D, because of the arrows going both directions, you know part of it,

and then you just have to put in the values from the number line. The first arrow ends at zero with a bracket, and brackets mean the number is included. So now you have,
( - infinity, 0] ( x, infinity)
Then, your last value is at 1/2 with a parentheses, indicating it is not included. So, your final answer would be,
( - infinity, 0] ( 1/2 , infinity)
{infinity is always written with a parentheses in domain}
Answer:
5 friends with money left over
Step-by-step explanation:
30/4=7.5
30-8=22
22/4=5.5
So therefore they can bring 5 friends with money left over
In the year 2008 and 2009, the company had profit 2.5 thousand dollars and 1.75 thousand dollars consecutively
In the year 2010 and 2011, the company experienced a loss of 3.3 thousand dollars and 1.4 thousand dollars.
Total profit is 2.5 + 1.75 = 4.55 thousand dollars
Total loss = 3.3 + 1.4 = 4.7 thousand dollars
Total loss is bigger than the total profit so the company needs to make profit in 2012 to break even = 4.7 - 4.55 = 0.37 thousand dollars (this is the least profit the company needs to make)
Answer:
C. 1/9
Step-by-step explanation:
Assuming the selections are independent, their joint probability is the product of the probabilities of the individual events.
P(pink square) = (# pink squares)/(# squares) = 16/60 = 4/15
P(red or blue round) = (#red or blue rounds)/(# rounds) = 15/36
Then the joint probability is ...
P(defined event) = (4/15)(15/36) = 4/36 = 1/9
Look at the picture.
ΔABD and ΔBCD are similar, therefore:

Use Pythagorean theorem:
