Answer:
So the answer for this case would be n=247 rounded up to the nearest integer
Step-by-step explanation:
We know that the standard deviation is :
represent the deviation
The margin of error is given by this formula:
(a)
And on this case we have that ME =25 and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
The critical value for 95% of confidence interval now can be founded using the normal distribution and the critical value would be
, replacing into formula (b) we got:
So the answer for this case would be n=247 rounded up to the nearest integer
The answer is 155 because 124/4 is 31 so the average rate of change is 31 so multiply by 5 and it gives you 155
Answer:
The standard form is: 
The function is of the 3rd degree.
The leading coefficient is 8.
The constant term is -3.
Step-by-step explanation:
Placing in standard form:
To place in standard form, we solve the operations. So




Degree:
The degree is given by the highest power of x, which, in this exercise, is 3.
Leading coefficient:
The leading coefficient is the term that multiplies the highest power of x. In this exercise, the higher power of x is
, which is multiplied by 8. So the leading coefficient is 8.
Constant term:
The constant term is the one which does not multiply a power of x. So in this exercise, it is -3.
Since 360 is a full loop around the circle, the points end up in the exact same place.
Answer:
x+3y=7
Step-by-step explanation:
y-2= -1/3(x-1)
-3y+6= x-1
x+3y= 7
