Answer:
The number itself is 508.231
Step-by-step explanation:
Any multiplying each of the numbers, we will have the specific places
Hundreds
5 * 100 = 500
Tenths
0 * 10 = 0
ones
8 * 1 = 8
Tenths = 2 * 1/10 = 2/10 = 1/5 = 0.2
Hundredths = 3/100 = 0.03
Thousandths = 1/1000 = 0.001
So we simply sum all these to get the number itself as follows
500 + 8 + 0.2 + 0.03 + 0.001 = 508.231
5>x because you can subtract 5 from both sides and 3x from both sides
0.088
Step-by-step explanation:
The total number of balls in the urn is;
8 + 5 = 12
Because the pink balls are 8, then the probability of picking a pink ball from the urn is;
8/12
To get the probability that all 6 balls drawn from the urn are pink, we will use the AND probability rule of the mutually exclusive events which means we’ll multiply the probabilities of each of the six pink balls;
8/12 * 8/12 * 8/12 * 8/12 * 8/12 * 8/12
= 0.088

Answer:
5.78% probability that exactly 2 of them use their smartphones in meetings or classes.
Step-by-step explanation:
For each adult, there are only two possible outcomes. Either they use their smarthphone in meetings or classes, or they do not. The probability of an adult using their smartphone on meetings or classes is independent of other adults. So we use the binomial probability distribution to solve this question.
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 combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
63% use them in meetings or classes.
This means that 
7 adult smartphone users are randomly selected
This means that 
Find the probability that exactly 2 of them use their smartphones in meetings or classes.
This is P(X = 2).


5.78% probability that exactly 2 of them use their smartphones in meetings or classes.
