For the group data 4,4,6,10,13 what is the relationship between the mean and the median?

2 answers:

7 0

To find mean you first add all the numbers to get the sum of 37 then you divide the number by the amount of numbers you have so you divide 37 by 5 = 7.4.

To find median you line the numbers from least to greatest then find the number in the middle which is 6

Someone help I don't know what the diameter or radius is

Elenna [48]

<h3>Answer:</h3>

52.38 inch² & 261.90 inch²

<h3>Step-by-step explanation:</h3>

Here we need to find the area of the sector . So according to formula we know the area of sector as ,

$\boxed {\sf Area_{(sector)}= \dfrac{\theta}{360}\times \pi r^2 }$

Here we can see that the central angle subtended by the arc is 60° and the radius of the circle is 10 inches . So the required area would be ,

=> Area = ∅/ 360° × π r²

=> Area = 60°/360° × 22/7 × (10in.)²

=> Area = 1/6 * 22/7 * 100 in²

=> Area = 52 .380 in²

<h3>★ Hence the area of the red sector is 52.38 inch².</h3>

_________________________________

Now let's find out the area of blue sector .The angle subtended by the arc will be (360-60)°=300° .

=> Area = 300/360 × 22/7 × 100 in²

=> Area = 261. 90 in²

<h3>★ Hence the area of blue sector is 261.90 inch².</h3>

$\boxed{\red{\sf Area _{(red \ sector )} = 52.38 in^2 }}$

$\boxed{\blue{\sf Area _{(blue \ sector )} = 261.90 in^2 }}$

The circumference of a circle is 7 π m What is the area of the circle?

galina1969 [7]

I will find the radius first
2pi(r) = 7pi
Divide 7pi by 2pi
Hence radius is 3.5m
Now the area pi(r^2)
Pi(3.5^2)
The area of the circle is 38.48 or 49/4 pi

AREA = 49/4pi or 38.5m^2 to one d.p

Suppose you roll a special 33 sided die. What is the probability that the number rolled is a one or a two?

Pepsi [2]

Answer:

2/33

Step-by-step explanation:

Chance of rolling a 1 is 1/33, chance of rolling a 2 is also 1/33. so add the probabilities 1/33 + 1/33 =2/33

arsen [322]

Here is conversion chart

1 day=24hr

so the equation to solve this would look like this

(24*11)+7

Therefore the answer is 271 hr
