The reason why Fiona cannot make a valid prediction based on the mean of the population is that the variation of Fiona’s samples is too large.

<h3>Why can't Fiona use the means she recorded?</h3><h3 />

Mean is quite sensitive to outliers so it is best used when the variation between variables is not too much.

In Fiona's case, there variation is quite high with high variable of 95 compared to a low value of 45.

What is the answer to:<br><br>3(3x-4)-2(2x-1)
Tamiku [17]

Answer:

= 5x -10

Step-by-step explanation:

=(3)(3x)+(3)(−4)+(−2)(2x)+(−2)(−1)

=9x+−12+−4x+2

Combine Like Terms:

=9x+−12+−4x+2

=(9x+−4x)+(−12+2)

=5x+−10

Can someone plssss answer these I’m so confused I’m begging u I’l love u foreve
madam [21]

Answer:

22) RT ; angles 2 and 4 are alternate interior angles

23) RT ; angles 1 and 3 are alternate interior angles

24) TV; same-side interior angles (some classes called them consecutive interior angles)

25) RV; same-side interior angles (some classes call them consecutive interior angles)

Step-by-step explanation:

The transversal is the a "line" going through at least 2 others helping to form the angles in question.

22) The line segment going through two line segments that contain angles 2 and 4 is:

RT.

Angles 2 and 4 are alternate interior angles because they happen inside the parallel lines on opposite sides of the transversal at the different intersections of RT and the parallel lines it goes through.

23) The line segment going through at least two line segments that contain angles 1 and 3 is:

RT.

Angles 1 and 3 are alternate interior angles because they happen inside the parallel lines on opposite sides of the transversal at the different intersections of RT and the parallel lines it goes through.

The cool thing about 24 and 25 is that they give you the transversal in the name of the angle.

24) Angles TVR and VTS are being formed by the line segment TV and the parallel line segments that it intersects.  TV is the transversal.

Angles TVR and VTS are same side interior angles because they happen inside the parallel lines on the same side of the transerval at the different intersections of TV and the parallel lines it goes through.

25) Angles SRV and RVT are being formed by the line segment RV and the parallel line segments that it intersects.  RV is the transversal.

Angles SRV and RVT are same side interior angles because they happen inside the parallel lines on the same side of the transerval at the different intersections of RV and the parallel lines it goes through.

Insert three arithmetic means between 25 and 9​
Aleonysh [2.5K]

Answer:

21, 17, 13

Step-by-step explanation:

Find the mean of the 2 given values

mean = \frac{25+9}{2} = \frac{34}{2} = 17

Noe find the mean of 25 and 17 and 17 and 9

mean = \frac{25+17}{2} = \frac{42}{2} = 21 and

mean = \frac{17+9}{2} = \frac{26}{2} = 13

Thus the 3 means are 21, 17 and 13, that is

25, 21, 17, 13, 9
