Step-by-step explanation:
gradpoint
The binomials (x + 1) and ( x + 5 ) are factors of the quadratic expression of x² + 6x + 5.
What are the factors of the quadratic expression?Given the quadratic expression in the question:
x² + 6x + 5
To find the binomials that are factors of the quadratic expression x² + 6x + 5, we have to factorize the quadratic expression.
The binomials will be in the form of (x + a)(x + b).
x² + 6x + 5
Now, factorizing the expression, consider a pair of integers, "a" and "b," such that their sum is 6 and their product is 5.
The integers that satisfy these conditions are 1 and 5.
Hence, plug them in:
(x + a)(x + b)
( x + 1 )( x + 5 )
Therefore, the factors of the expression are ( x + 1 ) and ( x + 5 ).

A bag contains 4 red marbles, 3 blue marbles and 2 green marbles. If two marbles are drawn out of the bag, what is the probability, to the nearest 10th of a percent, that both marbles drawn will be red?
The probability of drawing two red marbles is approximately 16.7%.
Explanation:To find the probability of drawing two red marbles from the bag, we need to find the probability of drawing one red marble and then, given that the first marble was red, drawing another red marble. The probability of drawing a red marble on the first draw is 4/9 (since there are 4 red marbles out of a total of 9 marbles). After the first marble is drawn, there are now 8 marbles left in the bag, including 3 red marbles.
Therefore, the probability of drawing a red marble on the second draw, given that the first marble was red, is 3/8. To find the probability of both events occurring, we multiply the probabilities: (4/9) × (3/8) = 1/6, or approximately 16.7%.

The probability of drawing 2 red marbles without replacement from a bag containing 4 red, 3 blue, and 2 green marbles is 16.7%.
Explanation:The question is asking for the probability of drawing two red marbles from a bag that contains 4 red marbles, 3 blue marbles, and 2 green marbles, without replacing the first one drawn.
Firstly let's figure out the total number of ways to draw 2 marbles from a bag of 9 marbles. Using combination formula, the total number of possible ways is: 9C2 = 36.
Now, how many ways can you draw 2 red marbles from 4? That will be: 4C2 = 6 ways.
So the probability of drawing 2 red multiplies, without replacement, is therefore 6 / 36 = 0.167 or 16.7% when rounded to the nearest tenth of a percent.

The cable company is analyzing data from two satellite television providers to determine whether their users spend more time watching live television or shows that have been recorded. Satellite Company X : 89 live, 430 recorded Satellite Company Y : 65 live, 94 recorded What is the probability that a randomly selected customer from Company Y watches recorded shows more often than live television? Give your answer in percent form rounded to the nearest whole percent.
Answer:
59%
Step-by-step explanation:
The information from Satellite Company Y is:
65 people watch live and 94 people watch recorded.
The total number of people from Y is:
65 + 94 = 159
So the probability that a random person from Y watches recorded shows more often is given by the division of the number of people watching more recorded shows (94) over the total number of people (159):
Probability = 94 / 159 = 0.5912 = 59.12%
Rounding to nearest whole percent, we have 59%

There is a bag filled with 6 blue and 5 red marbles. A marble is taken at random from the bag, the colour is noted and then it is replaced. Another marble is taken at random. What is the probability of getting exactly 1 red?
The probability of getting exactly 1 red marble is 60/121.
Given data:
To find the probability of getting exactly 1 red marble, we need to consider the two possible scenarios:
Getting a red marble on the first draw and a blue marble on the second draw.
Getting a blue marble on the first draw and a red marble on the second draw.
The probability of getting a red marble on the first draw is 5/11, since there are 5 red marbles out of a total of 11 marbles in the bag.
The probability of getting a blue marble on the second draw is also 6/11, since we replace the marble after the first draw, so the number of marbles remains the same.
The probability of the first scenario occurring is (5/11) * (6/11) = 30/121.
Similarly, the probability of the second scenario occurring is (6/11) * (5/11) = 30/121.
To find the total probability of getting exactly 1 red marble, we add the probabilities of these two scenarios:
Total probability = (30/121) + (30/121)
= 60/121.
Hence, the probability of getting exactly 1 red marble is 60/121.

The probability of drawing exactly one red in two draws, considering the order, is the sum of the two scenarios: 'red then blue' and 'blue then red'. Here, the total probability is calculated as (5/11 * 6/11) + (6/11 * 5/11).
Explanation:The question presented falls under the concept of probability in Mathematics. We have a bag with 6 blue and 5 red marbles. A marble is chosen, its color is recorded, and then it is put back in the bag before another marble is chosen. Thus, the color of the first marble selected does not have any influence on the color of the second marble because of replacement.
To get the probability of drawing one red marble in two attempts, we can consider two possibilities: either the first draw is red and the second is blue, or the first draw is blue and the second is red.
Scenario 1: The first marble drawn is red and the second marble drawn is blue. The probability of drawing a red marble on the first attempt is 5/11, since there are 5 red marbles out of a total of (6+5)=11 marbles. After replacing the first marble, the probability of drawing a blue marble on the second try is 6/11. Therefore, the total probability for this possibility is the product of both individual probabilities: (5/11) * (6/11).
Scenario 2: The first marble drawn is blue and the second marble drawn is red. The probability is calculated in the same manner resulting into (6/11) * (5/11).
Finally, to get the total probability of drawing exactly one red marble in two draws, we add the probabilities for the two scenarios: (5/11 * 6/11) + (6/11 * 5/11).

A poll is given, showing 45% are in favor of a new building project.
If 3 people are chosen at random, what is the probability that exactly 1 of them favor the new building project?
The probability of exactly 1 person favoring the new building project out of 3 people chosen at random is approximately 0.4083, or 40.83%.
Use the concept of probability defined as:
Probability is the ratio of the number of favorable outcomes to the total number of outcomes for the occurrence of an event.
Given that,
A poll was conducted on a new building project.
The results of the poll represent 45% of the respondents were in favor of the new building project.
To calculate the probability that exactly 1 person favoring the new building project out of 3 people chosen at random:
Use the binomial probability formula:
[tex]P(X=k) = (^nC_k) p^k (1-p)^{(n-k)}[/tex]
Where P(X=k) is the probability of getting exactly k favorable responses, and n is the total number of people chosen.
In this case, n = 2,
k is the number of favorable responses, in this case, 1,
p is the probability of an individual favoring the new building project in this case, 0.45,
And (1-p) is the probability of an individual not favoring the new building project in this case, 0.55.
Now substitute the values into the formula:
[tex]P(X=1) = (^3C_1) (0.45^1) (0.55^{(3-1)})[/tex]
Calculating the values:
[tex]^3C_1 = 3[/tex]
(which represents the number of ways to choose 1 favorable response out of 3 people),
[tex]0.55^{(3-1)} = 0.3025.[/tex]
Substituting these values back into the formula:
P(X=1) = (3)(0.45)(0.3025)
Calculating further:
P(X=1) = 0.4083
Hence,
The probability of exactly 1 person favoring the new building project out of 3 people chosen at random is approximately 0.4083, or 40.83%.

Final answer:
The probability of exactly 1 out of 3 individuals favoring a new building project is 40.35%.
Explanation:
The probability of a person favoring a new building project is 45%.
To find the probability that exactly 1 out of 3 chosen individuals favor the project, we use the binomial probability formula:
Calculate the probability of 1 person favoring the project: 0.45 * 0.55 * 0.55 = 0.1345
Calculate the number of ways 1 person can be chosen out of 3: 3 choose 1 = 3
Multiply the two results: 3 * 0.1345 = 0.4035
Therefore, the probability that exactly 1 out of 3 individuals favor the new building project is 0.4035 or 40.35%.
