Answer:
A. 1.88
Step-by-step explanation:
In less fancy terms, a constant of proportionality is essentially a rate of change - or more specifically, a unit rate.
It's the number we multiply our independent variable by to get the y. You can find this by simply dividing the y value by the x value!
Let's choose the first order pair (2, 3.76).
[tex]3.76 \div 2 = 1.88[/tex]
We can check that this table IS constant by doing the same with the other values... we should always get 1.88!
[tex]7.52 \div 4 = 1.88\\9.40 \div 5 = 1.88\\15.04 \div 8 = 1.88[/tex]
This is true for all values - which means our constant is 1.88

In a scatterplot what does the term outlier mean?
Answers
Answer:
An outlier is defined as a data point that emanates from a different model than do the rest of the data. ... If the outlier is omitted from the fitting process, then the resulting fit will be excellent almost everywhere (for all points except the outlying point).
An outlier for a scatter plot is the point or points that are farthest from the regression line. ... If a number of points are the same farthest distance from the regression line, then all these points are outliers. If all points of the scatter plot are the same distance from the regression line, then there is no outlier.

[tex]x = 110 \\ (exterio \: angles \: of \: a \: traingle \: sum \: up \: to \: 360)[/tex]
Answer:
x = 110
Step-by-step explanation:
Assuming you require the value of x
The sum of the external angles of a triangle = 360°
The 3 angles shown are external angles.
Subtract the sum of the 2 given angles from 360 for x
x = 360 - (140 + 110) = 360 - 250 = 110
157 is 16.6% of what number
Answers
157 = .166 x
157/0.166 = x
945.78313253 = x
157 is 16.6% of 945.78313253, which rounds to 946.
The 157 is approximately 16.6% of 945.78313253012 rounded to the nearest decimal place.
To find the number that 157 is 16.6% of, set up the following equation:
16.6% = 0.166 (since percentages expressed as decimals)
0.166 × x = 157
To isolate x, we divide both sides of the equation by 0.166:
x = 157 / 0.166
Simplifying the division:
x ≈ 945.78313253012

Which equation can be used to represent k, the number of kilometers Julissa runs in t minutes?
k – 2 = k minus 2 equals StartFraction 1 Over 9 left-parenthesis t minus 18 right-parenthesis.(t – 18)

Answers
Answer:
$150, $575, y=150x+575
Step-by-step explanation:
hi! the first answer is $150 because the slope is the change in y values divided by the change in x values.
(1625-1175)/3 = 150
the second answer is $575 because the y-intercept is the y value at x=0. the savings amount increases by 150 every month, so to get to 0, we multiply 150 by 4, which is 600. we subtract this from 1175, which is 575.
the third answer is y=150x+575 because the initial amount (y-intercept) is 575 so it is constant, and it increases by 150 every month (therefore accompanied by a variable).

b. What total amount did he have to spend during the week?
c. What was his balance at the end of the week?
( please do not comment if you do not know the answer, would be appreciated )
Answers
Answer:
Step-by-step explanation:
a-As he had earned $45.00 for cutting lawns and had earned $35.75 for yard work during the week and had not earned more than that, in order to find the total amount of money he earned during the week, we have to add $45.00 and $35.75 together which will be $80.75. So we can say that he had earned $80.75 during the week.
b- Since he had spent $25.23 on food and $22.12 on gas, we have to add them to get the total amount of money spend during the week. So after adding the amount of moneys spent, we will get $47.35.
c- Finally, to find out how many money he was left with, we have to subtract the amount of moneys spent from the total amount of earnings for the week. So, after subtracting $47.35 from $80.75 he is left with $33.4.

Liam rented a pedal board for 5.5 hours and paid a total of $93.75. What is an equation in point-slope form that
models the cost of renting a pedal board for x hours? How can Liam use the equation to find the one-time service
charge?
Answers
Answer: if y is the total cost of the rental, then y-93.75=12.5(x-5.5) models the cost of renting a pedal board for x hours. liam should rewrite the equation from the previous step so that y is isolated on one side. the constant on the other side is then the service fee.
Step-by-step explanation:
yeah that’s all
The point-slope form equation is an equation that has a slope "m" and passes through a point or two points.
The equation to find the one-time service charge is 93.75 = 17.05x + b
The point-slope form equation is written as:
y = mx + b
Where
m = gradient
b = slope of the line
Liam rented a pedalboard for 5.5 hours and paid a total of $93.75.Therefore, the cost of renting a pedalboard for 1 hour
= $93.75/5.5
= $17.05
a) An equation in a point-slope form that models the cost of renting a pedal board for x hours is written as:y = mx + b
Where
y = Total charge = $93.75
m = Cost of renting a pedalboard per hour = $17.05
x = Number of hours for renting a pedal board
Hence, the equation is given as:
93.75 = 17.05x
b)The equation to find the one-time service charge where the service charge is b is given asHence, the equation is given as:
93.75 = 17.05x + b
Where b = service charge
