Angelique says finding the absolute value of a number is as same as finding the opposite of the number. For example, |-5 | = 5.

Explain her error.*

Her error is that the outcome of an absolute number can NEVER be negative. For example, if it was | 1 | it would NOT be equal to -1. It would still be 1. However, if it was | -1 | the answer would be 1. The outcome always has to be a positive number. Hope this helps have a great day!

Answer:

Step-by-step explanation:

<em>The aboslute value of a number is how far it is from zero, so the answer can never be a negative number.</em> The <em>absolute value of negative five is positive five. </em>The <em>absolute value of positive five is postive five.</em> If <em>Angelique</em> was to do the <em>opposite value of positive five, she would answer negantive five, which is incorrect.</em>

Hope this helps!

Ali surveyed 200 students at a school and recorded the eye color and the gender of each student. of the 80 male students who wer
Aloiza [94]
Total number of students surveyed = 200
Number of male students = 80
Number of female students = 200 - 80 = 120

Number of brown eyed male students = 60
Probability of a brown eyed male student = 60 / 80 = 0.75.

Since, <span>eye color and gender are independent, this means that eye color is not affected by the gender. Thus, we expect a similar probability of brown eye for female as we had for male.

Let the number expected of brown eyed females be x, then x / 120 = 0.75.

Thus, x = 120(0.75) = 90.

Therefore, the number female students surveyed expected to be brown eyed is 90.</span>

Write an example of the associative property of addition
vfiekz [6]
The word "associative" comes from "associate" or "group";the Associative Property is the rule that refers to grouping. For addition, the rule is "<span>a + (b + c) = (a + b) + c</span><span>"; in numbers, this means 
</span>2 + (3 + 4) = (2 + 3) + 4. For multiplication, the rule is "<span>a(bc) = (ab)c</span>"; in numbers, this means2(3×4) = (2×3)4<span>. Any time they refer to the Associative Property, they want you to regroup things; any time a computation depends on things being regrouped, they want you to say that the computation uses the Associative Property.</span>
