We assume that
.. (number in school)/(560 lunches sold) = (60 students sampled)/(40 eat lunch)
Then
.. (number in school) = 560*60/40 = 840
We have the following functions:
f (x) = x3 - 3x2 - 13x + 15
f (x) = x4 + 3x3 - 8x2 + 5x - 25
f (x) = x3 - 2x2 - x + 2
f (x) = -x3 + 13x - 12
Factoring we have:
f (x) = x3 - 3x2 - 13x + 15 -------> x + 3
f (x) = x4 + 3x3 - 8x2 + 5x - 25 -> x + 5
f (x) = x3 - 2x2 - x + 2 ------------> x - 2
f (x) = -x3 + 13x - 12 -------------> x + 4
Answer:
40.1% probability that he will miss at least one of them
Step-by-step explanation:
For each target, there are only two possible outcomes. Either he hits it, or he does not. The probability of hitting a target is independent of other targets. 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.
0.95 probaiblity of hitting a target
This means that 
10 targets
This means that 
What is the probability that he will miss at least one of them?
Either he hits all the targets, or he misses at least one of them. The sum of the probabilities of these events is decimal 1. So
We want P(X < 10). So
In which
40.1% probability that he will miss at least one of them
Answer:
The correct equitation is 60=\frac{3}{5}\times10060=
5

5
×60
Step-by-step explanation:
To determine:
A flower show has an inventory of 60 tulips and 100 roses?
Information Fetching and Solution Steps:
A flower show has an inventory of
60 tulips
100 roses
So,
60=\frac{3}{5}\times10060=
5
3
×100
or
100=\frac{5}{3}\times60100=
3
5
×60
Other options can not be true as they do not satisfy the equation. For example,
60 = 3\times 10060=3×100 can not be true as the L.H.S ≠ R.H.S
Therefore, the correct equitation is 60=\frac{3}{5}\times10060=
5

×100 OR 100=\frac{5}{3}\times60100=
