The some of all even numbers that are small than 100
the average of all even numbers that are smaller than 1000 is
Find the sum of all prime numbers between 1 and 100 that are simultaneosly 1 greater than multiple of 4 and 1 less than a multiple of 5
The sum of all natural numbers that are smaller than 500 and divisible by 5 is ............
Dịch:Tổng của tất cả các số tự nhiên nhỏ hơn 500 và chia hết cho 5 là bao nhiêu?
Số các số nhỏ hơn 500 và chia hết cho 5 là:
( 495 - 0 ) : 5 + 1 = 100 (số)
Tổn của các số tự nhiên nhỏ hơn 500 và chia hết cho 5 là:
( 495 + 0 ) x 100 : 2 = 24750
Đ/S: 24750
We have :
6 ; 7 ; 8 ; ... ; 499.
Count the number of rows Rating:
( 499 - 6 ) : 1 + 1 = 494
Thus, the total of the range are:
( 499 + 6 ) x 494 : 2 = 124 735.
Answer : 124 735.
số lượng số hạng là:(495-5):5+1=99(số)
tỏng là:(495+5)*99 : 2=24750(số)

Bài làm.
Some of the terms are:
(495-0):5+1=100(number)
The sum of all the number:
(495+1).100:2=24800.
Fin the sum of all natural numbers that are smaller than 500 and divisible by 5 is 24800.
Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions.
Animals have an intuitive awareness of quantities. They know without analysis the difference between a number of objects and a smaller number. In his book "The Natural History of Selboure" (1786), the naturalist Gilbert White tells how he surreptitiously removed one egg a day from a plover's nest, and how the mother laid another egg each day to make up for the missing one. He noted that other species of birds ignore the absence of a single egg but abandon their nest if more than one egg has been removed. It has also been noted by naturalists that a certain type of wasp always provides five - never four, never six - caterpillars for each of their eggs so that their young have something to eat when the eggs hatch. Research has also shown that both mice and pigeons can be taught to distinguish between odd and even numbers of food pieces.
These and similar accounts have led some people to infer that creatures other than humans can actually count. They also point to dogs that have been taught to respond to numerical questions with the correct number of banks, or to horses that seem to solve arithmetic problems by stomping their hooves the proper number of times.
Animals respond to quantities only when they are connected to survival as a species - as in the case of the eggs - or survival as individuals - as in the case of food. There is no transfer to other situations of from concrete reality to the abstract notion of numbers. Animals can "count" only when the objects are present and only when the numbers involved are small - not more than seven or eight. In lab experiments, animals trained to "count" one kind of object were unable to count any other type. The object, not the numbers, are what interest them. Animals' admittedly remarkable achievements simply do not amount to evidence of counting, nor do they reveal more than innate instincts, refined by the genes of successive generations, or the results of clever, careful conditioning by trainers.
The author mentions that all of the following are aware of quantities in some ways EXCEPT ________.
A. caterpillars
B. mice
C. plovers
D. wasps
