25 mina is testing different types of heat lamps to determine which type is most effective for growing strawberry bushes. she purchases two different types of lamps from a local store. mina applies brand a to one area of the yard and brand b to another area of the yard, both of which receive full sunlight. she waters the area with brand b daily; she waters the area with brand a every other day. at the end of the study, mina concludes brand b is more effective in growing strawberry bushes. is mina's conclusion valid? explain why or why not.

No, her conclusion is not valid.

Step-by-step explanation:

In order to determine whether 1 lamp is more effective than the other, all other variables have to be the same.

Because Brand B was watered daily and Brand A was watered every other day, there is no way of knowing if the results were conclusive because of the heat lamps or the different watering patterns.

Hope this helps:)

it isnt valid

Step-by-step explanation:

she needs to keep the watering consistent for both areas to keep the constants the same

Step-by-step explanation:

Ok, this problem is on construction in mathematics.

also, see attached a rough sketch of the two constructions.

The similarities, as can be seen, is that for both constructions, we need to two major points to obtain a bisector, for the line segment the major points are (A and B) and for the angle segment the points are(P and Q)

The difference between the two construction is that the line segment needs basically two bisectors to equally divide the line located at (O and P), while the angle segment needs just one bisector at (O) to bisect the angle.
