Answer:
65°
Step-by-step explanation:
To obtain Angle A, we use the cosine rule ;
Cos A = (b² + c² - a²) / 2bc
Cos A = (12² + 14² - 14²) / 2(12)(14)
Cos A = 144 / 336
A = Cos^-1(144/336)
A = 64.62°
A = 65°
Answer:
s=10
Step-by-step explanation:
Basically, the range rule-of-thumb is that the range is generally about four times the standard deviation.
<u>First, we find the range:</u>
Range=Maximum-Minimum
Range=100-60
Range=40
<u>Next, divide the range by 4 to get the standard deviation</u>
Range=4(Standard Deviation)
40=4(Standard Deviation)
10=Standard Deviation
Therefore, s=10, which is the standard deviation
No because there is absolutely no correlation

Answer:
The point slope form of the line would be y + 4 = 2/3(x - 8) and the equation of the line would be y = 2/3x - 28/3
Step-by-step explanation:
To find the point-slope form of the line, start with the base form of point-slope form. Then input the point we have and the slope in the appropriate places.
y - y1 = m(x - x1)
y - -4 = 2/3(x - 8)
y + 4 = 2/3(x - 8)
Now to find the slope intercept form, you simply need to solve for y.
y + 4 = 2/3(x - 8)
y + 4 = 2/3x - 16/3
y = 2/3x - 28/3
