Answer:
1. (-2,-7)
2. (3,-9)
3. (7,-2)
4.(-3,9)
Step-by-step explanation:
Since the reflection is across the x-axis, the y-coordinate will be flipped.
Example: (-7,4) would become (-7,-4)
HOWEVER, if the reflection is across the y-axis, the x coordinate will be flipped.
Example: (-7,4) would become (7,4)
Answer:
It is failed to reject the null hypotehesis. There is no enough evidence that the proportion of investors who are risk-averse is not 0.6.
Step-by-step explanation:
We have to perform an hypothesis test of a proportion.
The null and alternative hypothesis are:
We state a significance level of 0.1.
The sample proportion is
The standard deviation is
The test statistic z is calculated as
The P-value of z=0.247 is P=0.8. This value is bigger than the significance level, so the efect is not significant.
It is failed to reject the null hypotehesis. There is no enough evidence that the proportion of investors who are risk-averse is not 0.6.
Answer:
Negative
Step-by-step explanation:
FGHI
Step-by-step explanation:
The square FGHI needs to be created into a reflection for true congruence of the figure thus transformed across the axis.
FGHI's co-ordinates' signs are to be reversed for reflection thus coordinates:
2,-5
4,-5
2,-7
4,-7
are made into
-2,5
-4,5
-2,7
-4,7
