Match each output to its input for the function. Let f(x) = −2x + 3 f(0) f(−32) f(10) f(−17) and the choices are 3,-17,37,6
Andru [333]

Answer:

Below

Step-by-step explanation:

● f(x) = -2x + 3

● f (0) = -2 (0) +3 = 3

● f(-32) = -2(-32)+3 = 64 + 3 = 67

● f(10) = -2(10) +3 = -20 + 3 = -17

● f(-17) = -2(-17) + 3 = 34 + 3 = 37

● f(10) => -17

● f(-17) => 37

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
