= [3x3^-2x(-2)^6/2x3^-1x(-2)^5]^2 = 1
1/5 would be the correct one.
Take the width of the field (90 meters) and square it. Then take the length of the field (120 meters) and square it. The you add the two squares together and then find the square root of your answer. So basically 90^2 + 120^2 = 22500. then find the square root of 22500 which is 150 meters. 150 meters is your answer.
500 x 1.05^4
it's 4 periods because the interest rate is compounded yearly. 5 percent yearly increase is equal to P x 1.05
Answer:
32
Step-by-step explanation:
Possible outcomes in a fair sided die 1,2,3,4,5,6 = 6 possible outcomes
Odd numbers = 1,3,5 = 3 odd numbers
Probability of rolling an odd number = 
= 
Total number of rolls = 64
expected number of odd number rolls in 64 roll,
= x 64 = 32
