Answer:
Autocorrelation
Step-by-step explanation:
Autocorrelation seeks to measure the level of correlation between values of the same variables across different observations in the data.
Iva is autocorellating because she wants to measure if students add weight during their first year of college, so the variables she's measuring across broad is the weight which she took at fall then at spring in order to ascertain the difference in the weight in the first year. Measuring of the same variables at different times in order to ascertain changes in the variables measured is autocorrelation.
Taking the square root of both sides of the equation. on e2020
Answer:
your answer would be z= y over w - x
81 Because 3•3•3•3= 81 then I added the negative sign. but I guess you should do -3•-3=9 then again -3•-3=9. then 9•9 equals 81.
Answer:
1/40
Step-by-step explanation:
Probability: (number of ways to achieve the desired result / number of possible results)
For example, if we want a coin to land on heads:
We know there is one way for it to land on heads and two possible outcomes. Thus, the possibility of flipping a head is 1/2.
Using this, we know that there are 5 grey marbles (the desired result) and there are (5 + 3 + 6 + 2 + 4) total possible outcomes. The probability of drawing a grey marble is then:
5 / (5 + 3 + 6 + 2 + 4) =
5/20 =
1/4
We also know that there are 2 yellow marbles, so the probability of drawing one would be: 2 / 20 = 1/10
To find the probability of both of these events happening right after each other, multiply the probability of them each happening together.
1/4 * 1/10 = 1/40 chance of picking a grey marble and then a yellow marble.
