<u>Answer:</u>
The correct answer option is B. equal.
<u>Step-by-step explanation:</u>
In a symmetrical distribution the mean, median, and mode are equal.
In any distribution which is symmetric, half of its curve is the mirror image of the other half. The pull remains same on each side and the frequencies are also symmetrically distributed.
Therefore, mean, median and mode all fall at the middle as one side balances the other sides.
A certain number (x) is 3 more then 5 times another number (y)
x = 5y + 3
the difference of the 2 numbers is 11
x - y = 11
so ur system of equations is :
x = 5y + 3
x - y = 11
If the two pieces are X and Y, and one is X feet then to find the other just subtract X from the total. it would be Y = 9 - X
The images of the lines are perpendicular to each other
Answer:
The probability of the type I error is 1 %
Step-by-step explanation:
From the given statement we as a professor work to catch student . He ensure view of all student and even a video recording of the exam.He estimates that he catches 95% of student who cheat in his class. 1% of the time he accuses a student of cheating he is actually incorrect.Hence the probability of Type I error is 1 %.
