An = a1 * r^(n-1)
-405 = -5*3^(n-1)
3^(n-1) = 81
3^4 = 81 so n-1 = 3 and n = 4
Sn = S4 = -5 (1 - 3^4) / ( 1 - 3) = 400 / -2 = -200 Answer
Answer:
900
Step-by-step explanation
That would be 3 * 300 = 900
Step-by-step explanation:
There is figures in you question. Please check your question.
Answer:
The last one is the answer.
The answer is 95.4525 percent because you would use an equation
n!/(r!(n-r)! x (P)^x * (1-P)^(n-x)
Plug in the number correspondingly
N= 10
R= 1 , 2 , 3 , 4 , 5 , 6 (You will have to do each individual, if you have a Ti-nspire calculator however there is a built program called binomialcdf.
P= .37
x = r
After plugging this is the achieved answer is 95.4525
(.0578 + .1529 + .2394 + .2461 + .1734 + .0849) x 100
additive may be a little off due to rounding.
