Answer:
786.6
Step-by-step explanation:
Anything to the ^0 is 1 so its 1 x 6.6 + 100 x 7.8
6.6 + 780
786.6
The price y is a function of x, the speed of the processor.
In function notation this means, y=f(x), where f(x)=<span>101x + 207.85.

For example to calculate the (approximate) price of a laptop with processor 4 gigahertz, we let x=4, and plug in f.
That is the price y for x=4 is calculated by y=f(4).
So, since y=f(x)=<span>101x + 207.85, the (expected) price of a laptop with processor speed 2.5 gigahertz is :
y=f(2.5)=101(2.5)+207.85= 460.35 ($)
Answer:
</span>C. $460
Answer:
DF = 458
Step-by-step explanation:
In statistics, T-test have an extensive application. T-tests are used in hypothesis testing or inference about the population mean when the population standard deviation is not known. Nevertheless, they are used in making inference in paired samples or dependent samples t-test as well as independent samples.
The degrees of freedom, DF, is a characteristic of the student's t distribution which is used in T-tests. In a simple T-test;
DF = n - 1
where n is the sample size
Given n is 459, DF = 459 - 1 = 458
Therefore, DF = 458
