Answer:

B) 13

Step-by-step explanation:

Average age means to calculate mean:

Mean = (Sum of all numbers)/(Number of numbers)

Mean = (14 + 14.5 + 12 + 11.5 + 15 + 13 + 10.5 + 13.5)/8

Mean = (104)/8

Mean = 13

qwelly [4]
Okay, this is a proportion question. they make 45 flowers every 1 hour and 25 minutes, or 45/85(85 is equivalent to 1 hour and 25 minutes). and they made 100 flowers at the same rate as the first day. so you need to know how long it took them to make 100 flowers, if they make 45 every 85 minutes. so 45 (flowers) to 85 (minutes) = 100 (flowers) to x (minutes). or 45/85=100/x. so when you work that out, I came to 189 minutes, which is 3 hours and 9 minutes, so they stopped at 4:24. But you could round and get 4:25. Hope I didn't confuse you!

4t+6s=4524
t+s=925

Multiply the second equation by -4 to cancel the variable t
4t+6s=4524
-4t-4s=-3700
2s = 824
Divide both sides by 2
S= 412

925-412= 513
T=513

Which is the best approximation of the solutions to the system of equations graphed below?
Neko [114]

According to the direct inspection, we conclude that the best approximation of the two solutions to the system of <em>quadratic</em> equations are (x₁, y₁) = (- 1, 0) and (x₂, y₂) = (1, 2.5). (Correct choice: C)

<h3>What is the solution of a nonlinear system formed by two quadratic equations?</h3>

Herein we have two parabolae, that is, polynomials of the form a · x² + b · x + c, that pass through each other twice according to the image attached to this question. We need to estimate the location of the points by visual inspection on the <em>Cartesian</em> plane.

According to the direct inspection, we conclude that the best approximation of the two solutions, that is, the point where the two parabolae intercepts each other, to the system of two <em>quadratic</em> equations are (x₁, y₁) = (- 1, 0) and (x₂, y₂) = (1, 2.5). (Correct choice: C)
