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
It's right triangle 45 45 90
The sides in this triangle<span> are in the ratio 1 : 1 : 1√2
if one side = </span>2√2 then b = 2√2
hypo. a = b(√2) = 2(2√2) = 4√2
answer
a = 4√2
b = 2√2
Answer:
Step-by-step explanation:
ok teacher make these kind of questions very hard but they are very easy here we go
if there is only 6 boys that means there are 14-6=8 girls
so the ratio of girls to boys is 8:6
know when it says all students we have to include girls too
so in a class of 14 there are 6 boys and 8 girls
14:8 is our answer
