A number is divisible by 3 if the sum of the digits of the number is divisible by 3.This statement is a conditional statement. However, it is not in its standard form. A conditional statement is known as an If-then statement.
It should be written as:
If the sum of the digits of the number is divisible by 3 then a number is divisible by 3.
There are two parts of a conditional statement. The first part is the hypothesis, the second part is the conclusion. The hypothesis starts with "if". The conclusion starts with "then".
The conclusion of the conditional statement is THEN A NUMBER IS DIVISIBLE BY 3.
Answer:
8xy-3y + 2(9x-5y+4) = 18
Step-by-step explanation:
We need to find the value of the given expression:
8xy-3y + 2(9x-5y+4) ....(1)
when x = 3 and y = -4
Put the values of a and y in equation (1)
8×3×(-4)-3(-4)+ 2(9×3-5(-4)+4)
= -96 +12 + 2(27 + 20 +4)
= -84 + 2(51)
= -84 + 102
= 18
Hence, the value of the given expression is 18.
<u>Multiple Regression Analysis is the technique used o see if there is any impact of price point, color, or the interaction</u>
<u />
Step-by-step explanation:
- Multiple regression is a statistical technique which is used to predict the value of a variable based on the values of the two or more variables.
- In the above example we want to predict the Purchase value depending upon the value of the price points and the value of the product colors.
Answer:
- all right angles are congruent.
- opposite sides of a parallelogram are congruent
- SAS congruence postulate
- corresponding parts of congruent triangles are congruent
Step-by-step explanation:
Given : Parallelogram JKLM is a rectangle and by the definition of rectangle, 
are right angles,
Since all interior angles of rectangle are right angle.
then 
, because all right angles are congruent.
Also, opposite sides of a parallelogram are congruent.
and 
by the reflexive property of congruence.
Now, by the SAS congruence postulate,
,
Since corresponding parts of congruent triangles are congruent, ∴
- The SAS postulate says that if two sides and the included angle of a triangle are congruent to two sides and the included angle of another triangle then the two triangles are congruent.
Answer: Population = Total students attend the school.
Parameter = Proportion of students named by president correctly.
Step-by-step explanation:
Population for a particular study is the largest possible group of individuals that are essential to be considered.
Parameter = measure of characteristic in a population.
By the above definition, we have
Population = Total students attend the school(1800).
Parameter = Proportion of students named by president correctly.
