Answer:
18. 3.3years
Step-by-step explanation:
18. 20,000 - (20,000 - .15x) = 10,000
15% of 20,000 is 3,000
Answer:
The initial distance between Wade and Alexandra is 240ft.
They walk towards each other.
Alexandra walks twice as fast as Wade.
Now, because they are walking towards each other, when the distance walked by both of them equals 240 ft, they will meet.
Then:
if Wade walks z ft, Alexandra walks 2*z ft.
So we have the equation:
Distance that Wade walked + Distance that Alexandra walked = 240ft
z + 2*z = 240ft
3*z = 240ft
z = 240ft/3 = 80ft
They will meet when Wade walks 80ft.
I think the best value for x is -9 because 6 x -9 = 54, minus 8 equals -44.
Answer:
m-9 = 3 is the required expression
Answer:
Approximate probability that 
is less than 2 = 0.1515
Step-by-step explanation:
Given -
Mean 
= 2.2
Standard deviation 
= 1.4
Sample size ( n ) = 52
Let be the mean of accidents per week at the intersection during one year (52 weeks) .
probability that is less than 2 =
= 
Putting 
= 
( Using Z table )
= 0.1515
