Answer:
a) 12/91
b) about 67 times; (66 2/3)
Step-by-step explanation:
a) total of frequencies is 90 and frequency for a 3 is 11
however, the question said if the dice is rolled once more, then that raises the 11 to 12 and the frequency total from 90 to 91
let 'x' = # of sixes rolled out of 500 times
b) 12/90 = x/500
cross-multiply:
90x = 6000
x = 66 2/3
Answer: Option 'd' is correct.
Step-by-step explanation:
Since we have given that
Margin of error = 0.5 years
Standard deviation = 5
At 90% confidence, z = 1.645
We need to find the minimum size of the sample they must take.
So,
Hence, Option 'd' is correct.

show how you know .. :D good rhyme
Step-by-step explanation:
park = 4" x 6" ( inches) small park
but one inch = 30 miles ooh big park
4*30 X 6*30
120 X 180 miles... like a big game range? :? very big
since we only have 6 square inches to fit the map into... then.. what size of map would fit? what size equals 6 inches? 2 x 3 ? hmm yes that's 6
soooo shrink the 4" x 6" to 2"x 3" so the scale needs to double or
1 inch = 60 miles
2"*60 x 3"*60 = 120 x 180 miles.. looks good try that :)
