Twelve volunteers were asked to sort two sets of 200 cards into two piles. One set of cards were bright red and bright green. The other set of cards were black and white. The order (red/green first or black/white first) was determined by a coin toss with ample time between the two tasks to lessen the effect of practice. The time (in seconds) to complete each of the two tasks are given: Card Sort Completion (a) Assuming the conditions for inference are met, what statistical test should be used to determine if there is a significant difference in the mean time required to sort the two sets of cards

the image of (6, 9) under a dilation is (4, 6). the scale factor is

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.

step-by-step explanation:

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3
