Answer:
y= 0.05x + 50
Step-by-step explanation:
Slope intercept form: y= mx + b
The total monthly cost of the telephone plan is $50 plus a charge of $0.05 per minute.
The charge is <em>dependent</em> on the minutes used.
Whenever we see <em>per</em>, we automatically have our slope.
Slope: 0.05
And since 50 is the <em>independent</em> variable, 50 is our y-intercept.
y= 0.05x + 50
Multiply 3.4 and t then 3.4 and 8. after add 3.4 and 1.8 then I think you divide
Answer:
225pi=a*9
divide both sides by 9
25pi=a
a=pir^2
25pi=pir^2
cancel out pi
25=r^2
so the length of the radius is 5
The T statistic does not require any information about the population.
<h3>
What is T- statistic?</h3>
The T - statistic is the ratio of the predictable value of a parameter from its hypothesized value to its standard disputable values.
The T statistic uses the sample variance instead of the population variance.
Since, the T statistic depends on the hypothesized population mean. So in place of the standard deviation of population, size or mean of the population, T-statistic depends on the sample mean, the sample standard deviation and the sample size .
Thus, The T-statistic does not require any information about the population
