The answer that you are looking for is d
Answer:
Step-by-step explanation:
1.) Get the equation in the form y = ax^2 + bx + c.
2.) Calculate -b / 2a. This is the x-coordinate of the vertex.
3.) To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y. This is the y-coordinate of the vertex.
1.) y = -x^2 - 10x + 24
2.) -(-10) / 2(-1) = -5
3.) y = -(-5)^2 - 10(-5) + 24
y = -25 + 50 + 24
y = 49
Yes, he is correct. Since.....
(−2)^4
=(−2)*(−2)*(−2)*(−2)
=(−2)^4
=16
May I please ask,Where is the Mathematic problem that I may solve. ;)
Answer:
P = number of adults who have shopped at least once on the internet / number sampled adults
Step-by-step explanation:
Step 1
Let X be the number sampled adults
Let Y be the number of adults who have shopped at least once on the internet.
Let P be the probability that a randomly selected adult has shopped on the Internet.
Step 2
P = number of adults who have shopped at least once on the internet / number sampled adults
P = Y/X
An example:
If X is 1000 adults and Y is 200 adults therefore P = 200/1000 = 0.2
One can therefore infer that approximately 0.2 of the population surfs the internet at least once in a week.
