The solution of the inequality is x < -9
<h3>How to solve the inequality for x?</h3>
The inequality expression is given as:
-11 < -18- 7/9x
Add 18 to both sides of the inequality
18 - 11 <- 7/9x
Evaluate the difference
7 <- 7/9x
Multiply both sides by -9/7
-9 < x
Rewrite as:
x < -9
Hence, the solution of the inequality is x < -9

Answer:
d) P(D|E)
Step-by-step explanation:
E = person exercises
D = person on a diet
Given the expression :
Of all the people who exercise, the probability that a randomly chosen person is on a diet.
This simply refers to a conditional probability whereby the subset from which the probability that a randomly chosen person is on diet is to be calculated is the subset of those who exercise.
In statistical parlance, the statement is expressed as ; the probability of A given B = P(A|B)
In this scenario, we say; the probability that a randomly chosen person is on a diet Given that the person exercise ; P(D|E)
Hence, the answer is D.

Answer: The first one, the last one,
Step-by-step explanation:
“Line graphs are useful in that they show data variables and trends very clearly and can help to make predictions about the results of data not yet recorded. They can also be used to display several dependent variables against one independent variable.”
“With a line graph, it is fairly easy to make predictions because line graphs show changes over a period of time. You can look at past performance in a line graph and make a prediction about future performance.”
