I believe it’s c bc if you pay attention you can see that numbers make sense
Answer:
Ameliorate retort, pertaining to preceding albeit contingent interrogate proximates subject to x = 12.
Step-by-step explanation:
Availing, exploiting, albeit maneuvering the Mathematic convention, Order of Operations (OO), the contiguous albeit proximate equation may ascertain as the preeminent imminent:
Groups: Not identified.
Exponents: Not identified, disparaging ₁.
Multiplication: Derived, pertaining to subtraction, 4 · (7/4x) = 4 · 21 <u>7x = 84</u>
Division: Derived, pertaining to multiplication, 7x = 84 ⇒ <em><u>x = 12</u></em>
Addition: Aggregate constants ⇒ 5/2x = 3/4x +21
Subtraction: Abate algebraic groups ⇒ 7/4x = 21
Answer: X = 3
Step-by-step explanation:
3(2-x)=5(2x-7)+ 2
First, distribute
6-3x = 10x -35 + 2
Now subtract and add
6+35-2= 10x-(-3x)
Which gives
39= 13x
X=3
Hope this helps!
Answer:
0.3960
Step-by-step explanation:
X - no of questions answered correct is binomial since each question is independent of the other and there are two outcomes
p = Prob of any one question right = 0.2 (1/5)
n = 44
Normal approximation would be mean = np = 8.8 and Variance = npq = 7.04
Std dev = 
X is N(8.8,2.6534)
Or Z = 
Since we approximate discrete to continuous continuity correction is to be applied
means x≥9.5
P(X≥9.5) = 0.3960
