Answer:
Option E) 61.6
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 100 bushels per acre
Standard Deviation, σ = 30 bushels per acre
We assume that the distribution of yield is a bell shaped distribution that is a normal distribution.
Formula:

P(X>x) = 0.90
We have to find the value of x such that the probability is 0.90
P(X > x)
Calculation the value from standard normal table, we have,

Hence, the yield of 61.6 bushels per acre or more would save the seed.
Answer:
3x+1 is the correct answer

sorry, I think yr question is incomplete.
Answer:
$900
Step-by-step explanation:
If the $810 is the price after 10% discount that means
$810 is 90% of the original price
So we divide 810 / 90% or 810 / 0.9
to get $900 as final price
Answer:
Fraction of drink that is water = = 0.875 = 87.5 %
Explanation:
400 ml of squash is made by mixing 50 ml of cordial with water.
Total volume of squash = 400 ml
Total volume of cordial = 50 ml
Total volume of water = 400 - 50 = 350 ml
Fraction of drink that is water = Volume of water/ Volume of squash
= 350/400
= 7/8
= 0.875 = 87.5 %
