Answer:
i dont remember how to do this and i just did this last year
Step-by-step explanation:
Answer:
The value is 8500
Step-by-step explanation:
Of means multiply and is means equals
6% * V = 510
Change percent to decimal form
.06V = 510
Divide each side by .06
V = 510/.06
V =8500
Answer: 271
Step-by-step explanation:
The formula we use to find the sample size is given by :-
, where 
is the two-tailed z-value for significance level of 
p = prior estimation of the proportion
E = Margin of error.
If prior estimation of the proportion is unknown, then we take p= 0.5 , the formula becomes
Given : Margin of error : E= 0.05
Confidence level = 90%
Significance level 
Using z-value table , Two-tailed z-value for significance level of 
Then, the required sample size would be :
Simplify,
Hence, the required minimum sample size =271
To divide fractions be multiply by the resiprical
4 6 24
--- x ---- = ------
1 7 7
then simplify into a mixed number
3 3/7
Complete question is;
An architect plans to build an extension to meiling's rectangular deck. Let x represent the increase, in meters, of her deck's length. The expression 4(x+8) represents the area of the deck, where 4 is the width, in meters, and (x+8) represents the extended length, in meters. Use distributive property to write an expression that represents the total area of meilings new deck.
Answer:
4x + 32
Step-by-step explanation:
We are told that the expression 4(x+8) represents the area of the deck.
Also, that 4 is the width, in meters, and (x+8) represents the extended length, in meters.
Thus, area is;
A = 4(x+8)
Using distributive property simply means we will distribute the term outside the bracket to each term inside the bracket.
Thus;
A = (4 * x) + (4 × 8)
A = 4x + 32
