Answer:
Which graph represents Y as a function of X ?
step-by-step explanation:
a. The graph of y = 2x represents a transformation of the parent function, y = x, which makes the graph twice as steep.
b. The graph of y = 2x represents a transformation of the parent function, y = x, which makes the graph half as steep.
c. The graph of y = x represents a transformation of the parent function, y = 2x, which makes the graph half as steep.
d. The graph of y = x represents a transformation of the parent function, y = 2x, which makes the graph twice as steep.
Answer:
no
Step-by-step explanation:
The best thing to do here is to put each of these into fractions, with the total (31) as the denominator.
14/31= silver
6/31= black
8/31= copper
3/31= various colours.
As you're looking for the keys that are silver or copper, you've got to add the two denominators together, which gives you 14+8= 22.
This cannot be simplified further, therefore, the probability of choosing either a silver or copper key is 22/31
Hope this helps :)
Answer:
1. 0^6=0 1^5=1 False
2. 7^3=7*7*7=343 7*3=21 False
3. 2^4=2*2*2*2=16 4^2=4*4=16 True
8*40 = 320 * 2 = $640 for the 2 workers
640/2000 = 0.32
labor cost is 32% of the revenue
