Answer:
The prevalence of serious defects in this population at the time of birth is 10%.
Step-by-step explanation:
The prevalence of serious defects is the number of infants that were born with seriours birth defects divided by the total number of infants born.
In this problem, we have that:
There were 1000 newborn infants.
100 infants were born with serious birth defects.
Calculate the prevalence of serious defects in this population at the time of birth.
This is:
The prevalence of serious defects in this population at the time of birth is 10%.
J'(2,2) , K'(6,2), L'(6,4) and M'(2,4)
<u>Explanation:</u>
Given:
The coordinates of the rectangle are:
J(3, 3), K(9, 3), L(9, 6), and M(3, 6)
The scale factor is 2/3
New coordinates = ?
Multiplying the coordinates by 2/3 to find the vertices of the image
The vertices of the image are:
J'(2,2) , K'(6,2), L'(6,4) and M'(2,4)
