Answer: The regression equation could have a positive or a negative slope

Explanation:

The coefficient of determination is marked as r^2. This is always positive because squaring a negative leads to a positive. Knowing something like r^2 = 0.7 does not tell us whether r itself is positive or negative, so we don't know if the regression line slope is positive or negative. We would need more info.

HELP is this graph misleading? Be sure to justify your answer with mathematical reasoning
victus00 [196]

A graph is used to visualize data using plots, figures and charts.

The given graph is not misleading

<h3>How to determine if the graph is misleading</h3>

From the figure, we have the following highlights

  • The graph is well labelled on both axes
  • The y-axis (which represents a numerical data) have a constant interval i.e. the scale is consistent
  • All points are properly connected

Using the above properties, we can conclude that the graph is not misleading

Three coins are flipped
RUDIKE [14]

Answer:

probability of getting no heads: 1/ 8

probability of at least two tails: 1/4

Step-by-step explanation:

To calculate the probability of getting no heads, multiply the probability of not getting heads for each coin. A coin has two sides: heads and tails; the probability of not getting heads would be 1/2.

1. Multiply the probabilities for each coin

1/2 · 1/2 · 1/2 = 1/8

To calculate the probability of getting at least two tails, multiply the probability of getting tails for two coins and the probability of flipping either heads or tails for the remaining coin. Because it is at least two tails, the remaining coin can flip to either heads or tails.

1. Multiply the probabilities for each coin

1/2 · 1/2 · 2/2 = 1/4
