Answer:
About 786 would be expected to yield more than 180 bushels of corn per acre
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
Assuming you want the expression to be simplified.
We begin with the following:
Simplify the first part,
. That is 25. Now we have this:
Next, simplify
, which is 1/3, and get this:
The next part is
. Simplify the denominator,
, which is 81. Simplify the numerator, which is 1/125. Then divide 1/125 by 81, which we will keep as a fraction for simplicity's sake, but simplify it to
. Now we have:
Now simplify
, which is 0.2, or 1/5. Now we have:
Finally, simplify
. That is 1/27. We have:
Lastly, multiply them all together! Now we are done, with the product of:
That certainly did take a while to type in all the LaTex, so I really hope that helped!
Note- if anything isn't working with the LaTex, just tell me and I'll fix it! (:
Answer:
800
Step-by-step explanation:
If you multiply 1 tenth by 80 you will get 800 over 1.
800/1
800/1 = 800.
Ah, direct variation/proportion.
That is simply a linear equation with a y-intercept of 0.
So... let's solve this.
Simply put, a direct variation multiplies the x-value by a constant to get the y-value.
Let's take the point
on this graph and solve for the constant of proportionality:
We easily solve that and get our answer of
. (B)
Given,
Side = 7 cm
We know that,
Volume of a cube = side³
So, volume of Harry's cube
= (7 cm)³
= 343 cm³
