how to prove the median of a trapezoid is parallel to the bases and equal in length to the average of their lengths?
The median of a trapezoid is parallel to the bases and equal in length to the average of their lengths. This is due to the midpoint theorem and the definition of the average.
The median of a trapezoid is a line segment that connects the midpoints of the non-parallel sides of the trapezoid. By the definition of a trapezoid, the two parallel sides (the bases) are of equal length.To prove that the median of a trapezoid is parallel to the bases and equal in length to the average of their lengths, we will make use of the midpoint theorem and the definition of the average.First, let's look at the midpoint theorem: If two points are the midpoints of two sides of a trapezoid, then the line connecting them is parallel to the bases. Now, let's look at the definition of the average: The average of two numbers is equal to the sum of the numbers divided by two.Now, let's apply these two concepts to the median of a trapezoid. As stated above, the median of a trapezoid connects the midpoints of the non-parallel sides of the trapezoid. By the midpoint theorem, the line connecting the midpoints of the non-parallel sides of the trapezoid is parallel to the bases. Next, we need to prove that the median of a trapezoid is equal in length to the average of the lengths of the bases. We can do this by noting that the length of the median of a trapezoid is equal to the sum of the lengths of the bases divided by two. This is because the median line segment connects the midpoints of the bases, so the length of the median is equal to half the sum of the lengths of the bases.Therefore, we can conclude that the median of a trapezoid is parallel to the bases and equal in length to the average of their lengths.Learn more about median here

The statement that is not true is d. The slope of the regression line is the estimated value of y when x equals zero.
Which statement is not true?The slope of the regression line represents the change in the dependent variable (y) for a unit change in the independent variable (x).
It is not necessarily the estimated value of y when x equals zero. The value of y when x equals zero is given by the y-intercept, not the slope of the regression line.

PLS HELP
The average daily number of rotations for one of your tires is 16,815.
To calculate the average daily number of rotations for one of your tires, you need to divide the total distance you drive in a day (20 miles) by the circumference of your tire.
However, you need to make sure that the units are consistent.
Let's assume that the circumference of your tire from problem 1 is 6.28 feet.
Converting 20 miles to feet, we get:
20 miles = 20 x 5280 feet (1 mile = 5280 feet)
= 105,600 feet
Now, dividing 105,600 feet by the circumference of your tire, we get:
105,600 ft ÷ 6.28 ft/rotation = 16,815 rotations per day (rounded to the nearest whole number)
Therefore, the average daily number of rotations for one of your tires is 16,815.

in lixue’s garden, the green pepper plants grew 5 inches in 3 4 month. at this rate, how many feet can they grow in one month? (let 5 inches
It would grow by approximately 1.6668 inches to 1.2504 inches
In Lixue's garden, the green pepper plants grew 5 inches in 3-4 months. To find out how many feet they can grow in one month, we can use the given information.
Let's start by converting the inches to feet. Since there are 12 inches in a foot, we divide 5 inches by 12 to get the equivalent in feet: 5 inches ÷ 12 = 0.4167 feet (rounded to four decimal places).
Now, we need to determine how much they can grow in one month. Since the plants grew 0.4167 feet in 3-4 months, we divide this amount by the number of months to find their average monthly growth.
If we assume that the plants grew 0.4167 feet in 3 months, their monthly growth rate would be 0.4167 feet ÷ 3 months = 0.1389 feet per month (rounded to four decimal places).
If we assume that the plants grew 0.4167 feet in 4 months, their monthly growth rate would be 0.4167 feet ÷ 4 months = 0.1042 feet per month (rounded to four decimal places).
Therefore, based on the given information, the green pepper plants can grow approximately 0.1389 feet to 0.1042 feet in one month, depending on whether we consider a 3-month or 4-month timeframe.

Which point is located on the line represented by y = -3x + 4? A) (4,8) B) (4-8) C) (-4, 8) D) (-4,-8)
Answer:
B
Step-by-step explanation:
To determine which point lies on the line, substitute the x- coordinate of the point into the equation and if the value equals the y- coordinate of the point then it lies on the line.
A (4, 8)
y = - 3(4) + 4 = - 12 + 4 = - 8 ≠ 8 ← not on line
B (4, - 8 )
y = - 3(4) + 4 = - 12 + 4 = - 8 ← lies on line
C (- 4, 8 )
y = - 3(- 4) + 4 = 12 + 4 = 16 ≠ 8 ← not on line
D (- 4, - 8 )
y = - 3(- 4) + 4 = 12 + 4 = 16 ≠ - 8 ← not on line
The point lying on the line is (4, - 8 ) → B

How many gallons of a 50% antifreeze solution must be mixed with 80 gallons of 10% antifreeze to get a mixture that is 40% antifreeze?
240 gallons of a 50% antifreeze solution must be mixed with 80 gallons of 10% antifreeze to get a mixture that is 40% antifreeze.
Let's call the amount of 50% antifreeze solution that we want to mix with the 80 gallons of 10% antifreeze "x".
The total volume of the mixture after mixing x gallons of 50% antifreeze solution with 80 gallons of 10% antifreeze solution is given by (x + 80) gallons.
The concentration of antifreeze in the mixture is given by the weighted average of the antifreeze concentrations in the two solutions, where the weight for each solution is proportional to its volume:
(0.5x) + (0.1 * 80) = (0.4 * (x + 80))
Expanding and solving for x, we get:
0.5x + 8 = 0.4x + 32
0.1x = 24
x = 240
Therefore, we need to mix 240 gallons of 50% antifreeze solution with 80 gallons of 10% antifreeze solution to get a mixture that is 40% antifreeze.

Let f(t) = √² - 4. a) Find all values of t for which f(t) is a real number. te (-inf, 4]U[4, inf) Write this answer in interval notation. b) When f(t) = 4, te 2sqrt2, -2sqrt2 Write this answer in set notation, e.g. if t = A, B, C, then te{ A, B, C}. Write elements in ascending order. Note: You can earn partial credit on this problem.
a) The values of t for which f(t) is a real number are in the interval (-∞, 4] ∪ [4, ∞).
b) When f(t) = 4, the values of t are {-2√2, 2√2}.
In part a), we need to find the values of t for which the function f(t) is a real number. Since f(t) involves the square root of a quantity, the expression inside the square root must be non-negative to obtain real values. Therefore, we set 2 - 4t ≥ 0 and solve for t. Adding 4t to both sides gives 2 ≥ 4t, and dividing by 4 yields 1/2 ≥ t. This means that t must be less than or equal to 1/2. Hence, the interval notation for the values of t is (-∞, 4] ∪ [4, ∞), indicating that t can be any real number less than or equal to 4 or greater than 4.
In part b), we set f(t) equal to 4 and solve for t. The given equation is √2 - 4 = 4. Squaring both sides of the equation, we get 2 - 8√2t + 16t² = 16. Rearranging the terms, we have 16t² - 8√2t - 14 = 0. Applying the quadratic formula, t = (-b ± √(b² - 4ac)) / (2a), where a = 16, b = -8√2, and c = -14, we find two solutions: t = -2√2 and t = 2√2. Therefore, the set notation for the values of t is {-2√2, 2√2}, listed in ascending order.

To make a specific hair dye a hairstylist uses a ratio of one and 1/8 oz of red tone 3/4 oz of Gray tone and 5/8 oz of Brown tone if the stylist needs to make 20 oz of dye how much of each dye color is needed?
Answer: To make 20 oz of hair dye, the hairstylist needs to use 1 and 1/8 oz of red tone, 3/4 oz of gray tone and 5/8 oz of brown tone.
We can use proportionality to figure out how much of each dye color is needed.
Let's call the amount of red dye needed x, the amount of gray dye needed y and the amount of brown dye needed z.
According to the proportionality, we can write the following equation:
(1 + 1/8)x + (3/4)y + (5/8)z = 20
To find the amount of each dye color needed, we can solve this equation for x, y and z.
First, we can clear the fractions by multiplying all terms by 8:
(8 + 1)x + (6)y + (5)z = 160
Now we can solve for x:
9x + 6y + 5z = 160
x = (160 - 6y - 5z)/9
Similarly, we can solve for y and z:
y = (160 - 9x - 5z)/6
z = (160 - 9x - 6y)/5
Now we can substitute the desired amount of 20 oz into the equation and solve for x, y and z
