Answer:

$198.75

Step-by-step explanation:

total amount spent = cost of groceries + cost of flowers

total cost of groceries = initial cost - coupon value

coupon value = 0.10 x 150 = $15

Total cost = $135

total cost of flowers = cost of flowers + tax value

tax value = 0.0625 x $60 = $3.75

total cost of flowers = $3.75 + $60 = $63.75

total amount spent = $135 + $63.75 = $198.75

For five-number summary for the distribution as Q1 is 39, it follows that around 75% of the states have cigarette taxes higher than 39 cents.

A list of numerical data is divided into three quarters by the values known as quartiles. The middle of the three quarters measures the distribution's center point and displays data that are close to it. Only half of the data set, which is below the median, is shown in the lower part of the quarters, while the upper half, which is above the median, is shown in the upper part. In all, the quartiles depict the distribution or dispersion of the data set.

When the data are sorted in ascending order, Q1, or the lower quartile, is the data point below which 25% of the data lie or above which 75% of the data lie. In other words, the lower quartile is greater than 25% of the data or less than 75% of the data.

As Q1 is 39, it follows that around 75% of the states have cigarette taxes higher than 39 cents.

ii) When the data are sorted in ascending order, the Q3 or upper quartile is the data point above which 25% of the data lie or below which 75% of the data lie. In other words, the data in the top quartile either make up more than 75% or less than 25% of the total data.

Q3 being 103 signifies that 25% of the states have cigarette taxes that are more than 103 cents.

Step-by-step explanation:

Jenna's method :

5(30 + 4) = 5(34) = 170

Mia’s method :

5(30 + 4) :

5(30) + 5(4)

150 + 20

= 170

With both methods, we will arrive at the same answer as justified in the workings above. However, Jenna's method gives a very simple approach and less complicated arithmetic by using the distributive property to overrode some multiplication process which Mia went through in her own calculation. Therefore, Jenna's method is less complicated and requires two simple steps at obtaining the final result.

Answer:

$1620

Step-by-step explanation:

The area of the lawn is a trapezoid.

Area of a trapezoid = \(\dfrac12(a+b)h\)

where a and b are the parallel sides (bases) and h is the height

Therefore,

\(area=\dfrac12(15+12) \times 10 = 135 \ m^2\)

If the price of sod is $12 per square metre, then

total cost = 135 x 12 = $1620

The margin of error can be calculated using the formula:
Margin of error = (upper limit of the confidence interval - lower limit of the confidence interval) / 2

In this case, a margin of error of 9.55 suggests that the sample mean is quite precise, since it's relatively close to the true population mean (which we know to be 52.90).

In this case, the lower limit of the confidence interval is 43.85 and the upper limit is 61.95.
Margin of error = (61.95 - 43.85) / 2
Margin of error = 9.55
Therefore, the margin of error is 9.55. This means that if the sample size were to be repeated, we would expect the sample mean to be within 9.55 units of the true population mean 95% of the time.
It's worth noting that the confidence interval provides a range of values within which we can be reasonably certain that the true population mean lies. The margin of error, on the other hand, gives us an indication of the precision of our estimate. However, if the margin of error were larger, this would indicate that our estimate is less precise and that we need a larger sample size to obtain a more accurate estimate of the population mean.

Answer: She would need 188 square inches of wrapping paper .

Step-by-step explanation:

Given:  The base of the box is a rectangle and has a length and width of 4in and 7in respectively.

The height of the box is 6 inches.

Surface area of cuboid = 2(lw+wh+hl) , where l = length , w = width and h = height.

Surface area of box = 2 (4 x 7+ 4 x 6 + 7 x 6)

= 2 (28+24+42)

= 2 (94)

= 188 square inches.

Hence,  she would need 188 square inches of wrapping paper .

1. P(X > 2) = 1 - P(X <= 2) = 1 - (0.8 + (0.2 * 0.8)) = 1 - 0.96 = 0.04 (4%).

2. P(X > 6) = (0.2)^6 = 0.000064 (0.0064%).

 1. The probability that you need to toss the coin more than two times is given by P(X > 2). Since the coin has a probability of 0.8 for heads (H) and 0.2 for tails (T), the probability of getting a head on the first toss is 0.8. However, if a head does not occur on the first toss, you need to continue tossing the coin until a head appears. The probability of getting tails on the first toss and heads on the second toss is (0.2 * 0.8). Thus, the probability of needing more than two tosses is 0.2 * 0.8 = 0.16 or 16%.

2. The probability of needing more than five or six tosses, P(X > 5 or X > 6), is the same as the probability of needing more than six tosses, P(X > 6). If you toss the coin more than six times, it means you have already tossed it more than five times. So, P(X > 5) is included in P(X > 6). Therefore, we can focus on calculating P(X > 6).

To find P(X > 6), we calculate the probability of not getting a head in the first six tosses. Since each toss is independent, the probability of getting tails on each toss is 0.2. The probability of not getting a head in six tosses is (0.2)^6 = 0.000064 or 0.0064%. Therefore, the probability of needing more than six tosses is approximately 0.0064% or very close to zero.

The exact values of the sine, cosine, and tangent of the angle 255° are -1/√2, 1/√2, and -1, respectively.

To find the exact values of the sine, cosine, and tangent of the angle 255°, we can use the identity that relates the trigonometric functions of an angle to the trigonometric functions of its complement.

By expressing 255° as the sum of 300° and -45°, we can determine the exact values of the trigonometric functions for the given angle.

We know that the sine, cosine, and tangent of an angle are periodic functions, repeating every 360 degrees. To find the exact values of the trigonometric functions for 255°, we can express it as the sum of 300° and -45°, where 300° is a multiple of 360°.

Since the sine, cosine, and tangent functions are odd or even functions, we can use the values of the trigonometric functions for 45° to determine the values for -45°.

For 45°:

sin(45°) = cos(45°) = 1/√2

tan(45°) = 1

Since cosine is an even function, cos(-45°) = cos(45°) = 1/√2.

Since sine is an odd function, sin(-45°) = -sin(45°) = -1/√2.

Using the definition of tangent as the ratio of sine to cosine, tan(-45°) = sin(-45°) / cos(-45°) = (-1/√2) / (1/√2) = -1.

Therefore, for the angle 255°:

sin(255°) = -1/√2

cos(255°) = 1/√2

tan(255°) = -1

The Solution using two methods are 323, .291, the correct option is B`.

Probability of an event is a measurement of how likely an event can occur as an outcome of a random experiment.

Probability ranges from 0 to 1, both inclusive. Events whose probability is closer to 0 are rarer to occur than those whose probabilities are closer to 1 (relatively).

When converted to percentage, we just need to multiply its decimal representation by 100. In percentage form, the probability ranges from 0% to 100%.

The correct option is option (b). The percent overall error rate for the given confusion matrix is approximately 37.5%.

In the confusion matrix, the diagonal elements represent the correct predictions, while the off-diagonal elements represent the incorrect predictions. The overall error rate is calculated by summing up the incorrect predictions and dividing it by the total number of predictions.

In this case, the total number of predictions is the sum of all the elements in the confusion matrix, which is 80 + 100 + 20 + 120 = 320.

The total number of incorrect predictions is the sum of the off-diagonal elements, which is 100 + 20 = 120.

The percent overall error rate is then calculated by dividing the total number of incorrect predictions by the total number of predictions and multiplying by 100:

(120 / 320) * 100 = 37.5%.

Therefore, the percent overall error rate is approximately 37.5%, which corresponds to option b.

16 percent markup is the new retail price over the manufacturer price.

Here,

A store sells candles.

Retail price will be 45% marked-up

A month later, store reduced the retail price of the candles by 20%.

We have to find the percent markup.

What is the percentage?

The percentage is the value per hundred.

Now,

Consider the manufacturer price = 100x

Retail price will be 45% marked-up

Hence,  100x+45% of 100x = 145x

Reduced retail price of the ladder after one month = 145x-145x*20/100

Reduced retail price of the ladder after one month = 116x

Percentage markup of the reduced retail price over the manufacturer price will be:

={(reduced retail price - manufacturer price)/manufacturer price} *100

=[ (116x-100x)/100x ] *100 = 16%

Hence, 16 percent markup is the new retail price over the manufacturer price.

To determine the rate of simple interest at which an amount grows to \(\displaystyle\sf \frac{5}{4}\) of the principal in 2.5 years, we can use the formula for simple interest:

\(\displaystyle\sf I= P\cdot R\cdot T\)

where:

\(\displaystyle\sf I\) is the interest earned,

\(\displaystyle\sf P\) is the principal amount,

\(\displaystyle\sf R\) is the rate of interest, and

\(\displaystyle\sf T\) is the time period.

Given that the amount after 2.5 years is \(\displaystyle\sf \frac{5}{4}\) of the principal, we can set up the equation:

\(\displaystyle\sf P+ I= P+\left(\frac{P\cdot R\cdot T}{100}\right) =\frac{5}{4}\cdot P\)

Simplifying the equation, we get:

\(\displaystyle\sf \frac{5P}{4} =\frac{P}{1} +\frac{P\cdot R\cdot T}{100}\)

Now, let's solve for the rate of interest, \(\displaystyle\sf R\). We can rearrange the equation as follows:

\(\displaystyle\sf \frac{5P}{4} -\frac{P}{1} =\frac{P\cdot R\cdot T}{100}\)

\(\displaystyle\sf \frac{5P-4P}{4} =\frac{P\cdot R\cdot T}{100}\)

\(\displaystyle\sf \frac{P}{4} =\frac{P\cdot R\cdot T}{100}\)

\(\displaystyle\sf 100P =4P\cdot R\cdot T\)

\(\displaystyle\sf R =\frac{100P}{4P\cdot T}\)

Simplifying further, we find:

\(\displaystyle\sf R =\frac{100}{4\cdot T}\)

Substituting the given time period of 2.5 years, we get:

\(\displaystyle\sf R =\frac{100}{4\cdot 2.5}\)

\(\displaystyle\sf R =\frac{100}{10}\)

\(\displaystyle\sf R =10\)

Therefore, the rate of simple interest required for the amount to grow to \(\displaystyle\sf \frac{5}{4}\) of the principal in 2.5 years is 10%.

In the given scenario, the cost function for producing chocolate bars is represented by C(q) = 1500 + 0.129q + 0.00592q^2, where q represents the quantity (number of chocolate bars) produced.

(a) The average cost function is found by dividing the total cost by the quantity produced. In this case, the average cost function is C(q)/q.

(b) The marginal cost function represents the change in cost when one additional unit is produced. It is obtained by taking the derivative of the cost function with respect to quantity, which in this case is C'(q) = 0.129 + 0.01184q.

(c) To compute the average cost and marginal cost when 700 chocolate bars have been produced, we substitute q = 700 into the respective functions.

(d) To find the actual cost of the 701st chocolate bar, we substitute q = 701 into the cost function C(q).

I will explain the steps to obtain the answers.

(a) The average cost function is given by C(q)/q. Substituting the cost function C(q) = 1500 + 0.129q + 0.00592q^2, we have (1500 + 0.129q + 0.00592q^2)/q.

(b) The marginal cost function is the derivative of the cost function with respect to quantity. Taking the derivative of C(q) = 1500 + 0.129q + 0.00592q^2 with respect to q, we get C'(q) = 0.129 + 0.01184q.

(c) To compute the average cost when 700 chocolate bars have been produced, we substitute q = 700 into the average cost function C(q)/q. Similarly, to find the marginal cost at 700 chocolate bars, we substitute q = 700 into the marginal cost function C'(q).

(d) To determine the actual cost of the 701st chocolate bar, we substitute q = 701 into the cost function C(q) = 1500 + 0.129q + 0.00592q^2 and calculate the value.

By following these steps, you will obtain the average cost, marginal cost, and the actual cost of the 701st chocolate bar.
