Use photomath it’s more easy
If you're looking for the dashed line, here it is.
Answer:
Find the equation of the line perpendicular to x = 0 that passes through (-3,1)
Step-by-step explanation:
Using the equation, y - y1 = m(x - x1)
Since x = 0, the gradient, m = 0
Hence, y - 1 = 0
∴ y = 1
Question #1:
Just divide the side lengths to find the scale factor.
8 / 2 = 4.
Therefore the scale factor from MNO to M'N'O' is 4.
Question #2:
Rotation rule for 180 degree clockwise turn: (-x, -y)
Therefore your new points will be:
(5, 2), (5, 4), and (4, 4)
Answer:
(a) Bird
(b) 40%
(c) 7%
Step-by-step explanation:
The pie chart is attached below.
Approximate the portion of each type of pet as follows:
Fish ≈ 15%
Bird ≈ 33%
Dog ≈ 17%
Cat ≈ 23%
Other ≈ 7%
None ≈ 5%
(a)
The pet category "Bird" was selected by approximately one-third of
the community.
(b)
The proportion of the community that chose Cat was, 23%.
The proportion of the community that chose Dog was, 17%.
So, the proportion of the community that chose Cat or Dog was:
Cat% + Dog% = 23% + 17%
= 40%
(c)
The proportion of the community that chose "Other" was approximately 7%.
