The <u>correct answer</u> is:

Experiment

Explanation:

In an experiment, one group is given a treatment while at least one other group is not.  After the treatment is finished, the results of the group that receive the treatment are compared with the results of the group (or groups) that do not receive the treatment, to determine if the treatment had any effect on the group.

In this problem, the different groups are the classes.  Some classes use the new method, which is the treatment, while other classes do not.  At the end of the year, the reading results of each class are compared to see if the treatment (new method) had any effect.

Nathaniel builds birds and birdhouses using Lego blocks. Let B represent the number of birds and H represent the number of birdh
N76 [4]

Answer:

At-most 3 birdhouses.

Step-by-step explanation:

Let B represent the number of birds and H represent the number of birdhouses that Nathaniel can build with his Lego blocks.

We have been given that Nathaniel builds birds and birdhouses using Lego blocks. The inequality 43B+215H\leq3000 represents the number of birds and birdhouses Nathaniel could build.

To find the number of birdhouses that Nathaniel can build after making 50 birds, we will substitute B=50 in our given inequality and then solve for H.

43*50+215H\leq3000

2150+215H\leq3000

Let us subtract 2150 from both sides of our inequality.

2150-2150+215H\leq3000-2150

215H\leq850

Let us divide both both sides of our inequality by 215.

\frac{215H}{215}\leq\frac{850}{215}

H\leq3.953488

As Nathaniel can make build less than or equal to 3.953488 and the biggest integer less than or equal to 3.953 is 3, therefore, Nathaniel can build at-most 3 birdhouses with remaining Lego blocks.

True or false: Polar equations can describe graphs as functions, even when their equations in the rectangular coordinate system
pshichka [43]
The statement above is true. Polar equations indeed can describe graphs as functions, even if when the equations in the rectangular coordinate system are not one of the functions. Polar equations can be graphed accurately using hands by using the Polar Coordinate System.

Use the remainder Theorem and synthetic division to find p(3) for p(x) = x4 + x3 -x2 - 2x
maxonik [38]

You do not need to use the remainder theorem to find p(3). Just plugin 3 where the x is located in

x^4 + x^3 - x^2 - 2x

3^4 + 3^3 - 3^2 - 2(3) = 93

Answer is a.
