Using the Quadratic formula
your answer would be A and C
Answer:
(9 × 3x+7) - (5 × x+2)
Step-by-step explanation:
Red area
9 × 3x + 7
white area
5 × x+2
312* 17.5= 5460.00
134*19=2546
2546+5460= $8,006.00
6,000 because its in the thousandth and so since its a six in the thousandths its 6,000 remember the comma
Answer:
68%
Step-by-step explanation:
We observe that the mean of the sample is (61+71)/2 = 66 mph which means the standard deviation of the sample is 5 because 66-5=61 and 66+5=71. The Empirical Rule states that for data observed in a normal distribution, 68% of data will fall within one standard deviation of the mean. Therefore, approximately 68% of vehicles travel between 61 miles per hour and 71 miles per hour.
