The probability of selecting a skirt and a top is calculated as follows:
(number of skirts)/(number of choices for the bottom) x (number of tops)/(number of choices for the top).
How to calculate a probability?A probability is calculated as the division of the desired number of outcomes by the total number of outcomes.
The probability of choosing the skirt is obtained dividing the number of skirts available by the total number of choices for the bottom, such as jeans and so on, hence:
(number of skirts)/(number of choices for the bottom)
The probability of choosing a top is obtained with the same logic, as follows:
(number of tops)/(number of choices for the top).
Hence the probability of choosing both a skirt and a top is given as follows:
(number of skirts)/(number of choices for the bottom) x (number of tops)/(number of choices for the top).
Missing InformationThe problem is incomplete, hence the probability was calculated in general terms.

The statement "Multiple linear regression allows for the effect of potential confounding variables to be controlled for in the analysis of a relationship between x and y" is True
What is multiple linear regression ?Multiple linear regression serves as a statistical technique to investigate the connection between a dependent variable (y) and multiple independent variables (x1, x2, x3, etc.). By embracing several variables concurrently, it enables the examination to incorporate and account for potential confounding variables, thereby enhancing the accuracy of the analysis.
Confounding variables represent variables that exhibit associations with both the independent variable and the dependent variable. This coexistence may lead to a misleading or distorted relationship between the two.

Answer:
y = \(-\frac{1}{2}\)x + 1
Step-by-step explanation:
y = mx + c
Find the reciprocal and change the sign of the gradient (m), which is -\(\frac{1}{2}\)
so
y = \(-\frac{1}{2}\)x + c
Put in your point that you want it to intersect (4,-1):
-1 = \(-\frac{1}{2}\)(4) + c
-1 = -2 + c
-1 + 2 = c

On a camping trip you bring 12 items for 4 dinners. For each dinner you use 3 items. In how many ways can you choose items for the first dinner? for the second? for the third? for the fourth?
Answer:
ermmm...yeah
Step-by-step explanation:
Since you bring 12 items for 4 dinners, you have a total of 12 items to choose from.
For the first dinner, you need to choose 3 items out of the 12. You can do this in:
12 choose 3 = (12!)/(3!*(12-3)!) = 220 ways
For the second dinner, you have used up 3 items in the first dinner, so you have 9 items left to choose from. You need to choose 3 items out of the 9. You can do this in:
9 choose 3 = (9!)/(3!*(9-3)!) = 84 ways
For the third dinner, you have already used up 6 items, so you have 6 items left to choose from. You need to choose 3 items out of the 6. You can do this in:
6 choose 3 = (6!)/(3!*(6-3)!) = 20 ways
For the fourth dinner, you have already used up 9 items, so you have only 3 items left to choose from. You need to choose all 3 items. You can do this in:
3 choose 3 = (3!)/(3!*(3-3)!) = 1 way
Therefore, you can choose items for the first dinner in 220 ways, for the second dinner in 84 ways, for the third dinner in 20 ways, and for the fourth dinner in 1 way.

A robot moves in the positive direction along a straight line so that
after t minutes its distance is s=6t^(4) feet from the origin. (a) Find
the average velocity of the robot over the interval 2,4. (b) Find the
instantaneous velocity at t=2.
The robot moves in the positive direction along a straight line so that after t minutes its distance is s=6t^4 feet from the origin. (a) Find the average velocity of the robot over intervals 2, 4. We have the following data: Initial time, t₁ = 2 min.
Final time, t₂ = 4 min.The distance from the origin is given by s = 6t^4Therefore, s₁ = s(2) = 6(2^4) = 6(16) = 96 feet s₂ = s(4) = 6(4^4) = 6(256) = 1536 feet
We can find the average velocity of the robot over the interval 2, 4 as follows: Average velocity = (s₂ - s₁) / (t₂ - t₁)Average velocity = (1536 - 96) / (4 - 2)Average velocity = 1440 / 2Average velocity = 720 feet per minute(b) Find the instantaneous velocity at t=2.To find the instantaneous velocity at t = 2 min, we need to take the derivative of the distance function with respect to time. We have the distance function as:s = 6t^4 Taking derivative of s with respect to t gives the velocity function:v = ds / dt Therefore,v = 24t³At t = 2, the instantaneous velocity is:v(2) = 24(2)³v(2) = 24(8)v(2) = 192 feet per minute Therefore, the instantaneous velocity at t = 2 min is 192 feet per minute.

The data in the table shows a sinusoidal relationship between the number of seconds an object has been moving and its velocity v (x), measured in centimeters per second
What is true of the cosine function that models the data in the table?
Drag a value into each box to correctly complete the statements.
The period of the cosine function is The equation of the midline of the cosine function is y = 20 The amplitude of the cosine function is
Answer:
The period is the change in x required for the function to return to the same value, changing in the same direction. The first two table entries are v(x) = 41.7 and 35.7. The next time that sequence appears is when x=44, so the period is ...
period = 44 -4 = 40 . . . seconds
__
The minimum table value is 20; the maximum is 44, so the midline of the function is their average:
midline = (20 +44)/2 = 32
__
The amplitude is the maximum deviation from the midline, so is ...
amplitude = 44 -32 = 12
Step-by-step explanation:
find the net outward flux of far across any smooth closed surface in r3, where a is a constant nonzero vector and rx,y,z.
The net outward flux of F across any smooth closed surface can be found by evaluating the triple integral of ∇ · F over the region enclosed by the surface.
To find the net outward flux of a vector field F across any smooth closed surface in \(R^3\), we can use the divergence theorem. The divergence theorem states that the net outward flux of a vector field F across a closed surface S is equal to the triple integral of the divergence of F over the region enclosed by S.
Mathematically, the net outward flux can be expressed as:
∫∫∫V ∇ · F dV
where V represents the region enclosed by the closed surface S, ∇ · F is the divergence of the vector field F, and dV is the volume element.
In the given case, let's assume that F represents the vector field in \(R^3\), and a is a constant nonzero vector. The net outward flux of F across any smooth closed surface can be found by evaluating the triple integral of ∇ · F over the region enclosed by the surface.
Note: The specific expression for ∇ · F depends on the vector field F. Without the explicit form of F, it is not possible to provide a more detailed calculation.

Step-by-step explanation:

A. multiply through by the L.C.M (4).
solve the problem the width of a rectangle is 4 feet less than its length. find the length and width if the area is 96 ft2
According to the formula for the area of a rectangle, which is A = l x w, where A is the area, l is the length, and w is the width. The length of the rectangle is 12 feet and the width is 8 feet.
To solve this problem, we can use the formula for the area of a rectangle, which is A = l x w, where A is the area, l is the length, and w is the width.
We know that the area of the rectangle is 96 ft^2, so we can plug that in for A:
96 = l x w
We also know that the width is 4 feet less than the length, so we can write:
w = l - 4
Now we can substitute this expression for w into our equation for the area:
96 = l x (l - 4)
Expanding the right side, we get:
96 = l^2 - 4l
Rearranging this equation, we get a quadratic equation in standard form:
l^2 - 4l - 96 = 0
We can solve this equation by factoring or using the quadratic formula, but in this case, it's easier to factor:
(l - 12)(l + 8) = 0
This gives us two possible values for l: l = 12 or l = -8. Since the length of a rectangle can't be negative, we discard the second solution and conclude that the length of the rectangle is 12 feet.
To find the width, we can use the equation we had earlier:
w = l - 4
Substituting l = 12, we get:
w = 12 - 4 = 8
Therefore, the length of the rectangle is 12 feet and the width is 8 feet.
