Angelique needs 3 8/15 hours to completely build the fence.
What is a unitary method?A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
Given, Angelique builds a fence and she can build 5/8 of the fence in 2 5/6 = 17/6 hours.
We know a number multiplied to its reciprocal is 1.
Therefore, The amount of time Angelique needs to complete the fence is,
(5/8)×(8/5) the complete fence in (17/6)×(8/5) hours.
= 136/30 hours.
= 3 16/30 hours.

Dominic works on the weekends and on vacations from school mowing lawns in his neighborhood. For every lawn he mows, he charges $12. Complete the table. Then determine ordered pairs, and create a labeled graph. 1. How many lawns will Dominic need to mow in order to make $240? _________(blank 1) 2. How much money will he make if he mows 9 lawns? _________(blank 2) Question 1 options: Blank # 1 Blank # 2
Answers
Answer:
\(20\ lawns = \$240\)
\(9 \ lawns = \$108\)
See Attachment for Graph
Step-by-step explanation:
Given
\(1\ lawn = \$12\)
Solving (a): Number of lawns in $240
\(1\ lawn = \$12\)
Multiply both sides by 20
\(20 * 1\ lawn = \$12 * 20\)
\(20\ lawns = \$240\)
Solving (b): Cost of mowing 9 lawns
\(1\ lawn = \$12\)
Multiply both sides by 9
\(9 * 1\ lawn = \$12 * 9\)
\(9 \ lawns = \$108\)
To create a graph, we need to generate a formula;
If
\(1\ lawn = \$12\)
\(2\ lawn = \$24\)
\(3\ lawns = \$36\)
\(x\ lawns = \$12x\)
So:
The graph formula is
\(y = 12x\)

What is the sample population ?
A point estimate is a single value used to estimate a population's unknown parameter. The sample proportion (denoted by p), in the context of determining the population proportion, is a widely used point estimate. The sample proportion is determined by dividing the sample's success rate by the sample size.
The sample must be representative of the population for it to be a reliable point estimate of the population proportion. To accurately reflect the proportions of various groups or categories present in the population, the sample should be chosen at random.

prove that a group cannot be the union of two proper subgroups. deduce that a ring cannot be the union of two proper subrings.
Answers
A group cannot be the union of two proper subgroups is proved.
To understand why a group cannot be the union of two proper subgroups, let us first define what a subgroup is. A subgroup of a group G is a subset H that is itself a group under the same operation as G. In other words, H must satisfy the following conditions:
The identity element of G belongs to H.
H is closed under the operation of G.
For each element g in H, the inverse element of g in G is also in H.
Now, consider the element ab. Since a is not in H, but H is a subgroup of G, it follows that the inverse element of a must be in K. Similarly, since b is not in K, but K is a subgroup of G, it follows that the inverse element of b must be in H. Therefore, we have:
ab = a(eb) = (ae)b
Since ae is in H and b is in K, we have shown that ab is in the intersection of H and K. But since H and K are proper subgroups, their intersection must be a subgroup of G that is smaller than either H or K.
Therefore, a group cannot be the union of two proper subgroups.
Now, let us apply this result to rings. A ring is a set R that is closed under two operations, usually addition and multiplication, and satisfies certain axioms.
A subring of R is a subset S that is itself a ring under the same operations as R. If R were the union of two proper subrings S and T, we could use a similar argument as for groups to show that R is not a ring.
In particular, we would take two elements a and b that are not in S and T, respectively, and consider the product ab. Since S and T are rings, they both contain the identity element of R under multiplication, which we denote as 1.
We would then show that ab is in the intersection of S and T, which is a smaller subring of R. This would contradict the assumption that R is the union of two proper subrings.
Therefore, a ring cannot be the union of two proper subrings.

At a local college, 61 of the male students are smokers and 549 are non-smokers. Of the female students, 156 are smokers and 444 are non-smokers. A male
student and a female student from the college are randomly selected for a survey. What is the probability that both are non-smokers?
Do not round your answer. (If necessary, consult a list of formulas.)
Answers
The probability of randomly selecting a male student and female student are non-smokers is 0.6771
What is probability?
Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.
Probability = (Number of possible outcomes)/(Total number of outcomes)
According to the given question:
Number of male students are smokers = 61
Number of male students are non smokers = 549
Total number of male students = 610
Number of female students are smokers = 156
Number of female students are non smokers = 444
Total number of female students = 600
Probability that both are non smokers is given by
P (non-smoker males) x P (non-smoker females)
= \(\frac{549}{610} . \frac{444}{600}\)
= 0.915 x 0.74
= 0.6771
Therefore the probability that both male and female are non-smokers is 0.6771.
