Answer:
7/9
Step-by-step explanation:
P(blue) = 2:7
This means there are 2 blue parts for every 7 nonblue parts. So 9 parts total! 2:7, then, should be thought of as 2/9.
P(not blue) = 1 - 2/9
= 7/9
Think about it: there must be a total probability of 1, so the probability of <em>not</em> getting blue must be 7/9.
Answer:
Okay the question is a little unclear, but if he's only doing english, science and history the answer should be <u> 17/40</u>
Step-by-step explanation:
1/5=8/40
3/8=15/40
8/40+15/40=23/40
40/40-23/40=17/40
X=6 and y=-9. Not sure if y is correct since I kind of rushed but I hope this helps!
Answer:
(0,3) and (7,0) are solutions.
Step-by-step explanation:
In a pair of coordinates, they are always listed as (x,y). Since this is the case, you plug in each coordinate to their respective places.
For (0,3)
3(0) + 7(3) = 21
0 + 21 = 21
For (7,0)
3(7) + 7(0) = 21
21 + 0 = 21
To double check that (1,2) isn't a solution:
3(1) + 7(2) = 21
3 + 14 = 21
17 = 21 X
This doesn't work.
