Find the slope given the two points
TEA [102]

Answer:

15. -2  16. 0  17. undefined

Step-by-step explanation:

Slope of two points can be calculated by (y change) / (x change).

(y1 - y2) / (x1 - x2)

15)  (1-5) / (4-2) = -2

16)  (6-6) / (1-10) = 0 since y change is 0.

17) (-5-3) / (4-4) = undefined since x change is 0 but you cannot devide by 0.

calculate the means and the standard deviation of the following set of data 4.578g, 4.581g, 4.572g, 4.573g, 4.601g, 4.577g. stat
AfilCa [17]

Answer:

68% Confidence interval  = [4.5752, 4.5848]

95% Confidence interval  = [4.5688, 4.5918]

Step-by-step explanation:

Sample mean (X) = 4.580

Sample Standard Deviation (S) = 0.01065

Sample size (n) = 6

T_{(5)} for alpha/2 0.84 = 1.1037

T_{(5)} for alpha/2 0.975 = 2.5706

68% Confidence interval = [x-T_{(5)}\frac{S}{\sqrt{n}}, x+T_{(5)]\frac{S}{\sqrt{n}}] = [4.5752, 4.5848]

95% Confidence interval = [x-T_{(5)}\frac{S}{\sqrt{n}}, x+T_{(5)}\frac{S}{\sqrt{n}}] = [4.5688, 4.5918]
