Answer:
90
Step-by-step explanation:
Mean:
(88 + 88 + 88 + 87 + 84 + 97 + 95)/7

Answer:
50
Step-by-step explanation:
So you can think of this by grouping it like this:
(1-2) + (3-4) + (5-6) + ... + (97-98) + 99
which is equal to: (-1) + (-1) + (-1)... + (-1) + 99
(each group is equal to -1, and 99 won't have a pair since it's the last one)
then, find how many groups of -1 there are:
the groups start at 1 and end at 98, but there are two in each group, so 98/2 = 49. this means there are 49 groups.
so now, you know that there are 49 -1s, so 49 * (-1) = -49.
finally, you can't forget the extra 99 that didn't have a pair, so -49 + 99 = 50.

Answer:
Choose the figure with side lengths 0.5, 1, 2 and 2.5
Step-by-step explanation:
Similar figures are figures which have the same shape but not the same size. This means their angle measures are equal but their side lengths are not instead they are proportional. They are related by a scale factor. To find the new side lengths of the figure multiply the original side lengths by 1/2.
The sides are 1, 2, 4, and 5.
They become:
1*1/2 = 0.5
2*1/2 = 1
4*1/2 = 2
5*1/2 = 2.5
Choose the figure with these distances.
