Which relation is a function? Question 3 options: {(1, 2); (1, 3); (1, 4); (1, 5)} {(1, 2); (2, 3); (3, 4); (4, 5)} {(1, 2); (3,

To be a function for every identical x value it has to have a different Y value. If the set has two identical X values but they have different Y values it can't be a function.
The set that is a function is:
{(1, 2); (2, 3); (3, 4); (4, 5)}
Answer:
Statement D is correct.
Step-by-step explanation:
Solution:
Data Given:
Linear Regression Relationship = Speed = 10.3 + 5.4 (hour)
Linear Regression Relationship = y = mx + c
Here,
m = slope = 5.4
c = 10.3 = y - intercept
The correct Answer is D)
Because:
As, the residual value is positive, it means the typist attained faster speed than the model predicted. As we know, residuals is the result of difference between predicted values of the model and data values. On the contrary, if residual would be negative then we would say that typist speed is slower than the model predicted.
Hence, Statement D is correct.
Answer:
ahhh......okay....but I can't see the question...or even the answer!!!
Step-by-step explanation:
Answer:
the plane 2.2 miles away from the runway
Step-by-step explanation:
Given the data in the question and as illustrated in the image below;
from the image, using trigonometric ratio;
SOH CAH TOA
sin = opposite / hypotenuse
sin10° = 0.38 / x
xsin10° = 0.38
x = 0.38 / sin10°
x = 0.38 / 0.173648
x = 2.1883 miles ≈ 2.2 miles { the nearest tenth of a mile }
Therefore, the plane 2.2 miles away from the runway
