If the figure is an isosceles trapezoid, then both slanted sides have the same length. 2x+2=4. That gives you 'x', and the line on top is double-x.

Answer:  The length of AB is 2 units.

Step-by-step explanation:  We are given that the trapezoid ABCD is an isosceles one, where

AB = 2x, BC = 2x + 2  and  AD = 4 units.

We are to find the length of side AB of the trapezoid.

We know that

in an isosceles trapezoid, the lengths of two non parallel sides are equal.

So, in ABCD, we have

AD=BC\\\\\Rightarrow 4=2x+2\\\\\Rightarrow 2x=2\\\\\Rightarrow x=1.

Therefore, the length of AB will be

AB=2x=2\times1=2~\textup{units}.

Thus, the length of AB is 2 units.

Which of the following rational functions is graphed below?
Zepler [3.9K]

Answer:

  D.  F(x) = 1/(x +5)²

Step-by-step explanation:

The vertical asymptote at x=-5 tells you that x=-5 will be a zero of the denominator. The only equation with a denominator factor of (x+5) is ...

  F(x) = 1/(x +5)²

_____

<em>Additional comment</em>

The fact that the value of F(x) does not change sign at the vertical asymptote tells you the denominator factor will be of even degree. That is taken for granted here, as all denominators are squares in the answer choices.

Answer:

1. Evaluate 3y - 4 for y =5

3*(5)-4=15-4=11

2. 65 + x = 99 x = ?

65+x=99

x=99-65

x=34

3. Find the product. 38.7 *21

4. Which value satisfies the equation? 9x + 3 = 30

The right value for x would be:

9x+3=30

9x=30-3

9x=27

x=27/9=3

No chi-square The principal in Exercise 7 also
larisa [96]

The random sample of the students is an illustration of sampling

The chi-square test for goodness of fit is inappropriate because the variable under study is not categorical.

<h3>How to determine the reason chi square is not appropriate?</h3>

The dataset is given as:

Monday        34

Tuesday       29

Wednesday   32

Thursday        28

Friday             19

The variable of the above dataset is a not a categorical dataset.

One of the conditions of the chi-square test for goodness of fit test is that the variable under study must be categorical.

Hence, the chi-square test for goodness of fit is inappropriate because the variable under study is not categorical.
