In which the variables of the equation are listed as follows:

The sample is given as follows:

22, 40, 41, 42, 43, 48, 51, 58, 62, 66, 67, 70, 71.

The critical value, using a t-distribution calculator, for a two-tailed 95% confidence interval, with 13 - 1 = 12 df, is t = 2.1788.

Using a calculator with the sample, the parameters for the interval are:

[tex]\overline{x} = 52.38, s = 14.73, n = 13[/tex]

Hence the lower bound of the interval is calculated as follows:

52.38 - 2.1788 x 14.73/sqrt(13) = 43.479.

The upper bound of the interval is calculated as follows:

52.38 + 2.1788 x 14.73/sqrt(13) = 61.281.

The percentage increase for the money the class has raised is 10% and they will need $ 2115 to make the percentage increase to 99%.

According to the question,

We have the following information:

Initial price in the year = $1500

Final price they have = $1650

a) Now, we know that following formula is used to find the percentage increase in the price:

Percentage increase = 100*(final price-initial price)/initial price

Percentage increase = 100*(1650-1500)/1500

Percentage increase = 100*(150)/1500

Percentage increase = 10%

b) Now, we will find the final price when the percentage increase is 99%.

Let's take the final price to be $x.

99 = 100*(x-1500)/1500

99 = (x-1500)/15

Using the cross multiplication method:

x-1500 = 15*99

x-1500 = 615

x = 615+1500

x = 2115

Hence, the percentage increase for the money the class has raised is 10% and they will need $ 2115 to make the percentage increase to 99%.

Annie's new job pays more an hour.

Step-by-step explanation:

They tell us that her new job pays $7.25 per hour. So to determine which job pays her more, we need to find how much she earns in her current job.

There are a few ways to find this (none of them are hard.) But this is the easiest way in my opinion.

The chart tells you that Annie earns $13 in 2 hours. We need to find how much she earns in 1 hour. All you need to do is divide $13 by two.

13/2 = 6.5

6.5 = $6.50

If her current job pays her $6.50 an hour and her new job pays $7.25 an hour, she should consider higher paying jobs.

But, yes, the new job pays her more an hour.

Peanut brittle costs $0.33 more per ounce than the almond bark option (C) is correct.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

A candy company sells peanut brittle and almond bark.

Almond: $6/(10 oz) = $0.60/oz

Bark: $9/(10 oz) = $0.90/oz

0.90 - 0.60 = $0.90

Peanut brittle costs $0.33 more per ounce than almond bark.

The probability that both male and female are non-smokers is 0.56.

Given that, at a local college, 198 of the male students are smokers and 792 are non-smokers.

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favorable outcomes/Total number of outcomes

Number of male smokers=198

Number of male non-smokers=792

Total number of male smokers=198+792

= 990

Number of female smokers=330

Number of female non-smokers=770

Total number of female smokers=330+770

= 1100

Probability that both are non-smokers is given by

P(both are non-smokers ) = P(Male non-smoker) × P(female non-smoker)

= 792/990 × 770/1100

= 0.8 × 0.7

= 0.56

Therefore, the probability that both male and female are non-smokers is 0.56.

a. Matching with the country: 362,880, using the arrangements formula.

b. Not matching with the country: 60,949,324,800, using the permutation formula.

The number of possible arrangements of n elements is obtained by the factorial of n, that is:

[tex]A_n = n![/tex]

For item a, the arrangements formula is used, as the banner has to match the country, hence only the countries are arranged and then the specific banner is matched with this country.

Considering that there are nine countries, the number of ways of selecting and matching nine banners with a country is calculated as follows:

Total = 9! = 362,880.

The number of possible permutations of x elements from a set of n elements is obtained by the equation as follows:

[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]

For item b, 9 banners are taken from a set of 20, and the permutation formula is used as the order in which the banners are chosen is important, hence the number of ways of selecting nine banners without having to match them with a country is obtained as follows:
