Answer:
16 tickets
Step-by-step explanation:
Number of tickets he has to sell = 25
Number of tickets he has sold = 9
How many tickets does he still need to sell?
Number of tickets he still needs to sell = Number of tickets he has to sell - Number of tickets he has sold
= 25 - 9
= 16 tickets
Number of tickets he still needs to sell = 16 tickets
Therefore, Fahad still needs to sell 16 more tickets
Answer:
and the graph would fall at a slower rate to the right
Step-by-step explanation:
we have

Observing the graph
The initial value Ao of the truck is equal to the y-coordinate of the y-intercept of the graph
so
If the depreciation rate was 15% per year, the new formula would be


----> the graph would fall at a slower rate to the right
using a graphing tool
compare the graphs
Answer:
The z-score is 
The percentile is 
Step-by-step explanation:
From the question we are told that
The data value is 0.6 standard deviations above the mean i.e 
Where
is the population mean and
is the standard deviation
Generally the z-score is mathematically represented as

=> 
=> 
The percentile is obtained from the z-table and the value is

=> 
Add 3 to both sides so that the equation becomes 2x^2 + 7x - 6 = 0.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -7 ± √(7^2 - 4(2)(-6)) ] / ( 2(2) )
x = [ -7 ± √(49 - (-48) ) ] / ( 4 )
x = [ -7 ± √(97) ] / ( 4)
x = [ -7 ± sqrt(97) ] / ( 4 )
x = -7/4 ± sqrt(97)/4
The answers are -7/4 + sqrt(97)/4 and -7/4 - sqrt(97)/4.
27-18= 9
9/18 x100= 50
There was a 50% increase in grey wolves
