First u add ten to both sides to cancel out. Now you have 14=-7s. Since you are trying to do the opposite operation, you divide by -7 on each Sides. Now you have -2=s. Hope this helped
Answer:
Midpoint = (-3, 4.25)
Step-by-step explanation:
Answer:
The outcome of guessing the correct answers to a 50 question test is 12.5.
Step-by-step explanation:
Let us first consider one question.
Since it has 4 options so we can say that;
Total number of possible outcomes = 4
Since 1 answer is correct so we can say that;
Favorable outcome = 1
Now we can say that;
Probability for choosing correct answer can be calculated by Favorable outcome divided by Total number of possible outcomes.
framing in equation form we get;
Now Given:
Total number of question = 50
So we can say that;
Total number of correct answer out of 50 is equal to Probability for choosing correct answer multiplied by Total number of question.
framing in equation form we get;
Guessing number of correct answer out of 50 =
Hence The outcome of guessing the correct answers to a 50 question test is 12.5.
