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:
112 ft³
Step-by-step explanation:
→ Length (l) = 7 ft
→ Breadth (b) = 4 ft
→ Height (h) = 4 ft
Formula we use,
→ l × b × h
The volume of cuboid will be,
→ l × b × h
→ 7 × 4 × 4
→ [ 112 ft³ ]
Hence, the volume is 112 ft³.
Answer:
B) x = e^x
Step-by-step explanation:
The graphs of y = e^x and y = x never intersect, so the solution set will be the empty (null) set for ...
x = e^x
_____
There is one intersection of y=x with cos(x) and with sin(x). There are an infinite number of solutions for x = tan(x).
Answer:
x = 10
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin60° = , then
sin60° = = = ( cross- multiply )
2x = 20 ( divide both sides by 2 )
x = 10
