Answer:Consider the Set A = {X | X is an even whole number between 0 and 2 } = .
Since, whole numbers are the set of numbers starting from zero upto infinity.
Even numbers are the numbers which are exactly divisible by '2'.
So, we have to find the even whole number between 0 and 2.
Since, only '1' is a whole number between 0 and 2 which is not an even number as '1' is not divisible by '2'.
Therefore, there is no even whole number between 0 and 2.
So, this set is empty.
Therefore, A = { X | X is an even whole number between 0 and 2} =
Step-by-step explanation:
let the first number be x
let the second number be y
x+y=203203------eqn1
x-y=3131----------eqn2
subtract eqn2 from eqn1. you'll have
2y=200072
y=100036
substitute y=100036 in eqn1, you'll have
x+(100036)=203203
x=203203-100036
x=103167
∴ x(the first number)=103167
y(the second number)=100036

Answer:
(B) 7.1 is the estimated square root of 50
Step-by-step explanation:
A. √50 = √2 √25
= 5√2.
Jaclyn did not take the square root of 2.
B. We estimate the square root of 2.
Trial and improvement:
It must lie between 1 and 2 so we try 1.5:
1.5 * 1.5 = 2.25
Its < 1.5 so try 1.4
1.4 * 1.4 = 1.96.
So it is a little above 1.4.
Try 1.45:
1.45 * 1.45
1.45
* 1.45
-------
725
5800
14500
2.1025
= 2.1025.
- this is above 2 so the answer is between 1.40 and 1.45 but closer to 1.4.
A good estimate is 1.42
So the square root of 50 is about 5*1.42 = 7.1
