Answer:
2
Step-by-step explanation:
2x+2=?x+13
Let x=2
2x+2=2x+13
Subtract 2x from each side
2 =13
This is never true so there is no solution
You want to isolate the variable on one side of the equation so that you can see what it's value is with respect to the other terms
Answer:
0.85% probability that the first two are good and the last three are spoiled
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which the first two jugs is not important, as is not the order in which the last three are selected. So we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
Desired outcomes:
2 spoiled, from a set of 43-11 = 32.
3 spoiled, from a set of 11.
So
Total outcomes:
5 jugs from a set of 43.
Probability:
0.85% probability that the first two are good and the last three are spoiled
