Answer:
120
Step-by-step explanation: 90+30
Answer:
72%.
Step-by-step explanation:
We multiply the fraction by 100:
= 100 * 18/25
25 divides into 100 giving 4 so we have:
4 * 18
= 72%.
Answer:
There is a 25.92% probability that exactly 4 of the selected adults believe in reincarnation.
Step-by-step explanation:
For each adult, there are only two possible outcomes. Either they believe in reincarnation, or they do not believe. This means that we can solve this problem using the binomial probability distribution.
Binomial probability distribution:
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinatios of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
In this problem
There are 5 adults, so 
60% believe in reincarnation, so 
What is the probability that exactly 4 of the selected adults believe in reincarnation?
This is P(X = 4).


There is a 25.92% probability that exactly 4 of the selected adults believe in reincarnation.

<u><em>Answer:</em></u>x = −4 and x = 1
<span>
<u><em>Explanation:</em></u><u>The two formula's given are:</u>
f (x) = -x+0.5 and g (x) = x²+3x-4
By graphing the two in a graphing tool or graph paper we can find the solutions by looking at <u>the points of intersection</u> and taking the x values of those two points of intersection.
<u>Looking at the graph below:</u>
x=-4 and x=1 are the solutions to the problem.</span></span>
