Answer:
no sorry but which type of qurestion it is
Step-by-step explanation:
let equation be y = mx + b.
m = (9- (-3))/(-4 - 2) = -2
sub (2, -3):
-3 = -2(2) + b
b = 1
therefore equation of the line is y = -2x + 1

Answer:
P = -6.4
Step-by-step explanation:
Solve for P:
P + 0.4 = -6
Subtract 0.4` from both sides:
P + (0.4 - 0.4) = -0.4 - 6
0.4 - 0.4 = 0:
P = -0.4 - 6
-0.4 - 6 = -6.4:
Answer: P = -6.4
The line BC in the figure above is the AXIS of the cylinder.
Axis of the cylinder is the line formed by the centers of the bases of a cylinder.
Answer:
(20.322 ; 23.678)
Step-by-step explanation:
Given that :
ΣΧ = 242 ; ΣΧ2 = 5,413 ; N = 11
Mean, m = ΣΧ / N = 242 / 11 = 22
Standard deviation = sqrt[(ΣΧ2/N) - (ΣΧ/N)²]
Standard deviation = sqrt[(5413/11) - (242/11)^2]
Standard deviation = sqrt(8.0909090) = 2.84
Confidence interval = m ± Zcritical * s/sqrt(n)
Zcritical at 95% = 1.96
Lower boundary = 22 - 1.96*2.84/sqrt(11)
Lower boundary = 22 - (1.96 * 0.8562922) = 20.322
Upper boundary = 22 + (1.96 * 0.8562922) = 23.678
