2x+3. that is the answer because 2 and a number is 2x and 3 more than that would be adding 3
Answer:
A reflection is a transformation representing a flip of a figure. Figures may be reflected in a point, a line, or a plane. When reflecting a figure in a line or in a point, the image is congruent to the preimage. A reflection maps every point of a figure to an image across a fixed line.
Step-by-step explanation:
Answer:

And the z score for 0.4 is

And then the probability desired would be:

Step-by-step explanation:
The normal approximation for this case is satisfied since the value for p is near to 0.5 and the sample size is large enough, and we have:


For this case we can assume that the population proportion have the following distribution
Where:


And we want to find this probability:

And we can use the z score formula given by:

And the z score for 0.4 is

And then the probability desired would be:

Answer:
5x²-7x+2
step by step explanation:
(f•g)(x) = f(x)•g(x)
(x-1)•(5x-2)
x×5x-2x-5x-1×(-2)
5x²-2x-5x+2
=5x²-7x+2
