The amount of money in the account after 2 years is $573.04.

What is compound interest?

Compound interest is the interest earned on an initial principal deposit as well as on the accumulated interest from previous periods. In other words, it is interest on interest.

To calculate the amount of money in the account after 2 years, we can use the formula for compound interest:

A = P(1 + r/n)ⁿᵗ

where A is the final amount, P is the principal amount (the initial deposit), r is the annual interest rate (as a decimal), n is the number of times the interest is compounded per year, and t is the time period (in years).

In this case, P = $500, r = 0.07 (7%), n = 1 (compounded annually), and t = 2.

Plugging these values into the formula, we get:

A = 500(1 + 0.07/1[tex])^{(1 \times 2)}[/tex]

A = 500(1.07)²

A = $573.04

Therefore, the amount of money in the account after 2 years is $573.04.

The line plot is attached based on the information given.

A line plot is a graph that shows data as dots or checkmarks above a number line to indicate how frequently each value occurs. Only numerical, discrete data, not continuous data, is shown using line graphs. Line plots categorize the data by showing how often each value appears on a number line. Small data sets make these graphs easy to make, and the revealed frequency patterns allow for interpretation.

Each mark on the line plot represents one of the distances Tomas rode. The number on the horizontal axis represents the day of the week and the vertical axis represents the distance in miles. The line plot shows that on most days, Tomas rode between 3 and 5 1/2 miles.

Step-by-step explanation:

since you know already that you need the law of cosine (which is nothing else than the generalization of Pythagoras from right-angled triangles to general triangles), why don't you just apply it ?

the law of cosine :

c² = a² + b² - 2ab×cos(C)

c is the side opposite of angle C, a and b are the other 2 sides.

our angle C is here now the angle QPR. the opposite side is QR = 3.

so, we have

3² = 2² + 4² - 2×2×4×cos(QPR) = 4 + 16 - 16×cos(QPR)

9 = 20 - 16×cos(QPR)

-11 = -16×cos(QPR)

cos(QPR) = -11/-16 = 11/16 = 0.6875

FYI : that means

angle QPR = 46.56746344...°

well, if a value goes from 88 to 20, it clearly decreased, hmmm 88 - 20 = 68, by 68 units.

so if we take 88(origin amount) to be the 100%, what's 68 off of it in percentage?

[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} 88 & 100\\ 68& x \end{array} \implies \cfrac{88}{68}~~=~~\cfrac{100}{x} \\\\\\ \cfrac{ 22 }{ 17 } ~~=~~ \cfrac{ 100 }{ x }\implies 22x=1700\implies x=\cfrac{1700}{22}\implies x\approx 77.3[/tex]

The height of the building is approximately 79.22 meters, rounded to the nearest meter.

To calculate the angle of elevation, we use the tangent function, which is defined as the ratio of the opposite side to the adjacent side of a right triangle.

We know that the pole is 3.5 meters tall, and its shadow is 1.77 meters long. We can use this information to calculate the angle of elevation of the sun's rays, which is the angle formed between the horizontal line and the line of sight from the top of the pole to the sun.

In this case, the opposite side is the height of the pole (3.5 meters), and the adjacent side is the length of the shadow (1.77 meters). Therefore, we have:

tan(angle of elevation) = opposite/adjacent = 3.5/1.77

Using a calculator, we can find that the angle of elevation is approximately 63.24 degrees.

Now, we can use this angle to find out the height of the building. We know that the shadow of the building is 43.5 meters long, and we want to find its height, which is the opposite side of the right triangle formed by the angle of elevation and the length of the shadow. Therefore, we have:

tan(63.24 degrees) = opposite/43.5

Solving for the opposite, we get:

opposite = 43.5 * tan(63.24 degrees) = 79.22 meters

A t-test is a statistical test used to determine if there is a significant difference between the means of two groups.

In this case, the two groups being compared are first basemen and all other players, and the variable being measured is salary. By performing a t-test, we can determine if there is a significant difference in the average salary between first basemen and all other players.

To perform a t-test, we first calculate the difference in means between the two groups and divide by the standard error of the difference. The standard error takes into account the variability in the sample and the sample size. The result is the t-statistic, which is then compared to a t-distribution with degrees of freedom equal to the sum of the degrees of freedom of the two groups minus 2. The t-distribution gives us the probability of observing a difference as large or larger than the observed difference by chance if the two groups have the same mean. This probability is known as the p-value.

Step-by-step explanation:

The cumulative relative frequency distribution is a useful tool for summarizing data and making comparisons between classes. It can also be used to make predictions about future data values.

A cumulative relative frequency distribution is a table that shows the cumulative relative frequency of a set of data. A cumulative relative frequency is the sum of all relative frequencies up to a certain point in the data set. For example, if the first three entries in a data set are 20, 30, and 10, the cumulative relative frequency of the first entry would be 0.2, the cumulative relative frequency of the second entry would be 0.5, and the cumulative relative frequency of the third entry would be 1.0.

In a cumulative relative frequency distribution, the data is organized into classes, and each class has a relative frequency associated with it. The relative frequency is the fraction of the total number of items in the class compared to the total number of items in the data set. The cumulative relative frequency is the sum of the relative frequencies of all the classes up to that point.

For example, if there are five classes in a data set, the cumulative relative frequency of the first class would be the relative frequency of the first class. The cumulative relative frequency of the second class would be the sum of the relative frequencies of the first and second classes, and so on.

The function g(x) = 5x²models the number of bulbs she will plant is  if the garden has a side length of 8 feet, Cindy will plant 320 tulip bulbs.

What is Function?

A function is a mathematical rule that assigns a unique output value for every input value. In other words, a function is a relation between a set of inputs and a set of possible outputs with the property that each input is related to exactly one output.

Functions are often denoted using function notation, such as f(x), where "f" is the name of the function and "x" is the input. The output of the function is denoted by f(x), which is read as "f of x" and represents the value of the function at the input value x.

To find the number of bulbs Cindy will plant if the garden has a side length of 8 feet, we need to evaluate the function g(8) = 5(8)²

Using the order of operations, we first need to square the side length, which gives us 8² = 64.

Then, we multiply 64 by 5 to get the total number of bulbs:

g(8) = 5(64) = 320

Therefore, if the garden has a side length of 8 feet, Cindy will plant 320 tulip bulbs.

Answer: Let's assume the exchange rate between ZAR and EUR is given by E1, and the exchange rate between ZAR and CAD is given by E2.

First, let's calculate the cost of the CD in ZAR:

5 EUR * E1 = 5 * E1 ZAR

Next, let's calculate how much money Teboho will have left after purchasing the CD:

250 ZAR - 5 * E1 ZAR = 245 ZAR - 5 * E1 ZAR

Now, let's calculate the cost of the CD in CAD:

7 CAD * E2 = 7 * E2 ZAR

We need to determine the value of E1 and E2 in order to compare the prices. However, without knowing the current exchange rates, we cannot determine the best option for Teboho. If the exchange rate between ZAR and EUR is favorable and the cost of the CD in ZAR is lower than the cost of the CD in CAD, Teboho should order the CD from Germany. On the other hand, if the exchange rate between ZAR and CAD is favorable and the cost of the CD in CAD is lower than the cost of the CD in EUR, Teboho should order the CD from Canada.

The linear equation of the line which passes through the points (-2, -3) and (2, -1) is:

   y + 3 = 0.5 (x + 2)

What is meant by a linear equation?

An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation. A linear equation is a straight line equation.

It is of the form: y = mx + c

where m = slope of the line

c = x-intercept of line.

The linear equation of a line is:

y - y₁ = m ( x - x₁)

Given two points on the line

(x₁ , y₁) = (-2, -3)

(x₂ , y₂) = (2, -1)

m = slope of line =  (y₂ - y₁) / (x₂ - x₁) = (-1 - (-3)) / (2 - (-2)) = 2/4 = 1/2

Now substituting this value in the general equation, we can write the equation as:

y - (-3) = 1/2 ( x -(-2))

y + 3 = 0.5 (x + 2)

Therefore the linear equation of the line which passes through the points (-2, -3) and (2, -1) is:

   y + 3 = 0.5 (x + 2)

One box of dog food costs $7, while one can of cat food costs $8.

Equations are statements in mathematics that have two algebraic expressions on either side of the equals (=) sign.

It illustrates that the expressions printed on the left and right sides have an equal relationship.

Some of the components of an equation are coefficients, variables, operators, constants, terms, expressions, and the equal to sign. When expressing an equation, the "=" symbol and terms on both sides are a need.

Given data ,

Let the price of a single box of dog food at  x.

Let's say the price of one can of cat food is y.

The cost of 1 box of dog food and 2 cans of cat food is  = $ 23

One can of cat food and two boxes of dog food cost $22, total.

So , the equation will be

1x + 2y = 23                                 ....... (1)

2x + 1y = 22                                  ....... (2)

Equation (1) is multiplied by 2 to get

2x + 4y = 46                                ....... (3)

When equation (2) is subtracted from equation (3), we obtain

3y = 24

value of y is obtained by dividing both sides by 3,

y = $ 8

Equation (1) can be solved by substituting the value of y.

x + [tex]2*8[/tex] = 23

x + 16 = 23

16 is subtracted from both sides, giving us

x = $ 7

Therefore , the value of x is $ 7 and value of y is $ 8
