Answer:
Step-by-step explanation:
Given
Probability of finding oil at site 1 is 0.30
Probability of finding oil at site 2 is 0.15
Probability of finding oil at site 3 is 0.20
Probability of Finding oil at all three sites
i.e. oil is present in all three sites simultaneously

Probability of not finding oil at any of these sites
Complement of Finding oil at all three sites is equivalent to not finding the oil at all three sites
i.e.
Complement of not finding oil at any of the sites is equivalent to probability of finding oil at any of the given sites

Answer:
y= ¾x +6
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
Let's find the gradient first.

Using the formula above,

subst. the value of m into the equation.

To find c, substitute a coordinate.
When x=0, y=6,

Thus, the equation of the line is
.
Answer:
x=0, 1/4
Step-by-step explanation:
16x^2-4x=0
factor out the 4x,
4x(4x-1)=0
zero property,
4x=0, 4x-1=0,
x=0/4=0
4x=0+1
4x=1
x=1/4
65/156 = (13x5)(13x12) = 5/12
