Answer:
{ -6, -4, -2}
Step-by-step explanation:
Since x > - 8, x can be any number greater than - 8.
x = -7, -6, -5, -4,...
BUT, it can't be equal because it's not using this sign
--------------------------------------------------------------------------------
--------------------------------------------------------------------------------
1. { -10, -8, -6} can't be an inequality of x because it has -10, -8.
2.{ -8, 0, 8} can't be an inequality of x because of -8.
3.{ -9, 1, 7} can't be an inequality of x because -9 isn't greater than x.
Each of the members must raise at least $69.46.
To start they need to raise $552.50. However, they have already raised 12% of it. They only need to raise 88% of it.
552.50 x 0.88 = 486.2
Divide the remaining amount by 7 to determine how much each individual must raise.
486.2 / 7 = 69.46
Answer:
1 & 7
Step-by-step explanation:
I guessed. Good Luck!
mu = 1100 = population mean
sigma = 275 = population standard deviation
x = 1400 = raw score
z = z score
z = (x-mu)/sigma
z = (1400-1100)/(275)
z = 300/275
z = 1.0909090909091 approximately
z = 1.09
Convention is to round to two decimal places so that you can use a Z table to look up the area under the curve (which helps determine probability).
The positive z score is due to Paula's raw score being above the mean.
