Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 1, and the given zeros.

Licemer1 [7]

Answer:

The MEDIAN, 4.5 hours, is the best measure of center, so the IQR is the best measure of variability.

McKennas conclusion IS NOT accurate. The mode of her data IS 6 hours. However, MORE than half of the time, she spends LESS than 6 hours riding her horse. It would be more accurate to say that Mckenna typically rides her horse between 2.5 and 6 hours.

Step-by-step explanation:

Put the values in order of smallest to largest:

0, 2, 2, 2.5, 2.5, 3, 4, 5, 6, 6, 6, 8, 9, 10

Median (middle value) = (4 + 5)/2 = 4.5

Lower quartile Q1 = 2.5

Upper quartlie Q3 = 6

IQR = Q3 - Q1 = 3.5

Mode (value that occurs most often) = 6

Mean (average) = sum of values ÷ number of values = 4.7

Range (difference between the highest and lowest values) = 10 - 0 = 10

Median is the best measure of the center since it isn't influenced by extreme values.

IQR is less affected by outliers and extreme values. It gives a consistent measure of variability for skewed data.

The MEDIAN, 4.5 hours, is the best measure of center, so the IQR is the best measure of variability.

McKennas conclusion IS NOT accurate. The mode of her data IS 6 hours. However, MORE than half of the time, she spends LESS than 6 hours riding her horse. It would be more accurate to say that Mckenna typically rides her horse between 2.5 and 6 hours.

In a bag of apples, the ratio of red apples to green apples is 3:4. If the bag contains 60 red apples, how many green apples are

alekssr [168]

Hi there! The answer is 80 green apples.

In a bag of apples, the ratio of red apples to green apples is 3:4, so we must first realise that there is a total of 7 parts.

3 of these parts constist if red apples. In other terms 3 / 7 equals 60. Now divide by 3 to find 1 / 7. Hence, 1 / 7 equals 60 / 3 = 20 apples.

4 of the total 7 parts consist of green apples, so we must multiply the preceding outcome by 4 to find our answer. 4 / 7 equals 20 × 4 = 80 apples.

Therefore, there are 80 green apples in the bag.
~ Hope this helps you!
