Answer:

DF = 4

Step-by-step explanation:

See attachment for proper question

From the attachment, triangle DEF is an image of ABC

By comparing the position of the angles, the following sides are similar

AB to DE

AC to DF

BC to EF

By dividing the similar sides, we calculate the scale of dilation.

Scale = \frac{DE}{AB}

Scale = \frac{8}{4}

Scale = 2

To calculate DF, we make use of sides AC and DF as comparison:

Scale = \frac{DF}{AC}

Substitute 2 for Scale and 2 for AC

2= \frac{DF}{2}

Make DF the subject

DF = 2 * 2

DF = 4

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

Tanya made 75 flyers for five volunteers in her club to hang up around her school she gave 15 flyers to the first volunteer 22 f
AysviL [449]

Answer:

The remaining volunteers would get 11 flyers each.

Step-by-step explanation:

Given:

Total number of flyers = 75

Total number of volunteers = 5

Number of flyers for 1 volunteer = 15 flyers.

Number of flyers to 2nd volunteer = 22 flyers.

number of flyers to 3 volunteer = 16 flyers.

We need to find the remaining number of which are equally distributed in remaining number of volunteers.

Solution:

First we will find the number of flyers already distributed.

number of flyers already distributed is equal to sum of Number of flyers for 1 volunteer, Number of flyers for 2 volunteer and Number of flyers for 3 volunteer.

framing in equation form;

number of flyers already distributed = 15+22+16 = 53\ flyers

Number f flyers remaining is equal to Total number of flyers minus number of flyers already distributed.

Number of flyers remaining = 75-53= 22\ flyers

Number of volunteers remaining  =2

Now we will find number of flyers remaining each volunteers would get.

number of flyers remaining each volunteers would get is equal to Number of flyers remaining divided by Number of volunteers remaining.

framing in equation form we get;

number of flyers remaining each volunteers would get = \frac{22}{2}=11\ flyers

Hence the remaining volunteers would get 11 flyers each.

the total weight w in pounds of a tractor trailer capable of carrying 8 cars depends on the number of cars c on the trailer.
aliya0001 [1]
Given that t<span>he total weight w in pounds of a tractor trailer capable of carrying 8 cars depends on the number of cars c on the trailer and that the situation is represented by the function rule w = 37,000 + 4,200c

To graph the function, we draw the coordinate axis with the number of cars in the horizontal (x) axis and the weight of the truck (in thousands) in the vertical (y) axis.

The horizontal axis is calibrated starting from 0 with increment of 1 and the vertical axis is calibrated starting from 0 with the increment of 5.

From the given function rule, when c = 0 (i.e. when the truck is carrying no car) the weight of the truck is given by w = 37,000 + 4,200(0) = 37,000

Thus, the graph will start at point (0, 37).

Also when the truck is carrying 8 cars, the weight of the truck is given by w = 37,000 + 4,200(8) = 70,600

Thus, the graph will end at point (8, 70.6).
