The situation would come as follows: "Does Andrew make more money than Laura?"
The question can only be answered with a yes or no. Which does not generate any statistics because they are characterized by having an inherent variability in the data used to answer the question. And in this question there is no variability since if you earn more money or not because they are focused on itself, there is a positive or negative side and from there there is no variation.
Therefore NOT a statistical question.
x+y=46 and 1.75x+2y=89.50 can be used to determine the number of pounds of blueberries sold and the number of pounds of apples sold, where x represents the pounds of blueberries sold and y represents the pounds of apples sold.
Step-by-step explanation:
Cost of one pound of blueberries = $1.75
Cost of one pound of apples = $2
Total worth = $89.50
Total sold = 46 pounds.
Let,
x be the pounds of blueberries sold.
y be the pounds of apples sold
According to given statement;
x+y=46 Eqn 1
1.75x+2y=89.50 Eqn 2
x+y=46 and 1.75x+2y=89.50 can be used to determine the number of pounds of blueberries sold and the number of pounds of apples sold, where x represents the pounds of blueberries sold and y represents the pounds of apples sold.

Answer:
-1.514
Step-by-step explanation:
8/15 = 0.53
Equation:-
0.53/(-0.35)
=> -1.5142857142857145 = -1.514 (Approx.)
Answer:
A function is a relation in which each input has only one output. In the relation, y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y.
Step-by-step explanation:
For every x there is exactly one y value. We can forgive a function if some values of x do not have a y, but if there is more than one y for even one value of x, then the relation is not a function.
1. The problem statement tells you to find "the area of the hexagonal face".
2. If we assume the intent is to find the shaded area of the face only, it differs from the area of a regular hexagon in that there is a hole in the middle.
3. You must find the area of the regular hexagon, and subtract the area of the circular hole in the middle.
4. The formula for the area of a circle in terms of its radius is
... A = πr²
5. The formula for the area of a regular hexagon in terms of the radius of the circumcircle is
... A = (3√3)/2·r²
6. The radius of the circumcircle of the regular hexagon is given. No additional information is needed.
7. You can use the trig functions of the angles of an equilateral triangle to find the apothem, but there is no need for that when you use the formula of 5.
8. All this is unnecessary. The apothem is (8 mm)·(√3)/2 = 4√3 mm ≈ 6.9282 mm, the shorter leg is (8 mm)·(1/2) = 4 mm. The perimeter is 6·8 mm = 48 mm.
9. The area of the hexagon is
... A = 3√3/2·(8 mm)² = 96√3 mm² ≈ 166.277 mm²
10. The area of the circle is
... A = π·(4 mm)² = 16π mm² ≈ 50.265 mm²
11. The area of the hexagonal face is approximately ...
... 166.277 mm² - 50.265 mm² = 116.01 mm²
