If the numerator is decreased by 30% and its denominator is decreased by 50% the new fraction becomes (0.7x/0.5y)=1.4(x/y)

The increase=(1.4-1)*100=0.4*100=40%

NO TROLL COMMENTS OR IF U DONT KNOW THE ANSWER, DONT ANSWER

Answers

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

Answer:

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)
