We're given
which immediately tells us that
In other words, swapping the limits of the integral negates its value.
Also,
The integral we want to compute is
which we can do by splitting up the integral at x = 4 and using the known values above. Then the integral we want is
Answer:
33
Step-by-step explanation:
Since the ratio is 5:3, there is a difference of 2. Divide 22 with 2 and get 11. Each ratio unit it 11. Multiply 11 with 3 to get 33 girls, and with 5 to get 55 boys
Answer:
-
6 13/18
Step-by-step explanation:
5/9 times -4 is -20 over 9 -20/9 -2 2/9
3/4 times -6 is -18 over 4 -18/4 -4 1/2
You need them to have a common denominator
so you can multiply the first answer by 4 and the second by 9.
You get -242/36 after a while
and then
you simplify.
You can multiply 36 six times into -242 so you get the whole number of 6 plus 216
242-216 is 26
26 over 36 is 13 over 18
-6 13/18
Answer:
1. Statistical Inference
2. Variability.
3. Outlier.
4. Population.
5. Sample.
Step-by-step explanation:
1. <u>Statistical Inference</u>: Reasoning from a sample to a population. For example, the average common entrance score of all examinees (population l) in New York city or a business that collects data from a random sample of 100 consumers and recorded whether they are male or female.
2. <u>Variability</u>: Successive observations of a system or phenomenon do not produce exactly the same result. For instance, the distribution having the same value of mean can have varying variability.
3. <u>Outlier</u>: An observation that differs considerably from the main body of the data. For example, in the following scores 1, 2, 3, 4, 50, 5, 60; both 50 & 60 is an outlier.
4. <u>Population</u>: The entire collection of objects or outcomes about which data are collected. For example, the number of new born babies in a hospital, the total number of football players in a soccer league.
5. <u>Sample</u>: A subset of the population containing the observed objects or outcomes and the resulting data from these objects or outcomes. For example, the average height of girls in a class having a population of 10 boys and 20 girls.
