Answer:
Step-by-step explanation:
A positive parabola is one that has a + sign out front or no sign at all (and the positive is understood). A positive parabola opens like a cup with a bottom. Therefore, the positive parabola has a min value. A negative parabola opens upside down, like a mountain with a peak. Therefore, the negative parabola has a max value.

the proportion of students that like the silver calculator is 0.4 while the proportion of students that like the black calculator is 0.6. More students like the black calculator
the proportion of students that prefer the black model 77 calculator is 0.3 while the proportion of students that prefer the silver model 55 is 0.25. More students prefer the black model 77 calculator
the proportion of students that prefer the model 66 calculator is 0.15 while the proportion of students that prefer the model 55 calculator is 0.35. More students prefer the model 55
the fewest student prefer the silver model 66 calculator because it has the lowest proportion
A right triangles hypotenuse is the square root of both of the other side squared. The formula for this is a^2 + b^2= c^2, with c being the longest side. So 10 squared is 100, 13 squared is 169, but. 17 squared is 289. The sum of the other two sides are 269. So it doesn’t equal

Answer:
ounces of marigold seeds.
Step-by-step explanation:
We have been given that Jane uses 2/5 of an ounce of lupine seeds for every ounce of Marigold seeds. We are asked to find the ounces of Marigold seeds, which Jane will use, if she used one ounce of lupine seeds.
We will use proportions to solve our given problem.
![\frac{\text{Marigold seeds}}{\text{Lupine seeds}}=\frac{1}{\frac{2}{5}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BMarigold%20seeds%7D%7D%7B%5Ctext%7BLupine%20seeds%7D%7D%3D%5Cfrac%7B1%7D%7B%5Cfrac%7B2%7D%7B5%7D%7D)
Let us simplify our proportion as shown below:
![\frac{\text{Marigold seeds}}{\text{Lupine seeds}}=\frac{1\cdot 5}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BMarigold%20seeds%7D%7D%7B%5Ctext%7BLupine%20seeds%7D%7D%3D%5Cfrac%7B1%5Ccdot%205%7D%7B2%7D)
![\frac{\text{Marigold seeds}}{\text{Lupine seeds}}=\frac{5}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BMarigold%20seeds%7D%7D%7B%5Ctext%7BLupine%20seeds%7D%7D%3D%5Cfrac%7B5%7D%7B2%7D)
Since Jane used 1 pounce of lupine seeds, so we will substitute this value in our proportion as:
![\frac{\text{Marigold seeds}}{1}=\frac{5}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BMarigold%20seeds%7D%7D%7B1%7D%3D%5Cfrac%7B5%7D%7B2%7D)
![\text{Marigold seeds}}=\frac{5}{2}](https://tex.z-dn.net/?f=%5Ctext%7BMarigold%20seeds%7D%7D%3D%5Cfrac%7B5%7D%7B2%7D)
Therefore, Jane will use
ounces of marigold seeds, if she used one ounce of lupine seeds.
