Answer:
Option C) The symbol y represents the predicted value of price.
Step-by-step explanation:
We are given the following in the question:
We find a regression equation with x representing the ratings and y representing price.
The equation has a slope of 130 and a y-intercept of 350.
Comparing with the slope intercept form:
Thus, we can write the equation as:
Here, y is the predicted variable that is the price, c is the price of hotel when a rating of 0 is given.
Thus, symbol y represents:
C) The symbol y represents the predicted value of price.
Answer:
1 dimes and 9 quarters
Step-by-step explanation:
9 quarters = 2.75
1 dime = 10c
all together equals 2.85
Albert´s ftather age=x
Albert age=y
We suggest this system of equations:
y=x-24
x+8=2(y+8)
we solve this system of equation by substitution method.
x+8=2[(x-24)+8]
x+8=2(x-16)
x+8=2x-32
x-2x=-32-8
-x=-40
x=40
y=x-24
y=40-24
y=16
Answer: Albert´s father is 40 years old, and Albert is 16 years old.
Answer:
Should be a 33.33% increase
Step-by-step explanation:
320 divided by 240 to get 1.33, anything above 1 is increase, so its a 33% increase.
So the ratio is at ¼ : 12, namely the drawing has ¼ inch to an actual 12 feet.
so, what would it be for an actual 15 feet on the drawing then?
