Answer:
You can say there is no solution for a system of linear equation when the graphs are PARALLEL to each other.
ONE solution: when both lines intersect at one point
INFINITE solution: when the line goes on forever
NO solution: is when the lines are parallel to each other.
Answer:
you just need to simplify all the answers so 9 and 4 - 6 + 2 + 3 you need to keep like adding all the answers together and whatever one gets you to what it's telling you then that's the answer

Skip/ Addy had 3 green marbles
Answer:
a) 45 possible outcomes
b) 55 possible outcomes
Step-by-step explanation:
Given:
- Total cavities = 12
- Selection = 3 parts
- Non-conforming cavities = 2
Find:
a) How many samples contain exactly 1 nonconforming part?
b) How many samples contain at least 1 nonconforming part?
Solution:
- The question asks for the use of combinations to express the outcomes for each scenario.
- For first part, we want the inspector to pick exactly one non-conforming part among 3 selected. So let us say that he has already chosen that one non conforming cavity. Now he has to make 2 more selections out of total conforming cavities = 12 - 2 = 10 conforming cavities. Hence, the total possible outcome is to chose 2 randomly from 10 conforming cavities.
( Exactly 1 ) 10C2 = 45 possible outcomes
- The second part entails that at-least 1 non-conforming cavity is selected. To choose exactly 1 non conforming we calculated above. In the similar way calculate for selecting exactly 2 non-conforming cavities. The total possible outcome would be to choose from 10 conforming and we choose 1 from it:
( Exactly 2 ) 10C1 = 10 possible outcomes
- Hence, for at-least 1 non conforming cavity being selected we same the above two cases calculated:
(At-least 1 ) = ( Exactly 1 ) + ( Exactly 2 )
(At-least 1 ) = 45 + 10 = 55 possible outcomes
Answer:
333.67 miles
Step-by-step explanation:
She drives her car 91 mi on 3 gal of gas
That’s 91 mi = 3 gal
How many miles can she drive on 11 gal of gas .
Let the mile she can drive by 11 gal of gas be A
At the same rate ,
91 mi = 3 gall
A mi = 11 gal
Cross multiply
A x 3 = 91 x 11
A x 3 = 1001
Divide both sides by 3
A x 3/3 = 1001/3
A = 333.67 miles
At the same rate she’ll drive 333.67 miles on 11 gal of gas
