Answer: option 1 is the correct answer
Step-by-step explanation:
Number of times for which the die was rolled is 360. It means that our sample size, n is 360.
The probability of rolling a 5 or a 6 is 1/3. It means that probability of success,p = 1/3. The probability of failure,q is
1 - probability of success. It becomes
1 - 1/3 = 2/3
The formula for standard deviation is expressed as
√npq. Therefore
Standard deviation = √360 × 1/3 × 2/3
= √80 = 8.9443
Standard deviation is approximately 8.9
Step-by-step explanation:
here's the solution: -
if the given triangles are similar, then their corresponding sides will be in proportion, so

THE SURFACE AREA IS 3220CM^2
1/2 = 4/8
3/8 = 3/8
8 is the common denominator between these two fractions
