Answer:
y = sin(x + 90°)
Step-by-step explanation:
cos 0 = 1
Since the point (0, 1) is on the graph, this graph is y = cos x, but that is not a choice, so this must be the graph of the sine function with a horizontal translation.
sin 0 = 0
sin 90° = 1
The translation is 90°.
Answer: y = sin(x + 90°)
Answer:
(0,1) (-1,1)
Step-by-step explanation:
Answer:
Graph 1 because if you just do the Y coordinate its much easier.
2.6 is the aswer.
Why?take the 2 number after the decimal the estimate
Answer:
a) 0.437; b) 0.291
Step-by-step explanation:
For part a,
There are 280+210 = 490 people that are over 18 years old. Out of these, 119+95 = 214 purchase 2 pairs of jeans annually. This is
214/490 ≈ 0.437
For part b,
There are 87+69+74+11 = 241 people who purchase 3 or more pairs of jeans. There were a total of 220+290+280+210 = 1000 people; this means there were 759 people tho purchased fewer than 3 pairs of jeans.
Out of these, 21+74+126 = 221 were in the age group 12-18. This gives us
221/759 ≈ 0.291
