Answer:
x = 9
Step-by-step explanation:
Well, let's solve it!
x - 9 = 0
Let's add 9 to both sides to isolate the variable and maintain equality.
We end up with :
x = 9 since -9 and 9 cancel out and 0 + 9 = 9.
Answer:
12 ft
Step-by-step explanation:
use the pythagorean theorem to write the equation c^2=(7.2)^2+(9.6)^2, then solve for c with a calculator (if you can use one)
4,034.06 ,5,965.94 are confidence interval for the population average wages at the factory.
What is confidence interval estimation?
Your estimate's mean plus and minus the range of that estimate's fluctuation is called a confidence interval.
If you repeat your test, you can expect your estimate to fall between these numbers with a reasonable degree of certainty. Another term for probability in statistics is confidence.
The formula for confidence interval estimation is:
μ = M ± Z(sM)
where:
M = sample mean
Z = Z statistic determined by confidence level
sM = standard error = √(s2/n)
M = 50000
Z = 2.58
sM = √(30002/64) = 375
μ = M ± Z(sM)
μ = 50000 ± 2.58*375
μ = 50000 ± 965.94
μ = 4,034.06 ,5,965.94

Answer:
$31.56
Step-by-step explanation:
$9.85 × 4 = $39.40
$39.40 25% off is $29.55
6.75% rounded to the nearest cent 6.80%
Sales tax is $2.01
$29.55 + $2.01 = $31.56
Answer:
Step-by-step explanation:
let : f(x) = (x²-x+1)/x+1
limf(x) = lim(x²/x) = limx = - -∞ and limf(x) =+ ∞
x → - -∞ x → +∞
lim/f(x)/ = ∞ ....... x = 1 is the line asymptote
limf(x)/x = 1
x → + -∞
lim (f(x) -x ) = -1 .....so y =x -1 is the second line asymptote
x → + -∞
x → 1
