Mashutka [201]3 years ago
7 0

Answer:

This equation y=3x2+12x−2 is in standard form, or ax2+bx+c . To find the axis of symmetry, we do x=−b2a . We know that a=3 and b=12 , so we plug them into the equation. So the axis of symmetry is x=−2 .

Step-by-step explanation:

The t distribution approaches the _______________ distribution as the sample size ___________.
vredina [299]

Answer:

Normal; increases.

Step-by-step explanation:

In Statistics and probability, a student t-distribution also known as the t-distribution refers to the continuous probability distribution which can be used to estimate population parameters when the population variance or standard deviation is not known (unknown) and the sample population is relatively small. The student t-distribution is a statistical distribution which was published in 1908 by William Sealy Gosset.

The t-distribution approaches the normal distribution as the sample size increases because the parameters becomes negligibly smaller.

This ultimately implies that, when the degree of freedom of a t-distribution curve is increased in comparison with that of a normal distribution, the value of probability becomes significantly similar.

The input-output diagram represents F(x) = x+2.What is the missing output value?A. 7B. 5C. 8D. 6
asambeis [7]

Given

F(x)=x+2

To find the missing value in the diagram.

Now,

From the diagram the value of x is 5.

Then, substitute the value of x in the given equation.

That implies,

\begin{gathered} F(5)=5+2 \\ =7 \end{gathered}

Hence, the missing value is 7.
