3x+3x-5= 1
6x-5=1
Whenever moving a number, the sign always changes.
6x-5+5= 1+5
6x= 1+5
6x= 6
divide both sides by 6
6x/6= 6/6
x= 1
Check solution by using the substitution method
3(1)+3(1)-5=1
3+3-5=1
6-5= 1
1=1
Answer: x=1
Answer:
(f+g)(x) = 4 x^2 + (3/2) x - 7
Answer (c) on your list
Step-by-step explanation:
f+g (x) = f(x) + g(x) = x/2 - 3 + 4 x^2 + x - 4
combine the terms in "x" = x/2 + x = (3/2)x
combine the numerical terms: - 3 - 4 = - 7
Then the final expression is:
(f+g)(x) = 4 x^2 + (3/2) x - 7
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
