Answer:
5
Step-by-step explanation:
First multiply inside of the parenthesis with 3 then add the like terms
3x + 6 - 6 = 15 ➡ 3x = 15 divide both sides with 3 and x = 5
Answer:
111 spots
Step-by-step explanation:
Let y denote the total number of parking spots expressed as:
Given that x is the number of spots in the first row.
-Now, given that the first row has 32 spots, we substitute in the expression to solve for y:
Hence, there are 111 spots in the parking lot.
The trend of the plotted points has a positive slope, so we can eliminate -0.95 and 0. Next we need to determine how strong the correlation is from a scale of -1 to 1 where the strongest is closer to -1 or 1.
Since we cannot draw a line through all of the points, the answer cannot be 1.
Between 0.75 and 0.95, we should go with 0.95 because if we were to draw a best fit line through the points, most of them would be close to or on the line. If the answer was 0.75, the correlation would be much weaker.
So the answer is 0.95.
