Step-by-step explanation:

fg^-1 / g^2

= fg^(-1-2)

= fg^-3

= f / g^3.

Step-by-step explanation:

so, the question is, what is bigger : 4/5 or 9/11.

to do this we need to bring both fractions to the same denominator (bottom part).

the least common multiple of 5 and 11 is simply 55.

4/5 = (4/5) × (11/11) = 44/55

9/11 = (9/11) × (5/5) = 45/55

as 45/55 > 44/55, we know now that 9/11 > 4/5, and that the father had therefore traveled the farthest.

The double integral  ∬D f(x, y) dxdy = -35²⁸/₃₀

Given the double integral ∬D f(x, y) dxdy where D: y = x, y = x², x = 3. and f(x, y) is (x - y)

First, we find the points of intersection.

So, y = x, y = x²

x = x²

x - x² = 0

x(1 - x) = 0

x = 0 or 1 - x = 0

x = 0 or x = 1

So, we integrate x on the interval [0,1] ∪ [1,3]

So, we have that

∬Df(x, y) dxdy = ∬(x - y) dxdy

= ∬x dxdy - ∬y dxdy

= ∫x dx∫dy - ∫ydy∫dx

= ∫xydx - ∫dxy²/2

= ∫x(x - x²)dx - ∫dx(x - x²)²/2

= ∫x(x - x²)dx - ∫dx(x - x²)²/2

= ∫₀¹x²dx - ∫₀¹x³dx - ∫₁³x²dx/2 - ∫₁³2x³dx/2 + ∫₁³x⁴dx/2

= [x³/3]₀¹ - [x⁴]₀¹ - [x³]₁³/6 - [x⁴]₁³ + [x⁵]₁³/10

= [1³ - 0³] - [1⁴ - 0⁴] - [3³ - 1³]/6 - [3⁴ - 1⁴] + [3⁵ - 1⁵]/10

= 1 - 1 - [27 - 1]/6 - [81 - 1] + [243 - 1]/10

= 0 - 26/6 - 80 + 242/10

= - 26/6 - 80 + 242/10

= (-130 - 2400 + 726)/30

= -1078/30

= -35²⁸/₃₀

So, the double integral is -35²⁸/₃₀

The  R²  and  Ra²  values for the estimated regression equation relating the average number is 0.5646 and 0.4912.  If ERA is used as the dependent variable instead of average runs given up per inning pitched, the estimated regression equation does not provide a good fit to the data.

Using the given table, the estimated regression equation relating the average number of runs given up per inning pitched, average number of strikeouts per inning pitched, and average number of home runs per inning pitched is

Runs per IP = -1.213 + 9.432 (SO per IP) - 11.909 (HR per IP)

Using this equation, we can calculate the predicted values of runs per IP for each player in the table and compare them to the actual values. R^2 is a measure of how well the regression equation fits the data and is calculated as the proportion of the total variation in the dependent variable (runs per IP) that is explained by the independent variables (SO per IP and HR per IP).

Using the regression equation and the data in the table, we can calculate R² as follows

SSR = ∑(predicted runs per IP - mean runs per IP)² = 57.102

SSE = ∑(actual runs per IP - predicted runs per IP)²  = 44.033

SST = ∑(actual runs per IP - mean runs per IP)² = 101.135

R² = SSR / SST = 57.102 / 101.135 = 0.5646 (rounded to four decimal places)

Ra² is the adjusted R², which takes into account the number of independent variables in the regression equation and adjusts R² accordingly to penalize for overfitting. Ra² is calculated as follows

Ra² = 1 - (SSE / (n - k - 1)) / (SST / (n - 1))

where n is the sample size and k is the number of independent variables.

Using the values calculated above, we can calculate Ra² as follows

Ra²  = 1 - (44.033 / (21 - 2 - 1)) / (101.135 / (21 - 1)) = 0.4912 (rounded to four decimal places)

Therefore, R² is 0.5646 and Ra² is 0.4912.

If we use ERA as the dependent variable instead of runs per IP, we would need to estimate a new regression equation. However, since ERA is also based on runs given up per IP, it is likely that the new regression equation would provide a similar fit to the data. The quality of the fit would depend on the relationship between ERA, SO per IP, and HR per IP.

Answer: Angelia rides 23.33 miles in 5 days.

Step-by-step explanation:

Angelia lives 2 1/3 miles from school, which is equivalent to 2 + 1/3 = 2.333 miles. She rides her bicycle to school and back each day, so she travels twice the distance daily.

Daily distance = 2 × 2.333 miles = 4.666 miles

She does this for 5 days, so the total distance she rides in 5 days is:

Total distance = 4.666 miles/day × 5 days = 23.33 miles

So, Angelia rides 23.33 miles in 5 days.

Answer:23.5 miles (i think)

Step-by-step explanation:

If Angelia bikes 2 1/3 miles 2 times everyday that means she would ride about 4.7 miles per day. In 5 days she would ride 23.5 miles because 4.7 times 5 is 23.5

To calculate the surface area of a triangular pyramid, we need to find the area of each triangular face and add them together.

Using the formula for the area of a triangle (base x height / 2), we can find the area of one of the triangular faces:

base = 8 mm

height = 6.9 mm

area = (8 mm x 6.9 mm) / 2 = 27.6 mm²

Since there are four triangular faces, the total surface area of the pyramid is:

4 x 27.6 mm² = 110.4 mm²

Therefore, the surface area of this triangular pyramid is 110.4 mm².

There are infinitely many solutions to the system of equation x + 2y = 6

and 2x + 4y = 12.

Given the system of equation in the question:

Using the method of elimination, eliminate the variable x by multiplying the first equation by -2 and adding the resulting equation to the second equation. This gives us:

-2(x + 2y) = -2(6)

-2x - 4y = -12

2x + 4y = 12

False. The question is regarding summarizing data in a sample and the use of percentages for metric scale variables.

Percentages are typically used for categorical data, whereas metric scale variables are better summarized using measures of central tendency like mean, median, and mode. Percentages are more appropriate for variables with nominal or ordinal scales.

If the variable has a metric scale, we should use measures of central tendency (such as mean or median) and measures of dispersion (such as standard deviation or range) to summarize the data.

Approximately 4.75% of the population in Hawkins is living in poverty. and a family in Hawkins in the 90th percentile has an income of $109,400.

To determine the proportion of the population in Hawkins living in poverty, we need to find the area under the normal distribution curve to the left of the poverty level of $25,000. We can do this by standardizing the poverty level using the formula:

Z = (X - μ) / σ

Where X is the poverty level, μ is the mean income, and σ is the standard deviation. Plugging in the values, we get:

Z = (25,000 - 75,000) / 30,000 = -1.67

Using a standard normal distribution table or calculator, we can find that the proportion of the population to the left of Z = -1.67 is 0.0475.

To find the income of a family in Hawkins in the 90th percentile, we need to find the income value that corresponds to a Z-score of 1.28. Again, using the standardization formula, we get:

Z = (X - μ) / σ

Let's start with calculating how much money is raised in total:

- Let's assume there are x SUVs and y cars.

- The cost for one SUV is $10 and the cost for one car is $5.

- Therefore, the total cost for all SUVs is 10x and the total cost for all cars is 5y.

- The total cost is the sum of these: 10x + 5y.

Now we need to calculate how much money each team will get. We know that:

- 25% of the money goes to the football team. This can be written as 0.25(10x + 5y) or 2.5x + 1.25y.

- 30% of the money goes to the soccer team. This can be written as 0.3(10x + 5y) or 3x + 1.5y.

- The remaining percent goes to the basketball team. This is 100% - 25% - 30%, which is 45%. This can be written as 0.45(10x + 5y) or 4.5x + 2.25y.

The probability that there will be no accidents during the first 2 weeks of January is calculated to be approximately 0.778 or 77.8%.

The first two weeks of January consist of 14 days, so we want to find the probability that no accidents occur in 14 days given that the probability of an accident occurring on any given day is 30/365. We can use the binomial distribution to solve this problem.

Let X be the number of accidents in 14 days. Then X follows a binomial distribution with n = 14 and p = 30/365. The probability of no accidents in 14 days is P(X = 0), which is given by the formula:

P(X = 0) = (n choose 0) x p⁰ x (1-p)⁽ⁿ⁻⁰⁾

where "n choose 0" is the number of ways to choose 0 accidents out of n days, which is simply 1.

Substituting n = 14 and p = 30/365, we get:

P(X = 0) = (1) x (30/365)⁰ x (1 - 30/365)⁽¹⁴⁻⁰⁾ ≈ 0.778

Therefore, the probability that there will be no accidents during the first 2 weeks of January is approximately 0.778 or 77.8%.
