Y=2x+5 is greater than the rate of change of the function represented in the graph. To find this, first remember that rate of change is just slope. This means that you can easily find the slope of the already given function y=2x+5, which is just 2. Then you take two pairs from your table. I took -1,0 and 2,3. You then place those into the equation used to find slope, y2-y1 over x2-x1. 3-0 equals 3 and 2-(-1), which means 2+1, since you’re subtraction a negative number is also 3, meaning your slope or rate of change is 1. 1 is a smaller number than 2 and therefore the rate of change in the already given function is greater than that of the table. Hope this helps!

Help please, stuck on this one!

Answer:

AFCE = 30

P+Q = 11

Step-by-step explanation:

From the picture, you can see the figure can be decomposed into two identical large triangles with area 20, and 4 identical longer ones, that have to cover the remaining area 40, thus 10 each.

From that you can count the area.

Second puzzle is just trial and error.

One 8-oz serving each of coffee, energy drink, and soda contains 199 mg of caffeine. One serving of coffee has 11 mg more caffei
Mandarinka [93]

Answer:

soda = 35mg

coffee = 81mg

energy = 83mg

Step-by-step explanation:

coffee + energy + soda = 199

coffee = 11 + (2 * soda)

energy = (soda + coffee) - 33

(11 + (2 * soda)) + ((soda + (11 + (2 * soda))) - 33) + soda = 199

11 + 2s + s + 11 + 2s - 33 + s = 199

22 + 6s - 33 = 199

-11 + 6s = 199

6s = 210

s = 35

soda = 35mg

c  = 11 + 2s

c = 11 + 2(35)

c = 11 + 70

c = 81

coffee = 81mg

e = s + c - 33

e = (35) + (81) - 33

e = 116 - 33

e = 83

energy = 83mg

A null hypothesis is being tested. How does the confidence level affect the testing process?
xxTIMURxx [149]
<span>If you have a high confidence level, the chance of rejecting the null hypothesis is rare. If you have a low confidence level, the chance of of rejecting the null hypothesis is nonexistent. If you have a low confidence level, the chance of of rejecting the null hypothesis is rare. If you have a high confidence level, the chance of of rejecting the null hypothesis is high.</span>
