Y = 5 - 4x
5 - 4x = x^2 - 2x - 19
0 = x^2 + 2x -24
0 = (x + 6)(x - 4)
Therefore x = -6 (Given) or 4
x = 4, y = -9
(4,-9) is the other solution
The Pythagorean Theorem states that a triangle's hypotenuse is equal to the square's of the other two sides of the triangle.
a² + b² = c<span>²
a = side of triangle
b = other side of triangle
c = hypotenuse (squared)
Find the square root to find the accurate length of the hypotenuse.</span>
30, radius is equal to half the diameter, so to get diameter from the radius, multiply the radius by two.
The coding of the statistic is used to make it easier to work with the large sunshine data set
- The mean of the sunshine is 3.05
- The standard deviation is approximately <u>18.184</u>
<u />
Reason:
The given parameters are;
The sample size, n = 3.
∑x = 947
Sample corrected sum of squares, Sₓₓ = 33,065.37
The mean and standard deviation = Required
Solution:
The mean of the daily total sunshine is therefore;
- The mean ≈ 3.05
Alternatively
,
The mean of the daily total sunshine, ≈3.05
Therefore;
Therefore;
The standard deviation, ≈ <u>18.184</u>
