Answer:
The correct option is 1 and 4 are correct.
Step-by-step explanation:
The dilation is the enlargement and comparison of a figure according to the scale factor from the given center of dilation.
The rule DO,2(x,y)(2x,2y) express the dilation with factor 2 and the center of dilation is origin. It shows the enlargement of the triangle. The sides of image is twice of the preimage.
In dilation the corresponding angles remains same and the corresponding sides are equal.
Therefore option 1 and 4 are correct.
Answer:
The answer is below
Step-by-step explanation:
a) Given that the number of sample (n) = 300, therefore since n > 30, the distribution of the sample means is going to be normally distributed.
b) The mean of the distribution of sample means (also known as the Expected value of M) is equal to the population mean μ.
c) The standard deviation of the distribution of sample means is called the Standard Error of M, it is given by:
