Answer:
Rectangle C
Step-by-step explanation:
Rectangle C was transformed to Rectangle E.
To see how this occurs, let's follow point F (-2, 5) through the two transformations.
(a) Reflection across the x-axis
The x-coordinate does not change, but the y-coordinate changes sign.
Thus, F ⟶ F' (-2, -5).
(b) Translating up two units
The x-coordinate does not change, but the y-coordinate increases by 2..
Thus, F' ⟶ F" (-2, -3).
You can follow the same transformations for the other three corners of rectangle C.
Rectangle C ⟶ Rectangle E
Answer:
Step-by-step explanation:
From the given information:
We can compute the null hypothesis & the alternative hypothesis as:
The degree of freedom = n - 1
The degree of freedom = 5 - 1
The degree of freedom = 4
At the level of significance of 0.05 and degree of freedom 4,
the rejection region = 9.488
However, we can compute the chi-square X² goodness of fit test as:
months frequency (p) observed O Expected E Chi-square
Dec 0.2 16 16
Jan 0.250 11 20
Feb 0.200 16 16
Mar 0.200 18 16
Apr 0.150 19 12
Total 1.000 80 80 8.3833
∴
The test statistics X² = 8.3833
Thus; we fail to reject the since test statistics X² doesn't fall in the rejection region.
Therefore; there is sufficient evidence to conclude that the distribution of snowfalls in her hometown is not similar to the claimed percentage.
