Answer:
Absolute error = $25
Step-by-step explanation:
Given that:
Amount spent by John on shopping trip = $75
Estimated amount to spent on shopping trip = $100
Absolute error = Approximate value - Exact value
Here,
Approximate value = $100
Exact value = $75
Absolute error = 100 - 75
Absolute error = $25
Percentage = 
Percentage = 
Percentage = 33.33%
Hence,
Absolute error = $25
Use the quadratic formula to solve
x = -1, -9
two solutions are possible
Answer:
Step-by-step explanation:
Recall that an expression that can be factored as (U+V)(U-V) using distributive property for multiplication of binomials, should render: 
(the factorization given above is that of a difference of squares. Then, the idea is to write the original expression :
as a difference of perfect squares. Let's examine each term and its numerical and variable form to find if they can be written as perfect squares:
a) the term 
therefore, if we assign the letter U to 
, the first term becomes:
b) the term 
therefore, if we assign the letter V to 
, this second term becomes:
With the above identification, our expression can now be factored as a difference of squares:
Hey there, well we know a prime number must have exactly two factors, which is 1 and its self. 2 is the lowest prime number because because the common divisors for 2 is 1 and 2. Therefore, 2 is the lowest prime number.
Answer:
67.49
Step-by-step explanation:
Let the number of HCF be x.
Let the cost be y.
You are given 2 points of a line: (15, 32.84) and (43, 79.04).
Now we find the equation of the line that passes through those points.
y - y1 = m(x - x1)
y - 32.84 = [(79.04 - 32.84)/(43 - 15)](x - 15)
y - 32.84 = (46.2/28)(x - 15)
y - 32.84 = 1.65(x - 15)
y = 1.65x - 24.75 + 32.84
y = 1.65x + 8.09
Now we let x = 36 and solve for y.
y = 1.65(36) + 8.09
y = 67.49
