Definition: A histogram visualises the distribution of data over a continuous interval or certain time period. Each bar in a histogram represents the tabulated frequency at each interval.
According to the given histogram,
0-20 years occur 15 times,
21-40 years occur 40 times,
41-60 years occur 40 times,
61-80 years occur 15 times.
This shows that the data is symmetrical and the majority of the attendees were between the ages of 21 and 60 (40 times).
Answer: correct choice is B.
Answer:
He will need to save $295
Step-by-step explanation:
he needs 450 and he has 155, so all you would do is subtract 155 from 450 and you get the rest he needs which is 295
Answer:
x=0 or x=2 or x=−4 or x= (7)(2)
Step-by-step explanation:
Answer: Areas = 139m²
Cost = Rs3475
Step-by-step explanation:
Area of a square wall of xm= xm².The area of the 4 walls = 4x²m²
Therefore, since the height = 6m, the other side = 6m, the area = 6x6=36m².
Area of the Four walls = 36m²x 4
= 144m². Biu the areas of the four walls excluding the door and window. Area of the door = 2m x 1m= 2m², and area of the window = 3m x 1m = 3m². Total area of the door and window = 2m² + 3m² = 5m².
Therefore, the total area of the four walls excluding the door and window = 144m² - 5m²
= 139m².
The amount required to carpeting the room will be
Let the number of square room carpeted at Rs25 which equals Rs8100 = xm²
Therefore, to know the number of square covered by this amount,= Rs8100/Rs25 = 324m²
If 324m² = Rs8100
1m² = 8100/324
139m²= 8100/324 x 139
= Rs3475
Answer:
A)
B) There are more species of plants as the number of species of birds that have been sighted in Everglades National Park is 280
Step-by-step explanation:
Total number of species of birds that migrate = 200
We are given that of all the species of birds are sighted in the park
a)Write an equation to find the number of species of birds that have been sighted in Everglades National Park.
Let y be the number of species of birds that have been sighted in Everglades National Park.
We are given that of all the species of birds are sighted in the park
So,
y=280
B)There are 600 species of plants in Everglades National Park. Are there more species of birds or plants in the park?
So, There are more species of plants as the number of species of birds that have been sighted in Everglades National Park is 280
