Answer:
23
Step-by-step explanation:
If you have something that says it is the f(x) or just f(something) then that is just telling you what the x equals. In this case, x=4 so you plug that into the equation.
This gives you f(4)=4(4)+7. From here, you will use the order of operations to solve.
f(4)=4*4+7
f(4)=16+7
f(4)=23
To answer (a), we will need to find the Z value for 710 hours and 990 hours.


B) 68% of data lies between one standard deviation of the mean.
850 +70 = 920
850 - 70 = 780
Answer:
The imaginary part is the multiple of i. It is common practice to use the letter z to stand for a complex number and write z = a + bi where a is the real part and b is the imaginary part. where a is the real part and b is the imaginary part.
Step-by-step explanation:
You can easily check that a complex number z = x + yi times its conjugate x – yi is the square of its absolute value |z|2. Therefore, 1/z is the conjugate of z divided by the square of its absolute value |z|2.
Complex numbers A complex number z is defined as an ordered pair z = (x, y), where x and y are a pair of real numbers.

Answer:
Step-by-step explanation:
4. 2 2/3 = 2 4/6
1/2 = 3/6
3/6 + 2 4/6 = 3 1/6
95÷3 1/6=30
