Answer:

x=28

Step-by-step explanation:

So first slove for the right angle triangle

a²+b²=c²

a=12 and c=15

12²+b²=15²

144+b²=225

b²=225-144

b²=81

b=√81

b=9

so now that you know the top two sides add 10 due to the lenght given on the bottom

9+10+9=28

Using the circumference of the circle, it is found that:

About 7.1 feet of railing needs to be replaced.

The circumference of a circle of radius r is given by:

\(C = 2\pi r\)

It is equivalent to 360º.

In this problem, the diameter is of 30 feet, hence the radius is 15 feet, so:

\(C = 2\pi (15) = 30\pi\)

Then, considering that the circumference is equivalent to 360º, the length to be replaced is given by:

\(L = \frac{27}{360} \times 30\pi = 7.1\)

About 7.1 feet of railing needs to be replaced.

Answer:

The average rate of change of a function over an interval is found by taking the difference between the function's values at the endpoints of the interval and dividing by the length of the interval. In this case, we have:

f(1) = -3(1)^3 + 7(1) = -3 + 7 = 4

f(3) = -3(3)^3 + 7(3) = -27 + 21 = -6

The average rate of change over the interval from x=1 to x=3 is therefore (-6 - 4) / (3 - 1) = -10 / 2 = -5.

To label your answer, you could write something like: "The average rate of change of the whale's movement over the interval from x=1 to x=3 seconds is -5 meters/second."

The constant of proportionality is 10 in the given graph which represents the total number of plants and number of seed packets used.

Equivalence between two ratios is referred to as proportionality in algebra. A and B are in the same proportion as C and D in the expression a/b = c/d. When one of a proportion's four quantities is unknown, a proportion is typically used to solve a word problem.

It is resolved by multiplying one numerator by the opposing denominator and equating the result to that of the other numerator and denominator. Any relationship that always has the same ratio is referred to as proportional.

For instance, the ratio of proportionality is the average number of apples per tree, and the quantity of apples in a crop is proportional to the number of trees in the orchard.

Here, when number of seeds packet is 1 plants are 10 and when seeds packet are 5 plants are 50, we can divide each of the variables to find the constant,

10/1 = 10

20/2 = 10

30/3 = 10

Thus, constant is 10 represented as y = kx

where y = no. of plants = 30

k = 10

x = no. of seeds packet = 3

The graph for the question is attached.

The answers are : mean = 0, standard deviation = 1, skewed to the right.

And the correct option is A.

The square root of the variance is used to calculate the standard deviation, a statistic that expresses how widely distributed a dataset is in relation to its mean.

Given:

The mean finish time for 48 racers who finished the grueling 50 km cross-country ski race at the Olympics is 2.164 hours,

and the standard deviation is 0.85 hours.

That means, we have;

μ = 2.164 and σ = 0.85

So, the z-score;

z = (\(\bar x\) - μ) / σ

z =  (\(\bar x\) - 2.164) / (0.85)

The mean of z-score is,

E(z) = E (\(\bar x\)) - μ / σ

E(z) = μ  - μ / σ

E(z) = 0 / σ

E(z) = 0

SD of z-score is,

SD (z) = SD(\(\bar x\)) - μ / σ

SD (z) = SD(\(\bar x\)) - 0 / σ

SD (z) = SD(\(\bar x\)) / σ

SD (z) = σ / σ

SD (z) = 1

Median of the distribution \(\bar x\) ≈ 2.13.

It responds to cumulative relative frequency of 0.50.

Median < mean

The coefficient of skewness is given by;

S = 3 (median - mean) / σ

S = 3 (2.164 - 2.13) / σ

S > 0

That means, the shape of the distribution of z - score is skewed to the right.

Therefore,  mean = 0, standard deviation = 1, skewed to the right.

Hello.

The first step is to use the Distributive Property and distribute 3:

3(n-1)<21

3n-3<21

Now, add 3 to both sides:

3n-3+3<21+3

3n<24

Divide both sides by 3:

n<8

Therefore, the answer is

Answer:

y = 5/2x -3

Step-by-step explanation:

Perpendicular lines have slopes that are negative reciprocals of one another

so slope is 5/2

Using (0,-3) => y = 5/2x + b

-3 = 5/2(0) + b

b = -3

y = 5/2x -3

a) The directional derivative of f(x, y) = xy along the unit vector d = 5i + 12j at the point (x0, y0) = (e, e) is 17e.

b) The directional derivative of f(x, y, z) = ex + yz along the unit vector d = (4, −3, 3) at the point (x0, y0, z0) = (1, 1, 1) is 1.

c) The directional derivative of f(x, y, z) = xyz along the unit vector d = (1, 0, −1) at the point (x0, y0, z0) = (1, 0, 1) is 0.

The directional derivative measures the rate at which a function changes along a specified direction. It is computed by taking the dot product of the gradient of the function with the unit vector representing the direction.

For part (a), the gradient of f(x, y) = xy is (∂f/∂x, ∂f/∂y) = (y, x), and at the point (e, e), it becomes (e, e). Taking the dot product of this gradient with the unit vector (5, 12) gives 5e + 12e = 17e.

For part (b), the gradient of f(x, y, z) = ex + yz is (∂f/∂x, ∂f/∂y, ∂f/∂z) = (e, z, y), and at the point (1, 1, 1), it becomes (e, 1, 1). Taking the dot product of this gradient with the unit vector (4, -3, 3) gives 4e - 3 + 3 = 1.

For part (c), the gradient of f(x, y, z) = xyz is (∂f/∂x, ∂f/∂y, ∂f/∂z) = (yz, xz, xy), and at the point (1, 0, 1), it becomes (0, 0, 0). Taking the dot product of this gradient with the unit vector (1, 0, -1) gives 0.

The differences they would have E: The sample sizes would be different.

The difference between the 95% and 98% confidence intervals lies in the level of precision desired. A 98% confidence interval would be wider than a 95% confidence interval because it has to accommodate a larger range of possible values. However, the formula for calculating confidence intervals takes into account both the desired level of precision and the sample size. As the desired level of precision increases (from 95% to 98%), the required sample size also increases.

Therefore, the only difference between the two confidence intervals would be the sample size. The standard errors, t-statistics, z-statistics, and point estimates of the population mean would all be calculated using the same formula and values for both confidence intervals.

Option E is answer.
