30 divided by 2 = 15. then 15 multiply by 176 = 2,640. so, your ans is 2,640 (A).
Answer:
11x+2y+21 x = 15
2x+3y+6z = -29
13x+9x+2x =22
Step-by-step explanation:
This is an augmented matrix
It is the coefficients of the variables and the last number is the constant
11x+2y+21 x = 15
2x+3y+6z = -29
13x+9x+2x =22
Answer:
We know that the total area under the normal curve is 100%. According to the empirical rule of Normal distribution:
Approximately, 68% of data lies within
standard deviations of mean.
Approximately, 95% of data lies within
standard deviations of mean.
Approximately, 99.7% of data lies with
standard deviations of mean,
Therefore, in a normal curve, roughly 95% of all cases fall within plus or minus two standard deviations.
