Answer: 0.7
Step-by-step explanation:
p(tail) + p(head) = 1
p(tail) = 1 - p(head)
p(tail) = 1 -0.3
p(tail) = 0.7

Rewrite the equation in slope intercept form.
First add 2x to both sides:
5y = 2x + 20
Divide both sides by 5
y = (2/5)x + 4
Based on this equation, the y-intercept is 4, which is true for the graph. The slope is 2/5, which is also true for the graph, seeing as how there are points at (-5,2), (0,4), and (5,6). Between each point you go 2 up and 5 to the right.
Answer:
{x,y} = {2,-2}
Step-by-step explanation:
System of Linear Equations entered :
[1] 7x + 3y = 8
[2] 3x - 4y = 14
Graphic Representation of the Equations :
3y + 7x = 8 -4y + 3x = 14
Solve by Substitution :
// Solve equation [2] for the variable x
[2] 3x = 4y + 14
[2] x = 4y/3 + 14/3
// Plug this in for variable x in equation [1]
[1] 7•(4y/3+14/3) + 3y = 8
[1] 37y/3 = -74/3
[1] 37y = -74
// Solve equation [1] for the variable y
[1] 37y = - 74
[1] y = - 2
// By now we know this much :
x = 4y/3+14/3
y = -2
// Use the y value to solve for x
x = (4/3)(-2)+14/3 = 2
Solution :
{x,y} = {2,-2}
Answer:
Step-by-step explanation:
p^2+14p-48
p^2-6p+8p-48
p(p-6)+8(p-6)
(p-6)(p+8)
p-6=0 ,p+8=0
p=6 ,p=-8
Answer:
You can use the ASA Postulate to prove the Angle-Angle-Side Congruence Theorem. A flow proof is shown below. If two angles and a nonincluded side of one triangle are congruent to two angles and the corresponding nonincluded side of another triangle, then the triangles are congruent.
