The histogram for the stickers from the small package is distributed as follows:

Normally.

To obtain the distribution of the histogram, we must correctly identify the mean and the median of the distribution.

Hence the distribution is defined as follows:

The ordered distribution is given as follows:

13, 15, 18, 19, 22, 24.

Hence the median is of:

(18 + 19)/2 = 18.5.

The mean is of:

(13 + 15 + 18 + 19 + 22 + 24)/6 = 18.5.

They are equal, hence the histogram is normal = symmetric;

Answer: The monthly payment on a bank loan would be $480, which is lower than the monthly credit card payment.

To calculate the monthly payment on the bank loan, we can use the formula:

monthly payment = P * (r / (1 - (1 + r)^(-n)))

where P is the total loan amount, r is the annual interest rate as a decimal, and n is the number of months of the loan.

For a loan of $16,000 at 8% interest for 3 years (36 months)

r = 0.08/12 = 0.0067

n = 36

P = 16000

So, the monthly payment = 16000 * (0.0067 / (1 - (1 + 0.0067)^(-36))) = 480

To calculate the monthly credit card payment, we can use the formula:

M = P * r * (1 + r)^n / [(1 + r)^n - 1]

where P is the total loan amount, r is the monthly interest rate, and n is the number of months of the loan.

For a credit card with an annual rate of 15% for 7 years (84 months)

r = 0.15/12 = 0.0125

n = 84

P = 16000

So, the monthly payment = 16000 * 0.0125 * (1 + 0.0125)^84 / [(1 + 0.0125)^84 - 1] = 511.11

As we can see the monthly payment on the bank loan is lower than the monthly credit card payment. So, the correct answer is "The monthly payment on a bank loan would be $480, which is lower than the monthly credit card payment."

As a set of inputs with one output for each, a function is defined as a relationship between them.

An expression, rule, or law in mathematics that specifies the relationship between an independent variable and a dependent variable (the dependent variable).

A relationship between a group of inputs and one output each is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function.

When examining a graph, one method is to perform a "vertical line test" to see if a relationship is indeed a function. Anywhere on the graph where a vertical line can be created to cross the relation twice indicates that the relationship is not a function.

The ratio of people in its simplest form is 1 : 3

The ratio of benches in its simplest form is 1 : 4

A ratio is the number representing a comparison between two named things.

It also refers to the relative magnitudes of two quantities usually expressed as a quotient.

For instance, if there are 12 students in a class which includes 8 girls and 4 boys,

The ratio of girls to all students = 8 : 12

= 8/12

= 2/3

= 2 : 3

The ratio of boys to girls = 4 : 8

= 4/8

= 1/2

= 1 : 2

The ratio of all students to boys = 12 : 4

= 12/4

= 3/1

= 3 : 1

Hence,

People = 6 : 18

= 6 / 18

= 3 / 9

= 1/3

= 1 : 3

Benches = 3 : 12

= 3 / 12

The completed statement would be

12ft/sec = 7.2 yd/min.

What is the unit conversion?

Unit conversion is the process of changing a measurement from one unit to another, while maintaining the same numerical value. It is used to convert measurements from one system of units to another, such as from metric units to imperial units, or from feet to meters.

To convert feet per second to yards per minute, we need to multiply the value in feet per second by the conversion factor of 1 yard/3 feet and then divide the result by the conversion factor of 1 minute/60 seconds.

12 ft/sec = (12 ft/sec) * (1 yard/3 feet) * (1 min/60 sec) = (12*1/3) * (1/60) = 4/5 = 0.8.

So, 12 ft/sec is equal to 0.8 yards per minute. Rounded to the nearest hundredth, this is 7.2 yards per minute

The evaluation of the arithmetic series  gives 4545

An arithmetic progression ( AP ) is a sequence of numbers such that the difference between the consecutive terms is constant.

From the given information, we can get the first term (a) and  last term (l) of the sequence by substituting n = 1  and n = 45 respectively into the given expression, (4n + 9). That is:

a = 4(1) + 9 = 13

l = 4(45) + 9 = 189

Sum of all terms in a finite AP with the first term (a) and last term (l) is given by:

S = n/2(a + l)

S = 45/2 (13+189) = 4545

Thus, the arithmetic series evaluates to
