Answer:
.0942816
Step-by-step explanation:
Given
Sample size n = 150
Sample proportion 
= 
= 0.28
Confidence interval = 
= .99
1 - confidence interval = 1 - 0.99 = .01
For 99
confidence interval
( Z = 2.576 )
= .0942816
Step-by-step explanation:
Given
f(x) = 2x - 10
f^-1(x) = ?
Now
Let y = f(x)
y = 2x - 10
Interchanging the roles of x and y we get,
x = 2y - 10
x + 10 = 2y
y =(x + 10) / 2
f^-1(x) = (x + 10)/ 2
Hope it will help :)❤
Edit : the rest is zero : la console is right, but, after check : it's : 3x^2 + 13x + 4 .... and not + 5 (degree 0 term)
3x^3 - 2x^2 - 61x - 20 | x - 5 -3x^3+15x^2................3x^2 + 13x + 4 ........ 13x^2 - 61x -20 .........-13x^2 +65x ......................4x -20 .....................-4x +20 .............................0
finally :
(3x^3 - 2x^2 - 61x - 20) / (x - 5) = 3x^2 + 13x + 4
Hope this helps any sorry how its all scattered
-72 is the answer to this problem, hope it helps.
The correct answer is B.
An undefined slope is indicated by:
x= a number, which looks like a vertical line.
A line perpendicular to that is indicated by:
y = a number, which looks like a horizontal line.
Answer:
30
Step-by-step explanation:
If x be the number of hours that Michelle works, then his regular hourly and overtime wages y is given by
y = 25x for 0 ≤ x ≤ 38
and y = 30(x - 38) + 950 for x > 38
So, it is clear that when Michelle works more than 38 hours, then he gets the overtime wage and then only his hourly wage is 30 per hour.
So, option B will be correct. (Answer)
