Answers
Given that:
x = number of adult tickets.
y = number of children's tickets.
And the ordered par (4, 3).
Since an ordered pair is represented by (x, y):
x = 4 = number of adult tickets.
y = 3 = number of children's tickets.
Answer: A. Ms. Monti bought 4 adults tickets and 3 children's tickets.

Keaton needs to fill juice cups for her little sister's birthday party. There are 22 juice cups and each juice cup holds 12 fluid ounces. The juice comes in 1-gallon bottles. How many 1-gallon bottles of juice will Debbie need to purchase?
(1 quart = 32 fluid ounces, 1 gallon = 4 quarts)
Answers
Answer: 3 Gallons
Step-by-step explanation:
To find the total number of ounces she needs of juice we need to multiply the 22 cups by 12 ounces.
22 x 12 = 264
Now to find the number of quarts we need to convert the ounces into quarts by dividing by 32.
264 / 32 = 8.25
To find the number of gallons we need you have to convert it into gallons by dividing by 4.
8.25 / 4 = 2.0625
Because you cannot purchase .0625 of a gallon, we need to round up and purcahse 3.

Solve the systems of equations. List variables a, b, and c.
a-2b+c=8
2a+b-c=0
3a-6b+ 3c = 24
Answers
a = 2b-c+8
b = (-a-c+8)/ 2
c = -a+2b+8
variable a ,b & c for 2a+b-c=0
a = (-b+c) / 2
b=-2a+c
c = 2a+b
variable a ,b & c for 3a-6b+ 3c = 24
a=2b-c+8
b = - (-a-c+8)/ 2
C = -a+2b+8
How to find variables a,b,c ?
1) Finding variable a ,b & c for a-2b+c=8
Finding a=(a-2b+c) + (2b-c)=8+ (2b-c)
a -2b+c+2b-c=8+2b-c
a-2b+2b+c-c=2b-c+8
a = 2b-c+8
Finding b =a-2b+c=8
(a-2b+c) + (−a − c) = 8+ (-a-c)
a-2b+c-a-c=8-a-c
b = (-a-c+8)/ 2
Finding c =a-2b+c8
(a-2b+c)+(-a+2b)=8+(-a+2b)
c = -a+2b+8
2) Finding variable a ,b & c for 2a+b-c=0
Finding a=2a+b-c=0
(2a+b-c)+(-b+c) = -b+c
2a+b-c-b+c = -b+c
a = (-b+c) / 2
Finding b =2a+b-c=0
(2a + b-c) + (-2a + c) = -2a + c
b=-2a+c
Finding c =2a+b-c=0
(2a+b-c) + (-2a - b) = -2a-b
c = 2a+b
3) Finding variable a ,b & c for 3a-6b+ 3c = 24
Finding a=3a-6b+3c = 24
(3a-6b+3c) + (6b-3c) = 24 + (6b- 3c)
3a-6b+3c+6b-3c = 24 + 6b-3c
a=2b-c+8
Finding b =3a-6b+3c=24
(3a-6b+3c) + (−3a - 3c) = 24 + (-3a - 3c)
3a-6b+3c-3a-3c-24-3a-3c
3a-6b+3c=24
(3a-6b+3c) + (−3a - 3c) = 24 + (-3a - 3c)
b = - (-a-c+8)/ 2
Finding c =3a-6b+3c=24
(3a-6b+3c) + (-3a+6b)=24+ (-3a+6b)
3a-6b+3c-3a+6b-24-3a+6b
C = -a+2b+8
System of equations :In mathematics, a set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.A system of equations is a set of one or more equations involving a number of variables.The solutions to systems of equations are the variable mappings such that all component equations are satisfied—in other words, the locations at which all of these equations intersect. A system of equations can be classified in a similar manner as single equations.The following set of equations is an example of system of equations,2x - y = 12
x - 2y = 48
Solving a system of equations means finding the values of the variables used in the set of equations.We compute the values of the unknown variables still balancing the equations on both sides.The main reason behind solving an equation system is to find the value of the variable that satisfies the condition of all the given equations true.To learn more about System of equations refer :

Explanation:
According to the concept of mutually exclusive:
Tw events A and B of any sample space are mutually exclusive if the occurrence of any one of them excludes the occurrence of the other event.
Then, twp events A and B cannot occur simultaneously.
Now,
From the given question:
Event A and events B, which means, rational numbers and irrational numbers are mutually exclusive because they have no numbers in common.
So, they span the entire set of real numbers which means both are real numbers.
Final answer:

Answers
You have to calculate the z-value or value of the test statistic z, for the proportion of yellow pods. The form of the z-statistic used to study the population proportion is:
[tex]Z=\frac{\hat{p}-p}{\sqrt[]{\frac{p(1-p)}{n}}}\approx N(0,1)[/tex]The population proportion of the yellow pods is p=0.25.
From a sample of 430 peas, 126 of them had yellow pods, using this information you have to calculate the sample proportion p-hat (^p)
The sample proportion is equal to the quotient between the number of successful outcomes "x" (number of yellow pods) and the total number of outcomes "n" (number of peas sampled)
[tex]\begin{gathered} \hat{p}=\frac{x}{n} \\ \hat{p}=\frac{126}{430} \\ \hat{p}=0.29 \end{gathered}[/tex]Once determined the sample proportion, you can calculate the z-value as follows:
[tex]\begin{gathered} Z=\frac{0.29-0.25}{\sqrt[]{\frac{0.25(1-0.25)}{430}}} \\ Z=\frac{0.04}{\sqrt[]{\frac{0.25\cdot0.75}{430}}} \\ Z=\frac{0.04}{\sqrt[]{\frac{0.1875}{430}}} \\ Z=1.915\approx1.92 \end{gathered}[/tex]The value of the test statistic is 1.92.
*-*-*-*-*
The standard deviation of the distribution of the sample proportion:
To simplify the calculations you can calculate the standard deviation separately, the formula for this measure is the denominator of the formula of the Z-statistic:
[tex]\sigma=\sqrt[]{\frac{p(1-p)}{n}}[/tex]Using p=0.25
[tex]\begin{gathered} \sigma=\sqrt[]{\frac{0.25(1-0.27)}{430}} \\ \sigma=\sqrt[]{\frac{0.25\cdot0.75}{430}} \\ \sigma=\sqrt[]{\frac{0.1875}{430}} \\ \sigma=\sqrt[]{\frac{3}{6880}} \\ \sigma=0.0208 \end{gathered}[/tex]Then you can replace the result in the denominator of the formula to determine the Z-value:
[tex]\begin{gathered} Z=\frac{\hat{p}-p}{\sqrt[]{\frac{p(1-p)}{n}}} \\ Z=\frac{0.29-0.25}{0.0208} \\ Z=\frac{0.04}{0.0208}\approx1.92 \end{gathered}[/tex]Final and of the non side round your answer to the nearest 10th 18 and 4

In the right triangle, there is a relation between its sides
(hypotenuse)^2 = (leg1)^2 + (leg2)^2
The hypotenuse is the side opposite to the right angle
leg1 and leg 2 are the sides of the right angle
In the given figure
The hypotenuse = 18
leg1 = 4
(18)^2 = (4)^2 + (leg2)^2
324 = 16 + (leg2)^2
Subtract 16 from both sides
324 - 16 = 16 - 16 + (leg2)^2
308 = (leg2)^2
Take square root for both sides

write an equation parallel to y=3x+6 that passes through the point (4,7).
Answers
The equation of a line in the slope intercept form is expressed as
y = mx + c
Where
m represents slope
c represents y intercept
The given equation is
y = 3x + 6
If we compare the given equation with the slope intercept equation, we can see that slope = 3
If two lines are parallel, it means that they ahve the same slope. Thus, the slope of the line
that passes through the point (4,7) is 3
We would find it's y intercept, c by substituting m = 3, x = 4 and y = 7 into the slope intercept equation. It becomes
7 = 3 * 4 + c
7 = 12 + c
c = 7 - 12
c = - 5
Thus, we would substitute m = 3 and c = - 5 into the slope intercept equation to get the equation of the line. Thus, we have
y = 3x - 5

Answers
The percentage of students who got above 90 point is 80%
the decimal student got grade above the 90 points is 0.8
What is Decimal?
The accepted method for representing both integer and non-integer numbers is the decimal numeral system. It is the expansion of the Hindu-Arabic numeral system to non-integer values. Decimal notation is the name for the method of representing numbers in the decimal system.
Given,
Total no. of students = 30
No. of students who score above 90 points = 24
We have to find the percentage of the students who got above 90 points
So, to calculate,
24 / 30 x 100 = 80%
Now, we have to convert percent into decimal
so, we have,
80 / 100 = 0.8
