Answer:
40
Step-by-step explanation:
y = 50 + .4 x 40
y = 30 + .9 x 40
y = 66 for both equations
Answer: The scatterplot shows a positive correlation because the values of y increase as the values of x increase.
Which of the following is the best approximation of the correlation coefficient for the data displayed in the scatterplot? 0.5
Answer:
Please include a photo of model please!
Step-by-step explanation:
He will do both in 12 days since the least common multiple of 3 and 4 is 12. This can be found by making a list of both numbers' multiples. You will see that the first common number or multiple is 12.
Multiples of 3: 3, 6, 9, 12, 15
Multiples of 4: 4, 8, 12, 16, 20
Hope this helped
Yes, you can use a method other than graphing to solve a system of equations. One of the most common ways is to use matrices. When you solve the matrix, you solve for the point of intersection.
