How do you find the median of a class?

Answers

Answer 1

In a grouped data,

it is not possible to find the median for the given observation by looking at the cumulative frequencies.

The middle value of the given data will be in some class interval. So, it is necessary to find the value inside the class interval that divides the whole distribution into two halves.

In this scenario, we have to find the median class.

To find the median class, we have to find the cumulative frequencies of all the classes and n/2.

After that, locate the class whose cumulative frequency is greater than (nearest to) n/2. The class is called the median class.

After finding the median class, use the below formula to find the median value.

[tex]Median = l +(\frac{\frac{n}{2}- cf}{f} )*h[/tex]

Where

l is the lower limit of the median class

n is the number of observations

f is the frequency of median class

h is the class size

cf is the cumulative frequency of class preceding the median class.

Amy buy 6 tickets for a match, 3 adult and 3 children tickets. Each ticket costs £7.27. She gets £2.75 off on each children's ticket. How much does Amy finally pay for 6 tickets?

Answers

Answer:

$35.37

Step-by-step explanation:

Answer:

Amy pays £35.37 for 6 tickets

Step-by-step explanation:

since each ticket costs the same amount, we can do 6(£7.27) to find out how much she originally had to pay before she gets £2.75 off on each children's ticket

6(£7.27)=£43.62

now, since she gets £2.75 off on each children's ticket, and there are three children, to find out how much money she got off total:

3(£2.75)=£8.25

finally, we have to subtract £43.62-£8.25 to find the total amount Amy finally pays for 6 tickets

£43.62-£8.25=£35.37

so, Amy pays £35.37 for 6 tickets

m∠MYX =?? degrees


° m∠ZMW =?? degrees

Answers

Answer:

<ZMW =90

<MYX = 29

Step-by-step explanation:

Remark

A Rhombus has a lot of peculiar properties. One of them is that the diagonals intersect at right angles. That means <ZMW =90 degrees.

Since the angle XMY = 90 degrees, it follows that <MXY + <MYX = 90 degrees because the third angle of the triangle = 90.

<MXY = 61 is given

So 61 + <MYX = 90                Subtract 61 from both sides.

<MYX = 90 - 61

<MYX = 29

m<MYX=29°

m<ZMW=90 diagonal bisect each other perpendicularly

Step-by-step explanation:

m<MYX+m<MXY+m<XMY=180 sum of interior angle of the triangle

here

m<XMY=90° diagonal bisect each other perpendicularly

m<MYX+61°+90°=180

m<MYX=180-151=29°

What is Arithmetic sequence?

An arithmetic sequence is the sequence of numbers where each consecutive numbers have same difference.

We have to given that;

The sequence is,

⇒ 2, 7, 12, ...

Now, We can find the common difference as;

The sequence is,

⇒ 2, 7, 12, ...

Common difference = 7 - 2 = 5

Common difference = 12 - 7 = 5

Hence, It is an Arithmetic sequence.

The owner of a snow cone stand used (1)/(4)gallon of syrup o make 16cherry snow cones . She used the same amount of syrup in each snow cone how much syrup in gallons was used in each cherry snow cone

Answers

Answer:

1 /64 gallon.

Step-by-step explanation:

Number of cherry snow cones made from 1/4 gallons of syrup = 16

If the same amount of syrup is used in each cherry snow cone ;

Amount of syrup used in each cherry snow cone would be :

Gallons of syrup used / number of cherry snow cones made

= 1/4 gallons ÷ 16

= 1/4 * 1/16

= 1 / 64 gallons

For Each cheery snow cone, 1/64 gallon of syrup was used.

You purchase a bond with a coupon rate of 8.5% and par value of $2,000. The value of the bond rose to $2,500. What is the bond?

Answers

Answer:

The bond yield is 6.80%.

Step-by-step explanation:

Note: This question is not complete. The complete question is therefore provided before answering the question as follows:

You purchase a bond with a coupon rate of 8.5% and par value of $2,000. The value of the bond rose to $2,500. What is the bond yield?

The bond can now be calculated as follows:

Coupon payment = Coupon rate * Bond per value = 8.5% * $2,000 = $170

Bond yield = Coupon payment / Current value of the bond = $170 / $2,500 = 0.068, or 6.80%

Therefore, the bond yield is 6.80%.
