Step-by-step explanation: Your answer can't be simplified. So, your answer is 8/15 because your answer can't be simplified.

1) Simplified form of expression is, 0.533

2) The solution is, 8/15

Now, We can simplify 8/15 as,

8 / 15

After divide we get;

8/15 = 0.533

And, We have to simplify the expression,

= 2/3 x 4/5

= 8 / 15

Therefore, We get;

1) Simplified form of expression is, 0.533

Answer: Option A is the correct answer

Step-by-step explanation: I took the test and got it right

The total weight of the two animals is 1.19 x 10³ lbs. So the correct option is B.

Given approximate weights of the two animals are as:

1. 5.12 x 10² lbs

2. 6.8 x 10² lbs

We need to find the total weight of the two animals.

Step 1: Add the weights together:

5.12 x 10² lbs + 6.8 x 10² lbs

Step 2: Perform the addition:

(5.12 + 6.8) x 10² lbs

11.92 x 10² lbs

Step 3: Express the result in scientific notation with the correct number of significant digits:

The first number, 11.92, has three significant digits. To maintain three significant digits in the final answer, we can express it as 11.9 (rounding to the nearest tenth) and adjust the exponent accordingly:

11.9 x 10² lbs

This matches option 2 from your provided answers:

2. 1.19 x 10³ lbs.

So, the correct answer is: 1.19 x 10³ lbs.

Part A: To calculate the measures of center, we can find the median and the mean for each school.

For Bay Side School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 25, so the median class size is 25.

To find the mean class size for Bay Side School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 12 + 12 + 12 + 14 + 15 + 15 + 16 + 16 + 18 + 18 + 20 + 20 + 23 + 25 + 25 = 243. There are 15 classes, so the mean class size is 243/15 ≈ 16.2.

For Seaside School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 15, so the median class size is 15.

To find the mean class size for Seaside School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 10 + 10 + 10 + 11 + 12 + 15 + 15 + 16 + 17 + 17Part A (continued):

18 + 18 + 20 + 20 + 25 = 222. There are 14 classes, so the mean class size is 222/14 ≈ 15.9.

Therefore, the measures of center for Bay Side School are: median = 25, mean ≈ 16.2.

The measures of center for Seaside School are: median = 15, mean ≈ 15.9.

Part B: To calculate the measures of variability, we can find the range and the interquartile range (IQR) for each school.

For Bay Side School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 12, so the range is 25 - 12 = 13.

To find the IQR for Bay Side School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 15 and Q3 is 20. Therefore, the IQR is 20 - 15 = 5.

For Seaside School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 10, so the range is 25 - 10 = 15.

To find the IQRPart B (continued): for Seaside School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 12 and Q3 is 18. Therefore, the IQR is 18 - 12 = 6.

Therefore, the measures of variability for Bay Side School are: range = 13, IQR = 5.

The measures of variability for Seaside School are: range = 15, IQR = 6.

Part C: If you are interested in a smaller class size, Seaside School is a better choice because its measures of center are lower than those of Bay Side School, indicating that its class sizes tend to be smaller on average. Additionally, Seaside School has a smaller range and IQR, indicating less variability in class size. Therefore, there is less chance of encountering very large classes at Seaside School compared to Bay Side School.

The third angle measures 70° and it is an acute isosceles triangle. Then the correct options are C, E, and F.

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.

Create a triangle with angles of 40° and 70° on a sheet of paper using a protractor.

The third angle of the triangle is calculated as,

⇒ 180° - 40° - 70°

⇒ 180° - 110°

⇒ 70°

If the two angles are the same, then the triangle is an isosceles triangle.

The third angle measures 70° and it is an acute isosceles triangle. Then the correct options are C, E, and F.

*then multiply line 2). by the first number of line 1).

1). (2x+3y = 134 ) x 3 = (6x + 9y = 402)

Answer:

Step-by-step explanation:

The surface area of a cylinder can be calculated using the formula:

SA = 2πr^2 + 2πrh

where r is the radius of the base of the cylinder, h is the height of the cylinder, and π is approximately equal to 3.14.

Looking at the given diagram, we can see that the height of the cylinder is 10 cm and the radius of the base is 6 cm.

So, substituting these values into the formula:

SA = 2π(6)^2 + 2π(6)(10)

SA = 2π(36) + 2π(60)

SA = 72π + 120π

SA = 192π

Using a calculator, we can approximate this value to:

SA ≈ 602.88 cm^2

Therefore, the surface area of the cylinder is approximately 602.88 cm^2.

Answer:

\(f^{-1}\left(f(576)\right)=\boxed{576}\)

\(f^{-1}(-7)+f(-7)=\boxed{13}\)

Step-by-step explanation:

The inverse of an invertible function with the domain of all real numbers is obtained by reflecting the original function across the line y = x, which swaps the input and output values of the function. Therefore, (x, y) → (y, x).

Given table:

\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&-7&11&-13&6&5&-9\\\cline{1-7}\vphantom{\dfrac12}f(x)&7&12&8&-7&13&5\end{array}\)

Inverse function:

\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&7&12&8&-7&13&5\\\cline{1-7}\vphantom{\dfrac12}f^{-1}(x)&-7&11&-13&6&5&-9\end{array}\)

If we have a function f(x), the inverse function is denoted as f⁻¹(x), and it has the property that f⁻¹(f(x)) = x for all valid inputs x in the domain of f(x).

Therefore:

\(\large\boxed{f^{-1}\left(f(576)\right)=576}\)

The value of f(-7) is the value of f(x) when x = -7. Therefore, reading from the original table, f(-7) = 7.

The value of f⁻¹(-7) is the value of f⁻¹(x) when x = -7. Therefore, reading from the inverse function table, f⁻¹(-7) = 6.

Therefore:

\(\large\boxed{\begin{aligned}f^{-1}(-7)+f(-7)&=6+7\\&=13\end{aligned}}\)
