Answer:
(2) is a right angled triangle.
Step-by-step explanation:
8²+6²=64+36=100=10²≠12²
48²+14²=2304+196=2500=50²
Answer:
(a) -3
Step-by-step explanation:
The value of f(x) approaches 3cos(π) = -3 as x approaches π from either direction. The limit is -3.

<em>Additional comment</em>
The fact that the function is defined to have a different value at x=π simply means there is a jump discontinuity there. The function is <em>not continuous</em>, because the limit and the function value differ. That doesn't detract from the fact that there is a limit, and it is -3.
Answer:
And we can find this probability with the normal standard distribution and we got:
Step-by-step explanation:
Let X the random variable that represent the variable of a population, and for this case we know the distribution for X is given by:
Where 
and 
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
Using this formula we got:
And we can find this probability with the normal standard distribution and we got:
Answer: 3.64, 10.00
Step by step:
Answer:50/50
Step-by-step explanation:
It’s a 50/50 chance because there is only two sides to a coin
