Answer:

z= 117°

y = 34

Hope it helps!

Step-by-step explanation:

(5y - 53) + 63 =180°

5y + 10 =180

5y = 170

y= 34

z and y are congruent (vertical angles)

5 (34) - 53 = z

170 - 53 = z

z = 117

The color of the origin (0, 0, 0) is green.

To determine the color of the origin (0, 0, 0) using the k-nearest neighbors algorithm with k equals 3 and the distance function d((z1, z2, z3), (w1, w2, w3)) = Σ|i=1 to 3| |zi - wi|.

we need to find the three nearest neighbors to the origin based on the given training data set.

Calculating the distances between the origin and each observation:

The three nearest neighbors to the origin are observations 2, 5, and 6, with distances of 2, 2, and 3, respectively.

Among these neighbors, two are green and one is red. Since green has a higher count, the color of the origin (0, 0, 0) would be **green**.

A rational equation is defined as the quotient of two polynomials, with the denominator not being zero. It is a type of algebraic expression that involves variables and rational functions with rational exponents.

The error in the given rational equation is that it's not allowed to cancel out the x-2 and X+2 terms, as they are in the denominators. It is because of the fact that it may make the denominator zero, which would result in undefined expressions. Therefore, we need to find the least common multiple (LCM) of the denominators and then convert the equation into equivalent forms with the same denominator.B):

Step-by-step explanation:

The joint probability density function (joint pdf) is a function used to characterize the probability distribution of multiple continuous random variables that together form a continuous random vector. The results of asking values are

a) E(X³) = 5.86

b)E(X/Y = 2) = 2

c) E(Y²) = 1.2

d) σᵧ= 0.7483

e) E(3Y) = 2.4

We are given that X, Y denotes the number of students and number of questions respectively.

P(X,Y) denote the joint probability mass function for X and Y. Also provide,

P(0,0)=0.04, P(1,0)=0.16, P(1,1)=0.1, P(2,0)=0.2, P(2,1)=0.3, P(2,2)=0.2.

Therefore the required quantities here are computed as:

P(X = 0) = 0.04

P(X = 1) = 0.26

P(X = 2) = 0.7

a) E(X³) = 0 + 1×0.26 + 23×0.7

= 5.86 is the required value here.

b) Now given Y = 2, the conditional Probability density function for X here is obtained as:

P(X = 2 | Y = 2) = 1

Therefore, E(X | Y = 2) = 2 here.

c) For Y, we have here:

P(Y = 0) = 0.4

P(Y = 1) = 0.4

P(Y = 2) = 0.2

Therefore,

E(Y²) = 0.4×1 + 22×0.2

= 1.2 is the required value here.

d) The standard deviation of Y here is computed as:

E(Y) = 1×0.4 + 2×0.2 = 0.8

S.D(Y) = sqrt( E(Y²) - [E(Y)]²) = sqrt( 1.2 - 0.82 )

= 0.7483 is the required value here.

e) E(3Y) = 3E(Y) = 3×0.8

= 2.4 is the required value here.

The probability that X > 1 and Y > 0 here is computed as:

= p( 2, 1). + p(2, 2) = 0.3 + 0.2 = 0.5 is the required probability.

Hence, we calculate all the required Probability values .

To divide fractions you need to do the reciprocal of the 2nd fraction and them multiply.

Eg. \(\frac{1}{3}\) ÷ \(\frac{2}{4}\)

This is the same thing as \(\frac{1}{3}\) ×\(\frac{4}{2}\)

Which equals \(\frac{4}{6}\) and if simplified, it will be \(\frac{2}{3}\)

So you don't need a common denominator to divide, you have to use the method showed above.

Answer:

The answer is A choice.

Explanation:

By looking at the graph, we notice that at the left side, the domain/x-value stops at -5 and 5.

Thus, the domain is at the left end side to the right end side.

The domain stops at -5 on the left side and 5 on the right side. Thus the answer is

-5 < x < 5.

The A choice.

Understanding

The domain of a function is basically all the values where x is defined, and by defined, it means it has a y value corresponding to it. In this graph, x is defined from -5 to 5. If you look outside this range of numbers (from -5 to 5 on the x-axis) you will not find any y values for them. We can easily say the solution is A.

Solution:

[A] \(-5<x<5\)

Note: From what I see from the picture -5 and 5 are included in the domain, either the question is incorrectly written, or the picture isn't clear enough. If so, the answer should be \(-5\leq x\leq 5\).

The x-intercept of CD is 17.

Since CD is perpendicular to AB and passes through point C(5, 12), we can find the equation of CD using the slope-intercept form.

The slope of CD can be determined using the negative reciprocal of the slope of AB.

Slope of AB = (change in y) / (change in x) = (14 - (-3)) / (7 - (-10)) = 17 / 17 = 1

The negative reciprocal of 1 is -1. Therefore, the slope of CD is -1.

Using the slope-intercept form, we can write the equation of CD as:

y - y1 = m(x - x1),

where (x1, y1) is a point on CD. Let's use point C(5, 12):

y - 12 = -1(x - 5)

Simplifying the equation, we have:

y - 12 = -x + 5

y = -x + 17

To find the x-intercept, we set y = 0 and solve for x:

0 = -x + 17

x = 17

Therefore, the x-intercept of CD is 17.

The area of the window is 49 10/12 square feet, which can be simplified to 49 5/6 square feet. The answer is (B) 49 5/6 ft2.

The internal angles of a rectangle, which has four sides, are all exactly 90 degrees. At each corner or vertex, the two sides come together at a straight angle. The rectangle differs from a square because its two opposite sides are of equal length.

The width of the window is 8 2/3 feet and the height is 5 3/4 feet. To find the area, we can simply multiply these two values:

Area = width × height

Area = (8 2/3 feet) × (5 3/4 feet)

First, we need to convert the mixed numbers to improper fractions:

8 2/3 = (8 × 3 + 2)/3 = 26/3

5 3/4 = (5 × 4 + 3)/4 = 23/4

Now, we can multiply the fractions:

Area = (26/3 feet) × (23/4 feet)

Area = (26 × 23)/(3 × 4) square feet

Area = 598/12 square feet

To simplify the mixed number, we can divide the numerator by the denominator:

598 ÷ 12 = 49 10/12

Therefore, the area of the window is 49 10/12 square feet, which can be simplified to 49 5/6 square feet. The answer is (B) 49 5/6 ft2.

The equation of the function is: H = 4t + 10.

The y-intercept of the function is 10, which is the height of the plant when Liam initially bought it.

To write the equation of a function, first, find the slope (m) = rise / run. You can pick any two points on the line to find the slope. Next, find the y-intercept (b) which is the point where the line intercepts the vertical axis of the graph.

Find the slope using the two points from the given graph, (5, 30) and (10, 50):

Slope (m) = change in H / change in t = (50 - 30) / (10 - 5) = 20/5

m = 4

The y-intercept is b = 10 [in this context, it is the height of the plant when Liam initially bought it]

This data would be considered "paired" data.

The population of ferrets from which our sample was drawn, represented as μd, where μd = μend - μstart, and μ represents the population mean.

       We are dealing with "paired" data since we are comparing the weights of the same ferrets at two different points in time.

      The parameter we are trying to estimate is the mean difference in weight between the start and end of the study for the population of ferrets from which our sample was drawn.

This mean difference in weight can be represented as μd, where μd = μend - μstart, and μ represents the population mean. To estimate this parameter, we would need to calculate the difference in weight for each ferret and then take the average of these differences. This estimate would then provide us with an understanding of how much, on average, the ferrets in the population have gained or lost weight over the course of the study.

The domain for the given function is {-1, 2, 33, 32}.

A function's or relation's domain is the set of all possible independent values that the relation can take. It is the sum of all possible inputs.

A function's or relation's range is the set of all possible dependent values that the relation can produce from the domain values. It is the sum of all possible outputs.

When dealing with sets of ordered pairs, we simply divide the pairs into x- and y-coordinates. The domain is formed by the x-coordinates, which are independent values. The y-coordinates are the dependent values, i.e. they define the range.The domain in the set of ordered pairs {(a,b); (c,d); (e,f); (g,h)} is the set of the first number in each pair (those are the x-coordinates): {a,c,e,g}. The range is the set of all the pairs with the second number (the y-coordinates): {b,d,f,h}.

Given,

The set of ordered pair =   {(-1,5) , (2,3), (33,6), (32,7)}

then,

the Domain = {-1, 2, 33, 32}

So the velocity vector is v = (-2sin(t)) i + (2cos(t)) j, and the acceleration vector is a = (-2cos(t)) i + (-2sin(t)) j, both in terms of t.

Given

r= 2cost and theta = 9t

To Find

the velocity and acceleration vector

Solution

We can start by expressing the position vector r in terms of the Cartesian coordinates x and y:

x = r cos(theta) = 2cos(t)

y = r sin(theta) = 2sin(t)

To find the velocity vector, we can take the time derivative of the position vector:

v = (dx/dt) i + (dy/dt) j

where i and j are the unit vectors in the x and y directions, respectively.

Taking the derivatives:

dx/dt = -2sin(t)

dy/dt = 2cos(t)

Substituting these back into the velocity vector equation:

v = (-2sin(t)) i + (2cos(t)) j

To find the acceleration vector, we can take the time derivative of the velocity vector:

a = (d^2x/dt^2) i + (d^2y/dt^2) j

Taking the derivatives:

d^2x/dt^2 = -2cos(t)

d^2y/dt^2 = -2sin(t)

Substituting these back into the acceleration vector equation:

a = (-2cos(t)) i + (-2sin(t)) j

So the velocity vector is v = (-2sin(t)) i + (2cos(t)) j, and the acceleration vector is a = (-2cos(t)) i + (-2sin(t)) j, both in terms of t.
