Answer:
Positive correlation exists ;
Number of Steps taken will cause heart rate to increase.
Step-by-step explanation:
Correlation refers to the relationship which exists which exists between two variables. It shows how an increase in one variable affects the other variable. Variables are divided into independent and dependent variables. Correlation may either be positive, negative or non - existent.
Given the correlation Coefficient of 0.88 between heart rate and number of steps taken, the R value being close to 1 depicts a strong positive relationship or correlation.
Correlation between number of steps taken and heart rate.
Yes, The number of steps taken will cause the hear rate to increase. Hence, the dependent variable is is heart rate and it depends on the number of steps taken (independent variable).
Answer:
The translation would be just a change in where the vertex would be.
The change in x value would be that it would go to the left 6. The change in y would be that in would go down 9.
Step-by-step explanation:
To find this use the vertex form base to determine the vertex of either equation. Using this equation, the vertex is always (h, k)
y = a(x - h)^2 + k
y = (x - 5)^2 + 7
VERTEX (5, 7)
y = a(x - h)^2 + k
y = (x + 1)^2 - 2
VERTEX (-1, -2)
Knowing these two, we can see that the x value goes back by 6 and the y value goes down by 9
