Given:
Line segment NY has endpoints N(-11, 5) and Y(3,-3).
To find:
The equation of the perpendicular bisector of NY.
Solution:
Midpoint point of NY is
Slope of lines NY is
Product of slopes of two perpendicular lines is -1. So,
The perpendicular bisector of NY passes through (-4,1) with slope 
. So, the equation of perpendicular bisector of NY is
Add 1 on both sides.
Therefore, the equation of perpendicular bisector of NY is .
The histogram is attached. Every column shows on the bottom the range of age and on the left the number of cars of that particular age.
In order to find the percentage of cars with less than 20 years or more than 40 years, you have to sum up the numbers of cars in the first two columns from left (age 0-9 and 10-19) and the last two (age 40-49 and 50-59).
The number of cars of requested age is: 3 + 2 + 0 + 3 = 8
Now, you need to calculate the total number of cars (sum the cars of every column): 3 + 2 + 8 + 4 + 0 + 3 = 20
Lastly, you need to calculate the ration between the cars of requested age and the total number of cars, and transform it into a percentage:
8 ÷ 20 = 0.40 = 40%
Therefore, your answer is
40%.
41 is the answer and me too
The kinetic energy of an object is the energy that it possesses due to its motion.
Answer:
option D
Yes, they are independent because P(A)×P(B)=P(A∩B)
Step-by-step explanation:
Given in the question,
p(A) = 3/5
p(B) = 4/7
p(A∩B) = 12/35
If two events A and B are independent then,
<h3>P(A n B)= P(A).P(B)</h3>
12/35 = 3/5 . 4/7
12/35 = 12/35
Hence, events A and B independent events
