What is the total cost of a $136 radio that has a 25% discount and sales tax is 5%?
PLEASE HELPPP

Answer:

B

Step-by-step explanation:

Absolute value means the ending product must be positive

2 - 3 = -1

Because it is absolute, the answer is actual positive 1

The correct option is B,  II. only.

Given to us,

I. In the effective rate formula, n is equal to one.

Effective interest rate formula,

\(r = (1 + \dfrac{i}{n} )^n - 1.\)

where,

r is the effective interest rate,

i is the stated interest rate,

n is the number of compounding periods per year.

According to the question the compounding periods per year is not given to us. Also, loans are taken for a longer period of time.

Thus, we can conclude that statement is false.

II. The nominal rate is 7. 918%.

nominal rate = real interest rate + inflation rate,

but as it is not mentioned in the question about the inflation rate. the statement is true to us. Assuming the inflation rate is 0%.

Thus, we can conclude that statement is true.

III. The Federal Funds Rate is static.

This statement is false, as the no information is given about this statement also this can not be concluded through assumption.

Thus, we can conclude that statement is false.

Hence, The correct option is B,  II. only.

Answer:  There are $26$ choices for the first letter, $26$ for the second, and $26$ for the third. The last letter is determined by the first letter. Thus, there are $26^3 = \boxed{17576}$ such combinations.

Step-by-step explanation:

This means that picking a four-letter word that follows this rule is just like picking any 3 letter word (pick a 3 letter word and then add a "copy" of the first letter as a fourth letter)

so there's a total of 263 =17,576 combinations- 26 options for the first letter, 26 options for the second letter, and 26 options for the third letter.

The length of the side a is 24cm given that angle ∠A is 150°, angle ∠B is 12° and side b is 10 cm in a triangle ΔABC. This can be obtained by laws of sine.

When the triangles are not right angled we use laws of sine and cosine,

Laws of sine states that,

In a triangle ΔABC,

⇒ \(\frac{sinA}{a} =\frac{sinB}{b} =\frac{sinC}{c}\)

∠A, ∠B, ∠C are the three angles of the triangle ΔABC, a is the side opposite to the angle ∠A, b is the side opposite to the angle ∠B, c is the side opposite to the angle ∠C

Here in the question it is given that,

In a triangle ΔABC

We have find the length of the side a.

By using the laws of sine we can write that,

⇒ \(\frac{sinA}{a}= \frac{sinB}{b}\)

⇒ \(\frac{sin150^{0} }{a}= \frac{sin12^{0} }{10}\)

⇒ a = sin 150° × 10/sin 12°

⇒ a = 24 cm

Hence the length of the side a is 24cm given that angle ∠A is 150°, angle ∠B is 12° and side b is 10 cm in a triangle ΔABC.

The cost of Comcast's 560 obsolete cable boxes in ending inventory is $12,796.

Hi, I understand that you need help calculating the cost of Comcast's obsolete cable boxes using the provided inventory and purchase information. To do this, we'll follow these steps:

1. Identify the number of obsolete boxes: 560.
2. Calculate the total number of boxes in inventory.
3. Determine the weighted average cost per box.
4. Multiply the number of obsolete boxes by the weighted average cost per box.

Step 1: We already know that there are 560 obsolete boxes in ending inventory.

Step 2: Calculate the total number of boxes in inventory.
Beginning inventory: 16,100 boxes
March 1: 7,100 boxes
June 1: 3,100 boxes
September 1: 1,800 boxes
December 1: 1,000 boxes
Total inventory: 29,100 boxes

Step 3: Determine the weighted average cost per box.
Total cost of inventory: $665,100
Total number of boxes: 29,100
Weighted average cost per box: $665,100 / 29,100 = $22.85 (rounded to two decimal places)

Step 4: Multiply the number of obsolete boxes by the weighted average cost per box.
Number of obsolete boxes: 560
Weighted average cost per box: $22.85
Cost of obsolete boxes: 560 * $22.85 = $12,796

So, the cost of Comcast's 560 obsolete cable boxes in ending inventory is $12,796.

The points x ≤ 1 2/3 and x<-3/4 has plotted in the number line

A number line is a visual representation of the real number system. It is a straight line on which numbers are marked at equal intervals, with zero in the center and positive numbers to the right of zero and negative numbers to the left of zero

The line represents the set of all real numbers, with negative numbers to the left of zero and positive numbers to the right. The point marked with a circle (o) represents the value of x that satisfies both conditions, which is x ≤ 1 2/3 and x < -3/4. Since -3/4 is less than 1 2/3, any value of x that satisfies x ≤ 1 2/3 must also satisfy x < -3/4, so the two conditions are equivalent in this case.

The probability that the selected student has at least one of the two types of cards is at least 0.2.

To find the probability that the selected student has at least one of the two types of cards, we can use the principle of inclusion-exclusion.

Let's define:

P(A) = probability of having the first type of card,

P(B) = probability of having the second type of card.

The formula for the probability of the union of two events, A and B, is given by:

P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

Given that P(A ∩ B) = 0.2, we can rewrite the formula as:

P(A ∪ B) = P(A) + P(B) - 0.2

Since we want to find the probability of having at least one of the two types of cards, we are interested in P(A ∪ B). Therefore, the probability is at least 0.2, as stated.

This means that even if the probability of having only one of the two types of cards is zero, the probability of having at least one of them is still 0.2 or higher.

The degrees of freedom for an independent t-test when n1 = 16 and n2 = 12 are 26.

Given,

n1 = 16

n2 = 12

Here,

An independent t-test, often known as a two-sample t-test, compares the means of two unrelated groups to see whether they are significantly different from each other. The t-test is an essential method that can help you determine whether or not a certain hypothesis is true, regardless of whether or not it is accurate.

Degree of freedom for independent t test: DF = (n1 + n2) - 2

DF = (16 + 12) - 2

DF = 26

Net present value is a measure of profitability. The NPV of an investment is the net cash inflow received over the project's life, less the initial cash outflow, adjusted for the time value of money.

A higher NPV means the project is more lucrative. The profitability index measures the benefit-cost ratio of a project and is calculated by dividing the present value of future cash flows by the initial cash outflow. A profitability index greater than one indicates that the project will be profitable, whereas a profitability index less than one indicates that the project will not be profitable.

To find the measure of angle D in triangle DEF, we can use the fact that the angles in a triangle add up to 180 degrees. Given that angle F is 43 degrees, we can subtract this angle from 180 to find the combined measure of angles D and E: 180 - 43 = 137 degrees.

Now, let's focus on angle D. We are given the lengths of two sides of the triangle, d and f. Using the law of cosines, we can find the measure of angle D. The law of cosines states that in a triangle with sides a, b, and c, and opposite angles A, B, and C respectively, the following equation holds true c^2 = a^2 + b^2 - 2ab * cos(C)

In our case, side d is opposite to angle D, and side f is opposite to angle F. Let's substitute the values into the equation: d^2 = f^2 + 16^2 - 2 * f * 16 * cos(D) Simplifying further, we get: d^2 = f^2 + 256 - 32f * cos(D) Now we can substitute the known values into the equation: 16^2 = 24^2 + 256 - 32 * 24 * cos(D). To find the measure of angle D, we can use the inverse cosine function (also known as the arccosine function) to find the angle whose cosine is 0.75.  Therefore, the measure of angle D in triangle DEF is approximately 41.4 degrees.
