Answer:
$328.13
Step-by-step explanation:
First, find the amount of time she works every day.
Between 8:45 and 5:15, there are 8.5 hours.
Subtract 1 for her lunch break, so there are 7.5 hours worked every day
Then, calculate how much she gets every day:
7.5(8.75)
= $65.625
Multiply this by 5 to find her pay for the week:
65.625(5)
= $328.13 is her total pay for the week

B.

<h2>
Option C is the correct answer.</h2>
Step-by-step explanation:
Diameter, D = 42 feet
Circumference = πD = π x 42 = 131.95 feet
Number of rotations per minute = 3
Total time = 5 minutes
Total rotations = 5 x 3 = 15
Distance traveled per rotation = 131.95 feet
Distance traveled in 15 rotations = 15 x 131.95 = 1978 feet
Option C is the correct answer.
Answer:
a) P(x=3)=0.089
b) P(x≥3)=0.938
c) 1.5 arrivals
Step-by-step explanation:
Let t be the time (in hours), then random variable X is the number of people arriving for treatment at an emergency room.
The variable X is modeled by a Poisson process with a rate parameter of λ=6.
The probability of exactly k arrivals in a particular hour can be written as:
a) The probability that exactly 3 arrivals occur during a particular hour is:
b) The probability that <em>at least</em> 3 people arrive during a particular hour is:
c) In this case, t=0.25, so we recalculate the parameter as:
The expected value for a Poisson distribution is equal to its parameter λ, so in this case we expect 1.5 arrivals in a period of 15 minutes.
Answer: y= -3/4x + 1
Step-by-step explanation:
use the point to set up slope intercept to find you y-intercept (b)
(8,-5)
y=mx+b
-5=-3/4(8)+b
-5=-6+b
b=1
