To answer problems like this you have to use binomial:
P (x > 1) = 1 – p (0
< x < 1) > .7
So:
1 – p (0) – p (1) >
.7
1 – (3/ 4) ^n – (3/ 4)
^n (n – 1 ) (1/ 4) > .7
Therefore n > 5.185,
and the smallest value of n so that we can satisfy the given condition is 6

Answer:
1/5
Step-by-step explanation:
In order to find the answer, we need to isolate the "n."
Get 5 to the other side by dividing both sides by 5
(n-1/10)= 1/2 ÷(5)
Multiply the 2 and the 5 of the equation.
(n-1/10)= 1/10
Next, move the fraction on the left side, to the right.
n= 2/10
Reduce.
n= 1/5
Answer: the answer is y=-22x+86
here is why:
the slope is -22 which is the m --> y=mx+b the point is (4,-2) the x=4 and y= =2
If we set up the equation:
-2= -22(4)+86
-2= -88+86
-2= -2
Answer:
I and IV
Step-by-step explanation:
Since 1-sin(θ)² = cos(θ)², the given equation is equivalent to ...
√(cos(θ)²) = |cos(θ)| = cos(θ)
This will be true where the cosine is non-negative, in the first and fourth quadrants.
Answer:
Total Sold potatoes =213
Paid price=213*0.47=100.11
Sold price=213*0.88=187.44
Lost potatoes=2.82
=187.44-100.11-2.82
Profit =84.51
