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.

Divide 2y2 + 8 by 2y + 4. Which expression represents the quotient and remainder?
Final answer:
To divide 2y² + 8 by 2y + 4, use long division to find the quotient and remainder.
Explanation:
To divide 2y² + 8 by 2y + 4, we can use long division. Here are the steps:
Divide the first term of the dividend by the first term of the divisor, which gives us y.
Multiply the entire divisor by y to get 2y² + 4y.
Subtract 2y² + 4y from the dividend 2y² + 8 to get 4.
Next, divide 4 by 2y + 4, which gives us 2.
Finally, we have a remainder of 0.
Therefore, the quotient is y + 2 and the remainder is 0.

what is the product? -9x(5-2x) 18x2 -45x -18x2-45x -18x-45 18-45x
Answer: A.
Step-by-step explanation:
The product of equation is 18x² - 45x.
What is linear equation?Each term in a linear equation has an exponent of 1, and when this algebraic equation is graphed, it always produces a straight line. It is called a "linear equation" for this reason.
Both linear equations with one variable and those with two variables exist.
Given equation -9x(5 - 2x)
product = -9x(5) - (-9x)(2x)
= -45x + 18x²
= 18x² - 45x
Hence the product is 18x² - 45x.

How do you complete the square of x^2-14x+33=0?
Final answer:
To complete the square for the equation x^2-14x+33=0, the constant 33 is moved to the other side, and the number needed to make the left side a perfect square trinomial, 49, is added to both sides, resulting in factoring and solving (x - 7)^2 = 16 to find x = 11 and x = 3.
Explanation:
To complete the square for the equation x^2-14x+33=0, you need to form a perfect square trinomial on the left side of the equation. First, you'll move the constant term to the right side:
x^2 - 14x = -33
Next, find the value that completes the square for the x-terms. This value is obtained by taking half of the coefficient of x (which is -14 in this case) and squaring it, giving us (-7)^2 = 49.
Add 49 to both sides of the equation:
x^2 - 14x + 49 = -33 + 49
x^2 - 14x + 49 = 16
Now, the left side of the equation is a perfect square trinomial, and can be factored into:
(x - 7)^2 = 16
To solve for x, take the square root of both sides:
x - 7 = [tex]\sqrt{16}[/tex]
x - 7 = +- 4
Finally, solve for x by adding 7 to both sides:
x = 7 +- 4
x = 11 or x = 3

The solution of the equation 3x-3= -18 is -5.
The algebraic expressions which are separated by an equal symbol in between them and with the same value is called is an equation
Example = 5x + 5 = 12
here, x is a variable and 5 and 12 are constants.
Given equation;
3x-3= -18
To find the value of x add 3 to both side, we get
3x = -18 +3
we get
3x = -15
divide both side by 3 we get
[tex]x = \dfrac{-15}{3}[/tex]
Convert in into the lowest form we get,
x = -5
