(-0.2,1.2)
substitute 3x+2 for y and set them equal to eachother then plug in x for y
The surface area of the design is 5
Answer:
You earned an A.
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:
The top 15% of all scores have been designated As.
This means that if Z for the score has a pvalue of 1-0.15 = 0.85 or higher, the score is designated as A.
Your score is 89. Did you earn an A?
We have to find the pvalue of Z when X = 89. So
has a pvalue of 0.9525. So yes, you earned an A.
well it depends on what you are trying to do if you want to cut it in half double it or just slightly alter it
in the case of just slightly altering it it would remain 2 1/2 cups
