Answer:
The probability is 0.95
Step-by-step explanation:
In this question, we are interested in calculating the probability that a randomly selected student of the university recycles at least some of the times
Mathematically, the probability that student recycles at least some of time = 1 - probability that the student never recycles all the time
From the question, the probability that the student never recycles all the time = 0.05
Substituting this into the equation given above;
Probability that a randomly selected student at the university recycles at least some of the time = 1-0.05 = 0.95
Answer:
Step-by-step explanation:
The answer is 1.3
Since triangle ABC is similar to triangle DEF then the ratio of the corresponding sides is constant.
The ratio of the corresponding lengths is referred to as the linear scale factor.
Considering the heights of the two triangles;
L.S.F = 14/6
= 7/3
The ratio in area (A.S.F) is given by (L.S.F)²
Therefore, A.S.F = (7/3)² = 49/9
Thus te ratio of the area of triangle ABC to DEF is 49:9
