Hello there.
<span>What is the value of the function y = 2x + 3 when x=−1
Answer: 5</span>
Answer:
Object point Q (x,y) ------------- image point Q'( -y,x)
Step-by-step explanation:
When a point A (x,y) is rotated 90 degrees counterclockwise about the origin the resulting image of the point is A'(-y,x)
This means first you alternate the positions of x and y coordinates then add a negative sign on the now new y coordinate.
Example a point B(2,3) rotated 90° counterclockwise about the origin will form an image B'(-3,2)
So if point Q (x,y) ------------- image Q'( -y,x)
Substitute real values for (x,y) coordinates to get correct answer.

D is the answer of your question
Answer:
So, the probability is P=0.27.
Step-by-step explanation:
We know that the mean of computer chips is 1 centimeter and a standard deviation of 0.1 centimeter. A random sample of 12 computer chips is taken.
We get:
We calculate:
We use a table for standard normal distribution, and we calculate the probability:
So, the probability is P=0.27.
