Which rule deacribes the
Marysya12 [62]

Answer:

A. {T_{-6,-2}}\circ {r_{x-axis}}(x,y)

Step-by-step explanation:

We have that, ΔABC is transformed to get ΔA''B''C''.

We see that the following transformations are applied:

1. Reflection across x-axis i.e. flipped across x-axis.

Now, ΔABC is reflected across x-axis along the line AC to get ΔA'B'C'.

2. Translated 2 units down i.e. shifted 2 units down and and then translated 6 units to the left i.e. shifted 6 units to the left.

So, ΔA'B'C' is translated 2 units downwards and 6 units to the left to get ΔA''B''C''.

Hence, the sequence of transformations is Reflection across x-axis and then Translation of 2 units down and 6 units left.

Suppose a mutual fund qualifies as having moderate risk if the standard deviation of its monthly rate of return is less than 66​
Katen [24]

Answer:

There is not sufficient evidence to conclude that the fund has moderate risk at the a = 0.01 level of significance

Step-by-step explanation:

H0: sigma= 66%

Ha:sigma < 66%

Chi square =(28-1)*2.82^2/66^2=0.049

p value =0.286

as p value>0.01 we do not can reject H0

So there is not sufficient evidence to conclude that the fund has moderate risk at the a = 0.01 level of significance
