Answer:
the speed value produced by the radar equipment.
Step-by-step explanation:
In an experiment, a random variable is typically referred to as a dependent variable. In this context, the random variable pertains to the speed value produced by the radar equipment. This value is reliant on the actual speeds of the cars that go past the equipment. A higher speed results in a greater value shown by the radar. Thus, it relies entirely on the automobiles.
2ab x cos(C) = 7 since
a^2 + b^2 - 2ab x cos(C) = c^2
2ab x cos(C) = a^2 + b^2 - c^2
2ab x cos(C) = 2^2 + 2^2 - 1^2
2ab x cos(C) = 7
Answer:
The regression line is not an appropriate model due to the existence of a pattern in the residual plot.
Step-by-step explanation:
A residual plot has been provided for a certain data set.
The residual plot indicates a scatter relationship between x and y.
The plotted points demonstrate that a linear relation is unlikely; it appears to be more parabolic or exponential in nature.
This suggests the regression line is not a suitable model as the residuals do not converge towards 0.
Additionally, a linear trend pattern is absent.
D) The regression line is not a suitable model as it exhibits a pattern in the residual plot.
Response: The following comparison is made.
Detailed explanation:
At the playground, a climbing structure is 6 feet high and stretches 4 feet horizontally.
The slope can be calculated as vertical height divided by horizontal length.
= 6/4 = 3/2 = 1.5
In contrast, a climbing structure in the gym stands 10 feet tall, extending 6 feet horizontally.
Therefore, slope, 
= 10/6 = 5/3 = 1.67 (approximately)
As such, <
Thus, the slope of the first climbing structure is less than that of the second.
The question requires completion since the inventory data is absent.
