Answer: $24.38
Step-by-step explanation:
So since the cost of a movie ticket is $20 and the cost is predicted to increase by 2% each year over the next 10 years. to find the cost after 10 years you want to solve for x.
so x=20(1.02)^10
20 is the initial cost and 0.02 is the rate of growth. expressed as a decimal number, the base is b=1+0.02=1.02 and the exponent 10 is the number of years
Base = 8 + 2x
Height = 14 - x
Expression for area of the triangle:
1/2(8 + 2x)(14 - x)
Hope this helps!
Answer:
For a data set of N elements:
{x₁, x₂, ..., xₙ}
The mean is:
The mean absolute deviation is:
And the population standard deviation is:
In this case, our set has 5 elements, and the set is:
{2, 4, 6, 9, 14}
The mean of this set is:
The mean absolute deviation is:
And the population standard deviation is:
Answer:
The slope of the line is -5/4
Step-by-step explanation:
19) = Solution :-
5x+4y = 20
Let's keep x's value 0,
so
we get,
5x+4y = 20
or, 5×0+4y = 20
or, 4y = 20
so, y = 5
one coordinate we get (0,5)
Again
Let's keep x's value 4,
we get,
5x+4y = 20
or, 5×4+4y = 20
or, 20+4y=20
or, 4y = 0
so, y = 0
Another coordinate, we get (4,0)
now
slope(m) = (y2-y1)/(x2-x1)
= (0-5)/(4-0)
= -5/4
