Answer:
Step-by-step explanation:
What is the equation?
You need to replace all A with 3 and all c with 12. If I had the equation, I'd be glad to help further.
You divide -16 by 76 and then mutiply your answer by the number you got
To find the answer, we can use expansion to turn the fraction’s denominator to be the same:
1/2
= 1×5 / 2×5
=5/10
We can then proceed to find the answer:
7/10 - 5/10
= 2/10
= 1/5
Therefore the answer is 1/5.
Hope it helps!
Solution :
It is given that a psychologist wants to determine the difficulty of the task influences on the estimate of how long people spend working on it.
Now we have to describe a experiment by using a completely randomized design and learn the effect of the difficulty on the estimated time is by randomly assigning 15 students to a Group 1 of easy mazes and other 15 students to the second group 2 of hard mazes. And then we compare the time estimates of the two groups.
Answer:
C
Step-by-step explanation:
We want to determine the vertex of the quadratic equation:
Recall that the vertex is given by the formulas:
In this case, <em>a</em> = -1, <em>b</em> = 2, and <em>c</em> = 1.
Determine the <em>x-</em>coordinate of the vertex:
To determine the <em>y-</em>coordinate, evaluate the function at <em>x</em> = 1:
In conclusion, the vertex of the quadratic equation is (1, 2).
Hence, our answer is C.
