Answer:
all 0.5
Step-by-step explanation:
Suppose this is a fair coin, so the chance of getting head vs tail is 50-50, or 0.5.
If you flip a coin, the chance of getting head is 0.5
If you flip a coin the 2nd time, this event is independent and unrelated to the previous result, hence the chance of getting head is still 0.5
If you flip a coin 25 times and all get head, then the chance of getting the next head is still 0.5. Because this event is still independent and not related to all the previous flips.
You answer is 6 shirts good sir. Have a nice day. :D
Can you help me please I need help with a couple of questions
Answer:
Step-by-step explanation:
<u>Equation of a line</u>
A line can be represented by an equation of the form
Where x is the independent variable, m is the slope of the line, b is the y-intercept and y is the dependent variable.
We need to find the equation of the line passing through the point (7,2) and is perpendicular to the line y=5x-2.
Two lines with slopes m1 and m2 are perpendicular if:
The given line has a slope m1=5, thus the slope of our required line is:
The equation of the line now can be expressed as:
We need to find the value of b, which can be done by using the point (7,2):
Operating:
Multiplying by 5:
Operating:
Solving for b:
The equation of the line is:
Hi,
Concept: The given problem is based on 3 Dimensional Geometry.
Consider three axes in defined space be x, y & z in their positive directions then - x , -y & -z be their negative axes.
The coordinate of given point A(x1, y1, z1) = (1, -3, 4)
If we take the reflection of point A about xz - plane x and z coordinates will remain same and y-coordinate will give its reflection. It means the value of y-coordinate will be changed which will be +ve 3.
Hence, the reflection of A(1, -3, 4) will be A'(x2, y2,z2= (1, 3, 4).
