Answer:
b
Step-by-step explanation:
Choice b is the only one that has the first equation properly graphed. The boundary line for that equation will have intercepts that can be found by setting the opposite variable to zero.
x-intercept = 25/2 = 12.5 (on the positive x-axis)
y-intercept = 25/5 = 5 (on the positive y-axis)
That is, the boundary line has a shallow negative slope, and is shaded below. Only graph 'b' has such a line.
Answer:
D
Step-by-step explanation:
the the 5 minus the 12 and the 0 minus the negative one all finds it way. back to the equation d
Answer:
D. n1 and n2 can be of different sizes
Step-by-step explanation:
When we are trying to develop interval estimate for difference between two populations, we first select two samples from these populations. We get the interval using the required statistic.
These are:
- Sample size of both populations. Which are n1 and n2 respectively.
- then the Sample mean of two populations
- sample standard deviation.
The samples of different sample sizes can be used and we are not obligated to make use of the same sample size.
B because it’s rounded and it’s clocks wide and just look closely you’ll get it
