Answer:
Let x be how far from the tower can it be placed
by Pythagorus theorem
x^2 + 96^2 = 105^2
x=√(105^2 -96^2 )=√1809 = 42.532340 = 42.5 ft
Add 0.2x to both sides
1.2x+0.7= 1
1.2x=.3
x=.3/1.2
x=.25
option #2
subtract .7 on both sides
x=1-.7-.2x
x=.3-.2x
1.2x=.3
x=.25
13 gallons in 14 minutes. The unit rate is..
.921 gallons in a minute. if your multiplying by 4. that would equal 3.684. which is rounded to 3 gallons.
So first you would plug 3 into the x values in the equation. (3)+1/2+15-1/2. EVALUATE AND THE ANSWER IS 18!!
The sample standard deviation is (B) $3.16.
<h3>
What is the sample standard deviation?</h3>
- The sample standard deviation is defined as the root-mean-square of the differences between observations and the sample mean: A significant deviation is defined as two or more standard deviations from the mean.
- The lowercase Greek letter (sigma) for the population standard deviation or the Latin letter s for the sample standard deviation is most commonly used in mathematical texts and equations to represent standard deviation.
- For example, if the sample variance for a frequency distribution of hourly wages is 10 and the sample standard deviation is $3.16.
Therefore, the sample standard deviation is (B) $3.16.
