Answer:
The correct option is;
(x, y) → (215·x, 215·y)
Step-by-step explanation:
An enlargement is a form of transformation involving an alteration of the size of the shape. When a shape is to be enlarged, the center of the shape is noted and the enlargement of the dimensions of the shape from that center is by multiplication of each point by the factor of the enlargement or the scale factor.
Therefore, based on the requirement for enlargement, and given the dimension of the point from the center as (x, y) the enlargement then is (215·x, 215·y), where 215 is the scale factor.
Answer:
A. (x, y) → (215x, 215y)
Step-by-step explanation:
Enlargement of a figure is the process of increasing the size of a given figure by the use of a scale. It requires the use of a scale factor that is greater than 1 to form an image. This is called dilation in transformation.
Transformation is the process of manipulating the size or orientation of a figure. To enlarge a shape, a center of enlargement is required.
Thus, the rule that signifies enlargement of a figure is ;
(x, y) → (215x, 215y)
This implies multiplying the initial coordinate x and y by a factor of 215 to produce a required size of an image.

The times of all 15 year old who run a certain race are approximately normally distributed with a given mean Mu = 18 sec and standard deviation Sigma = 1. 2 sec. What percentage of the runners have times less than 14. 4 sec?.
Answer:
A. 0.15%
Step-by-step explanation:
The times of all 15 year old who run a certain race are approximately normally distributed with a given mean as 18 sec and standard deviation as 1.2 sec.
We know that,
