The area of a parallelogram is the base times the height.
Area and base is given so we can use that to solve for the height:
72 = 6* h
h = 72/6
h = 12
The height is 12 units.
Answer: The probability of selecting at least one boy (the probability that the 2 students selected are not both girls) is 62/95 or 0.6526
Step-by-step explanation:
From the question, the students to be chosen must be selected from a group of eight boys and twelve girls. This means that the total number of students that these two students must be chosen from is:
8 + 12 = 20 students.
The next step would be to find the probability of selecting a boy:
= Total number of boys/Total number of students
= 8/20
We will also find the probability of selecting one girl from the group
= Total number of girls/Total number of students
= 12/20
To find the probability that the two selected students are not girls is the same as finding the probability of selecting at least one boy. To do this, we will first find the probability of choosing all girls and then subtract it from 1.
The probability of selecting or choosing 2 girls (without replacement)
(12/20) × (11/19)
= 132/380
= 33/95
Then, the probability of selecting at least one boy (the probability that the students chosen are not both girls)
= 1 - (33/95)
= (95/95) - (33/95)
= 62/95 or 0.6526
The answer is I think option B

A) Yes; AA Similarity
Step-by-step explanation:
Yes; AA Similarity
Answer:
136
Step-by-step explanation:
as you know that discriminant of a quadratic equation is
D= b² - 4ac
here, according to the give equation
x² + 10x -7 -2= 0
x²+ 10x -9 = 0
b= 10 , c= -9 and a= 1
by putting all these values in D.
you can get the value of discriminant which is 136.
