Answer:

5 ^15

Step-by-step explanation:

(5 ^3)^5 =5 ^(3×5)=5 ^15

The rule used is (a^b)^c = a^(b*c)

If you raise some exponential expression to another exponent, then you multiply the exponents. You keep the base the same.

In this case, a = 5, b = 3, c = 5.

Using a calculator,

5^15 = 30,517,578,125

But it's likely your teacher will want you to keep the answer in exponential form since it's easier to work with.

Answer:y=2x-15

Step-by-step explanation:

First, we find the slope of the first line
Slope equation:

\(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)

Plug-in values

\(\frac{6-2}{6-(-2)}\)

=\(\frac{4}{8}\)=\(\frac{1}{2}\)

Slope=1/2

Remember that parallel lines have the same slope.

Now, we use the slope to get the y-intercept.

We start from (8,-1)

We go up 1 (rise) and right 2 (run), or the opposite of the slope (-1 rise, -2 run).

We get a y-intercept of -5.

Plug into y=mx+b

y=1/2x-5

Yes, the data provides strong evidence supporting the claim that the current audience share for WXYZ is higher than last year's 25 percent share. This is indicated by the calculated test statistic (z-value) of 5.31 and the corresponding p-value of 0.000, which is less than any of the specified significance levels (0.10, 0.05, 0.01, and 0.001). Therefore, we reject the null hypothesis (H0) and conclude that there is significant evidence to support the belief that the current audience share for WXYZ is higher than 25 percent.

In the given scenario, the objective is to determine if there is evidence supporting the claim that the current audience share for WXYZ is higher than last year's 25 percent share. Here is the explanation:

(a) The null hypothesis (H0) states that the current proportion (p) of viewers watching WXYZ is less than or equal to 25 percent, while the alternative hypothesis (Ha) states that the current proportion is greater than 25 percent.

H0: p ≤ 0.25 versus Ha: p > 0.25

(b) Using the MINITAB output, we observe that the sample proportion is 0.365, and the corresponding z-value is 5.31. The p-value associated with this test is 0.000.

At the significance levels of 0.10, 0.05, 0.01, and 0.001, the evidence against the null hypothesis is extremely strong, and we reject H0 in favor of Ha.

There is substantial evidence indicating that the current audience share for WXYZ is higher than last year's 25 percent share.

Answer:

18.8 years

Step-by-step explanation:

8% of $2000 = $160

To be worth $5000, the painting need to rise by $3000
And every year it rise by $160, so it will need 3000 : 160 = 18.75 (round to 18.8) years.

The percent decrease in price of gasoline would be 34.14%.

The formula for calculating percent decrease in price is given below:

Percent decrease = (Decrease in price / Original price) x 100

Here, the decrease in price is 1.28, and the original price is 2.45.

Therefore,

Percent decrease = (1.28 / 2.45) x 100

Percent decrease = 52.24%

However, this is the percentage of decrease in price from the original price.

We have to find the percentage decrease in price from the price a year before.

If the price a year before was 2.45 + 1.28 = 3.73,

then the formula for percentage decrease in price from the price a year before would be as follows:

Percent decrease = ((3.73 - 2.45) / 3.73) x 100

Percent decrease = 34.14%

To determine the percentage of students who read more than 8 books in Ms. Ryan's class, we need additional information regarding the total number of students and the number of students who read more than 8 books.

Without knowing the total number of students in Ms. Ryan's class or the number of students who read more than 8 books, it is not possible to calculate the exact percentage. To determine the percentage, we would need to know the numerator (number of students who read more than 8 books) and the denominator (total number of students).

Once we have the total number of students and the number of students who read more than 8 books, we can calculate the percentage by dividing the number of students who read more than 8 books by the total number of students, and then multiplying by 100. if there were 30 students in Ms. Ryan's class and 12 students read more than 8 books, the percentage would be (12/30) * 100 = 40%. This means that 40% of the students in Ms. Ryan's class read more than 8 books.

The probability of obtaining a sample mean greater than 92.25 WPM is extremely small, approaching zero.

We can use the Central Limit Theorem to solve this problem, since we have a large sample size (n=6666) and a known population mean (μ=8989) and standard deviation (σ=1616).

The Central Limit Theorem states that the distribution of the sample means will be approximately normal with a mean of μ and a standard deviation of σ/√n.

So, for this problem:

We want to find the probability that the sample mean would be greater than 92.25 WPM, which we can convert to a z-score using the formula z = (x - μ) / (σ / √n), where x is the sample mean.

z = (92.25 - 8989) / (1616 / √6666) = -116.45

Now, we can use a standard normal distribution table or a calculator to find the probability that a standard normal random variable is greater than -116.45. Since this probability is extremely small (essentially zero), we can conclude that the probability of getting a sample mean greater than 92.25 WPM is also essentially zero.

Therefore, the answer to the problem is that the probability of getting a sample mean greater than 92.25 WPM is essentially zero, or very close to 0.

The slope of the line that divides the region bounded by the parabola \(y=5x-3x^2\)and the x-axis into two regions with equal area is 5.

To find the slope of the line that divides the region into two equal areas, we need to determine the point of intersection between the parabola and the x-axis. Since the line passes through the origin, its equation will be y = mx, where m represents the slope.

Setting the equation of the parabola equal to zero, we find the x-values where the parabola intersects the x-axis. By solving the equation\(5x - 3x^2 = 0\), we get x = 0 and x = 5/3.

To divide the region into two equal areas, the line must pass through the midpoint between these x-values, which is x = 5/6. Plugging this value into the equation of the line, we have y = (5/6)m.

Since the areas on both sides of the line need to be equal, we can set up an equation using definite integrals. By integrating the equation of the parabola from 0 to 5/6 and setting it equal to the integral of the line from 0 to 5/6, we can solve for m. After performing the integration, we find that m = 5.

Therefore, the slope of the line that divides the region into two equal areas is 5.

Step-by-step explanation:

Can you please show the triangle?

Caleb's height increased by 8.33%. The initial height of Caleb was 60 inches, and his final height is 65 inches.

To calculate the percentage increase in Caleb's height, we need to find the difference between his final height and initial height, and then express it as a percentage of his initial height.

The initial height of Caleb was 60 inches, and his final height is 65 inches.

To find the difference in height, we subtract the initial height from the final height:

Height increase = Final height - Initial height

Height increase = 65 inches - 60 inches

Height increase = 5 inches

Next, we calculate the percentage increase by dividing the height increase by the initial height and multiplying by 100:

Percentage increase = (Height increase / Initial height) * 100

Percentage increase = (5 inches / 60 inches) * 100

Percentage increase ≈ 8.33%

Therefore, Caleb's height increased by approximately 8.33%.

The fully expanded and simplified form of (x - 2)(2x + 4) is 2(x - 2)(x + 2).

Expanding a bracket means multiplying the terms inside the bracket by the term(s) outside the bracket. In the case of (x - 2)(2x + 4), we can use the FOIL method to expand the brackets:

F: Multiply the First terms in each bracket, which gives us x * 2x = 2x²

O: Multiply the Outer terms in each bracket, which gives us x * 4 = 4x

I: Multiply the Inner terms in each bracket, which gives us -2 * 2x = -4x

L: Multiply the Last terms in each bracket, which gives us -2 * 4 = -8

Putting these results together, we get:

(x - 2)(2x + 4) = 2x² + 4x - 4x - 8

Notice that the -4x and +4x terms cancel out, so we're left with:

(x - 2)(2x + 4) = 2x² - 8

So the expanded form of (x - 2)(2x + 4) is 2x² - 8.

To simplify this expression further, we can factor out a 2:

2x² - 8 = 2(x² - 4)

And then factor the quadratic expression inside the parentheses:

2(x² - 4) = 2(x - 2)(x + 2)

So the fully expanded and simplified form of (x - 2)(2x + 4) is 2(x - 2)(x + 2).
