The answer choices are in point-slope form.
point slope form = y-y1 = m(x-x1)
y1 is the y coordinate of the point give, m is the slope and x1 is the x coordinate of the point given.
SO the answer would be:
y-11=-4(x+2)
Hope this helps :)
step 1
Find the <span>average growth per year of the populations of rabbits farm A
</span><span>Over the first 2 years
for t=0
</span>numbers of rabbits=5 (is not exact)
for t=2
numbers of rabbits=40
average=[40-5]/2---------> 17.5
step 2
Find the average growth per year of the populations of rabbits farm B
Over the first 2 years
for t=0
numbers of rabbits=5 (is not exact)
for t=2
numbers of rabbits=30
average=[30-5]/2---------> 12.5
step 3
<span>Compare the average growth per year of the populations of rabbits on both farms
farm A=17.5
farm B=12.5
</span><span>the average rate of population growth of rabbits in farm A is greater than average rate of population growth of rabbits in farm B by about 5 rabbits per year.
therefore
the answer is the option C)
</span>the average rate of population growth of rabbits in farm A is greater than average rate of population growth of rabbits in farm B by about 6 rabbits per year.
Answer:
c = 6 + 0.39p or c = 0.39p + 6
Step-by-step explanation:
p = #pounds
c = total cost to ship
cost c = $6 + $0.39p ($6 flat fee + $0.39 per pound)
Given:
z = (x - μ)/σ = z value
x = independent variable = 11
μ = mean = 8
σ = standard deviation = 3
Solution:
X ~ N (8, 3)
For day 1, n = 5
P (X < = 11) = P (Z < = 11 – 8 / 3/Sqrt5) = P (Z <
=2.23) = 0.987126
For day 1, n = 6
P (X < = 11) = P (Z < = 11 – 8 / 3/sqrt6) = P (Z <
=2.45) = 0.992857
For both days:
P (X <= 11) = P (X <= 11) = (0.987126) (0.992857) =
0.9801
