The range of the function given below is the set of all positive real numbers greater than 7. F(x) = 7 + 3x A. True B. False
2 answers:
Answer:
Option A. True
Step-by-step explanation:
Range of the function is defined by the values of F(x) by plugging in the values of x in the function.
In other words when we graph the function as
x 1 2 3 4
F(x) 10 16 30 88
Then the x values define the domain of the given function and values of f(x) define the range.
Therefore, range of the given function will be all positive real numbers greater than 7.
Option A. is the answer.

Answer:
diameter of #12 wire = (80.80 0.001) = 0.08080 inches
Step-by-step explanation:
i) #12 wire is 80.80 mils
ii) Therefore diameter of #12 wire = 80.80 mils.
iii) 1 mil = 0.001 inch
iv) therefore diameter of #12 wire = (80.80 0.001) = 0.08080 inches
Answer:
(351.04, 368.96)
Step-by-step explanation:
Given that population mean= 360
Std devitaion = 4
margin of error = 2.5%= 0.025
Since population std deviation is known we can use Z critical value
For two tailed critical value for 2.5% would be
2.24
Margin of error = ±Critical value*std deviation
= ±2.24(4)
= ±8.96
Confidence interval =(Mean - margin of error, mean + margin of error)
=
