What is the difference between the mean and the median of the following distribution?

2 answers:

8 0

The definition of mean, is to add up all the numbers and divide it by how many numbers there are. So, in this case the mean would be 1+1+1+2+2+2+2+3+3+4+4+4+4+5+5+6+7+7+8+8+9 = 86. You would then take 86 and divide that by 21, and you would get 4.0
The definition of median states to find the middle of the numbers. So the median would be 4.
So you would just take 4 - 4 = 0.

0 would be correct.

He minimum and maximum temperature for a day in cupcake town can be modeled by the equation below: 3|x − 8| + 15 = 18 what are t

ASHA 777 [7]

First, put the modulus equation on one side with everything else on the other side.

3|x-8|=18-15
|x-8| = 3/3
|x-8| = 1
x-8 = +- 1

x-8 =1
x= 9

AND

x-8=-1
x=7

The minimum temperature would be 7° and maximum would be 9°.

Hope I helped :)

Answer:

liam

Step-by-step explanation:

We have, 25% × x = 150

or,

100

× x = 150

Multiplying both sides by 100 and dividing both sides by 25,

we have x = 150 ×

100

x = 600

If you are using a calculator, simply enter 150×100÷25, which will give you the answer.

The equation of a circle is ( x - 3) 2 + ( y + 2) 2 = 25. The point (8, -2) is on the circle.

Shtirlitz [24]

Answer:

x =8 is the equation of the tangent.

Step-by-step explanation:

Here the equation of the given circle is: $(x-3)^{2} + (y+2)^{2} = 25$

Now, comparing it with the general equation of circle: $(x-h)^{2} + (y -k)^{2} = r^2$

we get the central coordinates (h,k) = (3,-2)

So, the slope of the line joining center and (8, -2) = $\frac{-2 -(-2)}{8-3} = \frac{0}{5} = 0$

Since the slope of line = 0, line is parallel to x axis.

Now, as tangent and the line is perpendicular to each other

⇒Slope of the tangent = -1/ slope of the line = $\frac{-1}{0}$

Now, by point slope formula: the equation of the tangent is

(y-y0) = m (x-x0)

or, $(y +2) = \frac{-1}{0} (x -8)$

or x =8 is the equation of the tangent.

Answer:

$28

Step-by-step explanation:

Time = 4 hours

Charge = $7 / hour

Multiply those two numbers:

4 hour × $7 / hour = $28

Function f(time) = $7 × time

Identify all the sets to which the number belongs choose from rational number whole number or integer 1.256 I think irrational c

VLD [36.1K]

Answer:

Rational

Step-by-step explanation:

1.256 is not a whole #, and it's also not an integer. An integer is basically whole #s and their opposites. The # is not irrational. 1.256 is a terminating decimal, and can be turned into a fraction. 1.256 = 1 32/125.
