The base is twice the height, or b = 2h. So, h = b/2. The area of a right triangle is (1/2)*b*h, and replacing h with b/2 you have (1/2)*b*(b/2), or (1/4)*b^2.So to write this it is<span> A(b) = (1/4)*b^2 for b >= 0</span>
Answer:
d. In three-way ANOVA, it equals the block sample mean.
Step-by-step explanation:
Blocks variation is the analysis of variance. Block variations equals sum of squared deviation between each block sample mean. ANOVA is a statistical technique designed to test mean of one or more quantitative populations. In two-way ANOVA it equals the block mean. Column block means square is three-way ANOVA. Block means square in two-way ANOVA without interactions the treatment mean square.
<span>(230 + w) x ( t ) = ( 275 )
(230 - w) x ( t ) = ( 185)
t = 275 / (230 + w)
t = 185 / (230 - w)
275 / (230 + w) = 185 / (230 - w)
275(230 - w) = 185(230 + w)
63250 - 275w = 42550 + 185w
20700 = 460w
w = 45mph

Hello! 3x + 20 and 8x - 5 are equal. To find the value of "x", we should set up and solve an equation. It would be written like this:
3x + 20 = 8x - 5
First off, subtract 3x from both sides in order to get 20 = 5x - 5. Add 5 to both sides to get 25 = 5x. Now, divide each side by 5 to isolate the "x". 25/5 is 5. Now, let's plug in the value and see if it works. 3 * 5 is 15. 15 + 20 is 35. 8 * 5 is 40. 40 - 5 is 35. 35 = 35. There. x = 5.
