Answer:
a) 0.3125
b) 45
Step-by-step explanation:
Remark
5 students own a smart phone
11 do not.
Part A
The probability of owning a smart phone is 5/16. Where did the 16 come from.? You must use a total for the sample. You can't choose someone without a smart phone and figure out the probability of doing that if you use 11 in the denominator.
So the answer is 5/16 = 0.3125
Part B
You have to set up a proportion for this.
x / 144 = 5/16
Notice where the 144 goes. It is across from 16. Both of them represent the total number of students. Multiply both sides by 144
x * 144 / 144 = 5 * 144/16
x = 720 / 16
x = 45

y=4sin(1/4x)
Step-by-step explanation:
1. Either sin or cos graph
y=asin(b(x-c))+d or y=acos(b(x-c))+d
a = amplitude
b = period (2π/b = answer)
c = x-shift (negative)
d = y-shift (positive)
2. Graph each possibility
a = 4
b = 2π/8π = 1/4
c = 0
d = 0
y=4sin(1/4x) or y=4cos(1/4x)
