The center and shape of the distribution are respectively:

9.6

Skewed left

The center of a distribution is a found using a statistics such as mean, median, or mode, and then provides a single value that is representative of the data. The spread is one that describes how close the data values are to each other using the range or standard deviation. The shape is one that describes how the data looks on a graph.

From the bar graph, we see that the center of the distribution is at 9.6.

Similarly, we also see that it is skewed left because it is longer on the left side of its peak than on its right.

a) We need to add up the given numbers: = 11.

B. The number that should replace the question mark is 13.8.

a) To find the total for all three cards, we need to add up the given numbers: 6 + 2 + 3 = 11.

b) To find the number that should replace the question mark, we can use the information that the mean of the three numbers is 6.2. Since the mean is the sum of the numbers divided by the count, we can set up the equation:

(6 + 2 + 3 + x) / 4 = 6.2

Now we can solve for x:

(11 + x) / 4 = 6.2

11 + x = 24.8

x = 24.8 - 11

x = 13.8

Therefore, the number that should replace the question mark is 13.8.

(a) The margin of error at 95% confidence is approximately 1.68 ounces.

(b) The 95% confidence interval for the population mean weight of bags of sugar is approximately (1 lb 13.32 oz, 2 lb 8.68 oz).

(a) To compute the margin of error at 95% confidence, we need to determine the critical value corresponding to a 95% confidence level. Since the sample size is large (n = 121) and the population standard deviation is unknown, we can use the t-distribution.

With 120 degrees of freedom (121 - 1), the critical value at 95% confidence is approximately 1.98. The margin of error is then calculated as 1.98 * (standard deviation / square root of sample size), which gives us 1.98 * (7 oz / √121) ≈ 1.68 oz.

(b) To determine the 95% confidence interval for the population mean weight, we use the formula: sample mean ± margin of error. From part (a), the margin of error is approximately 1.68 ounces. The sample mean is 2 lb 3 oz, which can be converted to 35 ounces.

Thus, the 95% confidence interval is (35 oz - 1.68 oz, 35 oz + 1.68 oz), which simplifies to (33.32 oz, 36.68 oz). Converting back to pounds and ounces, we have approximately (1 lb 13.32 oz, 2 lb 8.68 oz) as the confidence interval for the population mean weight of bags of sugar.

The monthly payments for the same loan would be approximately $694.12.

To calculate the annual payment required to pay off a four-year, $27,000 loan at an interest rate of 9 percent EAR, we can use the formula for the present value of an ordinary annuity:

PV = PMT * (1 - (1 + r)^(-n)) / r

Where:

PV = Loan amount = $27,000

PMT = Annual payment

r = Interest rate per period = 9% = 0.09

n = Number of periods = 4

Plugging in these values into the formula, we can solve for PMT:

$27,000 = PMT * (1 - (1 + 0.09)^(-4)) / 0.09

Simplifying the equation, we have:

$27,000 = PMT * (1 - 0.708222) / 0.09

$27,000 = PMT * 0.291778 / 0.09

PMT = $27,000 * 0.09 / 0.291778

PMT ≈ $8,329.40 (annual payment)

To calculate the monthly payments for the same loan, we can divide the annual payment by 12:

Monthly payment = $8,329.40 / 12

Monthly payment ≈ $694.12

Therefore, the monthly payments for the same loan would be approximately $694.12.

The probability of drawing a shape that is red or a circle is 7/16 from the bag that contains 4 red circles, 3 blue circles, and 9 yellow triangles.

Number of red circles = 4

Number of blue circles = 3

Number of yellow triangles = 9

Total number of all items = 4+3+9 = 16

Thus, the total number of possible outcomes is 16.

The probability of getting a red shape  = 4/16

The probability of getting a circle   = 4/16 + 3/16 = 7/16

To calculate the probability of drawing an item circle or red color,

P(red or circle) = P(red) + P(circle) - P(red and circle)

P(red or circle) = 4/16 + 7/16 - 4/16

P(red or circle) = 7/16

Therefore, we can conclude that the probability of drawing a shape that is red or a circle is 7/16.

If the person who had forgot to pay had paid, the shopkeeper would have earned a 20% profit.

It is given that 5 customers bought 10, 15, 20, 25, and 30 toffees from a shop.

Therefore, the total number of toffees bought is

10 + 15 + 20 + 25 + 30 toffees

= 100 toffees.

Let the cost of one toffee be $x.

Hence the cost of 100 toffees is $100x

It is said that we need to consider the customer who had forgotten to pay has actually paid.

Therefore,

the shopkeeper has received money for 100 toffees.

Now, he makes a 20% profit on each toffee

Therefore the selling price of each toffee is-

20% of x  +  x

= 0.2x + x

= $1.2x

Hence for 100 toffees, he receives

$120x

Therefore, the profit made on those toffees is

$120x - $100x

$20x

Therefore profit percentage

= Profit/Cost Price  X  100

= 20x/100x  X 100

= 20%

Hence, he would have made a 20% profit.

Option C is correct.  Less than 100  is closest to total deaths resulting from ladder misuse each year.

According to the Consumer Product Safety Commission (CPSC), on average, approximately 300 people die each year in the United States from falls involving ladders.

However, not all of these deaths are due to ladder misuse. In fact, the number of deaths resulting specifically from ladder misuse is likely to be lower. It is estimated that a significant portion of ladder-related fatalities are caused by factors such as overreaching, misusing the ladder, or failing to follow proper safety guidelines.

To reduce the number of deaths and injuries resulting from ladder misuse, it is important to follow safety guidelines and to choose the right ladder for the job, taking into consideration factors such as height, weight, and stability.

Information is needed to evaluate the project's financial viability, considering factors such as the initial investment, expected cash flows, cost of capital, and project duration.

To calculate the year 1 operating cash flows (OCF), we need to subtract the year 1 costs from the year 1 revenues:

OCF = Year 1 Revenues - Year 1 Costs

OCF = $192,000 - $125,000

OCF = $67,000

To find the depreciation expense in year 3, we need to determine the depreciation method. The provided information is incomplete regarding the depreciation method, so we cannot calculate the depreciation expense in year 3 without knowing the specific method.

The change in Net Working Capital (NWC) in year 2 can be determined by multiplying the Net Working Capital percentage (given as a percentage of t+1 revenues) by the year 1 revenues and subtracting the result from the year 2 revenues:

Change in NWC = (Year 2 Revenues - Net Working Capital percentage * Year 1 Revenues) - Year 1 Revenues

Without the specific Net Working Capital percentage or Year 2 Revenues values, we cannot calculate the exact change in NWC in year 2.

The net cash flow from salvage (ATSV) is calculated by multiplying the Salvage Value percentage by the Initial Cost:

ATSV = Salvage Value percentage * Initial Cost

ATSV = 28% * $390,000

ATSV = $109,200

To calculate the project's NPV, we need the cash flows for each year, the cost of capital, and the project duration. Unfortunately, the information provided does not include the cash flows for each year, so we cannot calculate the project's NPV.

When the fire is steadily burning at a temperature of 600 degrees, the number of hours needed to run out is 30 hours.

From the information, the fire is steadily burning at a temperature of 600 degrees F and t was stated that the fire is no longer maintained, the temperature drops 20 F every half hour.

Therefore, the appropriate expression to solve the information will be:

Let the number if hours be h

600 - (20 × h) = 0

600 - 20h = 0

20h = 600

A $100 bill and a dime differ by a magnitude of 3.

Orders of magnitude can be used in order to define large quantities efficiently and more easily. A dime is a currency used in the US that is equivalent to 0.10 dollars.

So we can represent a dime as 10-¹ of a dollar

and we can write 100 dollars as 10² of a dollar.

Therefore the difference in the order of magnitude of 100 dollars and a dime would be the difference between the powers or exponents of those two quantities,
