Let's plug the values in the formula

Percent error is the difference in percent between the estimated cost and the actual cost. So in this case the percent difference between 50 and 65. to find this we need to find out what percent the estimated cost is out of the actual cost, So what percent is 50 out of 65? We can find this by doing the equation 50 / 65, which is 0.76923076923.
This rounds to 0.77, which is 77%
So this means 77% is 50, and 100% is 65. So what is the difference? 100 - 77 = 23. So 23% is your answer.
Answer: 23% error.
Step-by-step explanation:
Percentage error = error in cost/actual cost X 100
Error = $65 - $50
= $15
Therefore, percent error
= 15/65 x 100
= 15 x 100/65
= 1500/65
= 23.07
Therefore, to the nearest whole %
= 23% error.

The equivalent multiplication expression for 3^3 without using exponents is 3 x 3 x 3. Exponentiation is a mathematical operation in which the base number gets multiplied by itself as many times as specified by the exponent.
Explanation:
The expression
3^3
in mathematics is essentially stating that the number 3 should be multiplied by itself twice. So, without using exponents, an equivalent multiplication expression would be
3 x 3 x 3
. This is because exponentiation is a mathematical operation in which the base number gets multiplied by itself for the number of times specified by the exponent.

Answer:
The equation of line perpendicular to given line and passes through points ( - 1 , 4 ) is 2y = -3x + 5
Step-by-step explanation:
Given line equation as :
3 y = 2 x - 1
Or, y = x -
So , The equation is in the form of y = m x + c
Where m is the slope of the line
∴ satisfying the condition
Slope of given line is m =
Now , ∵ The other line is perpendicular to this line and passes through point ( - 1 , 4 )
Let , Slope of other line = M
∴ for perpendicular line condition , products of the slope = - 1
I.e m × M = - 1
Or , M = -
Or M = -
Or M = -
Thus The equation of line with slope M and passing through points ( - 1 , 4 ) is
or, (x + 1)[/tex]
or, 2y - 8 = - 3 (x +1)
Or, 2y - 8 = - 3x - 3
or 2y = - 3x - 3 + 8
∴ 2y = -3x + 5
Hence The equation of line perpendicular to given line and passes through points ( - 1 , 4 ) is 2y = -3x + 5 Answer
