Sure. The point is ON the line of reflection.
Answer:
The answer is "between 60 and 96 jobs per day".
Step-by-step explanation:
In this solution, there is a mound-sized and symmetrical distribution for the number of works submitted to your computer per day with mean=78, and standard deviation=6.
Therefore a distribution of 95% decreases between the average
3* standard deviation
Therefore,
![\to 78\pm (3*6)=(78-18, 78+18)=(60,96)](https://tex.z-dn.net/?f=%5Cto%2078%5Cpm%20%283%2A6%29%3D%2878-18%2C%2078%2B18%29%3D%2860%2C96%29)
The 95% distribution falls in between 60 and 96 jobs per day.
43 × 15 = 645.
First, set up the long multiplication.
Second, calculate 3 × 5, which is 15. Since 15 is two-digit, carry the first digit 1 to the next column.
Third, calculate 4 × 5 which is 20. Since 21 is two-digit, carry the first digit 2 to the next column.
Fourth, bring down the carry digit of 2.
Fifth, calculate 3 × 1, which is 3.
Sixth, calculate 4 × 1, which is 4.
Seventh, calculate 215 + 430, which is 645.
Eighth, therefore, 43 × 15 = 645.
Or.. an easier way is to use a calculator. They always come in handy when doing multiplication.
765
you divide the 2 boards by half so now you know one board is 153 and multiple that by 5 and get 765
