Answer:
Y= 1/2
Step-by-step explanation:Equation of a straight line:Gradient= y2-y1/x2 -x2=m
Given that:
y2=1
y1=Y
x1=-4
x2=-5
1-y/-4-(-5) =2
1 - y/-4+5 =2
cross multiply
2(1-y) = -4+5
2-2y =1
-2y =1-2
-2y = -1
divide both sides by the coefficient of y
Y = 1/2

What is referred as the unitary method?The unitary method is a process that determines the value of a specific unit from the value of multiple units, as well as the value of multiple units from of the value of a single unit.We must first divide to find the value of one thing, and then multiply to determine the value of much more or fewer things.Now, for the given question;
The cost of 3 pounds of shrimp at Earl's shrimp hut = $38.25.
3 pounds ---------> $38.25
Divide both sides by 3.
1 pound ------------>$12.75
Multiply 12 on both side;
12 pounds -------------> $153.
The cost of 4 pounds of shrimp at shrimpie's for 50.00.
4 pounds ---------> $50.00.
Divide both sides by 4.
1 pound ------------>$12.5
Multiply 12 on both side;
12 pounds -------------> $150.
Cost difference = Earl's shrimp hut - shrimpie
Cost difference = $153 - $150 = $3.
Therefore, Mr. Alfonso will save $3 from the purchase of 12 pounds of shrimp from shrimpies.

If the relationship is proportional, how many students would there be in a school with 32 teachers? Show your dimensional analysis
The number of students would there be in a school with 32 teachers is 32k.
What is meant by proportionality?In general, proportion refers to a part, share, or amount considered in comparison to a whole. According to the definition of proportion, two ratios are in proportion when they are equivalent. It is a formula or statement that shows that two ratios as well as fractions are equal.A proportion formula is just an equation that may be solved to determine the values to compare. We use the concept of proportion to solve proportion problems, which is two ratios that really are equal to each other.As the number of students are proportional to number of teachers.
Thus,
students ∝ teachers
student ∝ 32
students = 32k
where, k is the constant of proportionality.
Thus, the total number of students will be 32 k.

A rectangular garden has an area of 46 1/2 square feet. If the garden is
7½ feet long, how many feet wide is it?
Answer:
The answer is 6 1/5 feet in width.
Step-by-step explanation:
Since the formula for area is wl or width x length, we can utilize our reversive property to find our width by dividing the Area we are given by our length, giving us the missing width in return. Dividing 46.5 square feet by 7.5 feet gives us 6.2 feet, or 6 1/5 feet.

The first quartile is the area within one standard deviation of the mean.
The second quartile is the area within two standard deviations of the mean.
The third quartile is the area within three standard deviations of the mean.
The first quartile is the mean of the lower half of the data below the median.
The second quartile is the median.
The third quartile is the mean of the upper half of the data above the median.
The first quartile is the minimum value.
The second quartile is the median.
The third quartile is the maximum value.
The first quartile is the median of the lower half of the data below the overall median.
The second quartile is the overall median.
The third quartile is the median of the upper half of the data above the overall median.
The first quartile is the area that contains the 25% of all values that are closest to the mean.
The second quartile is the area that contains the 50% of all values that are closest to the mean.
The third quartile is the area that contains the 75% of all values that are closest to the mean.
Quartile deviation in Statistics can be defined as the statistic that measures the dispersion. Here, the Dispersion is the state of getting dispersed or spread. Statistical dispersion means the extent to which numerical data is likely to vary about an average value. In other words, dispersion helps to understand the distribution of the data Suppose Q1 is the lower quartile, Q2 is the median, and Q3 is the upper quartile for the given data set, then its quartile deviation can be calculated using the following formula.
QD = (Q3 – Q1)/2
In the next section, you will learn how to calculate these quartiles for both ungrouped and grouped data separately.
For an ungrouped data, quartiles can be obtained using the following formulas,
Q1 = [(n+1)/4]th item
Q2 = [(n+1)/2]th item
Q3 = [3(n+1)/4]th item
Where n represents the total number of observations in the given data set.
Also, Q2 is the median of the given data set, Q1 is the median of the lower half of the data set and Q3 is the median of the upper half of the data set.
The given data is that is first quartile is lowest off 25% of the numbers and second quartile. It is between 0% and 50% of two median.

12x-4y=-20
a) solve for y if x=-2.
b) solve for y in general.
Answer:
a) if x = 2, y = -1
b) y = 5
Step-by-step explanation:
12x - 4y = -20 Let's substitute x = 2
12(-2) - 4y = -20 Multiply
-24 - 4y = -20 Add 24 to each side
-4y = 4 Multiply each side by -1
4y = -4 Divide by 4
y = -1
now to solve for y in general:
12x - 4y = -20 Subtract 12x
-4y = -20 - 12x Divide by -4
y = 5 + 3x Sub 0
y = 5 + 3(0)
y = 5

Interpret the quote in terms of what you have learned about essential and discretionary vacation expenses.
The interpretation of the above quotation in terms of what is essential and discretionary vacation expenses implies that there are some unnecessary vacation expenses while others are compulsory vacation expenses.
What are discretionary and nondiscretionary expenses?
Discretionary expenses refer to outflows that a person can avoid if they choose.
On the other hand, one cannot avoid nondiscretionary expenses after choosing a spending activity because they are necessary and compulsory.
An example of nondiscretionary expenses are taxes, the cost of meals, and utility expenses. An example of a discretionary outflow is charitable donations.
Thus, when Robert Louis Stevenson claims that he travels for travel's sake, not to achieve any purpose, the expenses he incurs on such a trip are discretionary. He can avoid them by choosing not to embark on vacations.

If Angela uses this schedule for 4 weeks, she will have practiced for 34.08 hours in total
How many hours will she have practiced in total?The given parameters are:
Monday = 1.4 hours
Tuesday = 2.12 hour
Saturday = 5 hours
Weeks = 4

A real estate agent works on 11% commission. What is her commission on house that she sold $346,000?
A real estate agent commission on the house that she sold $346,000 is $38,060.
Given that, a real estate agent works on 11% commission.
We need to find out what is her commission on the house that she sold $346,000.
What is the commission?The commission is a percentage of total sales as determined by the rate of commission. Commission=Rate of commission⋅Total sales. To find the commission on a sale, multiply the rate of commission by the total sales.
Now, the commission on the house=11% of 346,000
=11/100 × 346,000
=0.11 × 346,000
=$38,060
Therefore, a real estate agent commission on the house that she sold $346,000 is $38,060.

The sum of two numbers is 54. The sum of the smaller and 5 times the larger is 166. Find the numbers.
Answer:
smaller number is 26
larger number is 28
Step-by-step explanation:
This is a system of equations that we can solve by substitution. Let x = the smaller number and y the larger. The two equations are:
x + y = 54
x + 5y = 166
Solve the first equation for y and use that in the second equation.
y = 54 - x (we will plug this in for y in the second equation and solve that for x)
x + 5(54 - x) = 166
x + 270 - 5x = 166
-4x = 166 - 270
-4x = -104
x = 26
Plug this into x + y = 54 and solve for y
26 + y = 54
y = 54 - 26
y = 28
