Answer:
B. x ≥ -3
Step-by-step explanation:
-4 x - 10 ≤ 2
add ten by both sides
-4x≤12
divide -4 by both sides
x ≤ -3
BUT because you divded you have to switch the sign so
x ≥ -3
Answer:
There are a 25% probability that Christine fails the course.
Step-by-step explanation:
We have these following probabilities:
A 50% probability that Christine finds a tutor.
With a tutor, she has a 10% probability of failling.
A 50% probability that Christine does not find a tutor.
Without a tutor, she has a 40% probability of failing.
Probability that she fails:
10% of 50%(fail with a tutor) plus 40% of 50%(fail without a tutor). So
There are a 25% probability that Christine fails the course.
Answer:
b = d/(2ac)
Step-by-step explanation:
10abc - 2d = 3d
Add 2d to each side
10abc - 2d+2d = 3d+2d
10 abc = 5d
Divide each side by 10ac
10 abc/ (10ac) = 5d/10ac
b = d/(2ac)
A statement which does not describe a characteristic of the line of best fit for a scatter plot is that: A. the line of best fit should be the average of all the data points.
<h3>What is a scatter plot?</h3>
A scatter plot can be defined as a type of graph which is used for the graphical representation of the values of two variables, with the resulting points showing any association (correlation) between the data set.
<h3>What is a line of best fit?</h3>
A line of best fit is also referred to as a trend line and it can be defined as a statistical (analytical) tool that is used in conjunction with a scatter plot, in order to determine whether or not there's any correlation between a data.
<h3>The characteristics of a
line of
best fit.</h3>
The statements which describe a characteristic of the line of best fit for a scatter plot include the following:
- The line should be as close to the points as possible.
- The number of points above the line should be equal to the number of points below the line.
- The distance between the points above the line and the line should be relatively equal to the distance between the points below the line and the line.
