ing statement(s) regarding study design, data collection and hypothesis test is/are correct?a. We have to make sure grocery items sampled from Piggly Wiggly are different from grocery items sampled from Publix.b. We have to make sure grocery items sampled from Piggly Wiggly are the same with grocery items sampled from Publix.c. The more data we collect, the better; because we can use 2-sample z test instead of 2-sample t test if the sample size is greater than 30.d. We should use paired t test.e. We should use 2-sample t test with unequal standard deviation.f. We should use 2-sample pooled-t test (equal standard deviation).

Please help!! also please explain I would like to understand.​

Answer:

A

Step-by-step explanation:

First, put this equation in slope intercept form.

y=mx+b

Where m is the slope and b is the y intercept.

y+1>2(x-1) \\ \\ y+1>2x-2 \\ \\ y>2x-3

Since it's greater than, the solution set is above the line, effectively eliminating graph D.

Now we should graph it.

We can see that the point (2,1) is on the graph, and only Graph A has that point. Therefore, Graph A is the correct graph.

choose the equation that shows a step in the process of completing the square on the given quadratic. y = x2 8x – 3 y = x2 8x 8
posledela
Y = x^2 + 8x - 3
y = x^2 + 8x + (8/2)^2 - 3 - (8/2)^2
y = x^2 + 8x + 16 - 3 - 16
