If total sales including tax are $2739.45 , the portion that is the tax amount is $155.06. So, correct option is C.

To find the portion that is the tax amount, we need to first determine the portion of the total sales that is the cost of the item before taxes. To do this, we can use the fact that the sales tax is 6%, which means that the total sales including tax is 106% of the cost before taxes.

Thus, we can set up the equation:

total sales including tax = cost before taxes + tax amount

Or, in terms of percentages:

106% cost before taxes = cost before taxes + tax amount

Simplifying this equation, we get:

0.06 cost before taxes = tax amount

Now we can substitute the given information into this equation. If total sales including tax are $2739.45, then the cost before taxes is:

cost before taxes = total sales including tax / 1.06

cost before taxes = $2584.39

Finally, we can calculate the tax amount:

tax amount = 0.06 * $2584.39

tax amount = $155.06

Therefore, the answer is option C, $155.06.

The range is greater for the girls and the mean is greater for the girls. So, correct option is B.

A) The statement "The range is greater for the girls" is true. The range is the difference between the highest and the lowest values in a data set.

Looking at the line plots, the highest value for the boys is 10, and the lowest is 3, giving a range of 7 hours. The highest value for the girls is 9, and the lowest is 5, giving a range of 4 hours. Therefore, the range is greater for the boys.

B) The mean is the sum of all values divided by the total number of values. To calculate the mean for the boys, we add up all the hours and divide by 10, which gives us:

(3 + 6 + 7 + 7 + 8 + 8 + 8 + 8 + 9 + 10) / 10 = 7.4 hours

To calculate the mean for the girls, we add up all the hours and divide by 10, which gives us:

(5 + 6 + 6 + 6 + 7 + 7 + 7 + 8 + 8 + 9) / 10 = 7.1 hours

The measure of the angle m∠PQR is equal to 50° using the secant tangent angle formula. So option A is correct.

The secant tangent angle is the angle formed by a tangent and a secant that intersect outside of a circle. The measure of the secant tangent angle can be found using the following formula:

θ = 1/2 (arc EB - arc BD)

where arc EB and arc BD are the measures of the arcs intercepted by the secant and tangent, respectively.

From the question,

θ = m∠PQR

arc EB = 160°

arc BD = 60°

m∠PQR = 1/2(160° - 60°)

m∠PQR = 1/2 × 100°

m∠PQR = 50°

Therefore, the measure of the angle m∠PQR is equal to 50° using the secant tangent angle formula.

The set of data that contains two outliers is: 101, 135, 131, 99, 138, 136, 140. An outlier is a value that is significantly different from other values. In this set, both 99 and 138 are outliers because they are much lower and higher respectively than the other values. In the other sets, all values are relatively close to each other with no extreme deviations, thus they do not contain any outliers. Outliers can skew statistical analyses and should be removed or treated with caution.

Step-by-step explanation:

The set of data containing two outliers is the last one: 101, 135, 131, 99, 138, 136, 140. This can be determined by analyzing the range and distribution of the data. Two values, 99 and 140, are significantly different from the other values in the set and fall outside the typical range. These two extreme values are considered outliers and can impact the accuracy of any analysis or Scalculations based on the data.

The amount of $5000 is invested at 12% and $2000 is invested at 8%.

Let x be the amount invested at 8% and y be the amount invested at 12%. We know that the total amount invested is $7000, so we have:

x + y = 7000

We also know that the annual interest earned is $580. The amount of interest earned from the investment at 8% is 0.08x, and the amount of interest earned from the investment at 12% is 0.12y. So we have:

0.08x + 0.12y = 580

We now have two equations with two variables. We can solve for one variable in terms of the other in the first equation and substitute it into the second equation:

x = 7000 - y

0.08(7000 - y) + 0.12y = 580

560 - 0.08y + 0.12y = 580

The player can expect to win 1.67$ for each 3$ bet placed on the 5$ denomination.

In probability theory, the expected value or expectation is the value that a player would expect to receive on average if they repeated the same game many times under the same conditions.

To find the player's expectation, we need to use the formula:

Expectation = (Probability of Winning x Amount Won) - (Probability of Losing x Amount Lost)

Assuming that the player wins if the bet is successful, the probability of winning on a 5$ denomination bet is 1/3, since there are three possible outcomes (win, lose, or push). The probability of losing is 2/3, since the player will lose if the bet is unsuccessful or if the outcome is a push.

If the player bets 3$ on a 5$ denomination, there are two possible outcomes: they either win 5$ or lose 3$. Therefore, the player's expectation can be calculated as:

Expectation = (1/3 x 5$) - (2/3 x 3$) = 1.67$

The function y=4[tex](2)^{x}[/tex] is an exponential function with base 2 and vertical intercept at (0, 4).

To translate this function to the graph of y=4[tex](2)^{x}[/tex]-3, we need to shift the graph downwards by 3 units. This can be achieved by subtracting 3 from the original function as follows:

The length of GF is 4 cm minus half the length of side FH.

To do this, we can use the fact that point S is the midpoint of FH. This means that FS = 1/2 FH. Similarly, point T is the midpoint of GH, so TG = 1/2 GH. We can now use these equalities and the fact that SG = 4 cm and HT = 6 cm to set up an equation involving FH:

SG + GF + HT = ST + TG + FH

Substituting the given values and using the fact that TG = GH - TG = GH - 1/2 GH = 1/2 GH, we get:

4 cm + GF + 6 cm = 8 cm + 1/2 GH + FH

Simplifying and substituting FS = 1/2 FH and TG = 1/2 GH, we get:

10 cm + GF = 8 cm + FS + TG

GF = 8 cm + FS + TG - 10 cm

GF = 1/2 FH - 1/2 GH

Now, substituting the values we know, we get:

GF = 1/2 FH - 1/2 GH

GF = 1/2 (FS + SH) - 1/2 (GH)

GF = 1/2 (8 cm + SH) - 1/2 (GH)

GF = 1/2 (8 cm + FS) - 1/2 (GH)

GF = 1/2 (8 cm + 1/2 GH) - 1/2 (GH)

GF = 3 cm - 1/4 GH

We can now substitute TG = 1/2 GH and solve for GH:

TG = 1/2 GH

8 cm - FS = 1/2 GH

GH = 16 cm - 2 FS

Substituting this value into the expression for GF, we get:

GF = 3 cm - 1/4 (16 cm - 2 FS)

GF = 3 cm - 4 cm + 1/2 FS

GF = 1/2 FS - 1 cm

Finally, substituting FS = 8 cm - SH, we get:

Step-by-step explanation:

The rate of change of the area of the circle is decreasing at a rate of 97.636 cm^2/s when the radius is 44 cm.

Use the formula A=pi*r^2 to calculate the area of the circle when the radius is 44cm.

A=pi*r^2

A= 3.14159*(44 cm)^2

A= 6081.816 cm^2    

Use the formula A'=2pi*r*r' to calculate the rate of change of the area.

A'=2pi*r*r'

A'= 2*3.14159*44 cm*(7 cm/s)

A'= 97.636 cm^2/s

The area of a circle is calculated by the equation A=pi*r^2, where r is the radius of the circle. At the instant when the radius of the circle is 44 centimeters, the area is 6081.816 cm^2.

To calculate the rate of change of the area, we use the equation A'=2pi*r*r', where r' is the rate of change of the radius.

In this case, the radius of the circle is decreasing at a rate of 7 cm/s, so r'=7 cm/s. Plugging these values into the equation, we get A'=2*3.14159*44 cm*(7 cm/s), which equals 97.636 cm^2/s.

Therefore, the rate of change of the area of the circle is decreasing at a rate of 97.636 cm^2/s when the radius is 44 cm.

The statement "the product of two negative rational numbers is greater than either factor" is never true.

The statement "the product of two positive rational numbers is greater than either factor" is only sometimes true.

We have,

Part A:

The statement "the product of two negative rational numbers is greater than either factor" is never true.

This can be proved by considering a negative rational number, say -1/2, and multiplying it by a negative rational number that is greater in magnitude, say -2/3.

The product of these two negative rational numbers is 1/3, which is less than either factor.

Another example is -3/4 multiplied by -1/2 which results in 3/8, again less than either factor.

Part B:

The statement "the product of two positive rational numbers is greater than either factor" is only sometimes true.

For example, if we take 1/2 and 2/3, the product is 1/3 which is less than either factor.

Similarly, if we take 3/4 and 4/5, the product is 3/5 which is less than either factor.

Therefore, the statement is only sometimes true and not always true.
