If you were to choose a female from the group, what is the probability that she is satisfied with the company's customer service? Answer choices are rounded to the hundredths place.
0.13
0.24
0.62
0.38
If a female is chosen, then the probability that she is satisfied with the company's customer service is 0.24.
What is probability?
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.
Given that, A credit card company surveys 125 of its customers to ask about satisfaction with customer service. The results of the survey, divided by gender, are shown below.
Males Females
Extremely Satisfied 25 7
Satisfied 21 13
Neutral 13 16
Dissatisfied 9 14
Extremely Dissatisfied 2 5
Here, the total number of customers is 125. (N=125).
If a female is chosen, find the probability that she is satisfied with the company's customer service. Here, conditional probability is used.
[tex]P(satisfied|female) = \frac{P(satisfied and female)}{P(females)} \\Here\\P(satisfied|female) = \frac{n(satisfied and female)}{N} \\= \frac{13}{125} \\= 0.104\\P(female) = \frac{n(female)}{N} \\= \frac{55}{125} \\= 0.44\\Now, \\P(satisfied|female) = \frac{n(satisfied and female)}{P(female)} \\= \frac{0.104}{0.44}\\= 0.24[/tex]
Hence, if a female is chosen, then the probability that she is satisfied with the company's customer service is 0.24.

What is Simplification?Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.
Given a number 9 1/100
in decimal, we can also write it as
9 1/100 = 9 +1/100
=> 9 1/100 = 9.01
therefore, in decimal the value of 9 1/100 is 9.01.

The lengths of the sides of a triangle are consecutive even integers. The perimeter is 174 feet.
Answer:
56,58,60
Step-by-step explanation:
x = 1st side of triangle
x+2 = 2nd side
x+4 = 3rd side
P = side1 + side 2 + side 3
174 = x+ x+2 + x+4
Combine like terms
174 = 3x+6
Subtract 6 from each side
174 -6 = 3x+6-6
168 = 3x
Divide by 3
168/3 = 3x/3
56 =x
1st side = 56
2nd side = 58

Answer:
9(x +y)
Step-by-step explanation:
You observe that both terms have a coefficient of 9. The distributive property lets you factor that out, so you can rewrite the expression as ...
9x +9y = 9(x +y)
_____
It might help to think of parentheses as a "bag." The expression 9(x+y) tells you the contents of one bag is (x+y) and you have 9 of them. You could think of x, and y as representing two different physical objects, for example, perhaps a ball and a cube.
The first expression, 9x +9y, tells you that you have 9 of each of these objects. The distributive property says this could be the result of dumping the contents of 9 bags, each containing one each of the objects. The expression 9(x+y) is the version of the expression that shows these objects as being grouped into 9 bags.

A town planner is building a fountain in the middle of a triangular shaped park and will place the fountain at the centroid of the triangle.
A diagram of the triangular park shown by △ABD was used to determine the location of the fountain, which will be at point G. The longest median of the triangular park, AC¯¯¯¯¯, is 150 feet.
What is the distance from the corner of the park, at point A, to the fountain?
Enter your answer in the box.
9514 1404 393
Answer:
100 ft
Step-by-step explanation:
The centroid divides each median into parts in the ratio 2 : 1. The longest part is 2/(2+1) = 2/3 of the whole length of the median.
That is, AG = 2/3AC = (2/3)(150 ft) = 100 ft.

A diagnostic test for drug use among Olympic athletes based on a blood sample was thought to be excellent. Among drug users, 98% had a positive test. Among nondrug users, 95% had a negative test. Suppose that 1% of the athletes are, indeed, drug users. What proportion of the athletes tested would have a positive test? Of those athletes whose test is positive, what proportion are really drug users?
Using conditional probability, it is found that:
5.93% of the athletes tested would have a positive test.16.53% of the athletes that test positive are drug users.What is Conditional Probability?Conditional probability is the probability of one event happening, considering a previous event. The formula is:
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which:
P(B|A) is the probability of event B happening, given that A happened.[tex]P(A \cap B)[/tex] is the probability of both A and B happening.P(A) is the probability of A happening.For this problem, the events are given as follows:
Event A: Positive test.Event B: Drug users.For this problem, the percentages associated with a positive test are:
98% of 1%(drug users).5% of 99%(non-drug users).Hence the proportion of positive tests is given by:
P(A) = 0.98(0.01) + 0.05(0.99) = 0.0593.
5.93% of the athletes tested would have a positive test.
The proportion that both tests positive and are drug users is:
[tex]P(A \cap B) = 0.98(0.01) = 0.0098[/tex]
Hence the conditional proportion is:
P(B|A) = 0.0098/0.0593 = 0.1653.
16.53% of the athletes that test positive are drug users.

Find the 2nd term in the expansion of (a + b)^7 in simplest form
Answer:
7a^6b
Step-by-step explanation:
Using the pascal triangle to do this binomial expansion, we find out that the coefficient is 7. The a variables start at the power to which you are expanding and reduce by 1 for every consecutive term. The b variables start at the power of 0 and increase by 1 for every consecutive term. Using this information, we find out that the second term in the binomial expansion (a+b)^7 is 7a^6b
Note that the power of b in the second term is b^1 which is the same as b
