How would you describe the relationship between the real zeros and x-intercepts of the function y = log (x-2)?
lakkis [162]

Answer:

When you set the function equal to zero, the solution is x = 3; therefore, the graph has an x-intercept at x = 3.

Step-by-step explanation:

The given function is y=\log (x - 2).

So, for real zeros and x-intercept, the y-coordinate must be equal to zero.

Then it becomes 0 = \log (x-2)

⇒ x - 2 = 1 {Since log 1 = 0}

⇒ x = 3

Therefore, when you set the function equal to zero, the solution is x = 3; therefore, the graph has an x-intercept at x = 3. (Answer)

The USA Today reports that the average expenditure on Valentine's Day is $100.89. Do male and female consumers differ in the amo
sergeinik [125]

Answer: $ 67.03

Step-by-step explanation:

Given : The average expenditure in a sample survey of 50 male consumers was $135.67, and the average expenditure in a sample survey of 38 female consumers was $68.64.

i.e. \overline{x}_1=\$135.67\ \ \&\ \ \overline{x}_2=\$68.64

The best point estimate of the difference between the two population means is given by :-

\overline{x}_1-\overline{x}_2\\\\=135.67-68.64=67.03

Hence, the point estimate of the difference between the population mean expenditure for males and the population mean expenditure for females : $ 67.03
