Using the binomial probability relation ; the probability that an head is obtained at least 50 times is 0.0271
<u>Using the binomial probability relation</u> :
- P(x = x) = nCx * p^x * q^(n-x)
- p = probability of success = 0.4
- q = 1 - p = 0.6
- n = number of trials = 100
P(x ≥ 50) = p(x = 50) + p(x = 51) + ...+ p(x = 100)
<u>Using a binomial probability calculator</u> :
P(x ≥ 100) = 0.0271
Therefore, the probability that atleast 50 heads are obtained in the trial is 0.0271

The equation for point slope form is written as :
y - y1 =m(x-x1)
M is the slope which is given as -37
The given point would be X1 and y1, where X1 is 5 and y1 is 8.
The equation becomes:
y - 8 = -37(x -5)
#1. The answer is B, just put the points on the graphic and you will see.
#2. The answer is A, the equation explained everything.
<span>3x^2 - 4 = 7x is the standard form. To get standard form into quadratic you must have one side of the equation equal zero. The easiest way to so is subtracting 7x on both sides of the equation.
</span><span>3x^2 - 4 = 7x
-7x -7x
3x^2 -7x - 4 = 0
So, </span>3x^2 -7x - 4 = 0 is the quadratic form.
