You can use both the t statistic and the z statistic to test hypotheses about the mean of population. The test that uses the t statistic is typically referred to as a t test, while the test that uses z statistic is commonly called a z test. Which of the following statements are true of the t statistic? Check all that apply. The t statistic uses the same formula as the z statistic except that the t statistic uses the estimated standard error in the denominator. The t statistic provides an excellent estimate of z, particularly with small sample sizes. The formula for the t statistic is t = (M – μ) / σM. The t statistic does not require any knowledge of the population standard deviation.

Final answer:

It is more convenient to use addition to solve the system of equations as it eliminates one of the variables when the equations are added. The solution to the system of equations is x = -6 and y = 1/2.

Explanation:

To solve the given system of equations, it is generally more convenient to use addition rather than subtraction. This is because addition eliminates one of the variables when the equations are added together, making it easier to solve for the remaining variable. Let's see how:

Using addition:

Adding the two equations together eliminates the 'x' variable:

-x + 6y + x + 6y = 9 + (-3)

12y = 6

Now, we can solve for 'y' by dividing both sides by 12:

y = 6/12 = 1/2

Substituting the value of 'y' back into either of the original equations, we can solve for 'x':

-x + 6(1/2) = 9

-x + 3 = 9

-x = 6

x = -6

Therefore, the solution to the system of equations is x = -6 and y = 1/2.

2. "three times the sum of a number and 7”.

Answers

The required equation is 3*(n + 7).

It is required to find the equation.

What is equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign. Equation, statement of equality between two expressions consisting of variables and/or numbers.

Given:

Let the number be n.

The sum of a number and 7 is n + 7

Three times the sum of a number and 7 is

3*(n + 7).

Therefore, the required equation is 3*(n + 7).
