Answer:
3
Step-by-step explanation:
Here, 1:x =5:15
Solving which the value of x is 3.
The standard error of the mean is 128.125.
The formula for standard error is:
With our information, we have:
R * s = 273
r = s - 8.....s = r + 8
r(r + 8) = 273
r^2 + 8r = 273
r^2 + 8r - 273 = 0
(r - 13)(r + 21) = 0
r - 13 = 0
r = 13
r + 21 = 0
r = -21.....extraneous solution...not ur answer
r = 13
s = r + 8 = 13 + 8 = 21
so there are 13 rows.....each row containing 21 seats
200 because 5000/200 is 25 and add the profit to that to get 45. 9000/200 is 45. Sorry if that doesn't make sense :/
Answer:
-3
Step-by-step explanation:
y = 4x - 3
this equation is put in slope intercept form
y = mx + b
where m = slope and b = y intercept.
we want to find the y intercept
-3 takes the spot of b therefore the y intercept is -3
