Answer:
- function decreases
- (0, 2)
- y = 2
- (0, 4)
Step-by-step explanation:
-f(x) reflects the graph over the x-axis. Instead of increasing everywhere, it decreases everywhere.
__
2f(x) stretches the graph vertically by a factor of 2. The y-intercept of (0, 1) gets moved to (0, 2)
__
f(x) +2 shifts the graph up 2 units. The horizontal asymptote moves from y=0 to y=2.
__
f(x+2) shifts the graph left 2 units. The point (2, 4) on the original graph gets translated to the y-axis to become the new y-intercept (0, 4).
True , the null hypothesis of zero difference between the two population means cannot be rejected at a 0.10 level of significance.
Given :
f a 90% confidence interval for the difference in the two population means contains zero, then the null hypothesis of zero difference between the two population means cannot be rejected at a 0.10 level of significance.
at 10 % significance:
z score = 1.282
at 90 % confidence interval :
z score = 1.645
differences between population mean = 1.282
so true the null hypothesis of zero difference between the two population means cannot be rejected at a 0.10 level of significance.

Answer:
-24 - 6
Step-by-step explanation:
Let the numbers be x and y
It implies that,
So, it also says that
The difference is
So, last ratio is
