Let s represent number of shirts and h represent number of hats.
We have been given that the organizers of a talent show have budgeted $1800 to buy souvenir clothing to sell at the event. They can buy shirts for $10 each and hats for $8 each.
The cost of s shirts would be and cost of h hats would be
. The cost of s shirts and h hats should be less than or equal to 1800. We can represent this information in an inequality as:
We are also told that organizers plan to buy at least 5 times as many shirts as hats. This means that number of shirts should be greater than or equal to 5 times hats. We can represent this information in an inequality as:
Therefore, the second inequality should be and option C is the correct choice.
Answer: (a) 4
(b) 5
(c) 14
(d)
Class interval Class mark
30 - 35
35 - 40
40 - 45
45 - 50
50 - 55
Step-by-step explanation:
The data of 40 persons is given as :
Weights (in kg) Frequency
30 - 35 6
35 - 40 13
40 - 45 14
45 - 50 4
50 - 55 3
(a)
<em>Lower limit is the lowest number in a class interval .</em>
So, is the lower limit of fourth-class interval (45 - 50) is 4.
(b)
<em>Class size = Upper limit - lower limit </em>
So, Class size of first class interval = 35-30=5
Thus , class size of each interval is 5. [ class size remains same]
(c)
Highest frequency in table = 14 which is corresponding to 40 - 45 .
Thus , 40 - 45 is the class interval has the highest frequency.
(d)
<em>Class mark is the mid value of each class interval.</em>
<em>Class interval = </em>
Class interval Class mark
30 - 35
35 - 40
40 - 45
45 - 50
50 - 55
