juin [17]

Answer:

d. I and III only

Step-by-step explanation:

I. The seeds should be randomly assigned to a treatment.

III. The number of successful seeds and unsuccessful seeds in each group should be at least 10.

The distribution of difference between two sample proportions :

Given :

Proportion 1 = P1 ;

Proportion 2 = P2 ;

Sample assignment for both samples 1 and 2 into the different treatment groups should be randomized, that is a simple random sampling of subjects into the treatment and control group. The sample design for difference between two sample proportions should be independent.

Finally each of the two proportions P1 and P2 should record a minimum of 10 successes and 10 non - successful Occurrences.

-3=12y-5(2y-7). Solve for y

Yuliya22 [10]

1. distribute the parentheses.
-3=12y-10y+35

2. Move the constants to the other side
-3-35=12y-10y

3. Subtract the terms
-38=2y

4. Divide by 2 to get y by itself
y=-19

Which set of parametric equations represents the following function? y=/x+3?

Darina [25.2K]

The given equation is:

$y= \sqrt{x+3}$

We need to find which set of parametric equations, result in the equation given above. The correct answer is option A.

$x=5t, y= \sqrt{5t+3}$

From first equation, we can write t =x/5. Using this value in second equation, we get:

$y= \sqrt{5( \frac{x}{5} )+3} \\ \\ 
y= \sqrt{x+3}$

Thus the set of equations in option A result in the given relation.
So, the answer to this question is option A
