Answer:
bc the are both the same numbers. So the answer is 12. :>
Step-by-step explanation:
3x + 4 < 40
This is my answer
For this case we must find the inverse of the following function:
We follow the steps below:
Replace f(x) with y:
We exchange the variables:
We solve for "y":
Multiply by -2 on both sides of the equation:
We raise both sides of the equation to the square to eliminate the radical:
We subtract 3 from both sides of the equation:
We change y by f ^ {- 1} (x):
Answer:
Answer:
Increase by 5% ;
Remain unchanged
Step-by-step explanation:
Given that:
Raise received by all workers = 5%
Since the raise in salary cuts across all employees, then the average or mean salary will also increase by the same amount.
y = m ± c
y = new mean ; m = initial mean ; c = increase
The standard deviation on the other hand isn't affected due to change in a constant value. That is the standard deviation of a. Constant value is Zero. Hence, the standard deviation remains unchanged.

Step-by-step explanation:
since the diagonals cut the rectangle into isosceles triangles the base angles are congruent and vertical angles are also congruent
