Answer:

C

Step-by-step explanation:

1) you can tell that one of the pre-images sides is 2 units and the corresponding image's is 1 so you can assume the scale factor is 2, also the preimage is on one side of the x axis and the image is on the other.

Answer:  C. a reflection across the x-axis, and then a dilation by a scale factor of 2

Step-by-step explanation:

We see that the shapes are on the opposite sides of the x-axis, and vertical lines are still vertical.  A 90° rotation would have made the vertical lines horizontal.

We see that the line that was 1 unit long is now 2 units. The line that went from 4 to 6 goes from 8 to 12. This is evidence of a dilation bt a factor of 2.

Suppose that you are examining the difference in ages between brides and grooms. You are interested in conducting a significance
lesya [120]

Answer:

Parameter = 0.5

Null hypothesis : H0 : P0 = 0.5

Alternative hypothesis ; H0 : P0 > 0.5

Pvalue = 0.99966

Step-by-step explanation:

The parameter defines a statistical value or calculation which is derived from the population.

The parameter in this scenario is the population proportion, P0 which is 0.5

The scenario above describes a scenario to test the difference in population.

The null hypothesis, that bride and groom are of the same age ;

H0 : P0 = 0.5

The alternative hypothesis ; the bride is younger Than the groom in more than half of the population.

H1 : p0 > 0.5

To obtain the Pvalue :

Test statistic : (phat - P0) ÷ √(p0(1 -p0) / n)

Phat = x/n

x = 67 ; sample size, n = 100

Phat = x / n = 67/100 = 0.67

P0 = 1 - 0.5 = 0.5

Tstatistic = (0.67-0.50) ÷ √(0.5(0.5) / 100)

Tstatiatic = 0.17 ÷ 0.05

Tstatistic = 3.4

P-value : p(Z < 3.4) = 0.99966 (Z probability calculator).

Simplify <br> 28m^2n^4 \div 8m^3n^2
Rzqust [24]
28/8 = (28÷4)/(8÷4) = 7/2;
m^2 / m^3 = (m^2÷m^2)/(m^3÷m^2) = 1/m;
n^4/n^2 = (n^4÷n^2)/(n^2÷n^2) = n^2;
Finally, we obtain 7n^2/2m ;
