Its option D

As, for red $12 is charged

So 35 x $12 = 420

And white is $10

So, 20 x 10 = $200

The value of tn–1,α/2 for constructing a 90% confidence interval with a sample size of 12 is approximately 1.796.

To find the value of tn–1,α/2 for a 90% confidence interval with a sample size of 12, we can use a t-distribution table or a calculator.

Using a t-distribution table with 11 degrees of freedom (12-1=11) and a 5% significance level (since we want a 90% confidence interval), we can find the value of tn–1,α/2 to be approximately 1.796.

Rounding this value to three decimal places, we get tn–1,α/2 = 1.796.

Therefore, to construct a 90% confidence interval with a sample size of 12, we would use the formula:

sample mean ± tn–1,α/2 * (sample standard deviation / sqrt(sample size))

where tn–1,α/2 = 1.796 and the sample mean and sample standard deviation are calculated from the data.

The tangent segments WX and YX are the same length. This can be proven by forming triangles WVX and YVX, and using the hypotenuse length rule to show the triangles are congruent.

So,

YX = WX

x-8 = 18

x = 18+8

x = 26

The result of applying the square root property of equality to this equation is x = (-b ± √(b² - 4ac)) / (2a)

If we apply the square root property of equality to the equation (x + (b/2a))² = (-4ac + b²)/(4a²), we get:

x + (b/2a) = ±√[(-4ac + b²)/(4a²)]

Next, we can simplify the expression under the square root:

√[(-4ac + b²)/(4a²)] = √(-4ac + b²)/2a

Now, we can substitute this expression back into our original equation:

x + (b/2a) = ±√(-4ac + b²)/2a

Finally, we can isolate x by subtracting (b/2a) from both sides:

x = (-b ± √(b² - 4ac)) / (2a)

This is the quadratic formula, which gives us the solutions for the quadratic equation ax² + bx + c = 0. By completing the square, we have derived this formula from the original quadratic equation.

The complete question is in the picture, please refer to the attached picture.

We have an inequality:

–3(2x – 5) < 5(2 – x)

-6x + 15 < 10 - 5x

6x -5x > 15 - 10

x > 5

or

x ∈ (5, ∞)

Also, the pseudocode is used to calculate total cost of item purchased by a customer .

From the Boxplot given:

JOB A :

median = 70

JOB B:

median = 30

JOB C :

median = 30

Hence, median income for Job A is greater than for Job B and C is True.

Minimum amount earned in Job A = 50.

However, some people earn above 50 and as much as 120 in Job C.

Hence, not everyone who does job A earns more than those in Job C.

Job C :

interquartile range = 80 - 20 = 60

Job A :

interquartile range = 98 - 60 = 38

Hence, the interquartile range for Job C is greater than for Job A. The statement is True.

The crude oil is likely to be paraffinic. Paraffinic crude oils are characterized by having a high API°, low Watson characterization factor, and low refractive index. They also tend to have a high surface tension.

Specific gravity at 60 °F: 0.88

API° at 60 °F: 28

Watson characterization factor: 1.014

Refractive index: 1.44

Surface tension: 20 dyne/cm

Paraffinic, naphthenic, or aromatic: Paraffinic

Specific gravity at 60 °F the specific gravity of a liquid is its density relative to the density of water. The specific gravity of crude oil is typically between 0.8 and 1.0. A specific gravity of 0.88 means that the crude oil is 88% as dense as water.

API° at 60 °F: The API°, or American Petroleum Institute gravity, is a measure of the lightness or darkness of crude oil. A higher API° indicates a lighter crude oil. A crude oil with an API° of 28 is considered to be a medium-heavy crude oil.

Watson characterization factor the Watson characterization factor is a measure of the aromaticity of crude oil. A higher Watson characterization factor indicates a more aromatic crude oil. A crude oil with a Watson characterization factor of 1.014 is considered to be a paraffinic crude oil.

Refractive index the refractive index of a liquid is a measure of how much light is bent when it passes through the liquid. The refractive index of crude oil is typically between 1.4 and 1.5. A refractive index of 1.44 indicates that the crude oil is slightly more refractive than water.

Surface tension the surface tension of a liquid is a measure of the force that acts at the surface of the liquid, tending to minimize the surface area. The surface tension of crude oil is typically between 20 and 30 dyne/cm. A surface tension of 20 dyne/cm indicates that the crude oil has a relatively high surface tension.

Based on the estimated values, the crude oil is likely to be paraffinic. Paraffinic crude oils are characterized by having a high API°, low Watson characterization factor, and low refractive index. They also tend to have a high surface tension.

Answer: John walks a total of 360 yards from school.

Step-by-step explanation:

Let's represent the total distance John walks from school as "x".

According to the problem, John has already walked 15% of the way, which can be written as:

0.15x

We also know that he has walked 54 yards so far, which means:

0.15x = 54

To find the total distance John walks from school, we can solve for "x" by dividing both sides of the equation by 0.15:

x = 54 ÷ 0.15

x = 360

Therefore, John walks a total of 360 yards from school.

The probability of x taking on a value between 75 to 90 is 0.25.

Given that x is a continuous random variable uniformly distributed between 65 and 85.To find the probability that x lies between 75 and 90, we need to find the area under the curve between the values 75 and 85, and add to that the area under the curve between 85 and 90.

The curve represents a rectangular shape, the height of which is the maximum probability. So, the height is given by the formula height of the curve = 1/ (b-a) = 1/ (85-65) = 1/20.Area under the curve between 75 and 85 is = (85-75) * (1/20) = (10/20) = 0.5Area under the curve between 85 and 90 is = (90-85) * (1/20) = (5/20) = 0.25.
