Answer:
a is 622
Step-by-step explanation:
Answer:
[see below]
Step-by-step explanation:
A function's inputs do not repeat. This means that any point with the x-value not repeated with the other points can be added to ensure that it continues as a function.
In this scenario:
{x| x ≠ -7, 4, 0, -2}
A point that does not have the x-value of -7, 0, 4, and -2 could be added to the relation to ensure it continues to be a function.
Hope this helps.
Answer:
8 and 2.529
Step-by-step explanation:
The computation of the mean and the standard deviation is shown below:
Given that
Total number of questions is n = 40
The Probability of correct answer is p = 
So, the probability of the wrong answer is q = 
= 
Moreover, this is the binomial distribution
Based on the above information
The mean is
= 8
Now the variance is
= 
So, the standard deviation is
= 2.529
hence, the mean and the standard deviation is 8 and 2.529 respectively
Answer:
Greatest possible number of solutions of these set of equations are 2
Step-by-step explanation:
We have been given two functions in the question.
x² + y² = 9
9x + 2y = 16
We know that the equation of circle is given by:
(x - h)² + (y - k)² = r²
However, if (h, k) is equals to (0, 0), the equation of circle becomes:
x² + y² = r²
Which is similar to the fist equation
x² + y² = 3²
Hence first equation is a circle.
As the second equation is a linear equation, it is simply a line.
We know that a line passing through the circle can intersect it at only 2 points.
Where points of intersection between both circle and line shows the solution.
So.
There are 2 possible solution to this set of equations
