, we must compare the APRs of the two cards.

Let's say there are 1000 freezers. As a result, the APR for 18 months will be lower because the interest rate's duration is shorter.

The B and R will therefore be $548.18 less expensive than Brand S, according to a comparison of the APR.

Answer:

C. 20

Step-by-step explanation:

Since 11 times 4 = 44, you can multiply your 5 by 4 to get 20.

3,14,19,25,14 is set of data has a mean of 15 a range of 22 a median of 14 and a mode of 14.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

First, arrange the given set in ascending order.

3,14,19,25,14

Ascending order = 3, 14, 14, 19, 25

Mean = sum of observations/total observations

(3+14+14+19+25)/5

75/5

15

Median is the middle number of the data.

3, 14, 14, 19, 25

14 is the median

The Mode is the number that occurs most number of times.

3, 14, 14, 19, 25

In the given data, 14 occurs two times. so, 14 is the mode.

Range:

Range is highest value - lowest value

3, 14, 14, 19, 25

=> 25 - 3 =22

so, range is 22.

Hence, the required set of data is 3,14,19,25,14

After solving, the height of the building is 15.19 m tall.

In the given question, a baseball dropped from the roof of a tall building takes 3. 1 seconds to hit the ground.

We have to find the height of the building.

Initial Velocity, denoted as u, is the velocity at time interval t = 0. It is the speed at which motion first occurs.

Initial velocity u=0

Time t=3.1 seconds

Let height of the cliff is h.

So s=ut+at^2/2

Now putting the value

The price level that people expected rise above.

What is the term for price increases?

The rate at which prices rise over a given time is called inflation. A country's cost of living or overall increase in prices are two examples of broad measures of inflation.

What happens when the price level rises above expectations?

The economy's leading indicators are price levels; Inflation occurs when prices rise in response to increased demand, while deflation occurs when prices fall in response to decreased demand.

What happens when the price rises?

The average price of all goods and services sold rises when an economy's price level rises. The percentage increase in a nation's price level over some time, typically a year, is what is used to calculate inflation. This indicates that inflation is taking place during the time when prices rise.

Using the Equivalent Taxable yield formula ,

the equivalent Taxable yield for a taxpayer is 10.75%.

Equivalent Taxable yield :

Tax-equivalent yield is determined by taking the yield of a tax-exempt bond and dividing it by one minus an investor's federal income tax bracket.

Tax-equivalent yield is a way to measure the return on a taxable bond or other investment to make it equal to the return associated with a tax-exempt bond or investment.

Formula:

Tax-equivalent yield = interest rate ÷ (1 – tax rate)

We have given that

Marginal tax bracket or tax rate = 33%

currently priced yield = 7.2 %

Equivalent taxable yield = Yield / ( 1 - Tax% )

= 7.2% / ( 1 - 33% )

Step-by-step explanation:

Find the unit costs

[tex]\frac{4.80}{12}[/tex] = .4

[tex]\frac{10.40}{26}[/tex] = .4

The area of square abcd is  be parallel lines passing through $a$, $b$, $c$, respectively is the 433.

Squares are quadrilaterals with four congruent aspects and four proper angles, and additionally they have units of parallel aspects. Parallelograms are quadrilaterals with units of parallel aspects. Since squares have to be quadrilaterals with units of parallel aspects, then all squares are parallelograms.

Here we have the values the distance between lines a and b is 12, and the distance between lines b and c is 17.

The distance is 12 and 17

Higher mean absolute deviation is an example of a measure of variability and range. It give us some information about how spread out the data in a data set is. When used together with measures of center like the mean and median, they can give us a useful overview of the data set.

For an example,

A chef wants to hire someone to work in his kitchen. There are two candidates: Sally and Nader. To test their abilities, he times how long it takes them to make each of four meals and records the data in two tables.

He decides to calculate the mean time it took each candidate to make the four meals; he is planning to hire the candidate with the lower (quicker) mean time.

The mean time it takes Sally to make a meal is

= 3+5+7+9 / 4

=24/6

= 6 minutes

The mean time it takes Nader to make a meal is

= 5+6+5+8 / 4

=24/4

= 6 minutes

After having mean times same he doesn't classify which one is best he used their statical graphs.

For Sally, the mean absolute deviation of her times is the mean of the distances,

=4+1+2+3 / 4

=2.5

For Nader, the mean absolute deviation of his times is

= 1+0+1+2 / 4

=1

The chef sees that the mean absolute deviation of Nader’s times is lower than the mean absolute deviation of Sally’s times. This shows that Nader is more consistent in his cooking times and agrees with what we observed from the bar graphs.

Which means that the higher mean absolute deviation occurs less consistency in the mean absolute deviation.

Ciphers, such as the enigma machine, that rearrange the sequence of characters based on a fixed rule are known as substitution cipher.

A type of encryption known as a replacement cypher employs a key to substitute certain plaintext chunks with the ciphertext in a predetermined manner.

Single letters, pairs of letters, triplets of letters, combinations of the aforementioned, etc. are all acceptable "units." The receiver decodes the text using the inverse substitution technique to ascertain what the original message was.

Cyphers for transposition and substitution are similar. In a transposition cypher, the plaintext's units are not changed; instead, they are rearranged in a brand-new, frequently extremely complex pattern. A substitution cypher modifies the units themselves while preserving the order of the units from the plaintext in the ciphertext.

The substitution cypher can take many different shapes. If a cypher only functions with single letters, it is referred to as a simple substitution cypher; a polytrophic cypher, on the other hand, functions with larger groups of letters.

Using the Real rate of return,

the real value of the invetment at the end of one year is $1058.

Real rate of return:

The real rate of return is the present value of the return on investment after taxes and inflation.

By considering the expected inflation rate and the effective interest rate in the compounding interval, we can derive the real interest rate.

Real Rate Of Return Formula,

Real rate of return = [( 1+ Nominal rate )/(1+ inflation rate) ] - 1

The principal amount of investment by Mr.X ( A)

= $1,000

The nominal or current rate of interest (i)= 10%

The rate of inflation ( π )= 4%

pulging all the values in above formula we get,

rate of return (R) =[ ( 1 + i ) /(1+π)] - 1

=> R =[ (1+0.1 )/(1+0.04) ] - 1 = (1.1 / 1.04 ) - 1

=> R = 0.05769(approx.)

=5.8%(approx.)

so, real rate of return = 5.8%

Real value of investment after a year = principle amount (A) + { real rate return × principle amount}

Real value of investment =$1,000+{5.8%×$1,000}

=$1,000+$58

=$1,058

Hence, real value of investment at the end of year is $1,058.

With including a new race time of 24.9s the mean will change from 21.9s to 22.5s by 0.6s

What is mean?

The mean is the average or the most common value in a collection of numbers.

In statistics, it is a measure of central tendency of a probability distribution along median and mode.

It is also referred to as an expected value.

According to the given question:

His initial mean would be calculated by:

His minimum race time = 18.9s

The maximum race time = 18.9 + 5.2 = 24.1s

Since the mode is also 24.1, there are two 24.1s races.

Since the median is 22.3s and the number of race times is even, the final race time can be calculated by:

24.1 - 22.3s = 1.8s

22.3 - 1.8 = 20.5s

So the race times are 18.9s, 20.5s, 24.1s and 24.1s.

This means that his initial mean was ( 18.9 + 20.5s + 24.1 + 24.1)/4 = (87.6)/4 = 21.9s

With the new race time, the equation will change to (87.6 + 24.9)/(4+1)= 112.5/5= 22.5s

So the mean change would be 22.5 - 21.9 = 0.6 s
