The mean of four number is 14.if two numbers, x and x + 2 are added to the set of data, the new mean is 15.calculate the value of x

Step-by-step explanation:

Mean = Total ÷ Number of Data

Total = 14 × 4 = 56

Total after = 15 × 6 = 90

Difference = 90 - 56 = 34

Hence,

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
