Though working with laws of exponents, when part of the exponential equations with the same base, the exponent need to be subtracted.

Since the Quotient of Powers rules is utilized to decrease the number of terms when parts like terms with exponents. In arrange to urge the solution, fair remove the exponents whereas dividing the terms with the same base is appropriate for exponents with the same bases. when powers are multiplied, for two whole numbers of the same bases the exponents are added, while when powers are divided for two whole numbers of the same bases, exponents are subtracted. When any number is raised to the power of zero it comes about in 1 is the zero exponent rule.

Null hypothesis: The mean number of points scored by the taller team is not significantly different from the population mean of 72.

Alternative hypothesis: The mean number of points scored by the taller team is significantly greater than the population mean of 72.

Since the population variance is unknown, we will use a t-test. The degrees of freedom for this test will be 9 (n-1), where n is the sample size of the taller team (10).

Using an alpha level of 0.05 and 9 degrees of freedom, the critical t-value is 1.833.

To calculate the test statistic, we first need to find the sample mean and standard deviation of the taller team's scores. The sample mean is 82, and the sample standard deviation is 9.89. Using these values, we can calculate the t-value:

t = (82-72) / (9.89 / sqrt(10)) = 3.19

Since the calculated t-value (3.19) is greater than the critical t-value (1.833), we reject the null hypothesis and conclude that there is a significant difference between the mean number of points scored by the taller team and the population mean of 72. The coach can therefore conclude that having a taller team does result in a greater number of points scored.

Answer:

The linear equation satisfying the given condition is,

\(x=t+15\)

where x is Ravi's age and t is the number of years

(after 10 years (t=10) his age becomes 25)

Step-by-step explanation:

Let x be Ravi's age

Now, his  current age is unknown, but if you add 10 to it, then it becomes 25, so

x + 10 =25

so, his current age is x = 25 =10

x = 15

Now, we find the linear equation satisfying the given condition,

Let t be the number of years that have passed since the present time

so, if 0 years have passed, his age will be 15 years

after 1 year, his age will be 16 years

after 10 years, his age will be 25 years and so on

so

\(x = t + 15\)

this satisfies the given condition, since if we add ten years i.e t = 10,

then we get 25

The equation is:

Work/explanation:

Here's the linear equation for Ravi's age.

Ravi's age is x.

If you add 10 to x you get x + 10.

That gives 25.

So the linear equation is x + 10 = 25.

Answer: The function for estimating the population of wolves in an area is f(x) = 23 + 36 * log(x + 2) where x is the number of years since 2010.

Step-by-step explanation: To write the function in terms of common logarithms, we use the change of base formula:

log_a(b) = log_c(b) / log_c(a)

where a is the new base, b is the original value, and c is the common base (usually 10).

Using this formula, we can rewrite the function as:

f(x) = 23 + 36 * log_10(x + 2)

f(x) = 23 + 36 * (log(x + 2) / log(10))

f(x) = 23 + 36 * (log(x + 2) / 1)

f(x) = 23 + 36 * log(x + 2)

The given function is f(x) = 23 + 36 * log(base e)(x + 2), where x is the number of years since 2010 and f(x) is the estimated number of wolves in the area. Using the change of base formula for logarithms, we can rewrite the function in terms of common logarithms, which is log(base 10). This makes it easier to work with since we are generally more familiar with the base 10 system.

To do this, we first rewrite the formula using the change of base formula for logarithms as f(x) = 23 + 36 * (log(base 10)(x+2) / log(base 10)(e)). Simplifying the right side of the equation, we know that log(base 10)(e) is equal to approximately 0.434. So we can simplify the function further by multiplying the natural logarithm of (x+2) by 36/0.434, which produces the function f(x) = 23 + 82.93 * log(base 10)(x+2).

Finally, we can simplify this expression further by replacing 82.93 with 36/log(base e)(10) = 36/2.303 = 15.624. This gives us the final form of the function in terms of common logarithms: f(x) = 23 + 15.624 * log(base 10)(x+2).

Hope this helps, and have a great day!

The regression equation that fits the scenario will be y = 11.46 e1.107x

Utilizing this method with the provided information, we attain the regression equation:

ln y = 2.4502 + 0.0515x

It should be noted that to find the exponential equation, we can elevate both sides of the equation:

y = e^(2.4502 + 0.0515x) = 11.46 * e^(1.107x)

Consequently, the mathematical model that is most suitable for the mentioned data is:

y = 11.46 * e^(1.107x)

The coefficient of determination (R-squared) for said model is 0.994, thus indicating an incredibly strong fit.

Step-by-step explanation:

Graphing y = 28x - x^2 with it's limit interval (0<x<28). They ask for four sub-interval of LRAM.

Divide the base of 28 into 4 equal rectangles.

Area = (Base * Height) + (Base * Height) + (Base * Height) + (Base * Height)

Area = (0 * 7) + (147 * 7) + (196 * 7) + (147 * 7)

Area = 3430

What is solving an equation?

Unifying Principle for Equation Solving

By deleting parenthesis and grouping like terms, each side of the equation can be made simpler.

The variable term on one side of the equation can be separated using addition or subtraction.

To find the variable, use multiplication or division.

Consider, the given equation

     5(2x - 4) = 10

      10x - 20 = 10                                  Removing parenthesis

10x -20 + 20 = 10 + 20                         Adding 20 on both sides

              10x = 30                                 Simplifying

                  x = 3                                    Dividing both sides by 10

Hence, the value of x is, x = 3.
