Answer: 25

Step-by-step explanation:

To figure out the mystery number, the biggest clue we have is the fact that the number is a double digit and the 2 integers add up to 7. We can list out the possible ways to get a sum of 7. Then we can see which is the mystery number.

0+7

1+6

2+5

3+4

With these pairs, we can automatically eliminate 0+7 because 70 is greater than 30. We can also eliminate 3+4 because 34 is even, not odd. When you flip it to 4+3, it is odd, but it is greater than 30. We can also eliminate 1+6 because 16 is even and 61 is greater than 30. Our answer is 25. 2+5=7 and 25 is odd that is less than 30.

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.

Let's find the value of x

Since the sum of internal angles of a triangle is 180°

therefore,

$\hookrightarrow \: (2x - 2) \degree + (x + 5) \degree + 90 \degree = 180 \degree$
