Is the following conditional true or false? If it is true, explain why. If it is false, give a counterexample.

1 answer:

8 0

Based on the given statement above, the conditional would be FALSE. A conditional statement is an if-then statement which makes "if" as the hypothesis and "then" is the conclusion, but not all conditional statements are true. Based on the truth table, "snowing in Dallas' Texas" is considered true, but "then it is snowing in the United States" is False, which makes this statement FALSE.
The counterexample for this would be: IF IT IS SNOWING IN THE UNITED STATES, THEN IT IS SNOWING IN DALLAS, TEXAS.

Answer:

234

Step-by-step explanation:

We want to find the summation from n = 2 to n = 10 of the equation -4 + 5n.

We can use the summation formula:

$S=\frac{(a_1+a_n)*n}{2}$ , where a1 is the first term, $a_n$ is the last term, and n is the number of terms

Here, we can say the first term occurs when n = 2:

-4 + 5n

-4 + 5 * 2 = -4 + 10 = 6

The last term will be when n = 10:

-4 + 5n

-4 + 5 * 10 = -4 + 50 = 46

The number of terms is just 10 - 2 + 1 = 9 terms.

Substitute these in:

$S=\frac{(a_1+a_n)*n}{2}$

$S=\frac{(6+46)*9}{2}=\frac{468}{2} =234$

Thus, the answer is 234.
