Hold on give me a second i got this
Answer:
251 b + 21 or b = (-21)/251
Step-by-step explanation:
Simplify the following:
6 b - 7 (-35 b - 3)
-7 (-35 b - 3) = 245 b + 21:
245 b + 21 + 6 b
Grouping like terms, 245 b + 6 b + 21 = (6 b + 245 b) + 21:
(6 b + 245 b) + 21
6 b + 245 b = 251 b:
Answer: 251 b + 21
__________________________________________
Or if you need the Roots.
Solve for b:
251 b + 21 = 0
Subtract 21 from both sides:
251 b + (21 - 21) = -21
21 - 21 = 0:
251 b = -21
Divide both sides by 251:
Answer: b = (-21)/251
You can think of it as two separate fractions. 1/2 divided by 3/1. You can solve this by multiplying the first fraction by the reciprocal of the second fraction. A reciprocal is switching the fraction by turning it over. So you just have to solve 1/2 multiplied by 1/3. As a result you get 1/6 as the answer! Hope this helped!
Answer:
P(n) = 0.5
Step-by-step explanation:
For two events which are independent, we use the multiplication rule which states P (A and B) = P(A) * P(B). Substitute P(m) = 0.4 and P(m and n) = 0.2 into this formula.
P (m and n) = P(m) * P(n)
0.2 = 0.4*P(n)
Divide by 0.4 on both sides.
0.2 / 0.4 = P(n)
0.5 = P(n)
