In the given diagram, using one of the circle theorems, the value of x is 68°

From the question, we are to calculate the value of x in the given diagram.

The diagram shows a circle with O. The angle subtended at the center is 136°. We are to determine the value of the unknown angle x.

From one of circle theorems, we have that

The angle subtended by arc at the center of a circle is twice the angle at the circumference.

Therefore,

We can write that

136° = 2x

Solve for x in the above equation

136° = 2x

Divide both sides of the equation by 2

136° / 2 = 2x / 2

68° = x

Hence,

x = 68°

Solving the equation​ √(x - 3)³ - 64 = 0 for the variable x gives x = 19

From the question, we have the following parameters that can be used in our computation:

√(x - 3)³ - 64

Express as an equation

So, we have

√(x - 3)³ - 64 = 0

Add 64 to both sides of the equation

√(x - 3)³ = 64

Take the cube roots of both sides

So, we have

√(x - 3) = 4

Square both sides of the equation

This gives

x - 3 = 16

Add 3 to the equation

x = 19

The 96% confidence interval for the population mean μ is approximately (18.06, 20.54).

We have,

To construct a 96% confidence interval about the population mean(μ) with a sample size of n = 57,

we can use the following formula:

CI = x ± z (s/√n)

where x is the sample mean, s is the sample standard deviation, n is the sample size, z is the z-score associated with the desired confidence level (96% in this case), and √n is the square root of the sample size.

The z-score corresponding to a 96% confidence level can be found using a standard normal distribution table or calculator.

For a two-tailed test, the z-score is 1.96.

Substituting the given values, we have:

CI = 19.3 ± 1.96 (4.8/√57)

Calculating the standard error of the mean (s/√n):

s/√n = 4.8/√57 ≈ 0.634

Substituting this value into the formula:

CI = 19.3 ± 1.96*0.634

Calculating the upper and lower bounds of the confidence interval:

lower bound = 19.3 - 1.96*0.634 ≈ 18.06

upper bound = 19.3 + 1.96*0.634 ≈ 20.54

Therefore,

The 96% confidence interval for the population mean μ is approximately (18.06, 20.54).

To construct a 96% confidence interval for the population mean, use the formula x ± z*(s/√n) with z being the z-score for the 96% level, x being the sample mean, s being the sample standard deviation, and n being the sample size. Substituting the given values will give the lower and upper bound of the confidence interval.

The question is asking for the construction of a 96% confidence interval for a population mean u, given a sample size (n) of 57, a sample mean (x) of 19.3 and a sample standard deviation (s) of 4.8.

To find the confidence interval, we need to use the formula: x ± z*(s/√n) where z is the z-score associated with our confidence level. For a 96% confidence interval, the z-score is approximately 2.05 (you can find this from a standard z-table).

Substituting the given values into the formula gives: 19.3 ± 2.05*(4.8/√57)

Calculating the above expression will give the lower and upper bound of the 96% confidence interval.

all the other sides of each triangle are radii, so they are all equal the 2 triangles are congruent.

>Both angles A =78

An angle from the radius is the same as the arc angle it creates.

The arc angle is double only if the angle touches the end of the circle not the radius.  that's why it's not 156

So, <BAC =78   so arc angle BC=78

The final velocity of the sled is 4.317 m/s.

Before the snow,

Total mass of sled = 35 + 4.2 = 39.2 kg

Initial velocity of the sled = 5 m/s

After the snow,

Total mass = 35 + 4.2 + 6.2 = 45.4 kg

The area under the curve (since the function of the parabolic expression is y = x - x²) is 1/6 square units.

A parabolic function has an expression represented as f(x) = ax² + bx + c, which allows solving for x using either the factorization method or applying the quadratic formula. By zeroing out this expression, it becomes possible to determine its roots as with any quadratic equation.

In the case of the above function:

To find the area under the curve, above the x-axis, we need to integrate the parabolic expression from 0-1

that is:

∫[0,1](x-x²)dx

This is evaluated using the power rule

∫[0,1](x-x²)dx = [1/2x² - 1/3x³) fro x= 0 to x = 1

inserting the limits of the integration, we have:

The person would have to invest approximately $461,044.94 now in an annuity with an annual interest rate of 3.1% to receive monthly payments of $1500 for 20 years.

To calculate the present value of an annuity, we can use the following formula:

[tex]PV = PMT \times \dfrac{(1 - (\dfrac{1}{(1 + r)^n})) }{ r}[/tex]

Where:

PV = present value of the annuity

PMT = monthly payment

r = annual interest rate

n = total number of payments

In this case, the PMT is $1500, the annual interest rate is 3.1%, and the number of payments is 20 years x 12 months per year = 240 payments.

First, we need to convert the annual interest rate to a monthly interest rate by dividing it by 12:

r = 3.1% / 12 = 0.2583%

Next, we can plug in the values and solve for PV:

PV = $1500 x [(1 - (1 / (1 + 0.2583%)²⁴⁰)) / 0.2583%]

PV = $1500 x [(1 - (1 / 1.002152²⁴⁰)) / 0.002583]

PV = $1500 x [(1 - (1 / 4.818681)) / 0.002583]

PV = $1500 x (0.7915 / 0.002583)

PV = $461,044.94
