s2008m [1.1K]

Answer:

The answer is "0.99999340657 \sim 1".

Step-by-step explanation:

Sucess \ probability \ (p) = 94\% \ or\  0.94\\\\Sample\ numbers\ n = 14\\  

Using formula:

P(X=r)= ^n C_r \times  p^r \times  (1-p)^{n-r}

 Let

\to r=8,9,10,11,12,13 \ or\  14\\\\

Substituting the value for all r:

 P(X=8)= 0.00008540547\\\\P(X=9)= 0.00089201264\\\\P(X=10)= 0.00698743233\\\\P(X=11)= 0.03980719025\\\\P(X=12)= 0.15591149513\\\\P(X=13)= 0.37578668058\\\\P(X=14)= 0.42052319017\\

Therefore,

P(X>7)= P(X=8)+P(X=9)+....P(X=14)\\\\= 0.99999340657 \sim 1.

It would be helpful to draw the figure from the problem statement above. Drawing it, would give you a right triangle shape where the base is equal to 10 ft + 8 ft = 18 ft with the angle of 40 degrees. We use knowledge on trigonometric functions to solve this.

tan (theta) = opposite side / adjacent side

tan 40 = x / 18

x = 15.10 ft

Solve using factoring
jolli1 [7]
The equation is balanced by the 3's on both sides so that cancels out. we are left with:
x^2-6x=0
we take out an x, leaving us with:
x(x-6)=0
we know that to find the solution [ or "zero's", ] we must set "x"=0, and "x-6"=0.
the solutions are: x=0 and 6.
hope that helped, xx
