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

The advertising department of a nationally circulated magazine wishes to estimate the mean age of its subscribers within 0.5 yea
zhenek [66]

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,

n=(\dfrac{z\sigma}{E})^2\\\\n=(\dfrac{1.645\times 5}{0.5})^2\\\\n=270.6\\\\n\approx 271

Hence, Option 'd' is correct.

I need help with this problem
Anit [1.1K]

Answer:

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 :)
