Answer : The number of markers in each pack will be, 8
Step-by-step explanation :
Let the number of markers in each pack be, x
The number of markers in 8 packs = 8x
Chelsea gives 10 markers to her brother and she has 54 markers left. So,
Total number of markers = 10 + 54 = 64
Now we have to determine the number of markers in each pack.
The equation will be:
Thus, the number of markers in each pack will be, 8

Step-by-step explanation:
y = 3.25x + 1.25
1.25 is y-intercept
3.25 is the slope of a graph.
If x = 0, then y = 1.25
(0, 1.25)
If x = 3, then y = 3.25(3) + 1.25 = 11
(3, 11)
Answer:
0.077
Step-by-step explanation:
From the table :
Number of students aged 31 - 35 = 60
Number of students over 35 = 26
Total number of students = total possible outcomes = 1123
Required outcome = (students aged 31 - 35) + over 35 = 60 + 26 = 86
Probability = required outcome / Total possible outcomes
Probability (at least 31) = 86 / 1123 = 0.0765
= 0.077 (3 decimal places)
