Ok this is a linear equation that is descending and is in slope intercept form
Answer:
a) From the chart crated with Microsoft Excel, we have that the correlation coefficient, r = √0.8581 ≈ 0.93 to the nearest hundredth
The steps used includes
1) Inputting the given data into the cells on a Microsoft Excel spread sheet
2) Highlighting and sorting the data in the cells in order of increasing Rainfall
3) Generating a dot plot using the sorted data from above
4) Adding the trend line, Square of the linear regression, and the trend line equation
5) Adding the axis labels
(b) The correlation coefficient states that there is a strong positive correlation between the monthly rainfall and and Umbrella sales
Step-by-step explanation:
Answer:
c = -2
Step-by-step explanation:
Given equation is :
4(3+c)+c=c+4
12 + 4c + c = c + 4
12 + 4c = 4 [dividing by 4]
3 + c = 1 [adding and subtracting 3]
c = -2
Answer: Not enough information
Step-by-step explanation:
We need to know the measure of angle AED, but there is no way to find it, so therefore there is not enough information.
So basically what this is trying to tell you is are they mutiples / equal to each other, also a rule. Its A. because 25 x 2 = 50, then 50 x 2 = 100 and so on.
So the answer is A
Hope it helps! :D
