The cubic feet of air the scuba diver used per minute is 1.2 cubic feet of air per minute

Cubic feet of air used per minute = Difference in quantity of air in his tank / difference in time

= (30 - 12) / (3:30pm - 3:15pm)

= 18 / 15

= 1.2 cubic feet of air per minute

Therefore, the cubic feet of air the scuba diver used per minute is 1.2 cubic feet of air per minute

The range is the difference between the highest and lowest values within a set of numbers. To calculate range, subtract the smallest number from the largest number in the set.The statistical distributions' characteristics are described by the terms mean, median, mode, and range. The set of all potential values for terms that indicate predetermined events is known as a distribution in statistics. A term's value stated as a variable is referred to as a random variable.

The two main categories of statistical distributions are as follows. There are discrete random variables in the first category. This indicates that each phrase has a distinct, precise numerical value. A continuous random variable is present in the distribution of the second major kind. An unlimited number the  of possible values can be represented by a continuous random variable.

The frequency distribution for the given data is:

Treating the frequency distribution as a discrete distribution, we have that:

The pie chart is missing, but is given at the end of the answer.

A relative frequency is given by the number of desired outcomes divided by the number of total outcomes.

A frequency distribution is composed by the relative frequencies of each outcome. From the pie chart, we have that there is a total of 3 + 13 + 22 + 17 + 14 + 13 + 4 = 86 people, hence the frequency distribution is given as follows:

This is relevant because we want to treat the frequency distribution as a discrete distribution, taking the midpoint of each interval, hence:

Hence the mean is:

E(X) = 0.0349 x 2 + 0.1512 x 7 + 0.2558 x 12 + 0.1977 x 17 + 0.1628 x 22 + 0.1512 x 27 + 0.0465 x 32 = 16.71.

The mean is of 16.71.

The standard deviation is found as follows:

S(X) = sqrt[0.0349 x (2 - 16.71)² + 0.1512 x (7 - 16.71)² + 0.2558 x (12 - 16.71)² + 0.1977 x (17 - 16.71)² + 0.1628 x (22 - 16.71)² + 0.1512 x (27 - 16.71)² + 0.0465 x (32 - 16.71)²] = 10.95.

The standard deviation is of 10.95.

If the side-lengths of a triangle are increased by a scale factor of 4 then the area will be 16 times greater.

As given in the question,

Let 'a' be the base of the triangle

and 'h' be the height of the triangle

Area of the triangle = (1/2)×a× h

Side length increased by scale factor 4

New base = 4a

New height=4h

New area=(1/2)×4a×4h

              = 16×(1/2)×a ×h

              = 16 times the original area

Therefore, if the side-lengths of a triangle are increased by a scale factor of 4 then the area will be 16 times greater.

Step-by-step explanation:

maybe you missed something in the problem definition or in the answer options, but the answer options do not contain any right answer to the described problem.

20 - sqrt(80) = 20 - sqrt(16×5) = 20 - 4×sqrt(5) =

= 11.05572809...

it is simple to estimate, in what dimension the result should be : 80 is very close to 81. so the sqrt(80) is also very close to the sqrt(81), which is 9.

20 - 9 = 11.

so, all the negative answer options are wrong by default.

and the only positive one is 2×sqrt(5) = 4.472135955...

additional thoughts :

20 = 4×5 or 4×sqrt(5)×sqrt(5)

so, we could write the problem as

4×sqrt(5)×sqrt(5) - 4×sqrt(5)

which could be simplified to either

4×sqrt(5)×(sqrt(5) - 1)

or

4×(5 - sqrt(5))

The customer would pay $54.40 for the shoes

What is the dollar value of the initial discount of 20%?

The dollar worth of the general discount of 20% of the price of $80 is determined as 20% multiplied by the shoe price

dollar worth of initial discount=20%*$80

dollar worth of the initial discount=$16

the price after the initial discount=$80-$16

the price after the initial discount=$64

The fact the customer has a coupon to receive additional 15% off the sale price means the purchase price for the customer is as computed thus:

final sale price=$64*(1-15%)

If an Apple Computer store sells computers for $1,234.88 and the computers cost $10,896 per dozen, then the dollar markup for each computer is $326.88 and the percentage markup is 36%

Given,

An Apple Computer store sells computers = $1234.88

The cost of computers per dozen = $10896

Cost of one computer = [tex]\frac{10896}{12}[/tex] = $908

Then the dollar markup for each computer = 1234.88-908

=$326.88

Percentage markup = [tex]\frac{326.88}{908}[/tex]×100

=36%

The formula that describes the sequence given i.e. [tex]\frac{-2}{3}[/tex],-4,-24,-144 (geometric sequence) is [tex](\frac{-2}{3} )(6)^{n-1}[/tex]

Geometric progression:

A geometric progression or a geometric sequence is a series, in which each word is varied by another by a common ratio. When we multiply the previous term by a constant (which is non-zero), we get the following term in the sequence. It is symbolized by:

A, AR,[tex]AR^{2}[/tex],[tex]AR^{3}[/tex]...

Where A is the first term of the geometric sequence and R is the common ratio of the geometric sequence.

The general term of geometric sequence i.e. nth term =[tex]AR^{n-1}[/tex]

Given that A= [tex]\frac{-2}{3}[/tex] and R=6

As a result the general term of geometric sequence i.e. nth term =[tex](\frac{-2}{3} )(6)^{n-1}[/tex]

[tex]A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}[/tex]

In which:

For this problem, the parameters are given as follows:

The minimum price, discounting the down payment, is found when A = 2400, hence:

[tex]A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}[/tex]

[tex]2400 = 0.00375P\frac{(1.00375)^{360}}{(1.00375)^{360} - 1}[/tex]

[tex]P = \frac{2400[(1.00375)^{360} - 1]}{0.00375 \times (1.00375)^{360}}[/tex]

P = $473,666.78.

Considering the down payment, we add $40,000, hence the minimum value of the range is: $513,666.78.

The maximum price, discounting the down payment, is found when A = 3000, hence:

[tex]A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}[/tex]

[tex]3000 = 0.00375P\frac{(1.00375)^{360}}{(1.00375)^{360} - 1}[/tex]

[tex]P = \frac{3000[(1.00375)^{360} - 1]}{0.00375 \times (1.00375)^{360}}[/tex]

P = $592,083.48.

Considering the down payment, we add $40,000, hence the maximum value of the range is: $592,083.48.

Hope this helps :)Explanation and Check part below.

Step-by-step explanation:

1. Get the variable on one side by subtracting x.

x - 6 = 1/3x + 4

- 1 x - 1 x

- 6 = - 2/3x + 4

2. Subtract 4 which is the inverse operation of addition.

- 6 = - 2/3x + 4

- 4 - 4

- 10 = - 2/3x

3. Divide by - 2/3 which is the invers eoperation of multiplication.

- 10 = - 2/3x

- 2/3 - 2/3

(Keep,Change,Change - KCC method)

- 10 ÷ - 2/3 = - 10 × - 3/2 = 30/2 = 15

- 10 = - 2/3x

- 2/3 - 2/3

15 = x → x = 15
