Answer:
Step-by-step explanation:
If you want the surface area of a rectangular prism, then you'll use a formula resembling this:
A = 2(area of end) + 2(area of top) + 2 (area of side).
Example: suppose the dimensions of the prism are 3 in by 5 in by 8 in.
Then the total surface area is:
A = 2(3*5) + 2(3*8) + 2(5*8) square inches, or 2(15) + 2(48) + 2(40) sq in, or
A = 30 + 96 + 80 sq in, or A = 206 sq in
Answer:
f(4) = 9
Step-by-step explanation:
f left parenthesis x right parenthesis equals x squared minus 3 x plus 5
f(x) = x² - 3x + 5
f left parenthesis 4 right parenthesis equals
f(4) =
f(x) = x² - 3x + 5
When x = 4
f(4) = 4² - 3(4) + 5
= 16 - 12 + 5
= 9
f(4) = 9
I’m a bit confused. can you please explain in more detail?
Answer:
The y-intercept for this equation makes no sense for this model.
Step-by-step explanation:
In this case, the explanatory variable x is the year when the observations were taken. So, the values are the integer numbers between (and including) 1975 and 1986.
The<em> y-intercept for the equation of the linear regression makes no sense for this prediction</em>, for it would correspond to the value x=0 (the year 0) is not consider in the range of the explanatory data.
Answer: A: He payed 3 dollars in sales tax B: He payed 27.59 for his ticket
Step-by-step explanation:
A: 42.99 + 7% = 45.99 - 42.99 + 3
B: 42.99 - 40% = 24.79 + 7% = 27.59
