Answer:
D) 11/12
Step-by-step explanation:
From 1 to 12, 6 numbers are odd (1, 3, 5, 7, 9, and 11).
7 numbers are non-prime (1, 4, 6, 8, 9, 10, and 12).
2 numbers are both odd and non-prime (1 and 9).
Therefore, the probability is:
(6 + 7 − 2) / 12 = 11/12
Answer:
Step-by-step explanation:For the student to be considered for the tutoring or extension activities, his/her score must be 20 points lower or higher than the average.
The average is given as 105, that means:
Minimum score to be considered = 105 - 20 = 85
Maximum score to be considered = 105 + 20 = 125
If p represents the performance of a student, then this inequality will be represented as follows:
85 ≤ p ≤125
When there are no special grouping symbols, math problems are solved from left to right. Although there are other important rules about the order in which you do the operations (addition/subtraction/multiplication/division) in a math expression or equation, this lesson will focus on grouping symbols. The rest of the order of operations rules will be explained in the Determining Order of Operations lesson. To help prevent confusion as you learn how to use the grouping symbols, this lesson will only use addition and subtraction.

x+38+52+220=360
x+310=360
x=360-310
x=50
