Enter the power of 10 that makes an expression equivalent to 12,500.

The problem involves estimating the proportion of UQ (University of Queensland) students who have more than one television streaming service subscription. A study of 552 UQ students found that 266 of them had more than one subscription. We are asked to estimate the proportion with 82% confidence and report the lower bound of the interval as a percentage to two decimal places.

To estimate the proportion of UQ students with more than one television streaming service subscription, we can use the sample proportion as an estimate. The sample proportion is calculated by dividing the number of students with more than one subscription (266) by the total number of students in the sample (552).
Next, we calculate the margin of error using the formula: Margin of Error = Critical Value * Standard Error, where the critical value is obtained from the standard normal distribution for the desired confidence level. For an 82% confidence level, the critical value can be determined using a standard normal distribution table.
The standard error is calculated as the square root of (p * (1 - p) / n), where p is the sample proportion and n is the sample size.
Finally, we construct the confidence interval by subtracting the margin of error from the sample proportion to obtain the lower bound of the interval.
Reporting the lower bound of the interval as a percentage to two decimal places gives us the estimated proportion of UQ students with more than one television streaming service subscription.

The effective interest method is used to amortize the bond premium. The carrying value of the bond increases by the effective interest each period, and the premium is amortized over the life of the bond. The journal entry for bond issuance is as follows: Dr. Cash 205,000, Dr. Premium on Bonds Payable 5,000, Cr. Bonds Payable 210,000

The effective interest method is a method of amortizing bond premium or discount that takes into account the time value of money. The effective interest is the interest that would be earned if the bond were purchased at its market value and held to maturity. The carrying value of the bond increases by the effective interest each period, and the premium is amortized over the life of the bond.

The journal entry for bond issuance records the proceeds from the sale of the bonds, the premium on bonds payable, and the bonds payable. The proceeds from the sale of the bonds are equal to the face value of the bonds plus the premium.

The premium on bonds payable is a liability that represents the excess of the issue price of the bonds over their face value. The bonds payable account is a long-term liability that represents the amount that the company owes to the bondholders.

Therefore, if the input is angle_elev = 3.8 and shadow_len = 17.5, the estimated height of the tree would be approximately 1.166 meters.

To calculate the height of a tree given the angle of elevation (angle_elev) and the shadow length (shadow_len), you can use trigonometry.

Let's assume that the tree height is represented by the variable "tree_height". Here's how you can calculate it:

Convert the angle of elevation from degrees to radians. Most trigonometric functions expect angles to be in radians.

angle_elev_radians = angle_elev * (pi/180)

Use the tangent function to calculate the tree height.

tree_height = shadow_len * tan(angle_elev_radians)

Now, if the input is angle_elev = 3.8 and shadow_len = 17.5, we can plug these values into the formula:

angle_elev_radians = 3.8 * (pi/180)

tree_height = 17.5 * tan(angle_elev_radians)

Evaluating this expression:

angle_elev_radians ≈ 0.066322511

tree_height ≈ 17.5 * tan(0.066322511)

tree_height ≈ 1.166270222

Based on the given information, we cannot prove that △EFG and △KLM are similar using the SSS or SAS similarity theorems. The correct answer is option D) No, they cannot be proven similar by SSS or SAS.

To determine if the triangles △EFG and △KLM can be proven similar using the SSS (Side-Side-Side) or SAS (Side-Angle-Side) similarity theorems, we need to compare their corresponding sides and angles.

SSS Similarity Theorem states that if the lengths of the corresponding sides of two triangles are proportional, then the triangles are similar.

SAS Similarity Theorem states that if two corresponding sides of two triangles are proportional, and the included angles are congruent, then the triangles are similar.

Let's examine the given information:

Side lengths of △EFG: EF = 18, EG = 24, FG = 15.

Side lengths of △KLM: KL = 6, KM = 8, LM = 5.

By comparing the side lengths, we can see that they are not proportional. For example, the ratio of EF/KL is 18/6 = 3, while the ratio of EG/KM is 24/8 = 3. Therefore, the corresponding sides of △EFG and △KLM are not proportional, which means we cannot establish similarity using the SSS theorem.

Now, let's consider the SAS theorem. For this, we also need to compare the included angles.

Angles of △EFG: ∠EFG, ∠EFG, ∠EGF.

Angles of △KLM: ∠KLM, ∠KML, ∠KLM.

The given information states that ∠EFG and ∠KLM are congruent. However, we don't have any information about the other angles. Without knowing the congruency of the remaining angles, we cannot establish similarity using the SAS theorem

Larger angle = 62 degrees

Smaller angle = 28 degrees

Explanation:

Let the two complementary angles be x and y. Since the sum of complementary angles is 90degrees, hence;

x + y = 90 ....1

Let the larger angle be x and the smaller angle be y;

If the larger angle is 34° larger than the smaller angle,

x = 34 + y .....2

Substitute equation 2 into 1;

34+y+y = 90

34 + 2y = 90

2y = 90 - 34

2y = 56

Divide both sides by 2

2y/2 = 56/2

y = 28

Substitute y = 28 into equation 2;

x = 34 + 28

x = 62 degrees

Hence the measure of both anglea (x, y) is (62, 28)

A result is called "statistically significant" when the p-value is less than the significant level, typically 0.05.

This means that there is less than a 5% chance that the results are due to chance alone, and suggests that there is a real effect present in the data.

The Null Hypothesis is the assumption that there is no significant difference between the measured phenomenon and a certain value or set of values. A statistically significant result means that the observed data are inconsistent with the assumption of no difference, or no effect.

The given equation, y = x + 3, is not a logarithmic function. A logarithmic function is a type of function where the variable appears as the exponent of a fixed base.

To determine if a function is logarithmic, we need to check if the variable is the exponent. In the given equation, the variable x appears as an additive term with a constant value of 3. It is not the exponent of any base. Therefore, y = x + 3 is not a logarithmic function.

An example of a logarithmic function is y = log(base 2)(x), where the variable x appears as the exponent with a fixed base of 2. In this function, the logarithm helps us find the power to which 2 must be raised to obtain x.

The slope of the tangent line to is approximately equal to tangent of 6 radians.

To find the slope of the tangent line to the polar curve r = 8 sin(θ) at the point specified by the value of θ = 6, we need to find the derivative of the polar curve with respect to θ and evaluate it at θ = 6.

First, we can find the derivative of r with respect to θ:

dr/dθ = 8 cos(θ)

Then, we can find the value of r at θ = 6:

r(6) = 8 sin(6)

To find the slope of the tangent line at θ = 6, we can use the formula:

dy/dx = (dr/dθ * sin(θ) + r * cos(θ)) / (dr/dθ * cos(θ) - r * sin(θ))

Substituting the values we found above, we get:

dy/dx = (8 cos(6) * sin(6) + 8 sin(6) * cos(6)) / (8 cos(6) * cos(6) - 8 sin(6) * sin(6))

Simplifying this expression, we get:

dy/dx = tan(6)

Therefore, the slope of the tangent line to the polar curve r = 8 sin(θ) at the point specified by the value of θ = 6 is approximately equal to the tangent of 6 radians.

Answer:

a. 90

b. 70

Step-by-step explanation:

What we need to do here is make substitutions for x.

We proceed as follows;

P(x) = 20cos60x + 80

x is the number of horses since 2009, so for 2010, x = 2010-2009 = 1

Substitute this;

P(x) = 20Cos60(1) + 80 = 20Cos60 + 80 = 10 + 80 = 90

Kindly recall that cos 60 = 0.5

For 2025, x = 2025 - 2009 = 16

Substitute this value;

P(x) = 20cos60(16) + 80

P(x) = 20cos960 + 80

Recall, cos960 = -0.5

P(x) = 20(-0.5) + 80

P(x) = -10 + 80

P(x) = 70

Step-by-step explanation:

\(x {}^{2} + 3x - 18 \\ = x {}^{2} + (6 - 3)x - 18 \\ = x {}^{2} + 6x - 3x - 18 \\ = x(x + 6) - 3(x + 6) \\ = (x + 6)(x - 3)\)
