please someone help me with these questions fast
Answers
Answer:
2)d
3)c
4)b
5)a
Step-by-step explanation:
2)
7p+q = 3 is not a linear equation in one variable because it has two variables p and q.
3)
Given observations are 3,5,1,2,0,2,3,5,0,2,1,6
On writing them into ascending order
=> 0,0,1,1,2,2,2,3,3,5,5,6
The most frequent occuring observation = 2
It occurs 3 times
Mode = 2
4)
The first 7 natural numbers are 1,2,3,4,5,6,7
Sum of the observations = 1+2+3+4+5+6+7 = 28
Number of all observations = 7
We know that
Mean = Sum of all observations/Number of all observations
=> Mean = 28/7
=> Mean = 4
The mean of first 7 natural numbers = 4
5)
Arranging the numerical figures of a data in ascending or descending order is called an Array.
6)
a) Four less from thrice a number m is 14
=> 3m - 4 = 14
b) x exceeds 3 by 7
=> x = 3+7
=> x = 10
7)
Given observations are 21,16,30,15,16,18,10,24,26,20
Lowest value = 10
Greatest value = 30
We know that
Range = Heighest value-Lowest value
=> Range = 30-10 = 20
Therefore Range of the data = 20
8)
Two algebraic expressions combined with an equality sign is called an equation.
or
The equality of two algebraic expressions is called an equation.
9)
Given equation is 4(x+1) = 4
=> x+1 = 4/4
(Transposing 4 to RHS)
=> x+1 = 1
=> x = 1-1
(Transposing 1 to RHS)
=> x = 0
Therefore, The solution for the given equation is 0
