The height of a parallelogram is one-third its base. If the area of the parallelogram is 363 square inches, find its base and he
ight. (Draw a diagram.)
1 answer:
Answer:
Height = 11 inches
Base = 33 inches
Step-by-step explanation:
In this question, we are asked to find the height and base of a parallelogram given the area of the parallelogram.
From the question, we are told that height is 1/3 of base. This means that base is 3 times the height
So if we represent the height with variable h, then the base is 3h
Mathematically the area of a parallelogram can be calculated by the formula
A = bh
Thus ,
363 = h * 3h
3h^2 = 363
divide through by 3
h^2 = 121
h = √121
h = 11 inches
since b = 3h , then b = 3 * 11 = 33 inches

d) 0.70.
Step-by-step explanation:
High School Education = 187 men
High School Education and former smoker = 54 men
High School Education and moderate smoker =41 men
High School Education and heavy smoker = 36 men
The proportion of men with a high school education that are current or former smokers is given by the sum of former, moderate and heavy smokers with a high school education divided by the total number of men with a high school education sampled:
The proportion is 0.70.
Answer:
Step-by-step explanation:
Given :
Total students = 30
Students passed chemistry exam = 20
Students passed physics exam = 14
Students passed both exams = 6
To find: Venn diagram
Solution:
Total students = 30 i.e. U = 30
Students passed chemistry exam = 20
Students passed physics exam = 14
Students passed both exams = 6
Students passed only chemistry = 20-6 =14
Students passed only Physics = 14-6=6
So refer the attached figure for the Venn diagram
