Answer:

n = -13

Step-by-step explanation:

√10 - 3n = 7 ⇔

⇔ 10 - 3n = 49 ⇔ We need to remove the square root. Ex: √n = 2 ⇔ n = 2²

⇔ -3n = 49 - 10 ⇔
⇔ -3n = 39 ⇔
⇔ n = $\frac{39}{-3}$ = -13 (as -3 changes members, as it was multiplying, it now divides, conversion).

Answer:

Therefore, we conclude that the statement in (A) is incorrect.

Step-by-step explanation:

We have the following sentences:

A) If the probability of an event occurring is 1.5, then it is certain that event will occur.

B) If the probability of an event occurring is 0, then it is impossible for that event to occur.

We know that the range of probability of an event occurring is in the segment [0, 1]. In statement under (A), we have the probability that is equal to 1.5.

Therefore, we conclude that the statement in (A) is incorrect.
