Answer:

The opposite of Sawyer's number must be a positive.

Step-by-step explanation:

We have been given that Sawyer picks a negative number. We are asked to tell what is true about the opposite of his number.

We know that opposite of a number means negative of a number.

Negative of a negative number would be positive: $-(-)=+$

Therefore, the opposite of Sawyer's number must be a positive.

The opposite of his negative number would be a positive number.

For example, If he picked -7, the opposite would be 7.

Excerpt from a school newspaper:

Anika [276]

A) There was no change in the number of students on honor roll from one year to the next. This is noticeable because 200/1000 = .2 just as 20%/100% = .2 or 20/100 = .2. So there never was a change!

What is the Median for the following set of numbers? â€‹21 23 76 47 55 135 45 30 17

Leno4ka [110]

Answer:

Median = 45

Step-by-step explanation:

We are given the following data set:

21, 23, 76, 47, 55, 135, 45, 30, 17

Median is the number that divides the data into two equal parts.

Formula:

$Median:\\\text{If n is odd, then}\\\\Median = \displaystyle\frac{n+1}{2}th ~term \\\\\text{If n is even, then}\\\\Median = \displaystyle\frac{\frac{n}{2}th~term + (\frac{n}{2}+1)th~term}{2}$

Sorted data:

17, 21, 23, 30, 45, 47, 55, 76, 135

Sample size = 9, which is odd

Median =

$\dfrac{9+1}{2}^{th}\text{ term} = \dfrac{10}{2}^{th}\text{ term} = 5^{th}\text{ term}\\\\= 45$

The median of given set of numbers is 45.

please help John's age increased by 11 is 5 less than 5 times his age. How old is he? If x represents John's age, which of the f

Keith_Richards [23]

So x is John's age.
We can solve this problem by working backwards.
Since it's 5 times his age, we first do 5x.
And then since it's five less, we move on to 5x - 5
And then we add the John's age is increased by 11: 5x - 5 = x + 11
I hope this helped :)
(It should be the second one you listed)
