Answer:
You have 43 nickles and 23 pennies
Step-by-step explanation:
43 x 5 = 2.15
you have 2.38 total in 66 coins
so 2.38 - 2.15 = 0.23
that will leave you with 23 pennies
23 pennies plus 43 nickles = 2.38
0.23 + 2.15 = 2.38
-1 + x + 3 -> x+2
ANSWER : x + 2
Answer:
Most everyday situations involving chance and likelihood are examples of simple probability.
Explanation:
The probability is the chance or likelihood of any event happening. In our everyday life, we unintentionally use the probability. For example, we say there is 70% chance that tomorrow will be rain, there is 50% chance that Brazil will win the world cup, there is less likelihood of he arriving today and soon. In all these concepts we are dealing with uncertainty and there is chance factor involved in all these examples. So in most everyday situations which involve chance and likelihood are actually examples of simple probability.
Answer:
The interval of increase of g(x) is 
.
Step-by-step explanation:
The interval of increase occurs when first derivative of given function brings positive values. Let be 
, the first derivative of the function is:
The following condition must be met to define the interval of increase:
The first term is always position due to the quadratic form, the second one is a first order polynomial and it is known that positive value is a product of two positive or negative values. Then, the second form must satisfy this:
The solution to this inequation is:
Now, the solution to this expression in interval notation is:
