The State Education Department requires local school districts to keep these records on all students: age, race or ethnicity, da

IgorC [24]

Answer:

2.Race or Ethnicity

3.Disabilities or Special Needs

7.Current Grade Level

Step-by-step explanation:

A Categorical variable is a non numerical variable, and usually is defined as "a variable that allows to assign categories but we cannot clearly order the variables".

If a variable is not Categorical can be ordinal or or numerical.

Ordinal when we can create a order from the data. And numerical when is not categorical or ordinal.

1.Reading Test Score

False, usually the scores are quantitative or numerical variable since are measured on units..

2.Race or Ethnicity

True, is categorical variable since we don't have an order for this.

3.Disabilities or Special Needs

True, we can consider this variable as categorical since we don't have an order and can't be expressed in numerical terms.

4.Age

False, is a quantitative variable or numerical

5.Mathematics Test Score

False the scores represnt a numerical variable.

6. Days Absent

False, that can be considered as quantitative if we count the days absent

7.Current Grade Level

True. That can be considered a categorical variable since we can't express this variable with numbers.

So then the correct choices are:

2.Race or Ethnicity

3.Disabilities or Special Needs

7.Current Grade Level

PLEASEEE HELP !! What is the value of x ?

Shtirlitz [24]

Answer:

x = 20 cm

Step-by-step explanation:

The triangles given are similar triangles because they share the same angles. Because they are similar, their side lengths are in the same ratio, or proportion to one another. The left side of the larger triangle has a length of 121cm + 11cm = 132cm where the smaller triangle only has a length of 11 cm. We can put these lengths into a ratio:

$\frac{larger}{smaller}=\frac{132}{11}=\frac{12}{1}$

Since the other side of the triangle would have to be in the same proportion, or ratio, we can set up the following proportion:

$\frac{12}{1}=\frac{(5x+10)+10}{10}=\frac{5x+20}{10}$

Use cross-multiplication: 5x + 20 = (10)(12) or 5x + 20 = 120

Subtract 20 from each side: 5x + 20 - 20 = 120 - 20 or 5x = 100

Divide and solve for 'x': 5x/5 = 100/5 or x = 20 cm
