HELP!!
Liono4ka [1.6K]

Answer:

Part 1: The polygon ABCDE reflected across y-axis to get the polygon MNOPQ. So, the polygon ABCDE congruent to polygon MNOPQ.

Part 2: The vertices of polygon VWXYZ are V(1, 3), W(-1, 7), X(-7, 7), Y(-5, 3), and Z(-3, 1).

Step-by-step explanation:

Part 1:

The vertices of the polygon ABCDE are A(2, 8), B(4, 12), C(10, 12), D(8, 8), and E(6, 6).

The vertices of the polygon MNOPQ are M(-2, 8), N(-4, 12), O(-10, 12), P(-8, 8), and Q(-6, 6).

We need to find the transformation or sequence of transformations that can be performed on polygon ABCDE to show that it is congruent to polygon MNOPQ.

The relation between the vertices of ABCDE and MNOPQ are defined as

(x,y)\rightarrow (-x,y)

It means the polygon ABCDE reflected across y-axis to get the polygon MNOPQ. So, the polygon ABCDE congruent to polygon MNOPQ.

Part 2:

If polygon MNOPQ is translated 3 units right and 5 units down, then

(x,y)\rightarrow (x+3,y-5)

M(-2,8)\rightarrow V(-2+3,8-5)=V(1,3)

N(-4,12)\rightarrow W(-4+3,12-5)=W(-1,7)

O(-10,12)\rightarrow X(-10+3,12-5)=X(-7,7)

P(-8,8)\rightarrow Y(-8+3,8-5)=Y(-5,3)

Q(-6,6)\rightarrow Z(-6+3,6-5)=Z(-3,1)

Therefore the vertices of polygon VWXYZ are V(1, 3), W(-1, 7), X(-7, 7), Y(-5, 3), and Z(-3, 1).

Solve the system y = 3x + 2 and 3y = 9x + 6 by using graph paper or graphing technology. What is the solution to the system? (2
Monica [59]

Answer:

The system has infinite solutions

Step-by-step explanation:

Notice that the 2nd eq can be written as y=3x+2, exactly the same first equation, so it doesnt give anything to solve it

You can see the attached picture represents the eq. 1

The second eq. is also represented in that picture, just it doenst seems, because it is hide under the first

Test the following claim. Identify the null​ hypothesis, alternative​ hypothesis, test​ statistic, critical​ value(s), conclusio
Vladimir79 [104]

Answer:

A Null hypothesis (H0): mu equals 200 sec

Alternate hypothesis (H1): mu greater than 200 sec

Test statistic (z) is 5.31

Critical value is 1.645

Conclusion: reject the null hypothesis

Final conclusion that addresses the original claim: the result obtained suggest that the advice given in the manual is not valid

Step-by-step explanation:

Null hypothesis is a statement from the population parameter subject to testing

Alternate hypothesis is also a statement from the population parameter that negates the null hypothesis

Test statistic (z) = (sample mean - population mean) ÷ sd/√n

sample mean = 245 sec, popi mean = 200 sec, sd = 53.5 sec, n = 40

z = (245 - 200) ÷ 53.5/√40 = 45 ÷ 8.47 = 5.31

This is a one tailed test.The critical value using a significance level of 0.05 is 1.645

Conclusion: since the test statistic (5.31) is greater than the critical value (1.645), reject the null hypothesis

Final conclusion: There is sufficient evidence to support the claim that the sample is from a population of songs with a mean greater than 200 sec

This result suggest that the advice offered in the manual is not valid
