Answer:

x = 2

Step-by-step explanation:

log_525=x\\\Rightarrow 5^x=25

Taking logarithm to base 10 on both sides we get

log5^x=log25

From logarithm property

logy^x=xlogy

\Rightarrow xlog5=log25\\\Rightarrow x=\frac{log25}{log5}\\\Rightarrow x=2

\therefore x=2

Also we know that

5\times 5=25\\\Rightarrow 5^2=25

Hence, x = 2

coordinate 2 has a weight of 2, coordinate 3 has a weight of 2, and coordinate 10 has a weight of 1. Find the weighted average.
belka [17]

The weight average of the coordinates is 4

<h3>How to determine the weight average?</h3>

The given parameters are:

Coordinate 2 has a weight of 2

Coordinate 3 has a weight of 2

Coordinate 10 has a weight of 1

The weight average is then calculated as:

Weight average = Sum of (Weight * Coordinate)/Sum of Weights

So, we have:

Weight average = (2 * 2 + 3 * 2 + 10 * 1)/(2 + 2 + 1)

Evaluate the quotient

Weight average = 4

Hence, the weight average of the coordinates is 4
