On a Sunday , a football team give away souvenir footballs to each person entering the football stadium. one group received 42 f

ootballs. A second group received 54 souvenir footballs . If each person entering the stadium received the same number of footballs , what was the greatest possible number of footballs that each ñ person could have received

Using the greatest common factor, it is found that the greatest possible number of footballs that each could have received is of 6.

<h3>Greatest common factor:</h3>
  • To find the greatest possible value divided equally between two amounts, we have to find the greatest common factor of the two amounts.

In this problem, the amounts of footballs are of 42 and 54, hence:

42 - 54|2

21 - 27|3

7 - 9

Then, gcf(42, 54) = 2 x 3 = 6, which means that the greatest possible number of footballs that each could have received is of 6.

What is the least common multiple (lcm)of 2,3, and 6
laiz [17]
<h3>Answer:  6</h3>

Explanation:

List list the multiples of each value

  • multiples of 2 = {2, 4, 6, 8, 10, ...}
  • multiples of 3 = {3, 6, 9, 12, 15, ...}
  • multiples of 6 = {6, 12, 18, 24, ...}

In each list, we see 6 show up. This is the smallest multiple that is in common; therefore, the LCM is 6

Side note: The LCM is useful to help add and subtract fractions.

A k out of n system is one in which there is a group of n components, and the system will function if at least k of the componen
Solnce55 [7]

Answer:

0.9606 = 96.06% probability that the system will function tomorrow

Step-by-step explanation:

For each component, there are only two possible outcomes. Either it works, or it does not. Components are independent. This means that 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.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

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

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

Probability of a component working:

0.7 of 0.2(rain)

0.9 of 1 - 0.2 = 0.8(no rain). So

p = 0.7*0.2 + 0.9*0.8 = 0.86

0.86 - 86% probability that the system will function tomorrow

6 components:

This means that n = 6

What is the probability that the system will function tomorrow

This is

P(X \geq 4) = P(X = 4) + P(X = 5) + P(X = 6)

In which

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 4) = C_{6,4}.(0.86)^{4}.(0.14)^{2} = 0.1608

P(X = 5) = C_{6,5}.(0.86)^{5}.(0.14)^{1} = 0.3952

P(X = 6) = C_{6,6}.(0.86)^{6}.(0.14)^{0} = 0.4046

P(X \geq 4) = P(X = 4) + P(X = 5) + P(X = 6) = 0.1608 + 0.3952 + 0.4046 = 0.9606

0.9606 = 96.06% probability that the system will function tomorrow

Use the function f(x) = 2x2 − 3x − 5 to answer the questions.
Dovator [93]

Answer:

see below

Step-by-step explanation:

A:  2x² - 3x - 5

    (2x - 5)(x + 1)

B:  Set the factored equation equal to zero and solve for x.

(2x - 5)(x + 1) = 0

2x - 5 = 0

2x = 5

x = 5/2

x + 1 = 0

x = -1

The x-intercepts are 5/2 and -1

C)  To find the end behavior, you need to look at the term in the unfactored equation with the highest exponential number.  For this equation, that is 2x².  Since the exponent is positive,  both ends of the graph will point in the same direction.  Because the leading coefficent is positive, the graph will point upwards.  The end behavior of the graph is that as the x-values approach both ∞ and -∞, the function approaches ∞.

D)  Since we know that the x-intercepts are 5/2 and -1, you can plot these points.  You also know that the graph will be in an upward U shape.  Plug in  a couple x-values and plot them to make the graphing of the equation more accurate.
