Answer:

  30

Step-by-step explanation:

The midpoint of BC will be a distance from line k that is the average of the distances of B and C: (17+13)/2 = 15. Call that midpoint P. We know distance MP is half of distance MA. This same relationship will hold with respect to the distances from P and A to any line through M. That is, the distance from line k (through M) is twice the distance from P to line k: 30 units.

Whats the answer tell me please
ANEK [815]
For y=3x+4, you would put 4 on the y-intercept and from that point you go up 3 and right 1 and then plot the second point.

For y=-x-4, you would put -4 on the y-intercept and from that point go down 1 and right 1 and then plot the second point.

The appropriate measure of central tendency is one that shows

difference and is suitable for a scale that is nominal.

Response:

  • The measure of central tendency to use is the <u>mode</u>.

<h3>How can the appropriate measure of central tendency be selected?</h3>

The mean is the sum of the measurements divided by the number count

of the plants.

The mode is the measurement that has the highest frequency.

The median is the measurement of the middle plant when arranged in a

given order according to size.

To argue that there is a difference between the plants, the measure of

central tendency to use is the mode, given that the data involves

measurements which can be expressed in a nominal scale.

Therefore;

  • The measure of central tendency that will be best for Mrs. Hull to use is the<u> mode</u>
