Dmitry_Shevchenko [17]

Answer:

The critical value for the 95% confidence interval is z = 1.96.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.95}{2} = 0.025

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha

So it is z with a pvalue of 1-0.025 = 0.975, so z = 1.96.

The critical value for the 95% confidence interval is z = 1.96.

Which of the following is a solution to the differential equation xy′−3y=6 ?
ololo11 [35]

Answer:

y = 5 {x}^{3}  - 2

Step-by-step explanation:

The given differential equation is :

xy′−3y=6

We want to determine which of the following options is a solution to the differential equations.

The function that satisfies the differential equation is a solution.

We can verify that

y = 5 {x}^{3}  - 2

satisfy this differential equation.

We differentiate to get:

y' = 15 {x}^{2}

We substitute the function and its derivative into the differential equation to get:

x(15 {x}^{2}) - 3(5 {x}^{3}   - 2) = 6

We expand and simplify on the left:

15 {x}^{3}- 15 {x}^{3}   + 6= 6

This simplifies to:

6 = 6

Verified.

We can show that all the other functions do not satisfy this differential equation
