Find the value mean value of 5,15,25,25,45.

Step-by-step explanation:

In order to find the mean, we must add all the values together, then divide by the number of values.

1. Add the values together

2. Divide by the number of values.

Count how many values are in the set of data. There are 5 values. Divide by 5.

The mean is 23.

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
