Answer:10/16 (can simplify I think)
Step-by-step explanation: First you do 10+6 to find out the total of all the marbles which is 16. There are 10 blacks so you do 10/16 AS you wanna find out the probability of getting the black.
Answer:
No , the cause and effect can be finished up through analyses as it were.
What we have in the inquiry is only an observational investigation where we basically study 3000 grown-ups and attempt to outline the outcomes with no trial proof.
Imagine a scenario in which individuals who had breakfast normally were inclined to maintain their weight reduction, for sure if individuals who keep up weight reduction will in general have breakfast routinely.
henceforth the circumstances and logical results relationship cannot be built up
So as to do so , one must lead measurable trials, for example, autonomous example t test or ANOVA examination
Answer:
e. 0.977
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:

Which of the following is closest to the proportion of daily transactions greater than 350?
This is 1 subtracted by the pvalue of Z when X = 350. So



has a pvalue of 0.023
1 - 0.023 = 0.977
So the correct answer is:
e. 0.977
<span>-7x + 2y = 0
6x + 6y = 0
</span><span>ordered pair: (−2,2)
the way to figure out if that ordered pair is a solution is pretty simple, you just plug the ordered pair into both equations, and check if the outcome is true.
</span>-7(-2) + 2(2) = 0
14 + 4 = 0
18 = 0 is NOT true, so this isn't a solution. still, check your second equation as well.
6x + 6y = 0
6(-2) + 6(2) = 0
-12 + 12 = 0
for this equation, it is a solution. however, because the solution must apply to the system as a whole, and not just one of the equations, the ordered pair still is not a solution.
