Answer:
Therefore Perimeter of Rectangle ABCD is 4 units
Step-by-step explanation:
Given:
ABCD is a Rectangle.
A(-6,-4),
B(-4,-4),
C(-4,-2), and
D (-6,-2).
To Find :
Perimeter of Rectangle = ?
Solution:
Perimeter of Rectangle is given as
Length = AB
Width = BC
Now By Distance Formula we have'
Substituting the values we get
Similarly
Therefore now
Length = AB = 2 unit
Width = BC = 2 unit
Substituting the values in Perimeter we get
Therefore Perimeter of Rectangle ABCD is 4 units
Since that is a right angle, it equals 90 degrees.
90 - 24 = 66
66 degrees...
I hope this helps..
Answer:
10.659 has 5 significant figures.
Step-by-step explanation:
Any number that is not 0 is a significant figure. There are 4 numbers that are not 0. Then, any 0 that is between two non-zero numbers is significant. The 0 is this number is between 1 and 6, so it is significant. Therefore, all the digits in this number are significant.
Answer:
Percentage of the students scored higher than 89% = 65.87%
Step-by-step explanation:
We need to find the percentage of students who scored higher than 89% given mean = 84 and standard deviation = 5.
We can find the percentage of students who scored higher than 89% by using z-score.
The formula for z-score is:
μ= mean = 84
σ=standard deviation = 5
x= random number = 89
Putting these values, we get
Now, we know that we need to find students who score greater than 89%
so P(X>89) or P(X>1),
finding value of z= 1 which can be easily found using z score tables.
By looking at table we get the value of z = 0.3413
Subtracting the value of z from 1 we get
Percentage of the students scored higher than 89% = 1-0.3413 = 0.6587 or 65.87%
