Answer:
x = 4
Step-by-step explanation:
It is given that
, and we have to solve the given equation for x.
Now, we have
Squaring both sides we get
⇒ x - 3 = x + 6√x + 9 {Since we know the formula of (a + b)² = a² + 2ab + b²}
⇒ 6√x = - 12
⇒ √x = -2
Again squaring both sides we get
⇒x = 4 (Answer)
Answer:
1 and 5 out of 12
Step-by-step explanation:
Katie:9/12
Tori:8/12
9+8 =17/12 = 1 and 5/12 and this is already in the simplest form
The sample size must be 543 so the sample proportion is will not differ by 5%
We are given the following in the question:
Margin of error = 5%
Confidence interval:
p ±z√(p'(1 - p')/n)
Margin of error =
p = ±z√(p'(1 - p')/n)
Since no particular proportion is given, we take
p' = 0.5
Z critical at α 0.02 is ± 2.33
Putting values, we get,
p = ±z√(p'(1 - p')/n)
2.33 x √(0.5(1 - 0.5)/n)
√n = 2.33x 0.5/0.05
n = 542.89 = 543
Thus, the sample size must be 543 so the sample proportion is will not differ by 5%

Answer:
The answer to this problem would be 900$.
WHY?:
I already did this question myself!!
Answer:
14 x (2 + 5)
Step-by-step explanation:
This is because 2 and 5 do not have a factor greater than 1
