Answer:
10+2(50-1)
Step-by-step explanation:
This is an arithmetic sequence
We know the first term a1 = 10
The common difference, d = 2
an = a1+d(n-1)
We want to find the number of terms when n = 50
a50 = 10+2(50-1)

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
