Will reward brainliest test the conditional statement and it’s converse to determine whether the following biconditional is true. a number is divisible by 10 if and only it is divisible by 5 a) it is false because at least one part of the biconditional is false b) it is true because both parts of the biconditional are true c) it is true because at least one part from the biconditional is true d) it is false because both parts of the biconditional are true

Option A. is the correct option.

Step-by-step explanation:

If a number is divisible by 5 it is not necessary that the number will be divisible by 10.

For example: 25 is the number divisible by 5 but not divisible by 10.

Or in other words a number divisible by 5 should be even to be divisible by 10.

So for the conditional statement : A number is divisible by 10 if and only if it is divisible by 5 will be false because any one out of these two statements is false. We know biconditional is true only when both the statements are true or false means both the statements should have same truth value.

Therefore Option A. is the correct option.

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
