Answer:
Step-by-step explanation:
1.
(im gonna use x as a variable for all of these problems)
first to find how much each square foot costs subtract 80 from the total first
287 - 80 = 207
then divide $207 between 60 square feet
207 / 60 = $3.45
so each square foot is $3.45
our equation to find the cost would be
y = 3.45x + 80
2.
first lets find out how much the scarves are
5 x 12 = $60
then subtract that from the total
125 - 60 = $65
for 5 sister to each have 2 pairs of socks that means theres 10 pairs of socks
divide ypur rmaining money by the 10 pairs
65 / 10 = $6.50
so each pair of socks is $6.50
3.
first lets make an equation for the ymca costs
y = 15x + 20
then plug in 185 for y
185 = 15x + 20
solve for x
165 = 15x
11 = x

The graph of a line on a coordinate plane has a slope of 1/2 and passes through the point (4, -3). Which equation describes the line?
Answer:
[tex]\boxed {\boxed {\sf y= \frac{1}{2}x-5 }}[/tex]
Step-by-step explanation:
Since we are given a point and a slope, we should use the point-slope equation.
[tex]y-y_1=m(x-x_1)[/tex]
where m is the slope and (x₁, y₁) is the point the line passes through.
We are given the slope of 1/2 and the point (4, -3). Therefore:
[tex]m= \frac{1}{2} \\x_1= 4\\y_1= -3[/tex]
Substitute the values into the formula.
[tex]y--3= \frac{1}{2} (x-4)[/tex]
[tex]y+ 3= \frac{1}{2} (x-4)[/tex]
Distribute the 1/2. Multiply each term inside the parentheses by 1/2.
[tex]y+3= \frac{1}{2} *x + \frac{1}{2} * -4[/tex]
[tex]y+3=\frac{1}{2}x-2[/tex]
We want to the equation of the line in slope-intercept form or y=mx+b. We need to isolate y. 3 is being added and the inverse of addition is subtraction. Subtract 3 from both sides of the equation.
[tex]y+3-3=\frac{1}{2}x-2-3[/tex]
[tex]y=\frac{1}{2}x-2-3\\y= \frac{1}{2}x-5[/tex]
The equation of the line is y=1/2x-5

Jackets cost $15 and a set of decorative buttons cost $5. The delivery fee is $5 per order. The expression 15n+5n+5 gives the cost, in dollars, of buying jackets with buttons for n people. Write this expression after combining like terms. *
Answer: 20n + 5
Step-by-step explanation:
From the question, we are told that jackets cost $15 and a set of decorative buttons cost $5 and that the delivery fee is $5 per order.
The expression 15n+5n+5 gives the cost, of buying jackets with buttons for n people. The expression after combining like terms would be:
= 15n + 5n + 5
= 20n + 5

Answer:
Perimeter: 52 Area: 181-16i?
Step-by-step explanation:
Perimeter
The formula for perimeter is 2l+2w, so you plug in the binomials they give you:
2(11-4i)+2(15+4i)
expand:
22-8i+30+8i
combine like terms (which cancels out 8i and -8i):
22+30=52
Area
"i" is not a real number and thus should not be part of the area here, meaning this answer as it is is wrong and I don't know how one would change that.
Here's what I did to get 181-16i, in any case:
The formula for area is l*w, so I plugged in the numbers:
(11-4i)(15+4i)
expanded:
165+44i-60i-16i*i
and combined like terms:
181-16i
*i is [tex]\sqrt{-1}[/tex], so [tex]i^{2}[/tex]=-1 and -1*-16=16.

Leo reads 14 pages in 1/2 hour. What is the unit rate for pages per hour? For hours per page?
Answer:
1:28 | 1:1/28
Step-by-step explanation:
We can show the first two numbers as a ratio:
14:1/2
But we want that second number to be 1 so we can multiply by 1:
28:1 <------ Pages per hour
But now we need the left to be 1, so we divide by 28:
1/28:1
Then flip:
1:1/28

Answer:
1. Trinomial 2. Trinomial 3. Monomial 4. Binomial 5. Binomial
Step-by-step explanation:
The numbers with variables attached are called terms, and how many there are defines the equation. It doesn't matter how many variables or exponents are attached, there could be none or 15 each to the power of 6 but it's still one term. "Mono" means one, so there's only one term, "Bi" means two, so there are two terms, and "Tri" means three, so there are three terms. "Poly" applies to everything above three, though unused words for the bigger terms do exist.

Complete the statements by filling in the blank. When constructing a confidence interval, to increase the level of confidence, you must ________ [increase/decrease] the margin of error and the confidence interval will be _________ [narrower/wider]. A larger sample size will improve the precision of the confidence interval, therefore, all things being equal, a larger sample size will result in a __________ [smaller/larger] margin of error and the confidence interval will be _________ [narrower/wider].
Answer:
Increase; wider; smaller; narrower.
Step-by-step explanation:
In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.
A confidence interval can be defined as a measure of the number of times that a population parameter would be within a given set of data. Thus, it is an estimate of the uncertainty of a given statistical data.
When constructing a confidence interval, to increase the level of confidence, you must increase the margin of error and the confidence interval will be wider. A larger sample size will improve the precision of the confidence interval, therefore, all things being equal, a larger sample size will result in a smaller margin of error and the confidence interval will be narrower.
Hence, for an estimator to be consistent it must have both a small bias and small variance.

Consider this quadratic equation:
2x2+12=0
Comparing it to the standard form, name a, b, and c
a=
b=
c=
Answer:
a=2
b=0
c=12
Step-by-step explanation:
The standard form of a quadratic equation is ax²+bx+c=0
Here's the given equation:
2x²+12=0
You might notice that the term bx is not there (there is just ax² and c). That means that b is 0.
The term 2x² is the term ax² in this equation. The coefficient in the term is 2, so that means that a is 2
12 has no variable, so that means it'll be c in the equation.
Hope this helps!
Plz help I don’t understand how to find x?
Answer:
x = -4
Step-by-step explanation:
First lets add 82 + 55 which equals 137, then 137 +47 which equals 184
Now we know that a triangle equals 180 degrees (cannot go over 180), so this tells us x is a negitive number.
-x + 184 = 180
-x = -4
Another way to look at it is; 184 minus what equals 180? 4 does, so it translates into -4.

How many solutions does this system of equations have? y=3x+1 y=3x+7
Answer:
The following system of equation has no solution.
Step-by-step explanation:
since both of them are equal to y, set them equal to each other:
3x+1=3x+7
if you subtract both sides by 3x, you get 1=7. That is a contradiction, so this has no solutions.
This equation has no solution.
What is the inconsistent system?An inconsistent system is a system that has no solution in any case scenario.
Given this system of equations y=3x+1, y=3x+7.
on comparing both equations multiples of x and y are equal therefore, there will be no solution for a given equation.
