Answer:
1 1/4 pounds
Step-by-step explanation:
You can write the equation ...
(1/2) lb = (2/5) × container
Multiplying by the inverse of 2/5 gives ...
(1/2)·(5/2) lb = container
5/4 lb = container
container = 1 1/4 lb
Answer:
24.6 < μ < 27.2
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 25.9 - 1.3 = 24.6 pounds.
The upper end of the interval is the sample mean added to M. So it is 25.9 + 1.3 = 27.2 pounds.
So the correct answer is:
24.6 < μ < 27.2
The solution for the problem is as follows:
((12x + 15y)/228) = 13
x + y =228
x = kentucky bluegrass
<span>y = chewings fescue
</span>
By systems of linear equations, the answers would be:
x = 152
y = 76
Therefore, there should be 152 pounds of Kentucky bluegrass to be used and 76 pounds of chewings fescue.

Answer:
Step-by-step explanation:
The general formula for this sequence is a(n) = a(1)*(-1/4)^(n - 1). We don't yet know a(1).
If a(3) = 128, then 128 = a(1)*(-1/4)^(3 - 1), or
128 = a(1)*(1/16)
and so a(1) = 128/16
resulting in the specific formua a(n) = 8(-1/4)^(n - 1)
Now let's find a(7):
a(7) = 8(-1/4)^1 * (-1/4)^(6)
or
a(7) = 8(-1/4)^7
