106 students are in chorus.
About 110/200 students are in chorus.
Let x by the number of cooler
since each cooler has 25 bottles
then in total we have 25x
there are 10 friend in total to divide the bottles equally
we have 25x/10 this expresses the number of bottles each friend will get
that answers part a) of the question
now for part b)
we are told the friend brought 2 cooler
then we should have 25(2)=50 number of bottles in total
then it goes that each one of the friend will get 5 bottles (50/10)
Done !
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!
Answer:
0.9 or 90%
Step-by-step explanation:
The probability of shot is 47%
The probability of no shot is 100 -47 = 53%
The dot plot is made from the 10 repeated shots which recorded 25 scores.
The number of dots on the fifth tick is 9 of 10 shots
therefore; 9/10 = 0.9, which 90 in percentage.
