X/3=60
then multiply each side by 3 and x will equal 180
E. negative one property of multiplication.
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:
Step-by-step explanation:
let number of passion fruits=x
number of dragon fruits=x+10% of x
=x+0.1 x=(1+0.1)x=1.1 x
total number of fruits=x+1.1 x=(1+1.1)x=2.1 x
1.1x+60% of 1.1x+x+9% of x=2.1x+75
1.1 x+0.6 of 1.1 x+x+0.09 of x=2.1x+75
1.1x+0.66 x+x+0.09 of x =2.1x+75
2.1 x+0.75x-2.1 x=75
0.75 x=75

Given :
Perimeter of rectangular filed , P = 316 yards.
The length of the field is 4 yards less than twice its width.
To Find :
The dimensions of the playing field.
Solution :
Let, width be x.
So, by given condition length will be 2x - 4.
Perimeter is given by :
P = 2( l + b )
316 = 2( 2x - 4 + x )
3x - 4 = 158
x = 54 yards.
So, the dimensions are 54 yards and 104.
Hence, this is the required solution.
