If you randomly pick a number from 1 to 25, what is the probability that the number will have “2” as one of the digits?

Step-by-step explanation:

In the interval , there are numbers total. The number appears as the ones digit for numbers in this interval: . The subset marks the interval of numbers in the set that has the number as the tens digit. There are numbers in this set. Since is counted twice, there are a total of numbers in the original interval that contain the number . Therefore, the probability a random selected number from the interval has the number in it is .

the answer would be c:   ax + b = ax + c

step-by-step explanation:

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
