Answer:

Solution given:

we have

m<PTQ=m<RTS

x+20=3x+12.

20-12=3x-x

$\frac{8}{2}$

now

16.m<PTQ=x+20=4+20=24°

17.

again

m<PTR+m<PTQ=180°[supplementary]

m<PTR=180°-24°=156° is your answer

Mekhanik [1.2K]

Answer: Yes, it will be enough.

Step-by-step explanation:

I will answer this in English:

We have 27 students and 81 units, we want to give 3 units to each student.

This is only possible if the quotient betwen 81 and 3 must be bigger than 27.

Lets do it:

81/3 = 27

So we have exactly enough for the 27 students.

Answer:

There is a 90.32% probability that the cake was baked by Doug.

Step-by-step explanation:

We have these following probabilities:

A 70% probability that Doug bakes the cake.

A 30% probability that Jeremy bakes the cake.

A 40% probability that a cake baked by Doug gets a thumbs up.

A 10% that a cake baked by Jeremy gets a thumbs up.

One cake was selected at random on 10/01/2014 and got a "thumbs up".

1. Find the probability that the cake was baked by Doug.

The probability that a baked cake gets a thumbs up is:

$P = 0.7*0.4 + 0.3*0.10 = 0.31$

Of those, 0.7*0.4 = 0.28 are baked by Doug.

So the probability is:

$P = \frac{0.28}{0.31} = 0.9032$

There is a 90.32% probability that the cake was baked by Doug.
