When Eric multiplied two binomials together, his result was a trinomial. An example is
(+2) G + 3) = x2 + 5x+6. Eric concluded that the product of any two binomials is a
trinomial. The product of which pair of binomials disproves Eric's conclusion?
Answer:
(x + 4)(x - 4)
Step-by-step explanation:
There are actually quite a lot of pairs of binomials the disproves Eric's conclusion, but they all model after the same special product: a^2 - b^2.
The special product a^2 - b^2 can be factored into (a + b)(a - b) and for all real a and b, it will come out as a binomial.
Here is an example:
(x + 4)(x - 4)
We can use the distributive property to get:
x^2 - 4x + 4x - 16
which is the same as
x^2 - 16
This would disprove Eric's conclusion.
Two Step Equations

solve for w
Answer:
w = 12ds/x
Step-by-step explanation:
Here, we want to write the equation in terms of w
What we simply do here is to bring x and w to reach others side
we have this as;
w = 12ds/x

According to the word problem:
A number cube is numbered 1-6A spinner has 3 consonants and 1 vowel-------------------------------------------------------------------
-------------------------------------------------------------------
The question is asking the probability of rolling a number less than 3 and a consonant.
Well, there are 2 numbers less than 3 on the number cube, 2 and 1. So of the six numbers, 2 of them are less than 3 (2/6).
There are 3 consonants on the spinner. So, of the 4 letters, 3 of them are constants (3/4).
Now, that we know the likelihood of each event, multiply them.
[tex]2/6*3/4=6/24[/tex]
[tex]6/24=1/4(simplified)[/tex]
Use a calculator to find the value of these data. Round the value to three
decimal places.
A-0.953
B. -1.909
C. 0.909
D. 0.953
The value of coefficient of correlation coefficient is -0.953 which is a negative correlation between x and y option (A) is correct.
What is correlation?It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
We have given data in the table.
As we know, the formula for the correlation is given by:
[tex]\rm r = \dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{{[n\sum x^2- (\sum x)^2]}}\sqrt{[n\sum y^2- (\sum y)^2]}}[/tex]
After plugging the value, we will get the value of r:
r = -0.953
Thus, the value of coefficient of correlation coefficient is -0.953 which is a negative correlation between x and y option (A) is correct.

Answer:
1: one solution *x=6
2: no solution
Step-by-step explanation:
1: 4/ 2x -6 = 10/ x +9 --> *cross multiply*
20x - 60 = 4x + 36 --> *subtract 4x from both sides*
16x - 60 = 36 --> *add 60 to both sides*
16x = 90 --> divide by 16
x = 6

there are 30 students in a class. of those, 15 take history, 18 take geography, and 5 take neither of
these subjects. how many students
take both subjects?
.
Answer:
n(U)=30
n(H)=15
n(G)=18
n(H ∪ G)'=5
n(H ∪ G)=n(U)-n(H ∪ G)'
=30-5=25
So ,n(H ∩ G)=n(H)+n(G)-n(H ∪ G)
=15+18-25=8
Therefore, 8 students take both subjects.
A set is a mathematical model for a collection of diverse things. The total number of students who who take both History and Geography is 8.
What is a set?A set is a mathematical model for a collection of diverse things; it comprises elements or members, which can be any mathematical object: numbers, symbols, points in space, lines, other geometrical structures, variables, or even other sets.
Given that there are 30 students in a class. of those, 15 take history, 18 take geography, and 5 take neither of these subjects. Therefore, we can write the following values,
Total students, n(S)=30Students who take History, n(H)=15Students who take Geography, n(G)=18Students who take neither of the subject, n(H' ∪ G') =5Now, the number of students who take at least one of the two subject can be written as,
Students who choose at least one subject
= Total students - Students who take neither of the subject
n(H ∪ G) = n(U) - n(H ∪ G)'
n(H ∪ G) = 30 - 5
=25
Further, the total number of students who who take both the subjects can be written as,
Students who take both the subjects = Students who take History + Students who take Geography - Students who choose at least one subject
n(H ∩ G) = n(H) + n(G) - n(H ∪ G)
n(H ∩ G) = 15 + 18 - 25
n(H ∩ G) = 8
Hence, the total number of students who who take both History and Geography is 8.

What is the equation of the circle with: center (5, 7) & point on the circle: (-2, 8)?
Answer: (x - 5)^2 + (y - 7)^2 = 50
Step-by-step explanation:
The general equation for a circle is (x - a)^2 + (y - b)^2 = r^2 where (a, b) is the centre
Use Pythagoras to find r^2
r^2 = (5 - -2)^2 + (7 - 8)^2
= 7^2 + (-1)^2
= 50
So the circle is (x - 5)^2 + (y - 7)^2 = 50

Kailynn has a bag with an equal number of red, yellow, and blue marbles. She
makes a tree diagram to show the sample space if she randomly selects two
marbles out of the bag.
What is the probability that both marbles selected are different colors?
Answer:
6/9
Step-by-step explanation:
Probability is the likelihood or occurrence of an event. Probability is the ratio of the total number of possible outcomes to the total outcomes. That is:
Probability = total possible outcomes / total outcomes
From the tree diagram we can see that:
total outcomes = {RR, RY, RB, YR, YY, YB, BR, BY, BB} = 9
getting different colors = {RY, RB, YR, YB, BR, BY} = 6
Therefore, the probability that both marbles selected are different colors = number of different colors / total outcomes
The probability that both marbles selected are different colors = 6 / 9

Step-by-step explanation:

Measures of∠QTR, ∠RQS, m arcTS and m arcQT are 55°, 47°, 102° and 54° respectively.
What is angle?An angle is formed when two straight lines intersect at a point. The amount of "spread" between these two rays is called the "angle". It is represented by the symbol ∠. Angles are usually measured in degrees and radians. This is a measure of roundness or rotation.
Given,
In circle P,
m arcQR = 110°
m arcRS = 94°
∠QRT = 27°
Measure of arc is twice to the angle made by arc on boundary of the circle.
m arcQR = 2∠QTR
110° = 2∠QTR
∠QTR = 110/2
∠QTR = 55°
m arcRS = 2∠RQS
94° = 2∠RQS
∠RQS = 94°/2
∠RQS = 46°
m arcQT = 2∠QRT
m arcQT = 2(27°)
m arcQT = 54°
sum of all arcs made on a circle is 360°
m arcQT + m arcTS + m arcRS + m arcQR = 360°
54° + 94° + 110° + m arcTS = 360°
m arcTS = 360° - 258°
m arcTS = 102°
Hence, 55°, 47°, 102° and 54° are measures of∠QTR, ∠RQS, m arcTS and m arcQT respectively.
