X^2-(2)(x)(4)+16-7=0
x^2-(2)(x)(4)+4^2 =7
(x-4)^2=7
So value of p is 4 and q is 7
Answer:
A) M = 3.016
B) M = 9.79
C) 62
Step-by-step explanation:
A) We are given;
Population size; n = 100
standard deviation; σ = 12
Formula for the margins of error is;
M = z × σ/√n
At 99% confidence interval, z = 2.58
Thus;
M = 2.58 × 12/√100
M = 3.016
B) n is now equal to 10, thus at same confidence interval used in option A, we have;
M = 2.58 × 12/√10
M = 9.79
C) to solve this, we will use the formula;
n ≥ (zσ/m)²
Where;
z at 95% confidence interval has a value of 1.96
m is the margin of error = 3
Thus;
n ≥ (1.96 × 12/3)²
n ≥ 61.4656
Thus,approximately n = 62
Answer:
7x - 4
Step-by-step explanation:
-2x + (9x - 4)
-2x + 9x -4
9x - 2x = 7x
7x - 4

Answer:
The dividend is 51 and the divisor is 13.
Step-by-step explanation:
Since the remainder is 12, so the divisor must be greater than 12.
So, we can choose any number as a divisor which is greater than 12.
Assume the divisor is 13.
So, when we divide the dividend say, x by the divisor 13 then the quotient will be 3 and the remainder will be 12.
Therefore, x = 13 × 3 + 12 = 51
So, the dividend is 51 and the divisor is 13. (Answer)
