Which sequence of transformations proves that shape I is similar to shape II?
Serhud [2]

Answer:

B. a reflection across X axis and then a dilation by a scale factor of 1.5

Step-by-step explanation:

As clear from the graph all the coordinates of image 2 are 1.5 times of image 1 so shape 2 is dilated by the scale factor 1.5.

It is evident from the graph that lines AO and A"O"are parallel to each other so shape 2 is the reflection of shape 1.

Now we calculate the magnitude of line AB

m1 = (y2-y1)/(x2-x1)

    =(-3+6)/(-4.5=9)

    =3/4.5

    =1/1.5

    =2/3

Next we calculate magnitude m2 of A"B"  

m2= (2-4) /(-3+6)

     =(-2/3)

Then we know Tan(180-∅) = -tan∅

similarly if m1=(-m2)

then the one line having magnitude m2 is the rotated image through X axis by 180° of the line having magnitude m1.

So the answer is B.

sergejj [24]

Answer:

Following are the solution to the given question:

Step-by-step explanation:

H_0: Management quality and corporate reputation are independent.  

H_1:  Management quality and corporate reputation are not independent.

Test statistic:

\to \chi^2 = \frac{\sum (O-E)^2}{E}

= 0.71429 + 0.0102 +2.8809+0.625+1.75 +0.3333    +0+3.2143+7.5\\\\= 17.02806

The critical \chi^2 fordf = (r-1)(c-1) = (3-1)(3-1)= 4 and \alpha = 0.05 is \chi^2= 9.4877

Test statistic:

17.02806 > 9.4877 therefore rejecting the null hypothesis H_0.

p-value= 0.001909

Interpretation:

There is no internal governance quality as well as the reputation of the organization.

A man has 32 coins in his pocket, all of which are dimes and quarters. If the total value of his change is 545 cents, how many d
inn [45]

A dime is worth 10 cents and a quarter is worth 25 cents.

Let D be the number of dimes and Q be the number of quarters.

Since the total amount of coins in the pocket is 32, then:

D+Q=32

On the other hand, the total value of D dimes is 10D, while the total value of Q dimes is 25Q. Then, the total value of D dimes and Q cuarters is 10D+25Q, which must be equal to 545. Then:

10D+25Q=545

Notice that we have found a 2x2 system of equations:

\begin{gathered} D+Q=32 \\ 10D+25Q=545 \end{gathered}

Solve the system using the substitution method. To do so, isolate D from the first equation and replace the expression for D into the second equation to obtain a single equation in terms of Q:

\begin{gathered} D+Q=32 \\ \Rightarrow D=32-Q \\  \\ 10D+25Q=545 \\ \Rightarrow10(32-Q)+25Q=545 \\ \Rightarrow320-10Q+25Q=545 \\ \Rightarrow25Q-10Q=545-320 \\ \Rightarrow15Q=225 \\ \Rightarrow Q=\frac{225}{15} \\  \\ \therefore Q=15 \end{gathered}

Replace back Q=15 into the expression for D to find the amount of dimes:

\begin{gathered} D=32-Q \\ =32-15 \\ =17 \end{gathered}

Therefore, the amount of dimes that the man has is 17.
