The midpoint of AB is M (4,2). If the coordinates of A are ( 6,-4) what are the coordinates of B?
The coordinates of point B are calculated using the midpoint formula. Substituting given values for points A and M allows us to find B's coordinates, which are (2, 8).
Explanation:The midpoint of a line segment is calculated using the formula M=(x1 +x2)/2, (y1+y2)/2 where x1 and y1 are the coordinates of the first point and x2, y2 are the coordinates of the second point. Given that the coordinates of point A are (6,-4) and the coordinates of the midpoint M are (4, 2), we can set up the following equations to solve for the coordinates of point B (x2, y2): (6+x2)/2 = 4 and (-4+y2)/2 = 2. Solving for x2 and y2 gives us the coordinates of Point B: (2, 8).

Gina and Danny are playing an addition card game. In the card game, each player takes turns pulling two cards, one at a time, from a deck of cards. If the first card plus the second card is positive, the player keeps those cards. If the answer is zero or negative, the player loses those cards, and the cards go back in the deck.
There are only 10 cards in the deck, which have the following numbers:
(a) If a player gets a first card that is a positive number, what must the second card be in order for the player to keep the cards? Explain your reasoning.
(b) Gina pulls as her first card. What must her second card be in order for her to have a positive answer? List all correct answers and explain why or show your work.

The number of shirts Kelly has to choose from is 2, namely Redshirt and Pink shirt. Computed using the Cartesian Product of sets.
What is the Cartesian Product of two sets?The cartesian product of two sets A and B is a set containing ordered pairs (x, y), for every x ∈ A, and every y ∈ B.
How to solve the question?In the question, we are informed that Kelly is picking out an outfit to wear. The organized list below represents the sample space of all possible outfits.
Redshirt – Black pants
Redshirt – White pants
Pink shirt – Black pants
Pink shirt – White pants
We are asked to find the number of different color shirts Kelly has to choose from.
Assuming the sample space to be the Cartesian Product of the set of shirts and set of pants, we can write the set of shirts as the first element of every ordered pair to get:
Set of Shirts = {Redshirt, Redshirt, Pink Shirt, Pink Shirt}.
Removing the repeating terms, we get:
Set of Shirts = {Redshirt, Pink Shirt}.
Thus, the number of shirts Kelly has to choose from is 2, namely Redshirt and Pink shirt. Computed using the Cartesian Product of sets.

What is the mean,median,mode(s) an range if the numbers are 15,30,17,15,24,31,15
Hello There!
Mean: Average of numbers in a set of data.
STEP 1: Add the numbers together. In this case, we would add
15 + 30 + 17 + 15 + 24 + 31 + 15 = 147
STEP 2: Divide the sum by the number of digits you added. We would divide
147 "sum of numbers" by 7 "number of digits" and we would get an answer of
21.
The mean for the set of data is 21
Median: The middle number when all the numbers are listed in order.
To find the median, we would put the lowest number on the left and the biggest number on the right and continue to go from least top greatest.
-Least To Greatest-

In our set of numbers, we cross out one number from the left and the right each time until we come across one number in the middle. The number that is in the middle in 17.
The median for this set of data is 17
Mode: The number that occurs most often in a set of numbers.
15-15-15-17-24-30-31
Since the number 15 occurs three times, the mode for the set of data is 15.
The mode for this set of data is 15
Range: The difference between the highest and the lowest number.

Aubrey and Charlie are driving to a city that is 120 mi from their house. They have already traveled 20 mi, and they are driving at a constant rate of 50 mi/h. Complete the function that models the distance they drive as a function of time. Then complete a reasonable domain for this situation.
The function that models the distance they drive as a function of time is 120 = 20 + 50t
The required domain must be within the range of 0 and 2 i.e. 0≤t≤2
The formula for calculating distance travelled is expressed as:
Distance = Speed × time
Given the following
Total distance = 120 miles
Distance already travelled = 20milesIf they are trying at a constant rate of 50mi/hr, the distance travelled at the time "t", this period will be 50t.The required function that models the distance is expressed as;
120 = 20 + 50t
Hence the function that models the distance they drive as a function of time is 120 = 20 + 50t
To get a reasonable domain, we need to get the value of t as shown;
120 = 20 + 50t
120 - 20 = 50t
100 = 50t
t = 100/50
t = 2sec
Hence the required domain must be within the range of 0 and 2 i.e. 0≤t≤2

What is quadratic trinomial?It is a type of polynomial which contains three terms and the power of the polynomial is two.The general form of quadratic trinomial is [tex]ax^{2} +bx+c[/tex], where a, b, c are non zero real numbers and x is variableFor given example,
We have been given two quadratic trinomials (2x^2 - 5x + 7) and (4x^2 + 2x - 11).
If (2x^2 - 5x + 7) is subtracted from (4x^2 + 2x - 11),
= (4x^2 + 2x-11) - (2x^2 - 5x + 7)
= 4x^2 + 2x - 11 - 2x^2 + 5x - 7
= (4 - 2)x^2 + (2 + 5)x - (11 + 7)
= 2x^2 + 7x - 18
Therefore, the coefficient of x is 7.
