1: -5 = 3m + c
2: -2 = 0 + c
From equation 2, we knew c = -2
So we sub into equation 1 and got the value of m
-5 = 3m - 2
m = -1
The equation of line is y = -x - 2
Answer:
6x -5y
Step-by-step explanation:
saw it on the picture on there
V = 4/3πr^3V = 4/3 (π) (6.5)^3
V = 366.1666π (6 repeat)
answer is 366.16 π (3rd choice)
Answer:
That probability is 0.1838 or 18.4% or enter 18.4
Step-by-step explanation:
mean 35 sd 5
20 is 3 sd s to the left of the mean
30 is 1 sd to the left.
The empirical rule has 68% within 1 sd or 34% on one side
It has 95% within 2 sd or 47.5% on one side
It has 99.7% within 3 sd or 49.85% on one side
Therefore between 3 sd and 1 sd on one side is 49.85-34=15.85% or enter 15.9
mean of 48 sd 7
between 48 and 55 is between -1 and 0 sd or 34% enter 34. The last one doesn't seem to post easily:z=(x-mean)/sd or z< (1217-1481)/293 or z <-264/293 or -0.901,
That probability is 0.1838 or 18.4% or enter 18.4
