I need help on this question
My name is Ann [436]

If the weight of wrestlers on the team varies by 74 pounds, the best way to measure this would be the range.

The range indicates how much difference there is between the maximum and the minimum values, thus making it perfectly suited for finding the variance between the weights of wrestlers.

The most popular M&M color being green could be best verified by the mode.

The mode of a set is the most commonly occurring number in that set, so this would be the best way to find the most commonly occurring type of candy.

If the mean price for a download is $1.96, this could be verified by finding the mean.

The mean is the average of a data set, so this could verify that this price was the best indication of the average of the mp3 downloads.

Finally, if half the students in PE are 15 or older, this could be determined by the median.

The median is the middlemost value in a data set, so it would help you in this instance because it would allow you to see where the halfway point was in the ages of PE participants.

Hope this helps!

3 times a number is 54 less than the square of that number. Find the positive solution.
OlgaM077 [116]

Answer:x=9

Step-by-step explanation:

To find the positive solution for this, then we will say;

Let the number be x

3x<x^2-54

x^2-3x-54<0

Then we are going to factorise

x^2-9x+6x-54=0

(x^2-9x)+(6x-54)=0

x(x-9)+6(x-9)=0

(x+6)(x-9)=0

Therefore, The positive solution for this is: x=9

If x=0 and x=3 then 3 divided by 2x to the second power minus 2 divided by x to the second power minus 3x
Afina-wow [57]
Answer: undefined in both cases.


Explanation:

1) Expression to evaluate:

\frac{3}{2x^2} - \frac{2}{x^2-3x}

2) You are asked to evaluate that expression for two different cases, x = 0 and x = 3.

3) First case: x = 0

The expression cannot be evaluated at x = 0, because the denominators (both  denominators) equal 0, and the division by 0 is not defined.

So, the answer is undefined.

4) Second case, x = 3

When you replace x = 3 you get:

\frac{3}{2x^2} - \frac{2}{x^2-3x} = \frac{3}{2(3^2)} - \frac{2}{3^2-3(3)} = \frac{3}{18} - \frac{2}{9-9}

Again, this result in a division by 0, so you conclude that it is undefined too.
