Answer:
Solution set = {(-1,-2/5)]
Step-by-step explanation:
64p=-16+8p-40p²
64p-8p=-16-40p²
56p+16+40p²=0
40p²+56p+16=0
8(5p² +7p+2)=0
5p²+5p+2p+2=0
5p(p+1) +2(p+1)=0
(p+1)(5p+2)=0
p+1=0; 5p+2=0
p=-1; p=-2/5
Answer:
60 miles per hour
Step-by-step explanation:

Answer:
10.125
Step-by-step explanation:
Given the data :
28,45,12,34,36,45,19,20
The mean absolute deviation of the data is :
Σ|x - mean| / n
n = number of values = 8
Mean = Σx / n = 239 / 8
Mean = 29.875
Take the sum of the absolute value if the difference between each data value and the mean, then divide by the data size
Using a mean absolute deviation calculator ;
Mean absolute deviation = Σ|x - mean| / n = 10.125
