Answer:
Step-by-step explanation:
Answer: y = 2/3x + 5
Step-by-step explanation:
y = mx + b
Starting with a head start of 5 m would give you b (initial y value). The slope (m) is how many meters per second which is 2/3. So, the equation would be y = 2/3x + 5.
The x is the independent and the y is the dependent.
Answer:
Yes, the student is right
Step-by-step explanation:
95% confidence interval for the mean ideal weight given by adult American women is 139 (+ or -) 1.4 pounds
Mean = 139 pounds
Error margin = 1.4 pounds
Lower limit = 139 - 1.4 = 137.6
Upper limit = 139 + 1.4 = 140.4
The ideal weight is between 137.6 and 140.4 pounds
