Step-by-step explanation:
This figure has 1 line of symmetry
Answer:
36
Step-by-step explanation:
Data provided in the question:
Standard error = 1.5 minutes ( ∵ number are repetitive 1.51.5 )
Standard deviation = 9 minutes ( ∵ number are repetitive 99 )
Now,
Standard error = ( Standard deviation ) ÷ √n
Here,
n is the sample size
Therefore,
on substituting the respective values, we get
1.5 = 9 ÷ √n
or
√n = 9 ÷ 1.5
or
√n = 6
or
n = 6² = 36
Answer:
If you look at the picture from my point of view it would be the top left box and the top middle box. Both have 10 boxes in them and you need three shaded in for half of that box, so if you have 10 boxes you will need 6 shaded in. Hope this helped.
