Can you explain how you would estimate the number of books sold in 1989? Number of children in six different classes are given below. Represent the data on a bar graph. Class Number of Children Fifth 135 Sixth 120 Seventh 95 Eighth 100 Ninth 90 Tenth
(a) How would you choose a scale? (b) Answer the following questions:
(i) Which class has the maximum number of children? And the minimum? (ii) Find the ratio of students of class sixth to the students of class eight.

Given info:

Number of children in six different classes are given in the attachment

Represent the data in to bar graph answer the following questions ?

Explanation:

See the above attachment

Number of children in class V = 135

Number of children in class VI = 120

Number of children in class VII = 95

Number of children in class VIII = 100

Number of children in class IX = 90

Number of children in class X = 80

Total number of children = 620

1) Scale :-

Taking scale depends upon the given values in the given data .

For convenience we take 1 cm = 10 units for related given data

On X-axis taking classes and taking on Y-axis number of children

On taking Y-axis 1 cm = 10 units

2)

Class V has maximum number of children (135)

and Class X has minimum number of children (80)

3)

Number of children in class VI = 120

Number of children in class VIII = 100

Ratio = 120:100

⇛ 120/100

⇛ 12/10

⇛ 6/5

⇛ 6:5

Answer:-

The ratio of the children on class VI to VIII = 6:5

In bar graph the width of the all bars are equal.

In bar graph the lengths of the bars Proportional to the frequency of the corresponding class.

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
