Answer:

let the number of steps taken by friend 1, 2 and 3 be: x, y and z respectively

we know that the mean of the total steps taken by all the friends is 10,350

Since the formula for mean is: sum of all values / number of values

here, the total values is the total number of steps taken

So,

steps taken by friend 1 +steps taken by friend 2 +steps taken by friend 3 +steps taken by friend 4 +steps taken by friend 5 +steps taken by friend 6

all that divided by 6 will give us the mean

so, 7800 + 8000 + 9800 + x + y + z / 6

(25600 + x + y + z)/6 = 10350

25600 + x + y + z = 10350 * 6

x + y + z = 62100 - 25600

x + y + z = 36500

So since the sum of x, y and z is 36500,

we can say that the average value of x , y and z is 12167 (36500/3)

So the next thing to make an equation out of is Median

to find the median, we need to arrange the values in any order you like, i will arrange in descending order

so since the estimated value of all x , y and z is greater than the greatest known value:

x > y > z > 9800 > 8000 > 7800

Since this set of values has an even number of values, we will take the average of the middle 2 values as the median

(9800 + z)/2 = 10000

9800 + z = 20000

z = 10200 -------- we have found one of the three values! getting closer

Now, the final equation will be found from the range

since we already have sorted our data, and the difference of the highest and lowest is the range

x > y > z > 9800 > 8000 > 7800

So, x - 7800 = 7500

x = 15300 ------- now that we have x and z, we can use the first equation to find the value of y and we will be done!

x + y + z = 36500

replacing the values

15300 + y + 10200 = 62100

y = 36500 - 25500

y = 11000

So the three remaining friends walked

15300, 11000 and 10200 steps

Ann [662]

Corrected Question

In the year 2009, the cost of a flat screen television can be modeled by the equation C = -10t^2 + 500 where t is the number of years since 2009. Factor this cost polynomial.

Answer:

$C=10(50-t^2)$

Using express exponents, you write C=10(50-t^2)

Step-by-step explanation:

To factor the cost polynomial, $C=-10t^2+500$ , we follow these steps.

Step 1: Determine the greatest common divisor of the terms in the polynomial

The terms in the polynomial are $-10t^2$ and 500$

The greatest common divisor of $-10t^2$ and 500$ is 10.

Step 2: Factor the polynomial by dividing each of the terms with the greatest common divisor obtained above.

$C=10\left(\dfrac{-10t^2}{10} +\dfrac{500}{10}\right)\\C=10(-t^2+50)\\$We can rewrite this as \\C=10(50-t^2)$

Nikolay [14]

Answer:

Describe the translation you performed on the original triangle. Use details and coordinates to explain how the figure was transformed, including the translation rule you applied to your triangle. I translated my original figure 11 units to the left and 3 units up. The translation rule was (x, y) -> (x+11, y+3).
