Step-by-step explanation:

Answer:

for the first and second questions the answers are

Field hockey players                   basketball players

mean:66                                      mean:72

mode:66                                      mode:72

median: 66                                  median:72

range:10                                      range:7

Step-by-step explanation:

1. For the Field Hockey Players

The mean height is 68 inches, the mode is 66 inches, the median is 66 inches, and the range is 15 inches.

2. For the Basketball Players:
The mean is approximately 67 inches, the median is 67 inches, the modes are 63 inches and 72 inches, and the range of the heights is 11 inches

3. All 10 basketball players are shorter than the tallest field hockey player.

3b. the overlapping heights are: 60 in., 64 in., 65 in., 66 in., 67 in., 68 in., 69 in., 72 in., and 74 in.

Field Hockey Players:

The data is sort as follows

60, 60, 64, 64, 65, 65, 65, 66, 66, 66, 66, 66, 66, 66, 67, 67, 67, 68, 68, 68, 68, 69, 69, 70, 72, 72, 72, 73, 75, 75.

Now let's calculate the measures of center and variability:

Mean (Average): Add up all the heights and divide by the total number of heights. We then round the answer to the nearest whole number.

Mean

= (60 + 60 + 64 + 64 + 65 + 65 + 65 + 66 + 66 + 66 + 66 + 66 + 66 + 66 + 67 + 67 + 67 + 68 + 68 + 68 + 68 + 69 + 69 + 70 + 72 + 72 + 72 + 73 + 75 + 75) / 30

= 2040 / 30

= 68 inches (rounded to the nearest whole number).

Mode: This is the height that occurs most frequently.

From the sorted list, we can see that 66 inches appears 8 times, which is more than any other height, so Mode = 66 inches.

Median: This is the middle height when all the heights are listed in ascending order. If there is an even number of heights, as in this case, the median is the average of the two middle heights.

Here, the 15th and 16th heights are both 66 inches, so Median = (66 + 66) / 2 = 66 inches.

Range: This is the difference between the tallest (maximum) and shortest (minimum) players.

Range = Maximum - Minimum = 75 inches - 60 inches = 15 inches.

So, for the field hockey players, the mean height is 68 inches, the mode is 66 inches, the median is 66 inches, and the range is 15 inches.

Basketball Player Heights

The data is sort as follows

63, 63, 64, 64, 66, 67, 68, 72, 72, 74.

Mean (Average): The mean is calculated by adding all the numbers together and then dividing by the number of numbers.

Mean

= (63 + 63 + 64 + 64 + 66 + 67 + 68 + 72 + 72 + 74) / 10

= 673 / 10

= 67.3 inches.

Median: The median is the middle number in a sorted, ascending list. If there are an even number of observations, the median is the average of the two middle numbers.

In our list, since we have 10 numbers, an even number, the median is the average of the 5th and 6th numbers.

Median = (66 + 67) / 2 = 66.5 inches.

Mode: The mode is the number that appears most frequently in a data set.

From our list, we can see that the numbers 63 and 72 both appear the most (2 times each). So, this data set has two modes: 63 inches and 72 inches.

The range is calculated by subtracting the smallest number in a set from the largest number.

In your data set, the smallest number (the minimum) is 63 inches and the largest number (the maximum) is 74 inches.

So, Range = Maximum - Minimum = 74 - 63 = 11 inches.

So, for this data set, the mean is approximately 67.3 inches, the median is 66.5 inches, the modes are 63 inches and 72 inches, and the range of the heights is 11 inches.

3. First, let's identify the tallest field hockey player. Considering all heights given for field hockey players, the tallest field hockey player is 75 inches.

Now, let's look at the basketball player heights. We have 10 basketball player heights in total: 68 in., 64 in., 63 in., 63 in., 72 in., 74 in., 60 in., 66 in., 65 in., and 69 in.

From this, we can see that all 10 basketball players are shorter than 75 inches. So, all 10 basketball players are shorter than the tallest field hockey player.

3b. The overlapping heights are those that appear in both basketball and field hockey teams. Looking at both sets, the overlapping heights are: 60 in., 64 in., 65 in., 66 in., 67 in., 68 in., 69 in., 72 in., and 74 in.

Step-by-step explanation:

To find The largest number of gift bags that can be packed, we need to find the greatest common divisor of these numbers.

Listing the prime factorization's for each number:

171 = 3 x 3 x 19

63 = 3 x 3 x 7

27 = 3 x 3 x 3

The weight of the contents in the container, to the nearest pound, is 117 pounds.

To calculate the weight of the contents, we first find the volume of the container, then multiply it by the weight per cubic foot.

Step 1: Calculate the volume of the container.

Volume = length × width × height

Volume = 13.5 ft × 10.5 ft × 2.5 ft

Volume = 354.375 cubic feet

Step 2: Calculate the weight of the contents.

Weight = Volume × Weight per cubic foot

Weight = 354.375 cubic feet × 0.33 pounds per cubic foot

Weight ≈ 116.8725 pounds

Rounded to the nearest pound, the weight of the contents is 117 pounds.

First, we find the volume of the container by multiplying its length, width, and height together. The formula for the volume of a rectangular prism is length × width × height. In this case, the dimensions are given as 13.5 feet for the length, 10.5 feet for the width, and 2.5 feet for the height.

Next, we multiply the volume of the container by the weight per cubic foot of the contents to find the total weight. The average weight per cubic foot is given as 0.33 pounds.

Finally, we round the calculated weight to the nearest pound to match the desired precision. In this case, the weight of the contents is rounded to 117 pounds.

Complete question:

A shipping container is in the shape of a right rectangular prism with a length of 13.5 feet, a width of 10.5 feet, and a height of 2.5 feet. The container is completely filled with contents that weigh, on average, 0.33 pound per cubic foot. What is the weight of the contents in the container, to the nearest pound?

The correct answer is: a. The population will fall below 1,200,000 around the year 2024.

To determine when the city's population will fall below 1,200,000, we need to use the formula for exponential decay:

[tex]P(t) = P_0 \cdot (1 - r)^t[/tex]

where:

-  P(t)  is the population at time  t .

-  P₀  is the initial population.

-  r  is the rate of decrease (expressed as a decimal).

-  t  is the number of years.

Given:

- Initial population,  P₀ = 1,405,233

- Rate of decrease,  r = 1.1% = 0.011

- Final population,  P(t) = 1,200,000

We need to find  t  such that:

[tex]1,200,000 = 1,405,233 \cdot (1 - 0.011)^t[/tex]

First, we divide both sides by 1,405,233:

[tex]\frac{1,200,000}{1,405,233} = (0.989)^t[/tex]

Next, we calculate the left-hand side:

[tex]\frac{1,200,000}{1,405,233} \approx 0.854[/tex]

So we have:

[tex]0.854 = (0.989)^t[/tex]

To solve for  t , we take the natural logarithm of both sides:

[tex]\ln(0.854) = \ln((0.989)^t)[/tex]

Using the properties of logarithms, we can bring down the exponent:

[tex]\ln(0.854) = t \cdot \ln(0.989)[/tex]

Now, solve for  t :

[tex]t = \frac{\ln(0.854)}{\ln(0.989)}[/tex]

Let's calculate this:

[tex]\ln(0.854) \approx -0.157 \\\\ \ln(0.989) \approx -0.011 \\\\ t = \frac{-0.157}{-0.011} \approx 14.27[/tex]

Since 14.27 years from 2010 is approximately in 2024:

[tex]2010 + 14.27 \approx 2024[/tex]

So the population will fall below 1,200,000 around the year 2024.

Step-by-step explanation:

Answer:

the answer is (D)

Step-by-step explanation:

The solution to the system of equations -4x + 3y = -2 and y = x - 1 is x = -1 and y = -2.

Given the system of equations in the question:

-4x + 3y = -2

y = x - 1

Solve the system of equations by substituting the expression for y from the second equation into the first equation:

-4x + 3y = -2

Plug in y = x - 1:

-4x + 3( x - 1 ) = -2

Simplifying, we get:

-4x + 3x - 3 = -2

Solve for x:

-x = -2 + 3

-x = 1

x = -1

Now, plug x = -1 into equation 2 and solve for y:

y = x - 1

y = -1 - 1

y = -2

Therefore, the solution is x = -1 and y = -2.

Answer:

A. Figure A

Step-by-step explanation:

We are given the figure WXYZ.

It is required to find the final figure after [tex]T_{2,7}D_{0,2}[/tex].

Now, [tex]D_{0,2}[/tex] means to dilate the figure by 2 units and [tex]T_{2,7}[/tex] means to translate it by 2 units to the left/right and seven units up/down.

As we have to apply [tex]T_{2,7}D_{0,2}[/tex] to the figure.

This means that first dilation is applied and then translation.

Since, the all the figures are dilated. We focus on the translations.

We can see that, only figure A is translated 2 units to the right and 7 units upwards.

So, option A is correct.
