Y = mx + b
-3 = 1/2(-2) + b
-3 = -1 + b
b = -2
equation
y = 1/2x - 2
standard form
1/2x - y = 2
or
x - 2y = 4
Hello!
The mean is the average. The median is the middle number of the data set, in terms of quantity. The mode is the number that appears the most. The range is the difference between the largest and smallest numbers in the set.
Therefore, our answers are below.
Range: Difference between largest and smallest data piece.
Median: Middle value of a set of data
Mode: most commonly occurring number(s)
Mean: the sum of the data divided by the quantity of the data items.
I hope this helps!
Answer:
4.4 inches
Step-by-step explanation:
Here, we are interested in calculating the value of x.
Mathematically, a line that comes from the center of the circle and extends to a chord, divides the chord into two equal parts.
This means what we have is a right angled triangle with the radius being the hypotenuse, the half of the length of the chord as the other side of the triangle.
3.7 is half the length of the chord i.e 7.4/2
Thus;
using Pythagoras’ theorem
x^2 = 2.4^2 + 3.7^2
Pythagoras’ posited that the square of the hypotenuse is equal to the sum of the squares of the other two sides of the triangle.
Thus;
x^2 =5.76 + 13.69
x^2 = 19.45
x = √(19.45)
x = 4.41 inches which is 4.4 inches to the nearest tenth
