Answer:

The median is the middle number; found by ordering all data points and picking out the one in the middle.

You want to put the numbers in order:

47, 49, 49, 50, 52, 57, 57, 57, 61

Then you go one number at a time from both ends until you get into the middle:

47, 49, 49, 50, 52, 57, 57, 57, 61

So the answer is 52.

Tip: when you do this and you are left with two numbers that are in the middle, add them and divide them by 2.

Nancy bought a mobile phone marked at $720 at a discount

m_a_m_a [10]

20% of $720( original cost)= $144 (discount)
$720- $ 144 = $576 (discounted cost)
5% tax = $36 (tax payed)
tax + cost of phone = $612 (total of both tax and discounted cost)

20% of $612=$122.40 (deposit cost?)

Drag each equation to show if it could be a correct first step to solving the equation 3(x+8)=42.

lubasha [3.4K]

Answer:

The 2nd, 3rd, and last equations could be a possible first step.

The rest are no's.

Step-by-step explanation:

In the second equation, the 3 was distributed.

In the 3rd, it was separately distributed.

In the last, both sides were divided by 3.

The rest are knows because every equation gives us enough information.

So i have 2 questions

Answer:

f of x equals negative one third x plus 5

Step-by-step explanation:

Question 1

We know the line contains the point (a,b)=(0,1) and has a slope m=0

We can find the equation of a line knowing both parameters by using

y-b=m(x-a)

y-1=0(x-0)

This is the required equation of the line

y=1

Question 2

The student is running a 5-Km race. Les's set x as the time in minutes. 3 minutes are needed to complete one Kilometer, so every single minute will be enough to run 1/3 Km. Every x minutes, the distance will be

$D=\frac{x}{3}$

Since the runner needs to complete 5 Km in total, the distance still to complete will be

$f(x)=5-D$

$f(x)=5-\frac{x}{3}=-\frac{1}{3}x+5$

This is the required function. It can be written as

"f of x equals negative one third x plus 5"
