Step-by-step explanation:
It says that they sold 40 scarves and hats at the Winter Festival, but it never told us exactly how many hats total and how many scarves total that they sold. So we leave it as "s+h=40" Next we have the price of the scarves and hats, not the numbers sold. Since the scarves cost $18 and the hats cost $14, we know that a certain amount of each equals $700. Since we don't know the exact number of each that were sold, we leave it at "18s+14h=700." Sorry if you got a bit lost.

already collected from a single source over the course of a week at regular intervals. The contractor wants to test samples

Answers
Answer:
Systematic sampling
Step-by-step explanation:
An EPA contractor needing to test the concentration of a substance in ten samples out seventy samples provided form a single source at regular time intervals.
For the contractor to effectively carry out the testing he has to employ a Non-probability system of sampling which is called Systematic sampling, because in systematic sampling we can assume the population size (x ) which in this case is 70 and the sample size( n ) to be 10
He will have to select ; ( x / n )^th of the sampling frame for best results

Answer:
k = 2.5
Step-by-step explanation:
So we start off with: 2.5(4k+2) = 12k
Let's first distribute.
10k + 5 = 12k
Now let's subtract 10k from both sides.
5 = 2k
Now let's divide both sides by 2.
2.5 = k

Step-by-step explanation:
1.) 12-2/3x=48
2.) Multiple by 3 on both sides
36-2x=144
3.) Move the constant on the other side by subtracting it.
-2x=144-36

If pqrs is a parallelogram, find the measure of
113
5.67
18
67
Answers
Answer:
∠PSR = 113°
Step-by-step explanation:
Two angles in a parallelogram that are next to each other are supplementary. That means that they add up to 180°, so 7x-13+4x-5 = 180. Solve for x.
7x-13+4x-5=180
11x-18=180
11x=198
x=18
Now plug x back into the angle that opposite from the one you are looking for (they are equal)
7(18)-13 = ∠PSR
126-13 = ∠PSR
113 = ∠PSR
y varies inversely as X. y=4 when x=2. Find y when x=16
Answers
Answer:
y = 32 (Verified Answer) ✅Step-by-step explanation:
We will use a proportion to solve this.
[tex]\frac{2}{4} = \frac{16}{y}[/tex]
Now, we cross multiply.
2y = 16 x 4
2y = 64
Now, we must divide by 2 to get the correct value for y
y = 64/2
y = 32
Now, we can use the same proportion to check our answer.
2(32) = 16 x 4
64 = 64 ✅

y = 8/x = 8/16 = 1/2
y is 1/2 when x = 16.

Can you find the slope-intercept of the line? Thank you!
Answers
Answer:
y = x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (0, 2) ← 2 points on the line
m = [tex]\frac{2-0}{0+2}[/tex] = [tex]\frac{2}{2}[/tex] = 1
The line crosses the y- axis at (0, 2) ⇒ c = 2
y = x + 2 ← equation of line

Answer: [tex]6x^2y^3[/tex]
Explanation:
The numbers 2 and 3 multiply to 6, so that's why the final coefficient is 6.
The x terms multiply to [tex]x*x = x^2[/tex]
The y terms multiply to [tex]y*y*y = y^3[/tex]
The exponent tells us how many copies of the base to multiply.
So overall, [tex]2*x*x*3*y*y*y = 6x^2y^3[/tex]

y = 1/3x + 5
Step-by-step explanation:
y - y1 = m(x - x1)
y - (4) = 1/3(x - (-3)
y - 4 = 1/3(x + 3)
y - 4 = 1/3x + 1
y = 1/3x + 1 + 4
y = 1/3x +5

Find the value of k given that both points lie on a line passing through the origin.
(k,−24) and (5,40)
PLEASE HELP ASAP if you do thank u and have a blessed day
Answers
Answer:
[tex]k=-3[/tex]
Step-by-step explanation:
Since the line passes through the origin, it must be a proportional/direct variation equation.
Direct variation equations have the form:
[tex]y=ax[/tex]
Where a is the constant of proportionality.
Let’s solve for a. We know that when x=5, y=40. So:
[tex]40=5a[/tex]
Divide both sides by 5:
[tex]a=8[/tex]
Therefore, our equation is:
[tex]y=8x[/tex]
We want to find the value of k such that y=-24. So, subsitute -24 for y and k for x:
[tex]-24=8k[/tex]
Divide both sides by 8:
[tex]k=-3[/tex]
Hence, the value of k is -3.
