Check the picture below.

now, since we know what "f" is, let us use the CNT triangle with the small COR one.

$\bf \cfrac{36+f+30}{36}=\cfrac{48+32+g}{48}\implies \cfrac{36+24+30}{36}=\cfrac{48+32+g}{48} \\\\\\ \cfrac{90}{36}=\cfrac{80+g}{48}\implies \cfrac{5}{2}=\cfrac{80+g}{48}\implies 240=160+2g \\\\\\ 80=2g\implies \cfrac{80}{2}=g\implies 40=g$

Answer:

52.63% probability that thids intial repair was made by the first technican

Step-by-step explanation:

Bayes Theorem:

Two events, A and B.

$P(B|A) = \frac{P(B)*P(A|B)}{P(A)}$

In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.

In this question:

Event A: Incomplete repair

Event B: Made by the first technican.

The first technican, who services 40% of the breakdowns, has 5% chance of making incomplete repair.

This means that $P(B) = 0.4, P(A|B) = 0.05$ .

Probability of an incomplete repair:

5% of 40%(first technican) or 3% of 60%(second technican). So

$P(A) = 0.05*0.4 + 0.03*0.6 = 0.038$

Given that there is a problem with the production line due to an incomplete repair, what is the probability that thids intial repair was made by the first technican

$P(B|A) = \frac{0.4*0.05}{0.038} = 0.5263$

52.63% probability that thids intial repair was made by the first technican

We have to find the percentage ratio of two numbers. It is $\frac{36}{400}*100 = 9%$ . And the correct answer is D).

Alternatively, by setting up a ratio, we can write that If
400_____100%
36_____x
And x=9%

Answer:

3y² / x⁴z⁶

Step-by-step explanation:

12xy³z⁶ / 4x⁵yz¹² = 12/4 * x/x⁵ * y³/y * z⁶/z¹²

= 3 * 1/x⁴ * y² * 1/z⁶

= 3y² / x⁴z⁶
