Answer:
Answer is 3
Step-by-step explanation:
Mean of the given data=sum of all terms/total number of terms
x= 4+7+8+9+10+12+13+17/8
=80/8
=10
Mean deviation about mean
={|xi-x|/8
=24/8
=3

Answer:
1/5, 1/2, 3/4
Step-by-step explanation:
I just now this already from experience, but you could covert all of the fractions into a common denominator. For example use 20.
1/5 = 4/20
1/2 = 10/20
3/4 = 15/20
Then you just need to look at the numerators which 4,10,15 would be the order. And then make sure to convert to the original fractions making the final order be 1/5, 1/2, 3/4.
Answer= 59.8mph
So since it takes 3h of 50mph to get from Ashdown to Bridgetown Carol drives for 150miles. Because 3*50 is 150.
Then divide 60 by 70 which is 0.857. Then times 0.857 by 60 to see how long it took her , which is 51 mins. Add 3h and 51mins which gets you 3.51h.
Then add 150 and 60 to get 210. Divide 210 by 3.51 then you get 59.8 mph
F(x) = x^2 + 4x - 5
[f(a + h) - f(a)] / h
f(a) = a^2 + 4a - 5
f(a + h) = (a + h)^2 +4(a + h) - 5
= a^2 + 2ah + h^2 + 4a + 4h - 5
f(a + h) - f(a) = a^2 + 2ah + h^2 + 4a + 4h - 5 - ( a^2 + 4a - 5)
---------------- ------------------------------------------------------------
h h
= 2ah + h^2 + 4h h (2a + h + 4) 2a + h + 4
------------------- = ------------------- =
h h
