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
(rounded up)
<span> </span>
3*3 = 9
2*6 = 12
1*1 = 1
9+12+1 = 22
The Giants would score 22 points if Tom is correct
6.4 ounces.
You can get this by first converting to ounces which is a smaller value. Then you can divide by 10.
The focus is left of the vertex, so the parabola opens to the left. The vertex is halfway between the focus and directrix, so the directrix is the vertical line
x = 2
