D = {x|x is a whole number}

The given statement is true.

Step-by-step explanation:

Given sets are:

D = {x|x is a whole number}

E = {x|x is a perfect square between 1 and 9}

F = {x|x is an even number greater than or equal to 2 and less than 9}

as the sets are given in set builder notation,, we will first write the sets in set notation.

So,

D = {0,1,2,3,4,...}

E = {4,9}

F = {2,4,6,8}

Now,

EUF = {4,9} U {2,4,6,8}

= {2,4,6,8}

Hence,

The given statement is true.

Which statement is true?
Lelu [443]

Answer:

The statement that is true is:

A debt of $17 is a larger value than a debt of $20.

Step-by-step explanation:

Let us look at the statements one after the other to determine if they are true or not:

1) A debt of $17 is a larger value than a debt of $20: This is true because when measuring debts, we will consider the values in the negative sense (-). Therefore, a debt of $17 has a value of (-17) and a debt of $20 has a value of (-20). -17 is larger than - 20 on a number line, hence, a debt of $17 has a larger value for the debtor, than a debt of 20$

2) One half an apple is equivalent to 8 fourths apples:

one half an apple = \frac{1}{2}\ of\ an\ apple

8 fourths of an apple = \frac{8}{4} = \frac{2}{1}\ of\ and\ apple. Therefore, one half of an apple is not equivalent to 8 fourth of an apple.

3) 8.01 is a smaller increase in sales than 8.001: This statement is false because 8.001 is counted before 8.01, and the difference between 8.01 and 8.001 is:

8.01 - 8.001 = +0.009, hence, 8.01 is larger than 8.01 by a magnitude of 0.009

4) \frac{2}{3}\ below\ zero is a lower temperature than 6 below zero:

\frac{2}{3}\ below\ zero\ = (-\frac{2}{3})^\circ

6 below zero = - 6°

On the number line, -6 is smaller than -\frac{2}{3} hence the statement is false.

Please help me solve this :)
Svetradugi [14.3K]

In given picture we see that there are total 8 boxes out of which only 5 are shaded.

So the number that represents shaded part will be 5/8.

But we have to find which choice doesn't indicate shaded part.

So we will pick those choices which are not equivalent to 5/8.

5/8=0.625

if you convert that into percent then we get (5/8)100%=62 1/2 %

that means 5/8, 0.625, 62 1/2 % all represents same thing and represent shaded part.

So the remaining choice a) 0.582 is the final answer .
