Hello,
V=π R²h=355=5*71
1) h=355 , R=√(1/π) ,V=π*(√(1/π)²*355=π/π * 355=355
2) h=5, R=√(71/π), V=π*(√(71/π))²*5=71*5=355
3) a>0,h=a, R=√(355/(πa)), V=π*(√(355/(πa)))²*a=π*355/(πa) * a=355
Answer:
x
Step-by-step explanation:
Answer:
Option A is correct.
y = 35.4 bushels per acre when rainfall = 7.1 inches
Step-by-step explanation:
An image of the steps to obtain the equation that relates x to y is attached to this answer.
n = number of variables = 9
μₓ = mean of variable x (rainfall in inches)
μᵧ = mean of variable y (yield in bushels per acre)
σₓ = standard deviation of variable x (rainfall in inches)
σᵧ = standard deviation of variable y (yield in bushels per acre)
y = 4.379x + 4.268
when x = 7.1
y = 4.379(7.1) + 4.268 = 35.3589 = 35.4 bushels per acre.
Step-by-step explanation:
2 horror and 6 drama DVDs.
Let x be the no. Of horror dvds
15 = 7+ x+x+4
4=2x
x=2
