The standard deviation for the number of seeds germinating in each batch is 1.3
<u>Solution:</u>
<em><u>In binomial distribution, standard deviation is given as:</u></em>

Where "n" is the number of observations
"p" is probability of getting success
We are given that:
Total batches of seed = 8
Probability that a radish seed will germinate is 0.7
Here success is getting radish seed germinated
<em><u>Then, the standard deviation for the number of seeds germinating in each batch.</u></em>
Plugging in values in formula, we get

Therefore the standard deviation for the number of seeds germinating in each batch is 1.3
Answer:
hmmmmm not sure
Step-by-step explanation:
Answer:81
Step-by-step explanation:
85% + 50% - 60%
135% - 60%
50 = x^2 - 9x + 14
x^2 - 9x + 14 - 50 = 0
x^2 - 9x - 36 = 0
(x - 12)(x + 3) = 0
x - 12 = 0
x = 12 <==
x + 3 = 0
x = -3......not this one
