Use grouping symbols (parentheses) to make 9 + 3-2 +4 equal 6. Which expression below is true?
O9+(3-2) + 4 = 6
O9+3-(2 + 4) = 6
O (9+3)-2+4=6
O (9+3-2) + 4 = 6
Answer:
the second answer
Step-by-step explanation:
because 19+3 is equal to 12, therefore we substrate by the number we got from 4+2 which is 6, so it will be 12-6 which is equal to 6 ,
A student claims that the next term of the arithmetic sequence 0,2,4, ....... is 8 . Explain and correct the student's error.
an=a1+d(n−1) by applying this formula next term of the arithmetic sequence is 8.
What is arithmetic sequence?See the pattern
2-0 = 2
4-2 = 2
By this we conclude that next term is not 8.
An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence. For instance, the common difference in the arithmetic series 3, 9, 15, 21, and 27 is 6.
Arithmetic sequences are sequences containing these patterns. The distance between succeeding terms in an arithmetic series is always the same. The difference between consecutive words is always two, hence the sequence 3, 5, 7, 9... is arithmetic.
An explicit formula that states a = d (n - 1) + c, where d is the common difference between succeeding words, and c = a1, can be used to establish an arithmetic sequence.

b. Design a simulation and estimate your team's average value per hand.
The team's average value per hand is 0.76 and the simulation is shown in the figure.
Average Value:
Average means the ratio of the sum of all given observations to the total number of observations.
Given,
You are playing a team card game where a team can get 0 points, 1 point, or 3 points for a hand.
The probability of your team getting 1 point for a hand is 60% and of getting 3 points for a hand is 5% .
Here we need to design a simulation and estimate your team's average value per hand.
When we use a random number generator to generate integers
1 through 20, where
1–7 represents 0 points,
8–19 represents 1 point, and
20 represents 3 points.
Do 50 trials and record the results in a frequency table.
The table looks like, the following.
Based on the frequency table, The average value is the sum of the product of each point value and its corresponding frequency is calculated as,
=> average = (0 x 16/50) + (1 x 32/50) + (3 x 2/50)
=> average = 0 + 32/50 + 6/50
=> average = 38/50
Which is approximately equal to,

Determine the slope of the line that contains the given points.
E(5,4), F(8,1)
The slope of the line that contains the given points E(5,4), F(8,1) is -1.
It is given in the question that the line contains the points E(5,4) and F(8,1).
We know that:-
The formula to find the slope of a line that contains points (a,b) and (c,d) is given by:-
m = (d-b)/(c-a)
Here, we have
m = slope of the line
(a,b) = (5,4)
(c,d) = (8,1)
Hence, putting the values of (a,b) and (c,d) , we get

What is meant by centroid theorem?The triangle's centroid is the point where the three medians intersect. According to the centroid theorem, the centroid is 23 times the distance from each vertex to the midpoint of the opposite side.
The centroid has the unique property that the distance from a vertex to the centroid is twice that of the distance from the centroid to the midpoint of the side opposite that vertex for each median. In addition, the three medians of a triangle divide the triangle into six equal-area regions.
Given: In Δ SZU, UJ = 9, VI = 3 , and ZT = 18 .
Since ZV ≅ VU, Y is the midpoint of UZ and SV is a median of Δ ZSU. Similarly, points Y and T are also midpoints of SZ and SU, respectively, so YU and ZT are also medians. Therefore, point J is the centroid of
Δ ZSU and, according to the Centroid Theorem, SJ is 2/3 of SV.
SJ = 2/3 (SV)
= 2/3 (SJ + VJ)
simplifying the above equation, we get

SJ/2 = 3
SJ = 6

Factorize both the denominator and numerator of the rational expression. Remember to write each expression in standard form.
Reduce the expression by cancelling out common factors in the numerator and denominator
Rewrite the remaining factors in the numerator and denominator.
Step-by-step explanation:
Example:
Simplify: (x^{2} + 5x + 4) (x + 5)/(x^{2} – 1)
Solution:
Factoring the numerator and denominator to get;
⟹ (x + 1) (x + 4) (x + 5)/(x + 1) (x – 1)
Now cancel the common terms.
