Answer: A. Contractor A. The probability that both conditions are met is 0.93
Step-by-step explanation:
Probability of two independent events happening can be found by multiplying them.
Probability of A doing the job on time and on budget:
= Probability that job is done on time * Probability it is done on budget
= 0.97 * 0.96
= 0.93
Probability of B doing the job on time and on budget:
= 0.93 * 0.98
= 0.91
<em>Contractor A has the better probability at 0.93 so should be chosen. </em>
Function notation replaces the 'y' with a letter, usually 'f' and then puts the variable in parenthesis.
f(x) = 3x
Other equivalent examples would be:
g(x) = 3x
f(z) = 3z
h(a) = 3a
All of these represent the same function, just written in different forms of function notation. The variable can be represented as any letter and the function name can be different letters as well.
Answer:
2/5
Step-by-step explanation:
We can find the slope using two points
(0,0) and (5,2)
m = (y2-y1)/(x2-x1)
= (2-0)/(5-0)
= 2/5
Number 1 is 1/20 ,so number 0.5 is 1/40 of 20. so p=100/40 = 10/4 = 2.5%
so 0.5 is 2.5% of 20
proof: 2.5*20/100 =50/100 = 0.5
