Three data sets show the number of text messages sent by Jada, Diego, and Lin over the past 6 days as well as the mean number of text messages sent by each student per day.
Answers
Answer:
Jada: 1
Diego: 4/3
Lin: 10/3
Step-by-step explanation:
To find MAD, you calculate the mean of the data sets (which you were given in this case), and then find the distance of each number in the data set from the mean. You then write all the distances down, and then find the mean of THAT. Now you have your MAD.
Example (Jada)
Data set: 4,4,4,6,6,6
Mean: 5
Distances: 1,1,1,1,1,1
Mean of distances (and therefore the MAD):
(1+1+1+1+1+1) divided by 6 = 1

Maria claims that any fraction located between 1/5 and 1/7 on a number line must have a denominator of 6.
Enter a fraction that shows Maria's claim is incorrect.
Answers
Step-by-step explanation:
I want to know about exponent and surds
Explanation:
Let's rewrite each given fraction with a common denominator of 5*7 = 35.
1/5 = (1/5)*(7/7) = 7/35
1/7 = (1/7)*(5/5) = 5/35
Then we can see that 6/35 is between 5/35 and 7/35, since 6 is between 5 and 7.
Put another way: 5/35 < 6/35 < 7/35 since 5 < 6 < 7
This then means 1/7 < 6/35 < 1/5
Therefore, Maria's claim is incorrect.

Try to solve the equation below.
2x^2+18=10
Explain why this equation has no real number solutions.
Answers
Answer:
Step-by-step explanation:
The discriminant of this equation, i.e, D=\(b^{2}-4ac\) is less than 0:
D= 0-(4*2*18) --> which is clearly negative
When D is less than 0, the equation has no real number solutions.
Therefore, \(2x^{2}+18=0\) has no real roots

Q: Which statement is correct for the graph of the specified function?
A: The maximum value of the quadratic function occurs at y = 4.
Step-by-step explanation: The minimum value of the quadratic function occurs at x = 0 is false because this quadratic does not have a minimum value. It has a maximum value when y=4. The true statement is that the x-values of the linear function increase (go up) as the y-values decrease (go down). Also i took the test

Y=1
(X,y)=(4,-1)
-6x4-10x (-1)=-14
4x4+10x(-1)=6
-14=-14
6=6
(X,y)=(4,-1)
Step by Step:
-6x -10y = -14
+4x +10y = 6
(The 10ms are already the same so we’re going to cancel those out. In front of the first 10 there is a subtraction sign, and I front of the second one there is an addition sign. Since the signs are different this means we’re going to add.)

(Now that we found x we’re going to substitute it in one of the equations and search for y)

1/5m = 20
C. 45 = 3(x + 1)
D. 22.5 = 1.5x
E. Mark has $20 in his bank account. He saves $5 each week. How much money does Mark have in his account after 9 weeks? Use w to represent the number of weeks and t to represent the total amount Mark has after any number of weeks.
1) One-step equation:
5x + 3 = 18
Solution:
Subtract 3 from both sides to isolate the variable:
5x + 3 - 3 = 18 - 3
5x = 15
Divide both sides by 5 to solve for x:
5x/5 = 15/5
x = 3
2) One-step equation:
4y - 7 = 9
Solution:
Add 7 to both sides to isolate the variable:
4y - 7 + 7 = 9 + 7
4y = 16
Divide both sides by 4 to solve for y:
4y/4 = 16/4
y = 4
3) Equation with fractions:
2/3 x + 1/4 = 1/2
Solution:
Subtract 1/4 from both sides to isolate the variable:
2/3 x + 1/4 - 1/4 = 1/2 - 1/4
2/3 x = 1/4
Multiply both sides by 3/2 to solve for x:
(2/3 x) * (3/2) = (1/4) * (3/2)
x = 3/8
4) Equation with fractions:
3/4 z - 1/2 = 1/8
Solution:
Add 1/2 to both sides to isolate the variable:
3/4 z - 1/2 + 1/2 = 1/8 + 1/2
3/4 z = 5/8
Multiply both sides by 4/3 to solve for z:
(3/4 z) * (4/3) = (5/8) * (4/3)
z = 5/6
5) Equation with distributive property:
2(x + 5) = 16
Solution:
Use the distributive property to simplify the left side of the equation:
2(x + 5) = 2x + 10
Subtract 10 from both sides to isolate the variable:
2x + 10 - 10 = 16 - 10
2x = 6
Divide both sides by 2 to solve for x:
2x/2 = 6/2
x = 3
6) Equation with decimals:
0.5x + 1.25 = 2.75
Solution:
Subtract 1.25 from both sides to isolate the variable:
0.5x + 1.25 - 1.25 = 2.75 - 1.25
0.5x = 1.5
Divide both sides by 0.5 to solve for x:
0.5x/0.5 = 1.5/0.5
x = 3
7) Real-world problem:

Explain the cosine rule and sine rule while also saying how to use it and provide examples (keep it in simple terms)
Answers
Answer:
Sure, I'll explain the cosine rule and sine rule in simple terms:
The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.
Here's an example of how to use the cosine
Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.
Using the cosine rule:
a^2 = b^2 + c^2 - 2bc * cosA
where A is the angle opposite side a, we can plug in our values and solve for a:
a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)
a^2 = 64 + 36 - 96 * 0.707
a^2 = 10.56
a = sqrt(10.56)
a = 3.25 (rounded to two decimal places)
Therefore, the length of side a is approximately 3.25 units.

Combine like terms
a^2 +3b = a^2 +4b
-a^2 + 3b -2a^2 = 3a^2 + 3b
Combine like terms
-3a^2 +3b = 3a^2 +3b
a^2 + 3b - 2a^2 = 3a^2 +4b -4a^2

Four more than half of the students in Bryan’s homeroom have tickets to attend the school’s musical. 20 students from that class have tickets. Select all the equations that can be used to find the number of students, m, in Bryan’s homeroom.
CHECK IMAGE!!
Answers
The options b and d are suitable equations. The equations are \(\frac{1}{2} m+4=20 and 4=20-\frac{1}{2}m\). The number of students in Bryan's homeroom in this equation is m.
The following information is given in the question: The number of students who possess tickets = 20. And, m is the number of students in Bryan's homeroom. let us solve the sum using this particular equation \(\frac{1}{2} m+4=20\) to figure out how many students are in Bryan's homeroom.
On solving the given equation,
\(\frac{1}{2} m+4=20 \\4+\frac{2}{m} = 20\\8+m=40\\m= 40-8 = 32. \\\)
As a result, there are 32 students in Bryan's homeroom(m). The options that are used to find the number of students, m, in Bryan’s homeroom are \(\frac{1}{2} m+4=20\) and \(4=20-\frac{1}{2}m\). All other options do not satisfy the conditions given in the question.
