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.
The answer is A.5 because 1/2*4=2. 2+3=5
Answer:
neither
Step-by-step explanation:
For lines to be parallels the slopes must be equal, for the lines to be perpendicular the lines have to be inverse reciprocals meaning if you have a slope of 1/2X then the perpendicular line must be -2X
Answer:
vertex:
x= 5
y= 0
coordinates: (5,0)
Step-by-step explanation:
J (Joseph) and S (Sam) together total 47. J+S=47. J (Joseph) watched 24 more than S (Sam). J=S+24 Since S+24 has the same value as J, just plug it into to J spot in the first equation (J+S=47) : S+24+S=47 so 2S+24=47 ( subtract 24 from both sides) 2S=23 (Divide both sides by 2) S=11.5 Now we can determine J by remembering that J+S=46 so J+11.5=47 (subtract 11.5) J=35.5
Joseph watched 35.5 episodes and Sam watched 11.5
