Answer:
6
Step-by-step explanation:
Given that the coordinate plane, three of the vertices of the rectangle are located at (-1.25, -0.25),
(-1.25, 0.25), and (1.25, 0.25)
The length L of the shape will be:
L = 0.25 - ( - 0.25 )
L = 0.25 + 0.25
L = 0.5
The width of the shape will be:
W = 1.25 - ( - 1.25)
W = 1.25 + 1.25
W = 2.5
Perimeter P = 2L + 2W
Substitute the Length and the width into the formula
P = 2(0.5) + 2(2.5)
P = 1 + 5
P = 6 metres
Therefore, the perimeter of the shape is 6 metres
Answer:
<u>*I need more detail* but if I guessed than the question is asking if the are equal triangles.</u>
Δabc=Δnlm
Step-by-step explanation:
Draw out both triangles and label them as described in the question. If one angle of the triangles are 80° and 50° than the other angle has to be measured as 50° because all the angles have to add up to 180°. And both triangles are said to have angles 80° and 50°. The length of ac and ab are equivalent because it is an isosceles triangle and same goes for Δnlm.
The mean absolute deviation of the number of books is 1.84
<h3>How to determine the mean absolute deviation?</h3>
The dot plot of the number of books is in the attached figure.
From the figure, we have:
x f
1 1
2 2
3 2
4 3
5 1
6 2
7 3
8 1
Start by calculating the mean using:
So, we have:
Evaluate the sum and products
Divide
The mean absolute deviation is then calculated as:
So, we have:
Evaluate the absolute difference
Evaluate the sum of products
Divide
Hence, the mean absolute deviation of the number of books is 1.84
