The true statement "If x is a rational number and y is a rational number, then the sum of x and y is a rational number" is often

confused with the converse "If the sum of x and y is a rational number, then x is a rational number and y is a rational number." In this case, the converse is not always true. Which statement is false? A) If the sum of x and y is a rational number, then x must be a rational number. B) If x = 3.5 and y is a whole number, then the sum of x and y must be a rational number. Eliminate C) If x is an even integer and y is an odd integer, then the sum of x and y must be a rational number. D) If the sum of x and y is a rational number, then x may be a rational number or x may be an irrational number.

Answer:

D. if the sum of x and y is a rational number , then x may be a rational number or x may be an irrational number.

Step-by-step explanation:

the statement is false because the sum of a rational number and an irrational number is always equals to irrational number.

therefore, if the sum of x and y is a rational number , then x can only be a rational number.

for example:

if x = 5 ==== rational

if y = 2 ==== rational

x+y = 7 ==== rational

but, if

x = 1.333333......... ======irrational

y =  5                   =======rational

x+y = 6.3333333.... = irrational

Find P(A or B), if events A and B are overlapping.
BlackZzzverrR [31]
The answer is 7/9

P(A or B) = P(A) + P(B) - P(A and B)
P(A) = 11/18
P(B) = 5/18
<span>p(A and B) = 2/18
</span>P(A or B)  = 11/18 + 5/18 - 2/18 = (11 + 5 - 2)/18 = 14/18 = 7/9

Find the coordinates of P that partitions segment AB , where A (2,3) and B (14,9), so that AP:PB is a 1:2 ratio. Also, find the
Paladinen [302]

For Point P, you need to recognize that a 1:2 ratio means that AP will be 1/3 of AB and PB will be 2/3 of AB.

So you need to find the change in the x-values, 14-2 = 12, and then add 1/3 of that change to the x-value of A.

Then you need to find the change in the y-values, 9-3 = 6, and then add 1/3 of that change to the y-value of A.

For the bisector, that's another way to say you'll split AB into two even pieces.  For this, it's the same as what we just did, but you need to find 1/2 of the two respective changes (1/2 of the x-change and 1/2 the y-change).
