We should know that value is the amount left in an account at a particular time

The  given parameters are

In 1990 the value is = $4,800.

In 1998,  the value is =$6,300

From 1990 to 1998 there are 8 years

Increase in the investment

Using simple interest,

SI= (P*T*R)÷100

Applying the figures in the formula

1500=(4800*8*R)÷100

⇒ 15000=30400R

Making R the subject we have

R= 4.93%

This ratio is used to compare the variances of the two samples and determine if they are statistically equal.

The test for the equality of two population variances is a statistical test used to determine whether or not the variances of two populations are equal. This test is based on the ratio of the two sample variances, which is calculated by dividing the difference between the two sample variances by the difference between the two sample means. This ratio is then compared to the value of a critical statistic to determine whether or not the two population variances are statistically equal. If the ratio is greater than or equal to the critical statistic, then the two population variances are considered equal. If the ratio is less than the critical statistic, then the two population variances are considered unequal. This test is useful for determining if the two populations have similar amounts of variation or if one population has more variation than the other.

To the nearest of tenth hour kwan has driven total 234 miles.

Speed is the pace at which an object's position changes in any direction. The distance travelled in relation to the time it took to travel that distance is how speed is defined. Since speed simply has a direction and no magnitude, it is a scalar quantity.

Speed= distance/time

Based on his speed and the distance driven within that time, Kwan will have driven 234 miles

First find out Kwan's speed per hour:

Speed = Distance / Time

Convert the time to decimals:

= 1 + 1/10 hours

= 1 + 0.1

= 1.1 hours

Speed:

= 234 / 1.1

= 212 miles per hour

In tenth of an hours therefore, Kwan would have gone:

= 212*1.1 hours

= 234 miles

Therefore,Kwan would have driven 234 miles.

We will discover that the probability that you will at random wind up with an orange hat is as follows: P = 1/12

Observe how we arrived at that now:

4 pieces of clothing (shirt, pants, socks, or hat)

three hues (purple, blue, or orange)

The color of only one item of clothing will change. The likelihood that you will receive an orange hat is what we are looking for.

We must first determine the likelihood that you will choose a hat at random. The likelihood of picking your hat at random is if all the apparel has the same probability of being chosen, just one more than the number of options (4). p = 1/4

The color is now chosen at random using the same methodology as before, with the likelihood that orange will be chosen at random being: q = 1/3.

When we multiply the individual probabilities by the joint probability, we obtain:

P = q*p = (1/4)*(1/3) = 1/12

Answer: 114 red marbles

Step-by-step explanation:

We know that for every 20 marbles, there are 19 red and 1 black marble.

The solutions to the quadratic equation 8x² - 3x = 5 are x = 1 and x = -5/8

From the question, we have the following parameters that can be used in our computation:

8 x squared - 3 x = 5

Express properly

So, we have

8x² - 3x = 5

This gives

8x² - 3x - 5 = 0

The quadratic formula is represented as

x = (-b ± √[b² - 4ac])/2a

Substitute the known values in the above equation, so, we have the following representation

x = (3 ± √[(-3)² - 4 * 8 * -5])/(2 * 8)

Evaluate

x = (3 ± √169)/16

So, we have

x = (3 ± 13)/16

Expand

x = (3 + 13)/16 and x = (3- 13)/16

Evaluate

x = 1 and x = -5/8

Hence, the solution is x = 1 and x = -5/8

On the 19th day, the lily pad covered half the pond.

The reason behind this is, If the lily pad doubles in size every day, then on the 20th day it will be twice as large as it was on the 19th day. That means it was already covering half the pond on the 19th day.

In this puzzle, the water lily is described as doubling in size every day. This means that on the first day, the lily pad is small, but by the second day, it has doubled in size.

If the null hypothesis is true in a chi-squared test, then we expect the test statistic to be approximately equal to its expected value.

In a chi-squared test, the null hypothesis is the statement that there is no significant association between two variables. If the null hypothesis is true, then we expect the test statistic to be approximately equal to its expected value. The expected value is calculated using the degrees of freedom and the expected frequency of each category in the contingency table.

The chi-squared test statistic is calculated by subtracting the observed frequency from the expected frequency for each category and then squaring the result. These squared differences are then summed across all categories to calculate the chi-squared test statistic.

If the null hypothesis is true, we expect the test statistic to be close to its expected value. This is because when the null hypothesis is true, the observed frequencies should be close to the expected frequencies. Therefore, the squared differences should be small, resulting in a small test statistic.

By solving the system of equation, length of flag = 1290ft and width = 1030 ft.

An equation is a mathematical statement that shows the equality of two expressions. An equation typically consists of two expressions separated by an equals sign (=), and it states that the expressions are equal in value.

The substitution method is a technique for solving a system of equations, which is a set of two or more equations that contain multiple variables. The goal of the substitution method is to find the values of the variables that make all of the equations in the system true simultaneously.

To solve a system of equations using the substitution method, you follow these steps:

Identify one of the equations that contains only one variable.

Solve that equation for that variable.

Substitute the expression you found for the variable into the other equation(s) in the system.

Solve the resulting equation(s) for the remaining variable(s).

Substitute the values you found for the variables back into one of the original equations to check your solutions.

To find the width and length of the flag, we can set up the following system of equations:

width + length = 2,320

length = width + 260

We can solve this system of equations by substitution. First, we can solve for width in the second equation by subtracting 260 from both sides:

length - 260 = width

Then, we can substitute this expression for width into the first equation:

(length - 260) + length = 2,320

2 * length - 260 = 2,320

2 * length = 2,580

length = 1,290

Now that we know the value of length, we can substitute it back into the second equation to find the value of width:

length = width + 260

1,290 = width + 260

width = 1,030

By applying the concept of algebra, it can be concluded that the two cost plans will be the same after 125 minutes.

The use of algebra in everyday life.

Algebra is a branch of mathematics that uses numbers, symbols, or letters to solve a mathematical problem. In everyday life, algebra is often used for financial planning, plan or scheme comparison, and so on.

In the given problem, we are asked to compare the two calling plans.

Let's say the total cost for the first plan is P1, then:

P1 = monthly fee + total cost per minute

   = 20 + (0.08 x number of minutes)

The total cost for the second plan is P2, then:

P2 = monthly fee + total cost per minute

    = 25 + (0.04 x number of minutes)

Let's say the two total costs become equal after x minutes, then we can equate the two expressions given above as follows:

   20 + 0.08x = 25 + 0.04x

0.08x - 0.04x = 25 - 20
