3 metres from one end to the third mark
Solution:
Total length of wood = 10 metre
Wood is marked into 10 equal length.
= 1 metre
Length of each marking = 1 metre
Number of metres from one end to third mark = 1 + 1 + 1 = 3 metre
The image of the marking is attached below.
Hence 3 metres from one end to the third mark.
31. diameter is twice radius. volume cylinder = πr²h
112π = π(7)²h
112π/(49π) = h
16/7 = h
32. volume of sphere is (4/3)πr³
if r = 1 the volume just = (4/3)π
both answers are C

Second answer is C. 12/13
Step-by-step explanation:
Just had the question.
Answer:
Step-by-step explanation:
Here a score is considered to be "unusual" if higher than 2 std. dev. from the mean OR lower than 2 std. dev. from the mean.
Thus, any score lower than (120 - 2[12]), or 96, or higher than (120 + 2[12] ), or 144, is considered to be "unusual."
