The answer is C, a function is when the x value does NOT repeat!
Answer: The mean of the data is 278.
Step-by-step explanation:
To the the mean of the data, we’ll have to add all the numbers up and divide it by the amount of data.
275+279+279+276+278+277+280+282+284+270=2780
2780/10=278
Answer with explanation:
Equation of Linear Regression line is
y=1.14 x + 3.805
A line of regression is that line which passes through none of the points, few points or all the points in the two dimensional coordinate plane.It tells value of one variable when another variable is known.
for, x=30
y=1.14 × 30 +3.805
y=34.20 +3.805
y=38.005
y=38 (approx)
So, Ordered pair is , (30,38)
Option B
Hmmm what is now discounted? well, let's assume it sells normally for 499 and is discounted today at 25%, how much is that?
well, if we take 499 to be the 100, how much is 25%?
now, applying the sales tax to the discounted price.
if we take 374.25 to be the 100%, how much is 6.5%?
so, the total cost will then be 374.25 + t.
