10 ounces of orange juice for $2.40

each ounce of orange juice for 8 ounces is 0.26

each ounce of orange juice for the 10 ounces would only be 0.24

The minimum of a parabola is located at (-1,-3). the point (0,1) is also on the graph. which equation can be solved to determine
mario62 [17]

Answer:

The equation that can be used to solve for a is 1 = a(0=1)²-3.

Explanation:

In this case, I would model the parabola in vertex form.  Vertex form is y = a(x-h)²+k, where (h,k) is the vertex of the parabola.  Using the information from the question, we can plug in values to get 1 = a(0+1)²-3.  (This could be simplified as 1 = a(1)²-3 ⇒ 1 = a-3 ⇒ a = 4, but we are only interested in finding the equation that can solve for a.)

iren2701 [21]

Answer:

mean = 172.72cm and variance = 645.16

Step-by-step explanation:

1 inch = 2.54 centimetres

mean = 68 * 2.54 = 172.72 cm

standard deviation = 10 *2.54 = 25.4 cm

variance = square of standard deviation

variance = 25.4 * 25.4

variance = 645.16 cm
