Answer:
(1) 0.4207
(2) 0.7799
Step-by-step explanation:
Given,
Mean value,
Standard deviation,
(1) P(X ≥ 17.5) = 1 - P( X ≤ 17.5)
( By using z-score table )
= 0.4207
(2) P(14 ≤ X ≤ 18) = P(X ≤ 18) - P(X ≤ 14)
= 0.9918 - 0.2119
= 0.7799
Hey!
b is the coefficient of x, so b= -5
a is the coefficient of x^2, so a=3
c is the constant term. So c = 5
Hope it Helped☺
We know that
[volume of a cylinder]=pi*r²*h------> h=volume/[pi*r²]
diameter=4 in
r=4/2---> r=2 in
Volume =125 in³
h=125/[pi*2²]-----> h=9.95 in
the answer is
the height of the can is 9.95 in
Answer:
Step-by-step explanation:
Option A. All the real values of x where x < -1
Procedure
Solve the inequality:
(x -3)(x+1)>0
That happens in two cases.
1) When both factors >0
x-3>0 and x+1>0
x>3 and x >-1
The intersection is x >3
2) When both factors <0
x-3<0 and x+1<0
x<3 and x<-1
the intersection is x<-1.
We have obtained that the function is positive for the intervals x < -1 and x > 3. But in one of those intervals the function is decresing and in the other is increasing.
You can recognize that the function given is a parabola and, because the coefficient of the quadratic term is positive, the parabola opens upward. Then the function is decreasing in the first interval and increasing in the second interval.
