Answer:

0.61

Step-by-step explanation:

Pr (female) =  total number of females(n')/Total number of students(n)

Where P(female) = probability of selectinga female

Pr(female) = n'/n................. Equation 1

Given: n = 44 students, n' = 15+12 = 27 females

Substitute into equation 1

Pr(female) = 27/44

Pr(female) = 0.61.

Hence the probability of selecting a female is 0.61

0.2 (20x + 10) = -42
Finger [1]

Answer:

x = -11

Step-by-step explanation:

0.2(20x + 10) = -42

4x + 2 = -42                    Distribute 0.2 to the numbers in the paranthesis

4x = -44                          Add 2 to both sides

x = -11                              Divide 4 from both sides
