The median is what number is the middle so list the number in order and remove 1 from each end until you get to the last number

So you get 84

Answer: 84

Work 40,75,80,80,81,    84     ,88,90,92,100,100

To start you have to order the numbers from least to greatest, getting 40, 75, 80, 80, 81, 84, 88, 90, 92, 100, 100. Then you would take out the end number on each side, getting 75, 80, 80, 81, 84, 88, 90, 92, 100. You continue taking numbers off the end until you get to the middle number, or the middle two numbers if there is an even amount of numbers, which would give you the median 84. If you had an even amount of numbers and got down to two numbers, you would add them together and divide them by two.

Method A: If we count, we see that the answer is 31.

Method B: 19 - -12 = 31. We can even do -12 - 19 and we'll get the same answer: -31, and the absolute value of -31 is 31.

Both methods will give you the same answer.

Explain in words how to find the product of -4 (-1.5) using a number line.where do you end up
Ierofanga [76]

Answer:

To multiply two minus numbers they  will result as a positive number.

the product of any numbers when there is a negtive will always have 2 negtives invlved form three numbers including the answer.

-4 x -1.5 is the same as 4 x 1.5

the answer is  6

Three numbers like -1 x  4 will also be 2 numbers of negative.

= -4

We change this to -4 x 1.5 and shows the answer as -6

But the question had 2 negative numbers already and the answer is just positive 6.

Find the difference using the number line!!!!!!!!!!!!! Help
Rzqust [24]

The correct answer is 7.2

We can subtract 2 from 4, which is 2.

They're both in the same decimal place, so that is why they are affecting each-other.

Help me solve this please

Answer:

D'G' = 52.5 units

Step-by-step explanation:

Since the dilatation is centred at the origin then multiply the original coordinates by the scale factor 3.5

D' = (1 × 3.5, 7 × 3.5 ) = (3.5, 24.5 )

G' = (- 8 × 3.5, - 5 × 3.5 ) = (- 28, - 17.5 )

Calculate D'G' using the distance formula

d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = D' (3.5, 24.5) and (x₂, y₂ ) = G' (- 28, - 17.5)

D'G' = \sqrt{(-28-3.5)^2+(-17.5-24.5)^2}

       = \sqrt{(-31.5)^2+42^2}

       = \sqrt{992.25+1764}

        = \sqrt{2756.25}

         = 52.5 units
