Answer:
The correct option is (b)
Only II applies.
Step-by-step explanation:
Given
dy/dx = (x - 2)/(y - 2)
We want to check which of the given options is true.
I) produces a slope field with horizontal tangents at y = 2
This is not true
II) produces a slope field with vertical tangents at y = 2
This is true because putting y - 2 = 0, we have dy/dx ---> infinity.
Which is a slope field with vertical tangents at y - 2 = 0 or y = 2.
III) produces a slope field with columns of parallel segments
This is not true.
Probability that first student prefers mechanical pen = 0.30
P(first student does not and second student does) = 0.70 * 0.3 = 0.21)
P( selecting 2 or fweer) = 0.30+ 0.21) = 0.51 or 51%
Answer:
16y +14x
Step-by-step explanation:
2y+4y+=6y
5x+12x=17x
17x-4
For this case we must take into account the following conversions of units:
1lb = 16 oz
1 lb = 0.454 kg
Applying the conversion of units we have:
(0.800) * (1 / 0.454) * (16/1) = 28.1938326
Rounding off we have:
28.2 oz
Answer:
it needs 28.2 oz of flour
9 and 1/2 is a mixed number
