Answer: 2185
Step-by-step explanation:
Let p be the proportion of visitors are campers.
Given : The Tennessee Tourism Institute (TTI) plans to sample information center visitors entering the state to learn the fraction of visitors who plan to camp in the state.
The prior proportion of visitors are campers : p=0.35
Allowable error : E= 2%= 0.02
We know that the z-value for 95% confidence = 
Then by Central Limit Theorem , the required sample size would be :
Simply , we get
[Rounded to the next whole number.]
Hence, the smallest sample size to estimate the population proportion of campers =2185
Answer:
w = y - x is the equation to find w
Where,
w = Weight of the liquid
x = Weight of the empty can
y = Weight of the can with liquid
Step-by-step explanation:
Let
Weight of the empty can = x
Weight of the liquid = w
Weight of the can with liquid = x + w = y
x= 30 grams
w = ?
y= 47.3 grams
y = x + w
w = y - x
= 47.3 - 30
= 17.3
w= 17.3 grams
Therefore, the weight of the liquid is 17 .3 grams
Answer:
40
Step-by-step explanation:
20 + 2.5x = 3x
20 = 0.5x
x = 40
w=Washington monument steps
w= 27-6s so the expression is w= 6s-27
The one with the variable always goes first.

Answer:
Step-by-step explanation:
Let
x ----> the number of lions
y ----> the number f tigers
z ----> the number of zebras
we know that
----> equation A
Remember that
To find out the number of lions, multiply the total animals by the percentage of lions
To find out the number of zebras, multiply the total animals by the percentage of zebras
Substitute the value of x and the value of z in equation A and solve for y
