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

Answer:
y = -8x -15
Step-by-step explanation:
It can be useful to start with the point-slope form when you are given a point and a slope.
y -k = m(x -h) . . . . . line with slope m through point (h, k)
For the given line, this equation is ...
y +7 = -8(x +1)
y = -8x -8 -7 . . . . eliminate parentheses, subtract 7
y = -8x -15 . . . . . slope-intercept form
Part a
The sample size is large enough to use the central limit theorem because it is greater than 30.
Part b.
The mean of the sampling distribution is 62000.
The standard error is computed as
Part c.
Compute for the corresponding z-score of more than 2700 from the population mean.
Therefore,
The sample size is large enough to use the central limit theorem because it is greater than 30.
Part b.

The standard error is computed as
Part c.
Compute for the corresponding z-score of more than 2700 from the population mean.
Therefore,
Answer:
x =
Step-by-step explanation:
Given
4x + 6 = 11 ( subtract 6 from both sides )
4x = 5 ( divide both sides by 4 )
x = = 1.25
