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.

Write a description of how you would calculate the area of the shaded space include the answer.
olga_2 [115]

Answer:

The area of shaded region is 25.5 units³

Step-by-step explanation:

Step 1 , you have to find the area of rectangle and triangle using the formulas :

Rectangle :

area = length \times width

Let length = 5 units,

Let width = 6 units,

area = 5 \times 6

area = 30 \:  \:  {units}^{2}

Triangle :

area =  \frac{1}{2}  \times base \times height

Let base = 3 units,

Let height = 3 units,

area =  \frac{1}{2}   \times 3 \times 3

area =  \frac{1}{2}  \times 9

area = 4.5 \:  \:  \:  {units}^{2}

Step 2 , in order to find the shaded region, you have to substract the area of triangle from the area of rectangle (As the triangle is not shaded) :

area = 30 - 4.5

area = 25.5 \:  \:  \:  {units}^{2}

Someone help i need this solved by elimination
marshall27 [118]

Answer:

The value of x is 4 and y is (-9)

Step-by-step explanation:

<h3><u>Given</u>;</h3>
  • x + 2y = -14
  • x – y = 13
<h3><u>To </u><u>Find</u>;</h3>
  • Value of x
  • Value of y
  • By Elimination Method

Now, Name the equation

x + 2y = -14 ...(1)

x – y = 13 ...(2)

Now,

x + 2y = -14

x – y = 13

<u>– + –</u>

3y = -27

y = -9

Now, put the value of y in equation 2

x – y = 13

x – (-9) = 13

x + 9 = 13

x = 4

Thus, The value of x is 4 and y is (-9)

<h3><u>For </u><u>Verification</u>;</h3>

x + 2y = -14

4 + 2(-9) = -14

4 – 18 = -14

-14 = -14

x – y = 13

4 – (-9) = 13

4 + 9 = 13

13 = 13

Hence, L.H.S = R.H.S
