To add fractions, find the LCD and then combine.
Answer:
The solution set is the set of all real numbers.
Step-by-step explanation:
Solve:
Like terms are those terms which have same variable to the same power:
Combine like terms;
Subtract 20 from both sides we get;
Simplify:
Add 3n to both sides we get;
Simplify:
for all n
Thus, the given system is dependent.
Therefore, the solution set is set of all real numbers.

b. What is the probability that between 50 and 75 (inclusive) had fished?
c. If the 180 men selected for the interview were selected by the marketing department of a sporting-goods company based on information obtained from their mailing lists, what would you conclude about the reliability of their survey results?
Answer:
(a) The probability that fewer than 50 had fished is 0.0002.
(b) The probability that between 50 and 75 (inclusive) had fished is 0.6026.
(c) The survey results are not reliable.
Step-by-step explanation:
Let X = number of men who had fished during the year.
The probability of the random variable X is, p = 0.41.
A random sample of n = 180 men are selected.
The random variable X follows a Binomial distribution with parameters n = 180 and p = 0.41.
A Normal approximation to Binomial is applied when the following conditions are met,
Check:
Thus, the distribution of x can be approximated by a Normal distribution with:
Mean =
Standard deviation =
(a)
Compute the probability that fewer than 50 had fished as follows:
Thus, the probability that fewer than 50 had fished is 0.0002.
(b)
Compute the probability that between 50 and 75 (inclusive) had fished as follows:
Thus, the probability that between 50 and 75 (inclusive) had fished is 0.6026.
(c)
If the sample of 810 men are selected from mailing list then it is highly probable that the sample is not a representative of the true population, i.e. sports men.
Because the people interested in sports are less likely to be interested in fishing.
Thus, it could be concluded that the survey results are not reliable.

A) 6 souvenir brochure
B) 10 souvenir brochure
C) 12 souvenir brochure s
D) 18 souvenir brochure
6 souvenir brochures must be purchased in order Which is the correct answer would be an option (A)
A linear equation is defined as an equation in which the highest power of the variable is always one.
The slope-intercept form is y = mx+c, where the slope is m and the y-intercept is c.
For the functions, we have that:
The set-up fee is the admission fee.
The price per souvenir brochure is the slope.
Hence the functions are given by:
R(x) = 10 + 6.25x
S(x) = 13 + 5.75x
We have been given the total cost at Concert R and Concert S to be the same.
So R(x) = S(x).
⇒ 10 + 6.25x = 13 + 5.75x
⇒ 0.5x = 3
⇒ x = 3/0.5
⇒ x = 6.
Therefore, 6 souvenir brochures must be purchased in order for the total cost at Concert R and Concert S to be the same.
