It's a conditional probability: (We know that the probability of getting 1 tail or 1 head is equal to 1/2)
Probability ( Tail AND Tail) = 1/2 x 1/2 = 1/4
1,450 because you would plug 75 in for x
f(x)= 20(75)-50
Can be 40/100 but when you simplify it will give you 4/10 give me thanks if it helps!!! I hope it did;))))
Do pemdas and once you got your answer from that keep checking
Answer:
Option a) A line joining points, does not describe the slope.
Step-by-step explanation:
Slope of a line:
- Slope is calculated by finding the ratio of the vertical change to the horizontal change between two distinct points on a line.
- It is defined as the change in the y coordinate divided by the corresponding change in the x coordinate, between two distinct points on the line.
- Slope of a line is a number that describes both the direction and the steepness of the line.
- Slope gives the constant rate of change or a measure of change between two points.
Hence, from the given options slope is not a line segment joining two points but it is the change in the line segment between two points.
Hence, option a) A line joining points, does not describe the slope.
