I got the answer 8x^3+1 by putting the values in the above formula
The answer is : 5 .
Step by step solution:
Let the width of the rectangle be x.
Width : x
Length : x + 2
x + x + 2 + x + x +2 = 24
4x + 4 = 24
4x = 24-4
4x = 20
x= 20/4
x=5
If we call the number x, we can write an equation to solve:
6(x - 4) = 12
6 × x = 6x
6 × -4 = -24
So you get 6x - 24 = 12
6x - 24 = 12
+ 24
6x = 12
÷ 6
x = 2
And your final answer is 2, I hope this helps!
Answer: 68
Step-by-step explanation:
Formula for sample size when prior estimate of population proportion (p) is available: 
, where z*= critical-value.
E= Margin of error.
Let p be the population proportion of trees are infected with the citrus red mite.
As per given , we have
E= ± 0.08
The critical z-value corresponding to 90% confidence level = z*=1.645
Substitute all the values in the above formula , we get
Required sample size :
[Rounded to next integer.]
Thus, the minimum sample size should be taken =68
