Answer:
$234
Step-by-step explanation:
First we need to define profits. Profits are Income minus Expenses:
P = I - E
We know profits are $414, so:
414 = I - E
We also can calculate income, as it is equal to price by the sales:
I = p*Q
Here she sold 90 kgs at $7.20 b kg. So:
I = p*Q = 7.20 * 90 = 648
So, replacing in profits equation:
414 = I - E
414 = 648 - E
If we sum E in both sides:
414 + E = 648 - E + E = 648
414 + E = 648
Now, subtracting 414 in both sides:
414 + E - 414 = 648 - 414
E = 234
So, her expenses are $234
11/12 - 7/12 = 4/12 = 1/3

Answer:
Explained below
Step-by-step explanation:
A) A skewed distribution in a dataset is when the median is not equal to the mean in such a manner that the bell curve is tilted to the left or right.
B) If in a data set, if there are outliers which are extremely large or extremely small in comparison to other values in that same dataset, then we can say that such a curve will be pulled towards the outlier and thus the distribution is skewed.
Also, if the curve is inclined to the left, it means there are few extreme values to the left and it is negatively skewed.
Similarly, if the curve is inclined to the right, it means there are few extreme values to the right and is positively skewed.
C) Example of a research question is;
If in a developed country where the poverty level is about 0%, if we collect the data of income of the households, we will discover majority of people with average income and very few people with extreme high levels of income. This condition means the data is positively skewed.
Answer:
B
Step-by-step explanation:
The solution is the point of intersection of the 2 lines
The lines intersect at (- 3, - 4 ), then
f(x) = g(x) has solution x = - 3
Answer: (0, -6)
Step-by-step explanation:
The center is the midpoint of the diameter, meaning that the coordinates of Y must be (0, -6).
