Answer: 33 1/3%
Step-by-step explanation:
Percentage increase of the shirt will be calculated as:
= Price Increase / Old price × 100%
Price Increase = $20 - $15 = $5
Old price = $15
Percent increase = Price Increase / Old price × 100%
= 5/15 × 100
= 1/3 × 100
= 33 1/3%
Answer:
They are equal and act in opposite directions.
Step-by-step explanation:
Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.
Answer:
14
Step-by-step explanation:
From the given information:
suppose, Y is the number of times a coin is being flipped.
If the coin is flipped for the first time and we get H, then we have:
TTT = ![\dfrac{1}{2}(Y+1)](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B2%7D%28Y%2B1%29)
Afterward, if we get H, then we waste two times plus the probability of this event
.
Therefore, we have : ![\dfrac{1}{4}(Y+2)](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B4%7D%28Y%2B2%29)
Afterward, if we get H, then we waste three times plus the probability of this event
.
Therefore, we have : ![\dfrac{1}{8}(Y+3)](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B8%7D%28Y%2B3%29)
If we got T at the third time, then;
T = ![\dfrac{1}{8}(3)](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B8%7D%283%29)
Thus, average number of headsthat you’ll see until gettingTTT can be expressed as:
![= \dfrac{1}{2}(Y+1)+ \dfrac{1}{4}(Y+2)+ \dfrac{1}{8}(Y+3)+ \dfrac{1}{8}(3)](https://tex.z-dn.net/?f=%3D%20%5Cdfrac%7B1%7D%7B2%7D%28Y%2B1%29%2B%20%5Cdfrac%7B1%7D%7B4%7D%28Y%2B2%29%2B%20%5Cdfrac%7B1%7D%7B8%7D%28Y%2B3%29%2B%20%5Cdfrac%7B1%7D%7B8%7D%283%29)
= 14
The correct answer is the second choice, -52
