A spinner is divided into five sections, labeled A, B, C, D, and E. Devon spins the spinner 50 times and records the results in
the table.
Based on the table above, make a prediction for 200 trials.
Choose how you will answer this question below. Then, answer the question.
How many times will the pointer land on a vowel? (The vowels in this table are A and E.) Answer in complete sentences. Be sure to explain how you found your answer. Include calculations if necessary.

The correlation coefficient tells that every increase in sea surface temperature of one degree Celsius will result in an average of 0.1578 fewer centimeters of coral growth per year.
Using technology
The mean= x bar = 26.4667
The mean = y bar= 0.86
The standard deviation= Sx= 0.2251
The standard Deviation Sy= 0.0438
The Correlation Coefficient= r = -0.8111
The slope= b= r* Sy/Sx= -0.15789
The intercept is 5.0389
(d)<u><em> Every increase </em></u>in sea <u><em>surface temperature</em></u> of one degree Celsius will result in an average of <em><u>0.1578 fewer</u></em> centimeters of <em><u>coral growth</u></em> per year.
Here the independent variable is X the sea surface temperature and dependent variable is the Y coral growth.
As the temperature decreases which is along x- axis the growth increases along y axis.
From the given options the option d is the best answer according to the question given.
The same values are calculated using different technology .
