Answer:  27x² - 15xy - 24xz + 15yz - 3z².

The exponent that is understood on the base x in the given expression is; 1

The exponent of a number tells us how many times to use the number in a multiplication. Exponents are also called Powers or Indices. For example in the exponent form ab^(x), we can say that;

The base is a and its' exponent is 1.

Applying the above to our question gives us;

If the exponent form is xy^3, then we can say that;

The base is x.

We can see that there is no exponent attached to x and as such we will use 1 as 1 will still give us the value of x.

With given simple interest, the interest earned is $280 and the balance of the account after 4 years is $2280.

What is simple interest?

Simple interest is a way of calculating interest on a loan or investment that just considers the initial principle amount. Simply said, simple interest is a fixed percentage of the principle amount that is added to the initial amount over time.

I = P * r * t is the formula for simple interest.

Now,

a. The interest earned can be found using the formula:

I = P * r * t

Where I is the interest earned, P is the principal amount, r is the interest rate per year as a decimal, and t is the time in years.

In this case, P = $2000, r = 0.035, and t = 4.

I = 2000 * 0.035 * 4 = $280

Therefore, the interest earned on the sum is $280.

b. The balance of the account after 4 years can be found by adding the interest earned to the principal:

Balance = Principal + Interest

Balance = $2000 + $280 = $2280

Therefore, the balance of the account after 4 years is $2280.

The statement "Consistent system of equations has at least one solution, and an inconsistent system has no solution" is true.

In the context of systems of linear equations, a consistent system refers to a system where there exists at least one solution that satisfies all the equations in the system. This means that the equations can be simultaneously satisfied by a set of values for the variables.

On the other hand, an inconsistent system refers to a system of equations that has no solution. This occurs when the equations are contradictory or cannot be satisfied simultaneously by any values for the variables.

Therefore, a consistent system guarantees the existence of at least one solution, while an inconsistent system does not have any solution.

The independent variable in either a before/after t-test or a within-subjects ANOVA is always measured on a nominal or categorical scale.

This is because these statistical tests are used to compare means of two or more related groups, where the independent variable represents the different conditions or time points in which the dependent variable is measured.

For example, in a before/after t-test comparing the effectiveness of a medication, the independent variable would be the two time points (before and after), which are categorical in nature. Similarly, in a within-subjects ANOVA comparing three different treatment conditions, the independent variable would be the three treatment conditions, which are nominal in nature.

The value of x determined by Angle addition postulate is (x = 25).

As per the given questions;

The two angles are given as;

∠ABD = 5x + 10

and ∠DBC = 2x - 5

By the angle addition postulate;

The sum of both the angles will be 180.

Put the values;

∠ABD +  ∠DBC = 180

5x + 10 + 2x - 5 = 180

Simplifying;

7x + 5 = 180

7x = 180 - 5

7x = 175

x = 25.

Thus, the values of x is determined as the (x = 25).

Note that 3/20 can be scaled to a fraction that has a denominator of 100, making it easy to write the fraction as a decimal.

3/20 = 15/100 = 0.15

Step-by-step explanation:

we need to get 100 in denominator so last two options are discarded

multiply the fraction by 1/5 will change the number

we need to multiply with 1(5/5)

hence correct method is

multiply the fraction by 5/5 to get a denominator of 100 and then write the numerator as hundredths using a decimal point.

3/20*5/5

=3*5/(20*5)

=15/100

This means that we can be 99% confident that the true standard deviation of the weights of pennies is between 0.0216g and 0.0396g.

To estimate the true standard deviation of the weights of pennies with a 99% level of confidence.

we can use the formula for the confidence interval for a standard deviation, which is:

CI = (sqrt((n-1)*\(s^{2}\)/\(X^{2}\)_α/2), sqrt((n-1)*\(s^{2}\)/\(X^{2}\)_1-α/2))

Where CI is the confidence interval, n is the sample size (29 in this case).

s is the sample standard deviation (0.035g).

α is the significance level (0.01 for a 99% level of confidence).

\(X^{2}\)_α/2 is the chi-square value at α/2 with n-1 degrees of freedom.

\(X^{2}\)_1-α/2 is the chi-square value at 1-α/2 with n-1 degrees of freedom.

Substituting the values in the formula, we get:

CI = (sqrt((29-1)*0.035^2/\(X^{2}\)_0.005/2), sqrt((29-1)*0.035^2/\(X^{2}\)_0.995/2))

CI = (0.0216, 0.0396)

This means that we can be 99% confident that the true standard deviation of the weights of pennies is between 0.0216g and 0.0396g.

In conclusion, to estimate the true standard deviation of the weights of pennies with a 99% level of confidence, we use the formula for the confidence interval for a standard deviation and substitute the sample size, sample standard deviation, and significance level. The resulting confidence interval gives us a range of values within which we can be confident that the true standard deviation lies.

(d.) Each run of the simulation only provides a sample of the actual system's operation.

This assertion is right, not mistaken. Indeed, each simulation run is a sample of the actual system's operation. A single simulation run cannot account for all possible outcomes and variations in the real system because simulations are based on mathematical models and involve random variations.

In order to take into consideration various scenarios and variations, multiple simulation runs are typically carried out.

The

equation of the circle

is: (x - 5.9)^2 + (y - 6.7)^2 = 98

To find the equation of a circle, we use the formula:

(x - h)^2 + (y - k)^2 = r^2

where (h, k) represents the center of the circle, and r represents the radius.

Given that the circle has a radius of √98 units and is centered at (5.9, 6.7), we can substitute these values into the formula:

(x - 5.9)^2 + (y - 6.7)^2 = (√98)^2

Simplifying further:

(x - 5.9)^2 + (y - 6.7)^2 = 98

Therefore,

the equation of the circle is:

(x - 5.9)^2 + (y - 6.7)^2 = 98

This equation represents all the points on the plane that are equidistant from the center (5.9, 6.7) and have a distance of √98 units from the center.

Answer:

Step-by-step explanation:

Graphing window: [0, 30] by [-20, 160]

y1 = 20 + 2x + √(400 + 4x^2)

y2 = 1.6(20 + x + √(400 + x^2))

y1 = y2 when x = 24.3798.

So the length of the smaller garden's longer leg is about 24.38 feet.

The correct answer of the exponential function to represent the amount of money in the account after x number of years is y = 300(1.005)^x.

The exponential function to represent the amount of money in the account after x number of years when Santi invested $300 in an account that earned 0.5% interest is given by the formula: y = ab^x, where "a" represents the initial amount of investment, "b" represents the growth factor, and "x" represents the time period.

In this problem, Santi invested $300 which is the initial investment.

The account earned 0.5% interest, which is equivalent to 0.005 in decimal form.

Therefore, the growth factor is 1 + 0.005 = 1.005.

Using the formula for exponential functions, we can write: y = ab^x where a = $300 and b = 1.005

Therefore, y = 300(1.005)^x

Therefore, the exponential function to represent the amount of money in the account after x number of years is y = 300(1.005)^x.
