A video game company surveys a random sample of 225 of its best customer and finds that the average gamer spends $406 a year on games, with a
standard deviation of $26.
Another company is also interested in the amount game consumers spend,
and surveys a random sample of 250 gamers, over all interest levels, and
finds that the average gamer spends $250 a year on games, with a standard
deviation of $15.
Why is the second survey more believable than the first?

honeycrisps have skyrocketed to about $4.50 per pound

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
