The two questions aren’t there?
Answer:
The mean is 52.
Step-by-step explanation:
The mean is the sum of all elements divided by the number of elements.
In this problem, we have that:
Elements
56 47 48 52 62 59 49 56 43 48
Sum
Number of Elements
10 elements
The mean is
Correct. Use the commutative property<span> to rearrange the expression so that compatible numbers are next to each other, and then </span>use the associative property<span> to group them. Incorrect. Check your addition and subtraction, and think about the order in which you are adding these numbers.</span>
From the given scenario in this item, we can say that the sum of x and y is 500. By the aluminum balance, the equation that we can formulate from this,
0.25x + 0.40y = (500)(0.35)
The system of linear equations that can best express the given is,
x + y = 500
0.25x + 0.40y = 175
Answer:
y= x^2-14x+36
The equation is already in the standard form.
