The standard deviation of the sampling distribution is approximately 0.3292.

The behaviour of the sampling distribution of the mean is described by the central limit theorem, a key conclusion in statistics. It asserts that regardless of how the population distribution is shaped, if a random sample of size n is taken from a population with mean and standard deviation, the distribution of sample means will tend towards a normal distribution as n increases.

Because it enables us to utilise the normal distribution to draw conclusions about the population mean based on sample means, the central limit theorem has significant practical ramifications. Additionally, it offers a foundation for confidence interval estimation and statistical hypothesis testing.

The standard deviation is given by the formula:

SD = σ/√(n)

Now, substituting the value of σ = 40, n = 147,400 we have:

SD = σ/√(n) = 40/√(147400) ≈ 0.3292

Hence, the standard deviation of the sampling distribution is approximately 0.3292.

Answer:

\(\sqrt{-(x +72)^3} - 72 = -(3\sqrt x - 72 +72)^3\)

Step-by-step explanation:

Given

\(g(x) = 3\sqrt x - 72\)

\(h(x) = -(x +72)^3\)

Required

Show that they are inverse functions

For g(x) and h(x) to be inverse, then:

\(g(h(x)) = h(g(x))\)

We have:

\(g(x) = 3\sqrt x - 72\)

Replace x with h(x)

\(g(h(x)) = 3\sqrt{h(x)} - 72\)

Substitute value for h(x)

\(g(h(x)) = 3\sqrt{-(x +72)^3} - 72\)

Similarly;

\(h(x) = -(x +72)^3\)

Replace x with g(x)

\(h(g(x)) = -(g(x) +72)^3\)

Substitute value for g(x)

\(h(g(x)) = -(3\sqrt x - 72 +72)^3\)

Recall that:

\(g(h(x)) = h(g(x))\)

So:

\(\sqrt{-(x +72)^3} - 72 = -(3\sqrt x - 72 +72)^3\)

(c) The intercepts are marked on the graph. The y-intercept is (0, 10); the x-intercept is (10, 0). These represent the temperature when the wind speed is 0, and the wind speed when the temperature is 0, respectively.

Answer:

y = -30

Step-by-step explanation:

Set the ratio: \(\frac{x_1}{y_1} = \frac{x_2}{y_2}\)

Let:

\((x_1 , y_1) = (-4 , 10)\\(x_2 , y_2) = (12 , y)\\\)

Plug in the corresponding terms to the corresponding variables:

\(\frac{-4}{10} = \frac{12}{y}\)

First, cross multiply.

\((-4 * y) = (10 * 12)\\-4y = 10 * 12\\-4y = 120\)

Next, isolate the variable, y. Divide -4 from both sides of the equation:

\(\frac{-4y}{-4} = \frac{120}{-4}\\y = \frac{120}{-4}\\y = -30\)

-30 is your answer for y.

Note that given the proof of congruence by SAS, the only thing remaining to know is that "2 corresponding sides and the corresponding included angles of both triangles are equal."

The definition of SAS Congruency is as follows:

The SAS postulate states that two sides and the included angle of one triangle are identical to the corresponding two sides and the included angle of another triangle.

As demonstrated in the triangle, the angles mCAD and mACB are congruent. Thus; m∠CAD ≅ m∠ACB

Because m∠CAD and m∠ACB are congruent, AD and BC must also be congruent. Now, because AC is shared by both triangles ABC and ADC, we get two matching equal sides with the included corresponding equal angles.

As a result, the SAS Congruence postulate is proven.

Answer:

where is the square at I cannot see it

Answer:

A. \(n=100\)
B. \(k=0\)

Step-by-step explanation:

A. The equation "110% n = 11" can be solved as follows:

110% n = 11

To solve for n, we need to get rid of the percentage sign (%). We can do this by dividing both sides of the equation by 110%, or 0.110 (since 110% is equivalent to 1.1 in decimal form).

(110% n) / 110% = 11 / 110%

n = 11 / 0.110

n = 100

So, the solution for n in the equation "110% n = 11" is n = 100.

B. The given equation is:

(328 x 128) x k = 328 x (82 x 128) x k

To solve for k, we can simplify the equation using the properties of multiplication.

Step 1: Perform the multiplications inside the parentheses:

41984 x k = 328 x 10576 x k

Step 2: Rearrange the equation by applying the associative property of multiplication:

41984 x k = 328 x (10576 x k)

Step 3: Divide both sides of the equation by 328:

(41984 x k) / 328 = 10576 x k

Step 4: Cancel out the common factor of k on the left-hand side:

(41984 / 328) x k = 10576 x k

Step 5: Simplify the left-hand side:

128 x k = 10576 x k

Step 6: Subtract 10576 x k from both sides of the equation to isolate k:

128 x k - 10576 x k = 0

Step 7: Factor out k on the left-hand side:

k x (128 - 10576) = 0

Step 8: Simplify further:

k x (-10448) = 0

Step 9: Divide both sides of the equation by (-10448):

k = 0

So, the solution for k in the equation "(328 x 128) x k = 328 x (82 x 128) x k" is k = 0.

Answer:

\(\frac{3}{4}\) miles

Step-by-step explanation:

Total length of the trail = \(4\frac{1}{2}\) miles = \(\frac{9}{2}\) miles

She ran the first \(\frac{2}{3}\) of the distance i.e.

The distance for which she ran = \(\frac{2}{3} \times \frac{9}{2} = 3\ miles\)

Remaining distance = Total length of trail minus the distance for which she has already run = \(\frac{9}{2} - 3 = \frac{3}{2}\) miles

Given that: After running, Annie has to walk due to steep nature of the trail, So, Annie walked for \(\frac{1}{2}\) of the remaining distance.

The distance for which Annie walked = \(\frac{1}{2} \times\) Remaining distance

The distance for which Annie walked = \(\frac{1}{2} \times\) \(\frac{3}{2}\) = \(\frac{3}{4}\) miles

So, the answer is: \(\frac{3}{4}\) miles

35 = 7r

35/7 = r

5 = r

OR

\(\rule[225]{225}{2}\)

Answer:

r = 5

Step-by-step explanation:

Given statement,

→ 7(q + 5) is equivalent to (q + r)7.

Forming the equation,

→ 7(q + 5) = 7(q + r)

Now we have to,

→ Find the required value of r.

Then the value of r will be,

→ 7(q + 5) = 7(q + r)

Applying Distributive property:

→ 7(q) + 7(5) = 7(q) + 7(r)

→ 7q + 35 = 7q + 7r

Cancelling 7q from both sides:

→ 35 = 7r

→ 7r = 35

Dividing the RHS with number 7:

→ r = 35/7

→ [ r = 5 ]

Therefore, the value of r is 5.

Answer:

∠DAB = 133°

Step-by-step explanation:

Given - Quadrilateral ABCD is a parallelogram. ∠D = 3x + 17, ∠B = 5x - 3

To find - What is the measure of ∠DAB?

Proof -

We know that In a parallelogram, opposite angles are equal.

So, ∠A = ∠C and ∠B = ∠D

Now,

As ∠B = ∠D

⇒3x + 17 = 5x - 3

⇒17 + 3 = 5x - 3x

⇒20 = 2x

⇒x = 10

So,

∠B = 5(10) - 3 = 50 - 3 = 47

⇒∠B = 47°

Also, we know that

∠A + ∠B = 180°

⇒∠A = 180° - ∠B

⇒∠A = 180° - 47° = 133°

⇒∠A = 133°

⇒∠DAB = 133°

The number of hours at which both companies' rental costs will be the same is nearly 6 hours.

Equations are statements in mathematics that have two algebraic expressions on either side of the equals (=) sign. It shows that the expressions displayed on the left and right sides have an equal connection. To determine the value of an unknown variable that stands in for an unknown quantity, equations can be solved.

Let the number of hours = h The deposit price at the first canoe rental company = $10

Cost per hour to rent a canoe = $8.25/h

The total cost for rental for the first company is given by

C(A) = 10 + 8.25h

The deposit price at the second canoe rental company = $12.50

Cost per hour to rent a canoe = $7.85/h

The total cost for rental for the second company is given by

C(B) = 12.50 + 7.85h

The number of hours at which both company's rental costs will be the same is given as

C(A) = C(B)

10 + 8.25h = 12.50 + 7.85h

8.25h - 7.85h = 12.50 - 10

0.4h = 2.5

h = 2.5/0.4

h = 6.25

h ≈ 6 hours

The first step is to find the values of x and y. From the information given,

x is the cost of an adult ticket and y is the cost of a child ticket. The system of equations is shown below

3x + 5y = 50

x + 5y = 31

From the second equation,

x = 31 - 5y

We would substitute x = 31 - 5y into 3x + 5y = 50. We have

3(31 - 5y) + 5y = 50

By expanding the parentheses, we have

93 - 15y + 5y = 50

- 15y + 5y = 50 - 93

- 10y = - 43

Dividing both sides of the equation by - 10,

- 10y/- 10 = - 43/- 10

y = 4.3

Substituting y = 4.3 into x = 31 - 5y, we have

x = 31 - 5 * 4.3 = 31 - 21.5

x = 9.5

If an adult ticket costs $9.5, then the cost of 4 adult tickets is
