Answer:
4.756 miles
Step-by-step explanation:
It is given that,
The running trail in the local park is 3.416 miles long. If the park board were planning to extend the trail by 1.34 miles.
We need to find the new length of the running trial. It is equal to the sum of length of running trail and the extended length. So,
l = 3.416 +1.34
l = 4.756 miles
So, the new length of the running trail be 4.756 miles
The answer to the question is 9
Answer:
As in an equilateral triangle all sides are equal so 9+3x = 5x-5
9+3x = 5x-5
9+5 = 5x-3x
14 = 2x
14/2 = x
7= x
So,As we know that x is 15 so we can substitute the values 9+3x or 5x-5
9+3x
=9+3*7
=30
So, one side of the triangle = 30
Perimeter of an equilateral triangle = 3*side
=3*30 = 90
So, perimeter of the equilateral triangle = 90
Answer:
No
Step-by-step explanation:
No, this doesn't make sense because as stated in the problem, each ticket costs $2.50. Since you cant buy part of a ticket, you would have to have a whole number for t. You cannot buy 3.5 tickets.
Answer:
The correct option is b.
Step-by-step explanation:
The formula for standard deviation is

where,
is mean of the data and n is number of observation.
The variance of a stock's returns can be calculated by the above formula.
Variance of stock's returns is the average value of squared deviations from the mean.
Therefore the correct option is b.
