The mean is the sum of all 12 numbers divided by 12, which is 578.25 ~ 578.3. The variance is calculated by subtracting each score from the mean, squaring, and adding all such squares. Then divide by the number of terms (12) to get 68572.35. Take the square root to get the standard deviation, which is 261.9. So the correct answer is B.

Write the equation of a line that is
il63 [147K]

Answer:

Y= 3x-7

Step-by-step explanation:

Since the line is parallel , the slope is same i.e. 3 .

now the equation should be y= Mx + b where m is the slope and c is the y-intercept

plugging the value of m=3 and ( 3,2) into the equation

2= 3(3) + c

2= 9+ c

c= -7

hence the equation of the line is y=3x-7
