,q=0.8, n=400
(a,b)= *=.2+-(2.576*.02)=(.1485, .2515)
We can say with 99% confidence that the proportion of cars costing over $700,000 is in the interval (.1485, .2515).
Hope this helps!
To solve this problem, you need to recognize that the ratios of the coefficients must be equal. So the ratio for this system would be k/4 = -3/-5. Solving for k we get k = (3)*(4)/5 = 12/5, hence the answer is A. Hope that helps!
The additional measurements which must be made to determine the momentum of block 2 after the collision is both the mass and the post-collision speed of block 1
<h3>What is momentum?</h3>
Momentum can be defined as a scalar quantity that involves the multiplication of the mass of an object by its velocity.
In Physics, the momentum of an object such as a block, is calculated by using this formula;
Momentum = mass × velocity
In conclusion, we can deduce that the additional measurements which must be made to determine the momentum of block 2 after the collision is both the mass and the post-collision speed of block 1.
