Answer:
you can use a graphing calc
Step-by-step explanation:
Remember this: for a trig function of <span>y = A sin(Bx + C) + D
</span><span><span>amplitude is A
</span><span>period is <span>2π/B
</span></span><span>phase shift is −C/B
</span><span>vertical shift is <span>D
So the amplitude is -4, the period is </span></span></span>π and the phase shift is -3.14/2 = 1.57.
The answer is 7 because is the minimum
Answer:
Step-by-step explanation:
To find the slope, we use the formula:
M =
So, plug in our numbers. For reference:
-2 = x1 2 = y1
0 = x2 5 = y2
2 = x3 8 = y3
After plugging in:
Thus, your slope is .
Answer:
The steps to finding the upper and lower quartiles are given in the first choice.
1. Order the data from least to greatest. If you don't do this, the data is random.
2. Find the median - you will do this so that you can find the midpoint of the data set (half of of the data is smaller and half of the data is larger).
3. Find the lower quartile - this is the half of the lower half of numbers; think of it as breaking the lower half of the data into 2 sections.
4. Find the upper quartile - this is the half of the greater half of numbers; this will break the upper half of the data into 2 sections.
