What is the equation of a line that passes through 4-7 and perpendicular to y=2/5 it equals 75p
Answer:
R = 0.862
Strong positive relationship
Step-by-step explanation:
Given the data:
Test Chemistry Student Score,
x Grade, y
1 2 3 4 5 6 7 8 9 10 11 12
Score,x = 65 50 55 65 55 70 65 70 55 70 50 55
Grade, y = 85 74 76 90 85 87 94 98 81 91 76 74
Using technology :
The CORREL function in excel, calculators will give accurate value of the correlation Coefficient between two variables, x and y. The correlation Coefficient obtained using technology is : 0.862
The correlation Coefficient value ranges between (-1 and 1) with values closer to either - 1 or 1 reflecting stronger relationship. A value of 0 means there is no relationship between the variables. Negative values indicate negative relationships while positive indicates positive association between the variables.
Therefore. With a correlation Coefficient of 0.862, the correlation Coefficient can be interpreted as meaning that ; there is a strong positive relationship between score and grade.
Answer:
About 316.13
Step-by-step explanation:
We know:
Diameter (d) = <u>11</u> (of the circle)
Area of the circle: pi(11)^2 = <u>121pi </u>
Side of the square = <u>8 </u>
so area of the square is 8^2 = <u>64</u>
Area of the shaded region:
121pi-64 =316.13
