<u>Step-by-step explanation:</u>
Properties can help you divide because if you didn't follow them we would have incorrect answers and would be very held back in science and mathematics
If you have a calculator with statistical functions, that's the way to go.
On my TI-83, I typed in invNorm(0.88) and got the result z = 1.17.
88% of the area under the normal curve is to the left of z = 1.17.
Answer:
15.5
Step-by-step explanation:
for every hour we can say that the wage is x
hence we can create an equation:
40x + 160%*x = 644.80
now solve for x
40x + 1.6x = 644.8
41.6x = 644.8
x = 15.5
hourly wage is 15.5
