The inequalities which the number lines represent are as follows;
While writing inequalities represented on a number line;
We must observe the direction of the line; and also observe the shading on the starting point of the line.
In case 1:
- The set of x values are represented as greater than 3;
- Therefore, the inequality is; x > 3
In case 2:
- The set of value are represented as less or equal to 2;
- Therefore, the inequality is; x <= 2
The number line to represent the street sign is as in the attached image;

Answer:
8 loads can be expected to occur during a 4-year period
Step-by-step explanation:
This question can be solved by a simple rule of three.
Suppose the mean time between occurrences of loads is 0.5 year.
This means that for 0.5 years, 1 occurence is expected.
(a) How many loads can be expected to occur during a 4-year period
0.5 years - 1 occurence
4 years - x occurrences
8 loads can be expected to occur during a 4-year period
Answer: 6.68%
Step-by-step explanation:
Given : The mean weekly income of electrical engineers in NJ is $1,200 with a standard deviation of $200.
i.e. and
Let x denotes the monthly income ( in dollars).
If normally distributed , then the probability of workers earn more than $1,500 :
Therefore , the percentages of workers earn more than $1,500 = 6.68%
