Answer:
what
Step-by-step explanation:
Answer:
P [ K > 3.95] = 0.5633
Step-by-step explanation:
The interpretation of the given question goes thus;
Suppose that K is a random variable
P[-3.95 ≤ K ≤ 3.95] = 0.725
where; P [ + 3.95 < K ] = P [K < - 3.95]
P[K< 3.95] - P [K > - 3.95] =0.725
P [K < 3.95] - [ 1- P[K < 3.95]] = 0.725
P[k < 3.95] - 1 + P [ K < 3.95] = 0.725
3.95 P [ K < 3.95] -1 = 0.725
3.95 P [ K < 3.95] = 1.725
P [ K < 3.95] = 1.725/3.95
P [ K < 3.95] = 0.4367
P [ K > 3.95] = 1 - P[K< 3.95]
P [ K > 3.95] = 1 - 0.4367
P [ K > 3.95] = 0.5633
Answer:
g(x)=x2−x−6g(x)=x2-x-6
Set x2−x−6x2-x-6 equal to 00.
x2−x−6=0x2-x-6=0
Solve for xx.
Tap for fewer steps...
Factor x2−x−6x2-x-6 using the AC method.
Tap for more steps...
(x−3)(x+2)=0(x-3)(x+2)=0
If any individual factor on the left side of the equation is equal to 00, the entire expression will be equal to 00.
x−3=0x-3=0
x+2=0x+2=0
Set x−3x-3 equal to 00 and solve for xx.
Tap for more steps...
x=3x=3
Set x+2x+2 equal to 00 and solve for xx.
Tap for more steps...
x=−2x=-2
The final solution is all the values that make (x−3)(x+2)=0(x-3)(x+2)=0 true.
x=3,−2
A. 2x + 1 (2x is the "twice a number")
b. x - 6 (x is the number being decreased)
c. 2/3x
