Answer:

a)- Given that a student is a 10th grader, there is a 14% chance he or she has a job.

Step-by-step explanation:

Option (a) is correct here because Relative frequency means the probability of occurrence or number of time-specific event occurs to the total event.

Option (b) is not correct because We already know that student is in 10th or 11th grade, after that we get to know about 14% chance.

Option (c) & (d) are clearly not possible.

Complete the statement to describe the expression (a+b+c)(d+e+f)
kherson [118]

Answer:

The given expression consists of 2 factors, and each factor contains 3 terms.

Step-by-step explanation:

Given the expression (a+b+c)(d+e+f)

Factors are parts of  expression that are connected by multiplication. we are multiplying  (a+b+c) and (d+e+f) so we said  (a+b+c) and (d+e+f) are factors of the expression.

Hence, there are 2 factors in given expression.

A mathematical expression contains numbers, variables and operators joined by addition, subtraction, multiplication, and division. The parts of the expression that are connected with addition and subtraction are known as terms.

In each factor (a+b+c) and (d+e+f) three terms are connected by addition. Hence, there are 3 terms in both the factors.
