The answer is slope is the ratio of the vertical and horizontal changes between two points on a surface or a line. The vertical change between two points is called the rise, and the horizontal change is called the run
well, we can say that 1 hour is 100%, what is 2/5 hr off of it in percentage?
A=3 b=5 c=2
x = -b +-sq root(b^2 -4*a*c) / 2a
x = [-5 +-sq root(5^2 -4*3*2)] / 6
x = [-5 +-sq root(25 -24)]/6
x = [-5 +- 1] /6
x1 = -1
x2 = -4/6 = -2/3 = -.66666666666666
Answer:
5x+40
Step-by-step explanation:
You would distribute 5 to x+8 and that would add up to 5x+40.
Answer:
P = 57/1105
P = 0.052
Step-by-step explanation:
Given:
Total number of dummy tickets = 20
Total number of tickets with value = 10 + 10 + 12 = 32
Total number of tickets in the box = 20 + 32 = 52
The probability of picking 3 tickets randomly from the box without replacement and the three are dummy (with no value) is;
P = 20/52 × 19/51 × 18/50
(As each one is picked it reduces the total number of tickets and also the number of dummy tickets by one)
P = 57/1105
P = 0.052
