b 47
c 48 1/2
d 52
Answer: a
Which of the following numbers are integers?
2/3, 35, 0.093,-650, 42.5
a 0.093 and 42.5
b 35 and -650
c 2/3
d -650
answer: c
But I did this
To find the median of a set of numbers, you need to arrange the numbers in ascending order and then determine the middle number (or the average of the two middle numbers if the set has an even number of elements).
Arranging the set of numbers 47, 20, 52, 35, 58, 57 in ascending order:
20, 35, 47, 52, 57, 58
We can see that there are 6 numbers in the set. Since 6 is even, we need to find the average of the two middle numbers. In this case, the two middle numbers are 47 and 52. Hence, the average of 47 and 52 is (47 + 52)/2 = 99/2 = 49.5.
So, the correct answer is the closest option to 49.5, which is a. 49 1/2.
To determine which numbers in the set 2/3, 35, 0.093, -650, 42.5 are integers, you need to identify the numbers that do not have decimal or fractional parts. Integers are whole numbers that can be positive, negative, or zero.
Looking at the set, we can see that 35 and -650 are whole numbers without decimal and fractional parts. Hence, options b. 35 and -650 are the only integers in the set.
