Answer: Inverse Operation
Step-by-step explanation:
Answer:
the answer for this problem is x^2+2x-15
Step-by-step explanation:
(x+5)(x-3)
x(x-3)+5(x-3)
x^2-3x+5(x-3)
x^2-3x+5x-15
=x^2+2x-15
I believe the answer would be (-1, 2) and (3,-3). Since the coordinates are reflected over the y axis, y is going to remain the same.
Answer:
Normal (12, 0.20)
Step-by-step explanation:
Given that a population of cats has a population mean of
Also given that the distribution of weights of these cats is fairly symmetrical.
Since sample size is large and a random sample of 100 cats are drawn from this population, we find that
the mean of the sample would follow a normal distribution with mean =population mean and std deviation = population std dev/sqrt n
i.e. Sampling distribution of X would be normal with
mean = 12 pounds
and std deviation =
