A fixed ratio schedule is a type of reinforcement schedule in which a response is reinforced after a specific number of responses. In this case, the response of putting money in the machine is reinforced after every 1 response.
If each time you put a dollar in a vending machine you get a snack, then your response is reinforced according to a fixed ratio schedule.
Variable interval, fixed interval, and variable ratio schedules are all different types of reinforcement schedules that are based on different criteria. A variable interval schedule is a type of reinforcement schedule in which a response is reinforced after a random interval of time. A fixed interval schedule is a type of reinforcement schedule in which a response is reinforced after a fixed interval of time. A variable ratio schedule is a type of reinforcement schedule in which a response is reinforced after a random number of responses.

How do you find the y-intercept of a standard form equation?
Answer:
Step-by-step explanation:
ok so standard form is
Ax+By=C
and its actually really simple
when you want to find the y-intercept
set x to 0
it will look something like
A(0)+By=C
By=C
y=C/B
It makes more sense with actual numbers
so
3x+2y=4
3(0)+2y=4
0+2y=4
2y=4
y=2
therefore the y intercept would be 2
for that equation
but you can do the same for x-intercept
just set y to 0
hope this helped :)
Find the slope-intercept form that passes through (2,-2) and (-4,1)
Answer:
y=1/2x+1
Step-by-step explanation:
I think so I'm not an expert
Answer:
y = - [tex]\frac{1}{2}[/tex] x - 1
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, - 2 ) and (x₂, y₂ ) = (- 4, 1 )
m = [tex]\frac{1-(-2)}{-4-2}[/tex] = [tex]\frac{1+2}{-6}[/tex] = [tex]\frac{3}{-6}[/tex] = - [tex]\frac{1}{2}[/tex] , then
y = - [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (2, - 2 ) , then
- 2 = - 1 + c ⇒ c = - 2 + 1 = - 1
y = - [tex]\frac{1}{2}[/tex] x - 1 ← equation of line
Use the following table to answer questions (a – c). x 1 2 3 4 7 8 10 y 9 7 6 1 -2 -5 -8 . b. Calculate the correlation coefficient. c. Based on your calculation in part (b) describe the correlation between the x and y. Explain your reasoning.
b. The correlation coefficient for this data-set is given as follows: r = -0.9877.
c. The correlation between the variables x and y is strong negative.
What is the correlation coefficient and how to obtain it?The correlation coefficient is an index between -1 and 1 that measures the relationship between two variables, as follows:
negative coefficient: inverse relationship.positive coefficient: direct relationship.absolute value greater than 0.6: strong relationship.absolute value less than 0.6: weak relationship.A data-set is composed by a set of points, and these points are inserted into a correlation coefficient calculator to obtain the coefficient.
From the table described in this problem, the points are given as follows:
(1, 9), (2, 7), (3,6), (4, 1), (7, -2), (8, -5) and (10, -8).
Inserting these points into a calculator, the coefficient is given as follows:
r = -0.9877.
Hence it is a negative and strong relationship, as the absolute value of r is of 0.9877 > 0.6.

What is line of reflection ?
The picture is consistent with the preimage when reflecting a figure in a line or a point. Every point on a figure is translated into an image by a reflection across a set line. The term "line of reflection" refers to the fixed line.
The line of reflection is a line across which an image will reflect. Every point in a figure is said to reflect the other figure if and only if it is equally spaced from every corresponding point in the other figure. The image that is reflected should be identical in size and shape but face the opposite way.
Graph the quadrilateral. By inspection, you can tell where the midpoint is. (see attachment 1)
Now, I'll draw a line through it. (see attachment 2)
To reflect across a line, think about the points traveling across the line the same number of spaces the point is from the line. For example, point A is three away from the line. So, A' will be 3 away from the other side. The coordinates will be at (-3,2). (see attachment 3).
Do the same for the other points, and you'll have your image.

What is the double integral?
A multiple integral is a definite integral of a function of several real variables, for instance, f or f.
1. Φ(u,v) gives the parametrization with its x, y, and z components. So, x=7u+4, y=u-v, and z=13u+v.
We can use this to get the tangent vectors by taking the respective partial derivatives.
Tu=<7, 1, 13> by taking the u derivatives of the components, and Tv=<0, -1, 1> by taking the v derivatives of the components.
2. Taking the cross product of Tu and Tv will give the normal vector n(u,v), which is <14, -7, -7>.
3. To find Area(S), you have to multiply the area of D by the magnitude of the normal vector from the previous step. D is the region defined by 0<=u<=5 and 0<=v<=6, so the area of D is 5*6=30.
Multiply this by the magnitude of the normal vector to find that Area(S)=30√(294)
Area(S) = 514.39
4. To integrate, we first must put the initial function in terms of the parameters we found in the first step.
Replace y with u-v and z with 13u+v. Next, multiply this integrand by the magnitude of the normal vector (√294) and apply the given bounds for u (0<=u<=5) and v (0<=v<=6).
From here the problem can be integrated like any other double integral, the final answer being 190√(294).
Hence, The final solution is:
(1) Tu=<7, 1, 13>, Tv=<0, -1, 1> and n(u,v)=<14, -7, -7>.

a spherical balloon is being filled with air at a constant rate of . at what rate is the surface area increasing when the volume is
The surface area of a sphere is given by the formula 4πr^2, where r is the radius of the sphere. This means that the surface area of the balloon is increasing at the rate of 8πr cm^2/sec.
The volume of a sphere is given by the formula 4/3πr^3, where r is the radius of the sphere. If the radius of the balloon is 6 cm, then the volume of the balloon is (4/3)π(6^3) = (4/3)π216 = 288π cm^3.
To find the rate at which the volume of the balloon is increasing, we need to take the derivative of the formula for the volume of a sphere with respect to time. This gives us (4/3)π(3r^2)(dr/dt).
Since the radius of the balloon is 6 cm and the surface area of the balloon is increasing at the rate of 8πr cm^2/sec, the rate at which the radius of the balloon is increasing is (8πr/4πr^2) = 2/r = 2/6 = 1/3 cm/sec.
Plugging this into the formula for the rate of change of the volume of the sphere, we get
(4/3)π(3r^2)(dr/dt) = (4/3)π(36^2)(1/3) = (4/3)π108 = 144π cm^3/sec.Therefore, the volume of the balloon is increasing at a rate of 144π cm^3/sec when the radius of the balloon is 6 cm.

To calculate how much Kaitlyn will have after four years with continuous compounding, we can use the following formula:
A = P * e^(r*t)
where A is the final amount, P is the initial principal (in this case, $3,000), r is the annual interest rate (4.08%), and t is the number of years (4). Plugging these values into the formula, we get:
A = $3,000 * e^(0.0408*4)
= $3,000 * e^0.1632
= $3,000 * 1.1759
= $3,527.77

Find the area enclosed by the curve x 3t, y t and the y-axis. Step 1 The curve x = t2-3t, y = Vt intersects the y-axis when x = 0, which occurs when t = 0 and 3 3 H 3 '
The area enclosed by the curve x = t^2 − 3t, y = √t and the y-axis is 2.08 square units.
We have been given parametric equations x = t^2 − 3t, y = √t
We need to find the area enclosed by the curve x = t^2 − 3t, y = √t and the y-axis.
Consider x = 0
So, t^2 − 3t = 0
t(t - 3) = 0
t = 0 or t = 3
Let f(t) = t^2 − 3t and g(t) = t
Differentiate the curve f(t) with respect to t.
f'(t) = 2t - 3
NWe know that the formula to find the area under the curve.
A = ∫[a to b] g(t)f'(t) dt
here, a = 0 and b = 3
so, A = ∫[0 to 3] √t (2t - 3) dt
A = ∫[0 to 3] (2t√t - 3√t) dt
A = ∫[0 to 3] (2t^(3/2) - 3t^(1/2)) dt
A = [4/5 t^(5/2) - 2 t^(3/2)]_[t = 0, t = 3]
A = 4/5 3^(5/2) - 2 3^(3/2) - 0 + 0
A = 4/5 3^(5/2) - 2 3^(3/2)
A = 6√3 /5
A = 2.08
Therefore, the area of the curve is 2.08 square units.

Three friends are down loading music from a web site. Dean pays £18.13 to down load 3 albums and 4 single tracks. Becky pays £13.93 to down load 2 albums and 5 single tracks. Charlotte wants to download 4 albums and 3 single he tracks. How much will Charlotte be charged? (You may use a calculator)
Answer:
£22.33
Step-by-step explanation:
calculate the cost of an album and a single track using simultaneous equations.
let a represent an album and s a single track , then
3a + 4s = 18.13 → (1)
2a + 5s = 13.93 → (2)
multiplying (1) by - 2 and (2) by 3 and adding will eliminate a
- 6a - 8s = - 36.26 → (3)
6a + 15s = 41.79 → (4)
add (3) and (4) term by term to eliminate a
0 + 7s = 5.53
7s = 5.53 ( divide both sides by 7 )
s = 0.79
substitute s = 0.79 into either of the 2 equations and solve for a
substituting into (1)
3a + 4(0.79) = 18.13
3a + 3.16 = 18.13 ( subtract 3.16 from both sides )
3a = 14.97 ( divide both sides by 3 )
a = 4.99
that is album costs £4.99 and single track £0.79
then cost to Charlotte is
cost = (4 × £4.99) + (3 × £0.79) = £19.96 + £2.37 = £22.33
The cost of 4 albums and 3 single tracks is £22.33
Let the cost of 1 album = £x
and let the cost of 1 single track = £y
Now, the cost of 3 albums and 4 single tracks = £3*x + £4*y
and cost of 2 albums and 5 single tracks= £2*x + £5*y
Given that,
£3*x + £4*y = £18.13 -------->(1)
£2*x + £5*y = £13.93 -------->(2)
Multiply (1) equation by 2 and (2) equation by 3 then solve for x and y.
On applying the substitution method we have,
x = £4.99 and y = £0.79
Now, we have to calculate the value of 4 albums and 3 single tracks.
It can be written as 4*x +3*y
£4*4.99 + £3*0.79 = £22.33
So, the cost of 4 albums and 3 single tracks is £22.33

f(x)= 0
The x-intercepts are also called zeros or roots of the function, and are the points where the graph of the function intercepts the x-axis.
In this case, the function is g(x) = -3x + 9, so here we need write and solve the equation:
g(x) = 0
-3x + 9 = 0
9 = 3x
9/3 = x
3 = x
This means that the x-intercept is x = 3, or (3, 0) written in point form, when we evaluate g(x) in x = 3 we get:
g(3) = -3*3 + 9
g(3) = -9 + 9
g(3) = 0
As expected.

What is a contour map?A contour map, which is also called a topographic map, is a representation of a three-dimensional feature using contour lines on a plane surface.
The map shows a bird's-eye view and allows people to visualize the hills, valleys, and slopes that are being mapped.
People can see the hills, valleys, and slopes that are being mapped thanks to the map's bird's-eye perspective.
The title, scale, contour interval, legend, and whether latitude and longitude or Universal Transverse Mercator (UTM) coordinates are used are typically included.
Numerous activities, such as camping, urban planning, meteorology, and geologic investigations, can benefit from using this kind of map.
Consider the surface [tex]$f(x, y)=\ln \left(x^2+4 y^2\right)$[/tex].
The level curves for the surface are given by the equation, [tex]$k=\ln \left(x^2+4 y^2\right)$[/tex], where [tex]$k \in \mathbb{R}$[/tex]
Take k = . . . , -3, -2, -1, 0, 1, 2, 3, . . .
Then, draw the different level curves of the surface.
