Answer:

A. Enlargement

Step-by-step explanation:

We are given that,

Quadrilateral ABCD is dilated by a scale factor of 2\frac{1}{2}=\frac{5}{2}.

Now, we know that,

<h3>Dilation changes the size of the figure by the scale factor 'k'.</h3>

<em>If 'k' > 1, then the dilated figure is enlarged in size.</em>

<em>If 0 < 'k' < 1, then the dilated figure is reduced in size.</em>

Since, the given scale factor is \frac{5}{2}=2.5>1.

<h3>So, the quadrilateral ABCD is enlarged in size.</h3>

Hence, option A is correct.

Substititue 5 for x. Is the solution true?<br> 3x + 4 - x = 4x - 6
Aloiza [94]

Answer:

It's a true solution.

Step-by-step explanation:

3(5) + 4 - 5 = 4(5) - 6

15 + 4 - 5 = 20 - 6

19 - 5 = 14

14 = 14

Sav [38]

Answer:

= 7 \frac{9}{14}  \\

Step-by-step explanation:

9 \frac{1}{2}  - 1 \frac{6}{7}  \\   \frac{19}{2}  -  \frac{13}{7}  \\  \frac{133 - 26}{14}  \\  =  \frac{107}{14}  \\  = 7 \frac{9}{14}

hope this helps

Slav-nsk [51]

Answer:

Therefore, Point M( 1 , -2 ) is the Mid point of segment ST.  

Step-by-step explanation:

Given:

Let,

point S( x₁ , y₁) ≡ ( -1 , 1)  

point T( x₂ , y₂) ≡ (3 , -5)

Point M( x , y ) is the Mid point of segment ST.  

To Find:

Point M( x , y )= ?

Solution:

As Point M( x , y ) is the Mid point of segment ST.

So we have Mid Point Formula as

Mid\ pointM(x,y)=(\frac{x_{1}+x_{2} }{2}, \frac{y_{1}+y_{2} }{2})

On substituting the given values in above equation we get

M(x,y)=(\frac {-1+3}{2},\frac{-5+1}{2})\\\\M(x,y)=(\frac{2}{2},\frac{-4}{2}) \\\\M(x,y)=(1,-2)\ \textrm{which the required midpoint}

Therefore, Point M( 1 , -2 ) is the Mid point of segment ST.

Is there a difference in the amount of airborne bacteria between carpeted and uncarpeted rooms? In an experiment, seven rooms we
Annette [7]

Answer:

C. There isn't much evidence to support a conclusion that the presence of carpet is associated with an increase or decrease in the mean bacterial concentration of air.

Step-by-step explanation:

A. There are outliers in these data, so we can't rely on the two-sample t test.

There are no outliers, as the seven rooms for both sample have similar size and function.

B. This test is unreliable because the populations we're sampling from are heavily skewed.

We don't know if the populations are heavily skewed, but this effect should be appeased by the sampling.

C. There isn't much evidence to support a conclusion that the presence of carpet is associated with an increase or decrease in the mean bacterial concentration of air.

Correct conclusion, as the P-value is surely greater than the significance level (usually 0.10 at most).

D. There is fairly strong evidence to support a conclusion that the presence of carpet is associated with an increase or decrease in the mean bacterial concentration of air.

There is no evidence as the P-value is greater than the significance level.
