Words were displayed on a computer screen with background colors of red and blue. Results from scores on a test of word recall a
kherson [118]

Answer:

Yes, the background color appear to have an effect on the variation of word recall​ scores

Step-by-step explanation:

Given that results from scores on a test of word recall are given are as follows:

Two test scores have independent means and having normal distribution.

H_0: Means are equal\\H_a: Means are not equal

(Two tailed test at 5% significance level)

Group   Group One     Group Two  

Mean    15.1400 12.4200

SD              5.9100 5.4200

SEM     0.9990 0.8910

N                35       37      

The mean of Group One minus Group Two equals 2.7200

standard error of difference = 1.335

Hence t statistic = 2.0369

p value = 0.0454

Since p <0.05 we reject null hypothesis

Yes, the background color appear to have an effect on the variation of word recall​ scores

In the slope-intercept form, which variable<br> represents the slope/measure of change?
Brums [2.3K]

Step-by-step explanation:

Hey there!

We know that the slope intercept is; y = mx+b.

Where "m" represents the slope. And "b" represents the y-intercept.

Example:

If the question is as; y = 3x +8

Then your slope of the slope intercept form is "3" where as "8" is y-intercept.

So, the variable"m" represents the slope.

Determine the equation of the circle graphed below.<br><br>screenshot is below - from delta math
Elanso [62]

Answer:

\displaystyle \large{(x-5)^2+(y-2)^2=25}

Step-by-step explanation:

Given:

  • Center = (5,2)
  • Endpoint = (8,6)

First, find radius via distance between center and endpoint. The formula of distance between two points is:

\displaystyle \large{\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}

Determine:

  • \displaystyle \large{(x_1,y_1)=(5,2)}
  • \displaystyle \large{(x_2,y_2)=(8,6)}

Hence:

\displaystyle \large{\sqrt{(8-5)^2+(6-2)^2}}\\\displaystyle \large{\sqrt{(3)^2+(4)^2}}\\\displaystyle \large{\sqrt{9+16} = \sqrt{25} = 5}

Therefore, the radius is 5.

Then we can substitute center and radius in circle equation. The equation of a circle is:

\displaystyle \large{(x-h)^2+(y-k)^2=r^2}

Our center is at (h,k) which is (5,2) and radius beings 5.

Hence, your answer is:

\displaystyle \large{(x-5)^2+(y-2)^2=25}
