To build a school;
20 workers -> 18 days.
So 1 worker -> 18/20 days.
So; 12 workers -> (12×18)/20 days.
-> (12×9)/10 days
->10.8 days.
so 10.8 days is your answer.
Hope it helps...

<span>The answer is letter C - 0.33.
The conditional probability formula for the probability of A given B is
P(A l B) = P (A and B) over P (B)
In this case, it's
P (worms l shrimp) = </span>P (worms and shrimp) over P (shrimp)
P (worms l shrimp) = P (0.2) over P (0.2 + 0.4)
P (worms l shrimp) = P (0.2) over P (0.6)
P (worms l shrimp) = 0.33
Answer:
54
Step-by-step explanation: 36 * 6 = 216
216 divided by 4 = 54
Answer:
The all solution of given trigonometrical equation is + 2πn .
Step-by-step explanation:
Given trigonometrical equation as :
7 - 14 sin x + 2 = - 5
Now, Rearranging the equation
7 - 14 sin x + 2 + 5 = 0
Or, 7 - 14 sin x + 7 = 0.
Taking 7 as common
So, - 2 sin x + 1 = 0.
∵The standard form of quadratic equation
a x² + b x + c = 0
So, breaking the mid term we get
- sin x - sin x + 1 = 0.
Or, sin x (sin x - 1) - 1 (sin x - 1) = 0
Or, (sin x - 1) (sin x - 1) = 0
Or, (sin x -1) = 0 and (sin x - 1) = 0
So, sin x = 1
∴ x =
i.e x = 90°
Or, ∠x =
And for all solution + 2πn , where n∈ 0 to ....
Hence, The all solution of given trigonometrical equation is + 2πn . Answer
