ABCD is a quadrilateral
Work out the length of CD
Give your answwer in 3 significant figures
Answers
The length of CD is 20.48 cm
In this question, we have been given a quadrilateral ABCD.
We need to find the length of CD.
From given figure, consider right triangle ABD
We find the value of sine of angle ADB
sin(∠ADB) = AB/DB
sin(38°) = 10 / DB
0.61587 = 10/DB
DB = 10/0.6157
DB = 16.24 cm
Applying sine rule to triangle BCD,
sin(B)/CD = sin(C)/DB
sin(105°) / CD = sin(50°) / 16.24
0.9659 / CD = 0.766 / 16.24
CD = (0.9659 * 16.24) / 0.766
CD = 20.48 cm
Therefore, the length of CD is 20.48 cm

which best describes the solutions for this system? y=3x-4 2y=2x+1infinitely many solution not a solution there one solution??
Answers
The equations are y = 3x - 4 and 2y = 2x +1.
If the graph of equation intersect each other at one point then there is one solution, if line lies on one another then there are infinitely many solution and if lines are parallel to each other then there is no solution.
Plot the equation on the graph.
From the graph, it can be observed the lines intersect each other at one point only lies in first quadrant, so there is one solution located in the first quadrant.

Answers
This problem is about deductive reasoning.
The given statements are
• If you are on the basketball team, then you have practice on Thursday.
,• You have practice on Thursday.
You can see these problems as consequences from a specific event. For example, the first statement is saying that "if" you are on the team, then you have practice on Thursday, this means that if you are not on the team, then you don't have practice on Thursday.
So, in the second statement is actually saying that you will have practice on Thursday, the question would be What does this mean?
Well, according to the first statement, if you have practice on Thursday that means you are on the basketball team.

Answers
The given polynimial exression is
(w^3-2w^2-2w+1)÷(w-1)
We wuld apply the long division method as shown below
The first step is todivide w^3 by w to give us w^2. w^2 is used to multiply w + 1 to give us w^3 + w^2 and this is subtracted from w^3 - 2w^2. The process continues until we cannot divide further. Thus, from the daigram above, the solution is
w^2 - 3w + 1

Mrs. Gomes found that 40% of students at her high school take chemistry. She randomly surveys 12 students. What is the probability that at most 4 students have taken chemistry? Round the answer to the nearest thousandth.READ ANSWERS!0.0080.4380.5620.665
Answers
If we don't allow to repeat a pick on the sample, than each student we pick will change the probability of picking the next one and, since we don't know the total number of students at her high school, we wouldn't be able to calculate this probability.
Thus, to calculate this with the provided information, we need to assume that we can repeat a student in the sample, that way the probability of picking a chemistry student will always be 40%.
So, with that assumption, we can use binomial probability to calculate the probability of picking at most from from that have taken chemistry on the 12 picked students.
Since we want at most 4, we have the consider the term of the binomial for which 0 students from chemistry were picked, the term for 1 from chesmitry, the term for 2, the term for 3 and the term for 4.
Let p be the probability of picking 1 student from chemistry, n be the total number of students picked and k be the number of students on those that are from chemistry. Then, each term will have the following:
[tex]B(k)=\frac{n!}{k!(n-k)!}p^k(1-p)^{n-k}_{}[/tex]In this case, n is always 12 and p is always 0.4, so 1 - p is always 0.6.
k will vary from 0 to 4 and the total probability will be the sum of each term.
The term for 0 students from chemistry has k = 0, so:
[tex]B(0)=\frac{12!}{0!(12-0)!}(0.4)^0(0.6)^{12-0}=1\cdot1\cdot(0.6)^{12}=0.0021767\ldots[/tex]The term for 1 student from chemistry has k = 1, so:
[tex]B(1)=\frac{12!}{1!(12-1)!}(0.4)^1(0.6)^{12-1}=12\cdot0.4\cdot(0.6)^{11}=0.0174142\ldots[/tex]The term for 2 student from chemistry has k = 2, so:
[tex]B(2)=\frac{12!}{2!(12-2)!}(0.4)^2(0.6)^{12-2}=\frac{12\cdot11}{2}\cdot(0.4)^2\cdot(0.6)^{10}=0.0638522\ldots[/tex]The term for 3 student from chemistry has k = 3, so:
[tex]B(3)=\frac{12!}{3!(12-3)!}(0.4)^3(0.6)^{12-3}=\frac{12\cdot11\cdot10}{3\cdot2}\cdot(0.4)^3\cdot(0.6)^9=0.1418939\ldots[/tex]The term for 4 student from chemistry has k = 4, so:
[tex]B(4)=\frac{12!}{4!(12-4)!}(0.4)^4(0.6)^{12-4}=\frac{12\cdot11\cdot10\cdot9}{4\cdot3\cdot2}\cdot(0.4)^4\cdot(0.6)^8=0.2128409\ldots[/tex]So, the total probability will be the sum of all these term:
[tex]\begin{gathered} P=B(0)+B(1)+B(2)+B(3)+B(4) \\ P=0.0021767\ldots+0.0174142\ldots+0.0638522\ldots+0.1418939\ldots+0.2128409\ldots \\ P=0.4381782\ldots\approx0.438 \end{gathered}[/tex]So, the probability is approximately 0.438.

o MIDSEGMENT THEOREM 12)Triangle ABC has vertices A(-5,2), B(1,5) and C(1,-1). Determine the point of intersection of the medians, and state its coordinate
Answers
To determine the point of intersection of the medians and its cordinate:
Let O(x, y) be the centroid of the triangle.
The median of a triangle is a line segment that joins the vertex of a triangle to the midpoint of the opposite side. There are three medians in a triangle; and the medians of a triangle intersect at a point called the centroid.
The centroid of a triangle is gotten from the average of the x coordinates and the y coordinates of all the three vertices.
For Triangle ABC has vertices A (-5,2) B (1,5) C (1,-1) and centroid O(x, y).
Hence:
[tex]x=\frac{-5+1+1}{3}=-\frac{3}{3}=-1[/tex][tex]y=\frac{2+5+(-1)}{3}=\frac{7-1}{3}=\frac{6}{3}=2^{}[/tex]The centroid is at (-1, 2)
Hence the point of intersection and coordinate = (-1 , 2)
Describe the end behavior f(x)=x^3-4x^2+7
Answers
The behavior of the function falls to the left and rises to the right.
Given function f(x)=x^3-4x^2+7,
Firstly identify the degree of the function which is :
3
Now identify the leading coefficient which is :
1
Now, we know that if the degree is odd then the function ends in opposite direction.
And also the leading coefficient is positive which leads to rise of the graph to the right.
By using the degree and leading coefficient we can determine the behavior of the function by using below statements ;
1. Even and Positive: Rises to the left and rises to the right.
2. Even and Negative: Falls to the left and falls to the right.
3. Odd and Positive: Falls to the left and rises to the right.
4. Odd and Negative: Rises to the left and falls to the right
So the behavior of the function falls to the left and rises to the right.
