I only know of two measures of central tendency. Those are the median and the mean.
The mean is the average value of all numbers in the data set. It is adding up all the number and dividing it by the count of the data set.
The median is found as the middle most value of the data set that is arranged in ascending value.
In this scenario, it is better to use the MEDIAN in Cindy's report to the principal to portray her students in the most favorable manner. The median may either be a C or B. The F grade will not be considered.
Answer:
53.2 kg
Step-by-step explanation:
Let E represent Esther's weight. Then Henry's weight is E/2, and David's weight is E-5.2. Their average weight is ...
((E-5.2) + E + (E/2))/3 = 42.6
2.5E -5.2 = 127.8 . . . . . . . . . . multiply by 3, simplify
2.5E = 133 . . . . . . . . . . . . . . . . add 5.2
E = 133/2.5 = 53.2 . . . . kg
Esther's weight is 53.2 kg.
That are different because that are not!!!!! the same ?
<h3>
Answer: -76 (choice C)</h3>
Explanation:
We're applying the dot product.
u dot v = 3*(-4) + (-8)*8
u dot v = -12 - 64
u dot v = -76
The idea is that we multiply the x coordinates together, and the y coordinates together separately. Afterward you add the products. The result of any dot product is a scalar value, aka a single number.
The dot product is useful in many applications. One of which is to determine if two vectors are orthogonal.
I think it would be <span>51 and 1/3, but I'm not sure</span>
