Slope is 2/-1 or -2. Because you go up twice and then you go left once.
Zina [86]2 years ago

Answer:

y = -2x - 1

See image

Step-by-step explanation:

The "slope-intercept" form of the equation is the

y = mx + b form

So you need to find the slope (m) and the y-intercept (b), which you are able to find on the image in the question.

Slope (m) tells how steep a line is and whether it goes up or down from left to right. It also works just like directions, from any point on the line to any other point on the line.

The y-intercept (b) is the point on the line where the line crosses the y-axis.

The slope is -2 and the y-intercept is -1

So the equation is

y = -2x - 1

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.
