The bases of an isosceles trapezoid are represented by 4x and 2x.. The height of the trapezoid is represented by (x − 6). Which
Igoryamba
The area of a trapezoid is calculated by the equation,
                          A = 0.5(b₁ + b₂)h
where b₁ and b₂ are the bases and h is the height. When we substitute the given expression for the dimensions in the given,
                          A = 0.5(4x + 2x)(x - 6)
                          A = 0.5(6x)(x - 6) = 3x² - 18
Thus, the answer is letter A.

A physiological psychologist has performed an experiment to determine if a particular drug, smartozine, affects maze learning in
Elis [28]

Answer:

The critical value of F for this situation is 2.975.

Step-by-step explanation:

A test is being performed to determine if a particular drug, smartozine, affects maze learning in rats.

The groups are divided as follows:

  • Three groups of 8 rats each are injected with one of three different doses of smartozine.
  • The fourth group of 6 rats is injected with a saline solution as a control.

So, there were in total <em>k</em> = 4 groups with <em>n</em> = 30 rats.

The significance level of the test is, <em>α</em> = 0.05.

Compute the critical value of <em>F</em> as follows:

F_{\alpha, (k-1, n-k)}=F_{0.05, (4-1, 30-4)}=F_{0.05, (3,26)}=2.975

*Use the <em>F</em>-table.

Thus, the critical value of F for this situation is 2.975.
