Column totals 0.42 0.31 0.27 1
C. Method of Travel to School
Walk/Bike Bus Car Row totals
Below age 15 0.52 0.36 0.11 1
Age 15 and above 0.33 0.26 0.41 1
Column totals 0.42 0.31 0.27 1
D. Method of Travel to School
Walk/Bike Bus Car Row totals
Below age 15 0.57 0.55 0.18 0.46
Age 15 and above 0.43 0.45 0.82 0.54
Column totals 1 1 1 1
The answer is option B as you can see this two way frequency table has the same data as in the question.
Hope this helps!
Answer:
The table representing the number of students by which mode of transport they travel is given as:
Walk or bike Bus Car Row Total
Below age 15 87 60 18 165
Age 15 and above 65 50 80 195
Column Total 152 110 98 360
We know that a relative frequency of an event is the ratio of frequency to the total number of trials.
i..e we divide each frequencies by 360 to obtain a two-way relative frequency.
Hence,the table is given as:
Walk or bike Bus Car Row Total
Below age 15 0.24 0.17 0.05 0.46
Age 15 and above 0.18 0.14 0.22 0.54
Column Total 0.42 0.31 0.27 1

The required simplified value of the t in the given proportion is given as t = 48.
What is simplification?
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Given the expression of proportion,
t/16 = 40 / 50
t / 60 = 4 / 5
Multiply both sides by 60,
t / 60 × 60 = 4 / 5 × 60
t = 4 × 12
t = 48
Thus, the required simplified value of the t in the given proportion is given as t = 48.

Explanation:
Algebraically, an odd function is one where f(-x) = -f(x). This means that if we substitute -x for every x in the function, it should be the same as switching every sign in the function. This does not always work.
For example, if f(x)=x³+7:
f(-x)=(-x)³+7=-x³+7.
However, since the 7 did not become -7, it is not the same as -f(x), so it is not an odd function.
Dimetri statement is incorrect, as the function is odd if its greatest degree is odd when the lower terms are ignored.
What is a function?
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
As we know,
For even function: f(-x) = f(x)
For odd function: f(-x) = -f(x)
If Dimetri says that, a function that is made of terms where the variable is raised only to an odd power will be an odd function.
The Dimetri statement is incorrect, as the function is odd if its greatest degree is odd when the lower terms are ignored.
Thus, Dimetri statement is incorrect, as the function is odd if its greatest degree is odd when the lower terms are ignored.

AABC - ADEF.
Based on the dimensions in the diagram, what is the
perimeter of AABC?
A-9 in.
B-10 in.
C-9.5 in.
D-10.5 in.
Answers
Answer:
Perimeter of ΔABC is 9.5 in.
Step-by-step explanation:
Given:
ΔABC ΔDEF
DE = 6 in.
EF = 5.25 in.
DF = 3 in.
AB = 4 in.
We need to find the Perimeter of ΔABC.
Solution:
First we will find the sides of ΔABC.
Now By Triangle similarity property which states that:
"When two triangles are similar the the ratio of their corresponding sides are equal."
From Above property we can say that;
Now we will find BC and AC
Also;
Now In ΔABC
AB = 4 in
BC = 3.5 in
AC =2 in.
Now Perimeter of ΔABC can be calculated as sum of all sides.
Perimeter of ΔABC = AB +BC +AC = 4 + 3.5 + 2 = 9.5 in
Hence Perimeter of ΔABC is 9.5 in.
