Answer:
19
Step-by-step explanation:
1447-3=1444, 1444/76=19
Hope that helps!
First, you have to represent each given set by listing their elements. Observe:
• D = {x | x is a whole number}
D = <span>ℤ
</span>D = {..., – 3, – 2, – 1, 0, 1, 2, 3, ...}
• E = {x | x is a perfect square between 1 and 9}
("between" does not include the boundaries)
E = {x | x is a perfect square, 1 < x < 9}
E = {x | x = k², k ∈ ℕ and 1 < x < 9}
E = {2²}
E = {4}
• F = {x | x is an even number, 2 ≤ x < 9}
F = {2, 4, 6, 8}
So,
D ∩ F
= {..., – 3, – 2, – 1, 0, 1, 2, 3, ...} <span>∩ {2, 4, 6, 8}
</span>
= {2, 4, 6, 8} ≠ {4, 6}
Therefore, that statement is false.
I hope this helps. =)
I think it’s the third option but ion know
Answer: 1.1
Step-by-step explanation: 1.083, if rounding to one decimal place look at the next digit, so in this case the 8. If the digit is 5 or higher, round the tenth up. If the number is 4 or below, round down. So you will end up with 1.1
