Answer:
The sample size is
Step-by-step explanation:
From the question we are told that
The lower bound of the range is a = 51
The upper bound of the range is b = 710
The margin of error is
Generally the standard deviation is mathematically represented as
=>
=>
From the question we are told the confidence level is 95% , hence the level of significance is
=>
Generally from the normal distribution table the critical value of is
Generally the sample size is mathematically represented as
=>
=>
Answer:
perimeter = 12x+10 area=8x^2+14x+6
Step-by-step explanation:
A
2x+2+2x+2+4x+3+4x+3
2x+2x+4x+4x+2+2+3+3
4x+4x+4x+2+2+3+3
8x+4x+2+2+3+3
12x+2+2+3+3
12x+4+3+3
12x+7+3
12x+10
B
(2x+2)(4x+3)
8x^2+8x+6x+6
8x^2+14x+6
Step-by-step explanation:
step 1. use Foil to multiply the polynomials.
step 2. (3x + 3)(2x + 6) = 6x^2 + 18x + 6x + 18 = 6x^2 + 24x + 18.
step 3. (2x + 1)(x - 2) = 2x^2 - 4x + x - 2 = 2x^2 - 3x - 2.
step 4. (x - 3)(x + 4) = x^2 + 4x - 3x - 12 = x^2 + x - 12.
