Answer:
y = -3x - 5
Step-by-step explanation:
First find the slope: (-20 - 1) / (5 - (-2)) = -3
Then plug in one set of points into the equation y = mx + b.
1 = -3(-2) + b
1 = 6 + b
b = -5
So you can get the equation: y = -3x - 5
Answer:
y=mx+b
Step-by-step explanation:
1954 to 2015 = 61 years
310,000 = x*(1.22)^61
where x i original price

Answer:
- The mean length of 10 children's big finger is 8.1 cm
Average length of all the 10 children's finger is (8.1×10) cm = 81 cm.
- The mean length of 11 adult's big finger is 14.1 cm
Average length of all the 11 adult's big finger is (14.1×11) cm =155.1
- Mean length of these 21 people's big finger is

- Hence, <em><u>11.24</u></em> is the right answer.
40! / 30! = 40*39*38*37*36*35*34*33*32*31
dividing this by 10! 10*9*8*7*6*5*4*3*2*1
= 4*13*19*37*17*11*4*31
= 847,660,528
