The only zero I see here is in the 10$.

Here, it's a place holder, to show the real value of 1: if there was no "0", you would say that she has only 1 in her pocket.

but by filling the one's place with a digit, we "move" the 1 to the ten's place: which means that she will have 1 time 10, so 10 dollars (ten)

Explain how to perform a​ two-sample z-test for the difference between two population means using independent samples with sigma
Rom4ik [11]

Answer:

Step-by-step explanation:

In the two independent samples application, it involves the test of hypothesis that is the difference in population means, μ1 - μ2. The null hypothesis is always that there is no difference between groups with respect to means.

Null hypothesis: ∪₁ = ∪₂. where ∪₁ represent the mean of sample 1 and ∪₂ represent the mean of sample 2.

A researcher can hypothesize that the first mean is larger than the second (H1: μ1 > μ2 ), that the first mean is smaller than the second (H1: μ1 < μ2 ), or that the means are different (H1: μ1 ≠ μ2 ). These ae the alternative hypothesis.

Thus for the z test:

    if n₁ > 30 and n₂ > 30

     z = X₁ - X₂ / {Sp[√(1/n₁ + 1/n₂)]}

where Sp is √{ [(n₁-1)s₁² + (n₂-1)s₂²] / (n₁+n₂-2)}

How many solutions does the system below have?<br> y=1/2x+1<br> 2y - x = 2
kvasek [131]

Answer:

infinitely many

Step-by-step explanation:

Rewrite these equations as

y = (1/2)x + 1

2y = x + 2

and then solve the second for y:  y = (1/2)x + 1.  Note that these end results are identical.  The two lines coincide; that is, one lies right on top of the other.  Thus, there  are infinitely many solutions.
