Answer:
There is a 0.36% Chance of 1 or fewer in every 24 matches being flawed.
Step-by-step explanation:
Firstly we need to know what 1/10 of 5 is. It is 0.5.
You then need to multiply 24 by 1.5 to get 36. We then need to divide that by 100 to get a percentage and we end up with 0.36%
Here is an explanation of how to get percentages: https://www.mathsisfun.com/converting-fractions-percents.html
Answer:
Step-by-step explanation:
Each of the squares has trinomials that factor. x^2 - 14x + 49 = (x - 7)^2
When you take the square root (to get the side length) you get x - 7. So the length of each square is x - 7) = 0;..........x=7 That's the answer to a.
The answer to b is the same. The width =7
It's a square both sides have to be equal.
The length of the rectangle when the two squares are put together is 7 +7 = 14.
Answer: Question a = 7..... Question b = 7 ......... Question C = 14
Answer:
1/ (1000x^3)
Step-by-step explanation:
yes
Answer:
The constant force exerted on the ball by the wall is 119.68 N.
Step-by-step explanation:
Consider the provided information.
It is given that the mass of the ball is m = 2.2 kg
The initial velocity of the ball towards left is 7.4 m/s
So the momentum of the ball when it strikes is = 
The final velocity of the ball is -6.2 m/s
So the momentum of the ball when it strikes back is = 
Thus change in moment is: 
The duration of force exerted on the ball t = 0.25 s
Therefore, the constant force exerted on the ball by the wall is:
Hence, the constant force exerted on the ball by the wall is 119.68 N.
