He equation 8 − 4x = 0 has real solution(s)

Answer:

1 real solution, x=2

Step-by-step explanation:

Let's solve for x and see how many solutions exist.

To solve for x, we must get x isolated. To do this, perform the inverse operation to both sides of the equation.

8-4x=0

4x is being subtracted from 8. The inverse, or opposite, of subtraction is addition. Add 4x to both sides.

8-4x+4x=0+4x

8=0+4x

8=4x

x is being multiplied by 4. The inverse of multiplication is division. Divide both sides by 4.

8/4=4x/4

8/4=x

2=x

x is equal to 2, therefore there is 1 real solution.

3: No

4: 25

Step-by-step explanation:

3: It won't because not everyone is the same height and there will be variation in the mean height.

4: A larger sample size will give a more accurate representation of the population, where as a sample size of 5 is much more likely to have a higher percentage of outliers, and each outlier matters much more in finding the mean. In a sample size of 25, each outlier matters much less.
