Answer:
s = 180
Step-by-step explanation:
s is the total number of seventh-grade students
1/10s take French which is 18
1/10s = 18
s = 18(10)
s = 180
N = number of seeds planted
P = probability of germination
K = number that germinated
Using probability calculation:
p(x = k) = (n k) x 0.90^K x 0.10^n-k
p(10) = (12 10) x 0.90^10 x 0.10^2
P(10) = 0.2310
Answer:
The probability that their mean life will be longer than 13 years = .9943 or 99.43%
Step-by-step explanation:
Given -
Mean
= 15 years
Standard deviation
= 3.7 years
Sample size ( n ) =22
Let
be the mean life of manufacturing items
the probability that their mean life will be longer than 13 years =
=

= 
=
Using Z table
= 1 - .0057
= .9943
Step-by-step explanation:
3x+6+4x-20=10
