So this question is just a comparison problem.
If you split a chocolate bar into seven pieces, and ate 5 of them, you would have eaten less than if it were split into 10 pieces and you ate 8.
Another way to see this is if we did it mathematically.
5/7*10/10 = 50/70
8/10*7/7 = 56/70
Now that the denominators are the same, you can compare 50 to 56 and obviously, 50 is smaller than 56.
Hope this helps! If you have any questions, just ask!
Answer:
And we can find this probability on this way:
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problm
Let X the random variable that represent the scores on an exam of a population, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability on this way:
Answer:
its each section represents $30. celia originally had $150 in her account
Step-by-step explanation:
there are 3 sections on the bar there are 45 she had 10 sections which is why the answer is this
hope this helps
Answer:
I would say that it's y = -4
Step-by-step explanation:
Because if you're shifting to the left you are decreasing.
If you were to move left on a graph you'd be going towards the negative side.
