At first you may get confused but look at those numbers carefully :)
as you see first result is divisible buy one of the product (second product in all cases is unknown)
so let's check where it will lead us :)
Now you can clearly see that every number was multiplied by number 1 higher than itself.
etc...
it means that after equation sign there should be
because

First we need to graph the given values.
there are total 16 data so x-value can be taken as 1,2,3,...,16
given values will be assigned as y-values as shown in attached table.
Now we just graph those points to see the type of skew.
From graph we see that points are very close and almost in the shape of a line. Lines seems to be moving upward when going to the right side.
Hence correct answer will be "positive skew".
Answer:
Option C. Marcelina spends less that the intended amount of money and buy the correct amount of corn
Step-by-step explanation:
<u><em>The complete picture of the question in the attached figure</em></u>
Let
x----> is the amount of white corn she buys
y ---> is the amount of yellow corn she buys
we know that
She needs to buy 50 kg of corn in total
so
----> equation A
She wants to spend $12 dollars total
so
----> equation B
The solution of the system of equations is the intersection point both graphs
The solution is the point (30,20)
That means
Marcelina needs to buy 30 kg of white corn and 20 kg of yellow corn
we have the ordered pair D(15.35)
That means
15 kg of white corn and 35 kg of yellow corn
therefore
Total kg of corn bought is
Total spend is
therefore
Marcelina spends less that the intended amount of money and buy the correct amount of corn
