What is a two-way frequency table?A two-way or contingency table is a statistical table that shows the observed number or frequency for two variables, the rows indicating one category and the columns indicating the other category.
Given, Mr. Cho made a two-way table to describe members of his family.
Items in the row are aligned from left to right, even as columns are aligned from pinnacle to bottom. A row is a horizontal alignment of information, even as a column is vertical. Data in a row carries records that describe an unmarried entity, even as information in a column describes a subject of records all entities possess.
Since Mr. Cho wants to describe his family in a proper way
Thus, he needs to Represent in such a form that every quality can be expressed evenly.
Therefore, whether the relative was born in Korea; or whether the relative speaks Korean could describe the row and column headings for Mr. Cho’s table.

Solve the following system:
y = x + 3
3x + y = 19
O (7,4)
O(-4,7)
O (4,7)
O (4.-7)
Answer:
(4, 7) (third answer choice)
Step-by-step explanation:
In the system
y = x + 3
3x + y = 19
the first equation already gives y in terms of x. Thus we can substitute x + 3 for y in the second equation:
3x + (x + 3) = 19, which simplifies to:
4x = 16, yielding x = 4. Substituting 4 for x in the first equation, we get:
y = (4) + 3 = 7.
Thus, the solution is (4, 7) (third answer choice).
How do you Convert the decimal into a mixed number 10.5
Answer:
it would be 10 1/2
Step-by-step explanation:
The ten is already a whole number so it would be itself. .5 is in the tenths place so it would be put over ten (5/10). Simplify 5/10 to 1/2 because 5 is half of 10

What is the height of this isosceles triangle?
Answer:
height ≈ 11.9 units
Step-by-step explanation:
Construct a perpendicular bisector from the vertex to the base, thus splitting the triangle into 2 right triangles.
Using the sine ratio in one of these right triangles, then
sin48° = [tex]\frac{opposite}{hypotenuse}[/tex] ( the opposite is the height h )
sin48° = [tex]\frac{h}{16}[/tex] ( multiply both sides by 16 )
16 × sin48° = h , thus
h ≈ 11.9 ( to the nearest tenth )

Answer: C
Step-by-step explanation:
Since you are multiplying the two scientific notations, you would multiply 8.1 and 2.2. After, you would multiply the 10³ and 10^6. When you multiply 2 exponents with the same base, you add the exponents. Therefore, C is your correct answer.
Answer:
(8.1*2.2)*10^3+6
Step-by-step explanation:
The equation = 1.782*10^10=17820000000
The top equation = 10.3*1001000
The second equation = 17.82*10^18=17820000000000000000
The third equation = 17.82* 1000000000= 17820000000

Isabella buys a 1.75 litre carton of apple juice. What is the largest number of 200 millilitre glasses that she can have from the carton?
Isabella can have 8 full glasses and 0.75(3/4) glasses from the 1.75-liter carton of apple juice.
What is a fraction?Fraction number consists of two parts one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
Isabella buys a 1.75-liter carton of apple juice.
To convert it to milliliter multiply it by 1000
1.75 liter in ml = 1.75×1000 = 1750 ml
Let's suppose the number of glasses she can have is x, so the value of x:
x = 1750/200 = 8.75 glasses.
Thus, Isabella can have 8 full glasses and 0.75(3/4) glasses from the 1.75-liter carton of apple juice.

Events A and B are overlapping.
P(A) = 4/11; P(B) = 3/11, P(A and B) =2/11 .
Find P(A or B).
Answer:
5/11
Step-by-step explanation:
Since the events are overlapping...
P(A or B) = P(A) + P(B) - P(A and B)
P(A) = 4/11
P(B) = 3/11
P(A and B) = 2/11
P(A or B) = 4/11 + 3/11 - 2/11
P(A or B) = 5/11

PLZ HELP ASAP WILL GIVE BRAINLIEST- If the perimeter of the triangle is 91 inches, what is the length of the base? -Picture Below!
Answer:
Base = 35 inch
Step-by-step explanation:
Given that the triangle is an isosceles triangle;
The length of the two sides is: 12b - 8
The length of the base is: 9b + 8
Perimeter = 91 inches
Required
Calculate the length of the base;
The perimeter of a triangle is gotten by adding the length of the three sides.
So, in this case; we have
[tex]Perimeter = 12b - 8 + 12b - 8 + 9b + 8[/tex]
Collect like terms
[tex]Perimeter = 12b + 12b + 9b - 8 - 8 + 8[/tex]
[tex]Perimeter = 33b - 8[/tex]
Substitute 91 for Perimeter
[tex]91 = 33b - 8[/tex]
Add 8 to both sides
[tex]91 + 8 = 33b - 8 + 8[/tex]
[tex]99 = 33b[/tex]
Divide both sides by 33
[tex]\frac{99}{33} = \frac{33b}{33}[/tex]
[tex]3 = b[/tex]
[tex]b = 3[/tex]
Recall that the base of the triangle is 9b + 8
Base = 9b + 8
Substitute 3 for b
Base = 9(3) + 8
Base = 27 + 8
Base = 35 inch

The sum of the interior angles of a regular polygon is 1800 degrees. How many sides does is have? *
1 point
9 sides
10 sides
11 sides
12 sides
Answer:
12 sides
Step-by-step explanation:
To find the number of sides of a regular polygon with the sum of interior angles of 1800 degrees, we will follow the steps below;
first write down the formula for finding sum of the interior angle of a polygon
s= (n-2)180
where s is the sum of the interior angle and n is the number of side
from the question given, sum of the interior angle s=1800 degrees
substitute s=1800 degree into the formula and solve for n
s= (n-2)180
1800 = (n-2)180
divide both-side of the equation by 180
1800/180 = n-2
10 = n - 2
add 2 to both-side of the equation
10 + 2 = n
12 = n
n= 12
The polygon have 12 sides

There are 68 apples in the school kitchen. The school needs 130 apples for all the students in grade 2. The school gets two boxes of apples. Each box has three dozen apples inside. Does the school have enough apples for all the students in grade 2 ?
Answer:
Yes.
Step-by-step explanation:
Apples needed =130
apples in the kitchen =68
130-68= 62 to complete for all the students
1 (3 dozens x 12) = 36 apples x 2= 72
68 +72=140 apples available for all the students
Answer:
Yes
Step-by-step explanation:
The reason for this is because 1 dozen is 12. And the schools bought 6 dozens of apples. If you multiply 36 by 2 you get 72. Then if you add 72+68 you get 140 apples, but the school only needed 130 apples. So yes the school has enough apples for grade 2.
