Answer:
sss
Step-by-step explanation:
Answer:
mean = 2.55
Standard deviation = 1.118
Step-by-step explanation:
Probability of babies who are boys
P = 0.51
Then we have q = 1-p
= 1-0.51
= 0.49
We have n = 5
We calculate the mean as:
np
= 0.51x5
= 2.55
Therefore mean = 2.55
The standard deviation
= √variance
= √npq
= √0.51x5x0.49
=√1.2495
= 1.118
Answer:
$27,598
Step-by-step explanation:
Add 7825+2860=$10,685
Now just subtract it with $38,283
Equation if your wondering....
38283-10685=Giving you $27,598
40 hours/week * 52 weeks = 2,080 hours a year.
$30,000/year
$15.00/hour * 2,080 hours = 31,200/year
$30,000/year w/ a 10% bonus = 30,000 * 1.10 = 33,000/year
$15.00/hour and a $2,000 bonus at the end of the year = (15 * 2,080) + 2,000 = 31,200 + 2,000 = 33,200/year
I will earn the most in $15.00/hour and a $2,000 bonus at the end of the year. I will earn $33,200 per year.
This sine function has the form y = f(x) = a sin (bx + c), where |a| is the amplitude, b is the frequency, and c determines the phase shift.
The period of this sine curve is 2 pi/b, or (in this problem) 2 pi/(1/2).
The phase shift of this curve is -c/b, or -(pi/4)/(1/2). Simplify this.
The amplitude is |-3|, or just 3.
Draw a set of coordinate axes. Draw light horizontal lines through y=3 and y=-3. These are the max and min. values of this sine function.
Plot the phase shift on your x-axis.
Your sine function will begin at (phase shift value, 0) and continue for one period. Add the period to the phase shift value. Draw a sine curve beginning and ending at these two x-values.
I encourage you to share your calculations and to sketch the graph described here. Then I could give you more specific feedback on your work. Good luck!
