skskhfkakakan what is this haha
Step-by-step explanation:
seems to be multiplication, because the differences between the numbers change.
so, let's find the factor.
2 × f = 5
f = 5/2
5 × f = 5 × 5/2 = 25/2
ok, the factor 5/2 is confirmed.
a1 = 2
a2 = a1 × 5/2 = 2 × 5/2 = 10/2 = 5
a3 = a2 × 5/2 = a1 × 5/2 × 5/2 = 2 × 5/2 × 5/2 = 25/2
an = an-1 × 5/2 = a1 × (5/2)^(n-1) = 2 × (5/2)^(n-1)
a9 = 2 × (5/2)⁸ = 2 × 390,625/256 =
= 390,625/128 = 3,051.7578125
The answer is 200. how I got my answer.
I simply realised that I could not multiply 40% easily to 100%. So I spit it in half, and made 20%=40. then I multiplied 20%×5=100% and I also multiplied 40×5=200.
I hope this helps!
Answer:
std dev = 0.625
Step-by-step explanation:
Given that weights of bags of potato chips coming from a factory follow a normal distribution with mean 12.8 ounces and standard deviation .6 ounces.
We must change std deviation such that
P(X<12) =0.01
Mean would remain the same as 12.8 oz
From normal distribution score we can find
10th percentile is -1.28\
i.e. we must have
Std deviation should be 0.625
Do you have the questions for d and e?
