i dont think this is right tho
Answer:
X probability = 0.02
Cumulative frequency at x ( 6 ) = 1
Step-by-step explanation:
X P ( X ) Cf ( X )
1 0.58 0.58
2 0.18 0.58 + 0.18 = 0.76
3 0.10 0.76 + 0.10 = 0.86
4 0.07 0.86 + 0.07 = 0.93
5 0.05 0.93 + 0.05 = 0.98
6 0.02 0.98 + 0.02 = 1
To find the number of days, divide the total swam by the average:
Days = 48 / 3.2 = 15
They swam for 15 days.
Use compound interest formula:
Future value, F
25000=P(1+i)^n
where
P=present value to be found
i=annual interest rate = 0.065
n=number of years = 6
so
25000=P(1.065)^6
=>
P=(25000/1.065^6)=$17133.353
Answer:
A=4
Step-by-step explanation:
Mariya was solving:
4x2-20x+3=0
4x2-20x=-3
A(x2-5x)=-3
At this point, we can know that 4*x2=4x2 and 4*5x=20x, son A=4
