At a simple annual interest rate of 3%, the following formula might be used to determine the annual interest for a $4200 principal:

Interest is calculated as follows: Principal * Rate * Time

Where,

Capital = $4200

Rate = 3% (expressed as a decimal by dividing by 100) (expressed as a decimal by dividing by 100)

t = one year

When we enter the values, we obtain:

Interest is equal to $4200 multiplied by 0.03 times one.

Therefore, $126 would be the annual interest for a $4200 principal at a basic annual interest rate of 3%.

The sequence types are (a) arithmetic seqience and (b) geometric seqience

Given that the annual rase ie $3500

This is an arithmetic seqience

And it means that there will be an addition of $3500 in the salary each year

So, we have

Common difference = 3500

b) an annual raise of 5% of his current salary.

Given that the annual rase is 5% of the current salary

This is a geometric seqience

And it means that the raise would be 5% of previous salary

Plotting the relationship between the number of hours studied and exam results reveals a negative correlation curve, where the exam results get worse as the number of hours studied rises.

The point (10,70) would be plotted on the negative correlation curve, for instance, if a student spent 10 hours studying and received a 70 on their exam. A downward sloping negative correlation curve would result as study time increased and exam score decreased. A graph illustrating the relationship between two variables, where an increase in one variable is accompanied by a drop in the other, is called a negative correlation curve. Numerous various types of situations, such as the amount of hours studied and exam results, might demonstrate this type of link. Exam scores typically decline as the amount of study time increases.

The minimum number of rides Scott has to go on is 7 or more rides.

What is inequality ?

An inequality is a mathematical statement that compares two quantities, expressing that one is greater than, less than, or equal to the other. Inequalities are often represented using inequality symbols such as < (less than), > (greater than), ≤ (less than or equal to), or ≥ (greater than or equal to).

According to the question:

Let's start by finding an expression for the total cost of each amusement park in terms of the number of rides, x. For Amusement Park A, the total cost is:

Total cost for Amusement Park A = 40 + 2.5x

This is because there is a $40 entry fee plus $2.50 for each ride.

For Amusement Park B, the total cost is:

Total cost for Amusement Park B = 30 + 4x

This is because there is a $30 entry fee plus $4.00 for each ride.

To find the minimum number of rides Scott has to go on so that the total charge at amusement park A costs less than the total charge at amusement park B, we can set up an inequality comparing the total cost of the two amusement parks:

40 + 2.5x < 30 + 4x

This inequality is saying that the total cost for Amusement Park A is less than the total cost for Amusement Park B. We want to solve for x, which represents the minimum number of rides that Scott has to go on to make Amusement Park A cheaper than Amusement Park B.

To solve for x, we can simplify the inequality:

40 + 2.5x < 30 + 4x

10 < 1.5x

6.67 < x

So the minimum number of rides Scott has to go on to make Amusement Park A cheaper than Amusement Park B is 7 (rounded up from 6.67). Therefore, if Scott goes on 7 or more rides, Amusement Park A will be cheaper than Amusement Park B.

Answer:

Uncle Mike was 7 times as old as Sally 17 years ago.

Step-by-step explanation:

Let's call Uncle Mike's current age "x."

Sally is 12 years old, so x = 12 * 3 = 36 years old.

We are looking for years that must pass before Uncle Mike is only twice as old as Sally. So we need to find the age when x = 2 * (12 + n), where n is the number of years that have passed. Solving for n:

36 = 2 * (12 + n)

36 = 24 + 2n

12 = 2n

n = 6

So, six years must pass before Uncle Mike is only twice as old as Sally.

To find out how many years ago Uncle Mike was 7 times as old as Sally, we need to find the age when x = 7 * (12 - m), where m is the number of years ago. Solving for m:

36 = 7 * (12 - m)

36 = 84 - 7m

120 = 7m

m = 17

So, Uncle Mike was seven times as old as Sally 17 years ago.

what is fraction ?

A fraction is a mathematical representation of a part of a whole or a ratio between two quantities. It is typically represented as a top number (numerator) divided by a bottom number (denominator), separated by a horizontal line.

For example, the fraction 3/4 represents three parts out of four equal parts of a whole. The numerator (3) represents the number of parts, while the denominator (4) represents the total number of parts that make up the whole.

According to the question:
To compare 2.2 and 14/4, we can convert 14/4 to a decimal:

14/4 = 3.5

Now we can see that 2.2 is less than 3.5. Therefore, we can say that:

2.2 < 14/4

Another way to compare them is to convert both numbers to a common denominator. In this case, the common denominator of 2.2 and 14/4 is 10:

2.2 = 22/10

14/4 = 35/10

Now we can see that:

22/10 < 35/10

Therefore, we can conclude that 2.2 is less than 14/4.

To check the validity of the EAN-13 barcode, we need to perform a computation based on the numbers in the code. The EAN-13 code consists of 13 digits, where the first digit represents the number system, the next five digits represent the manufacturer code, the following five digits represent the product code, and the last digit is the check digit.

The check digit is calculated based on the previous 12 digits using a specific algorithm.

For the given EAN-13 code 4-800016-653094, we can extract the previous 12 digits as 480001665309. To calculate the check digit, we need to multiply the first, third, fifth, etc. digits by 3, and the second, fourth, sixth, etc. digits by 1, and then sum these products. In this case, the calculation is as follows:

(4x3) + 8 + (0x3) + 0 + (0x3) + 1 + (6x3) + 6 + (5x3) + 3 + (0x3) + 9 = 74

The check digit is then the smallest number that, when added to the sum above, results in a multiple of 10. In this case, the check digit is 6, since 74 + 6 = 80, which is a multiple of 10.

Step-by-step explanation:

The most appropriate measure of center is median.

option B.

The choice of measure of center (i.e., the most appropriate way to summarize the "typical" value of a dataset) depends on the distribution of the data and the research question being addressed. In general, the most commonly used measures of center are the mean and the median.

The mean is the arithmetic average of a dataset, and is often used as the measure of center for datasets that follow a normal or symmetrical distribution, where the data are roughly evenly distributed around a central value.

The median, on the other hand, is the middle value of a dataset when the values are arranged in order from smallest to largest.

For the given data, it is not evenly distributed but it is arranged from the smallest to the largest, so we can use median as the most appropriate measure of center.

The perimeter of the original parallelogram is 22/9 * √3

The vertices of the parallelogram are A, B, C, and D, with AB parallel to CD and AD parallel to BC.

The parallel lines intersect the sides of the parallelogram at E, F, G, and H.

The side length of the equilateral triangle is s.

The three regions have the same area, hence, the area of each region is 1/3 of the total area of the parallelogram.

Let's the area of the parallelogram as A.

The area of the equilateral triangle is (s²√3)/4

This area is one-third of A

(s²√3)/4 = A/3

s² = 4A/(3√3)

Considering the whole parallelogram;

AB is parallel to CD, hence, triangle AEF is similar to triangle BGF

Also, AD is parallel to BC, hence, triangle ADE is similar to triangle BCF.

AE/EB = BF/FG AD/DE

AE/EB = BC/CF

Expressing AE, BF, AD, and BC in terms of s:

AE = s/3 (perimeter of the equilateral triangle is 1)

EB = 2s/3

BF = 2s/3

FG = s/3

AD = (2s + 2EB)/3

AD = (2s + 4s/3)/3

AD = 10s/9

DE = (2s + 2AE)/3

DE = (2s + 2s/3)/3

DE = 8s/9

BC = (2s + 2FG)/3

BC = (2s + s/3)/3

BC = 7s/9

CF = (2s + 2BF)/3

CF = (2s + 4s/3)/3

CF = 10s/9

Now we can find the perimeter of the parallelogram:

Perimeter = 2(AB + AD)

Perimeter = 2(EB + BC)

Perimeter = 2(2s/3 + 7s/9)

Perimeter = 4s/3 + 14s/9

Perimeter = (22s/9)
