Answer:
1050 ways
Step-by-step explanation:
Total Number of red balls = 5
Total Number of blue balls = 5
Total Number of white balls = 7
Number of red balls selected = 3
Number of blue balls selected = 4
Number of red balls selected = 5
Using the multiplication and combination relation :
nCr * nCr * nCr
Red balls = 5C3
Blue balls = 5C4
White balls = 7C5
Using calculator:
5C3 * 5C4 * 7C5 = 10 * 5 * 21
(10 * 5 * 21) = 1050 ways
Answer:
Alternative D is correct
Step-by-step explanation:
For a relation to qualify as a function, a unique x value should be mapped to a unique y-value or unique x-values be mapped to the same y-value
Answer:
y = x - 9
Step-by-step explanation:
Keep in mind that the lines t and u are perpendicular, which implies that their slopes are negative reciprocals of one another. The negative reciprocal of the slope -1 of line t is +1.
Thus we need to find the equation of line u, knowing that the slope of this line is +1. Starting with the slope-intercept form y = mx + b, we find b:
y = mx + b becomes
-8 = (+1)(-1) + b, or -8 =-1 + b. Then b = -9, and the desired equation is
y = x - 9
Answer:
A is a subset of U.
Step-by-step explanation:
- A set is usually defined as a collection of elements. In this case, U={1,2,3,4,5} is a set that contains the elements 1,2,3,4, and 5. A subset is a <u>set that has been formed by elements of another set.</u> Any selection of the elements of the set {1,2,3,4,5} can be a subset of U. For example, {1,2} is a subset of U, because it is formed by elements of U.
- In this case, A={2,3} is another set, whose elements lie inside set U. Then. A is a subset of U.
