How do you graph a function with two X variables?
To graph a function with two variables, you need to plot the points that satisfy the function in a coordinate system.
For example, suppose you have a function f(x,y) = x^2 + y^2. To graph this function, you can choose a set of values for x and y that satisfy the function, and plot these points in the coordinate system.
For example, if you choose x = 1 and y = 2, then the point (1,2) satisfies the function because f(1,2) = 1^2 + 2^2 = 1 + 4 = 5. Similarly, if you choose x = -2 and y = 3, then the point (-2,3) satisfies the function because f(-2,3) = (-2)^2 + 3^2 = 4 + 9 = 13.
You can repeat this process for a range of values for x and y to plot more points in the coordinate system. As you plot more points, you will start to see a pattern emerge, which is the graph of the function.
Note that the graph of a function with two independent variables will be a surface in three-dimensional space, rather than a curve in two-dimensional space like the graph of a function with only one variable.

If the incomes in a certain larger population of college teachers have a normal distribution with mean of $60,000 and standard deviation of $5,000.the probability that their average salary exceeds $65,000 is 0.0228.
What is probability?Probability is the tendency or likelihood that an event will happen.
First step is to find the standard deviation
Standard deviation= $5,000/√4
Standard deviation= $5,000/2
Standard deviation= $2,500
Second step is to find the z -score
Z= 65,000 - 60,000/2500
Z= 5,000/2500
Z= 2

There are 11 counter in the bag. 8 of the counter are green. 3 of the counter are blue. Sid take at random two counter from the bag. Work out the probability that Sid take one counter of each colour
The probability that Sid takes one counter of each color is 0.5.
To find the probability that Sid takes one counter of each color, we need to know the total number of possible outcomes when Sid takes two counters from the bag. Since the order in which Sid takes the counters does not matter, there are two cases to consider:
Sid takes a green counter first and a blue counter second. There are 8 green counters and 3 blue counters, so there are a total of 8 * 3 = <<8*3=24>>24 outcomes in this case.
Sid takes a blue counter first and a green counter second. There are 3 blue counters and 8 green counters, so there are a total of 3 * 8 = <<3*8=24>>24 outcomes in this case.
In total, there are 24 + 24 = <<24+24=48>>48 outcomes when Sid takes two counters from the bag.
To find the probability that Sid takes one counter of each color, we divide the number of successful outcomes (24 in each case) by the total number of outcomes (48). This gives us a probability of 24/48 = 1/2 = 0.5.
