Question #55

1 answer:

7 0

Lets make a proportion with the information we know. For every 1000, 8 of tax is paid.

8/1000

Then, use the rest of the information to make another proportion. We don’t know how much the tax is, so let’s call it x.

x/150000

Set the equations equal to each other

8/1000=x/150000

Cross multiply

1000x=1200000

Divide by 1000 on both sides

x=1200

According to the Stack Overflow Developers Survey of 20184, 25.8% of developers are students.The probability that a developer is

murzikaleks [220]

Answer:

0.0326 = 3.26% probability that she is a student.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

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

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Woman developer

Event B: Student

Probability that the developer is a woman:

7.4% of 25.8%(students).

76.4% of 100 - 25.8 = 74.2%(not students). So

$P(A) = 0.074*0.258 + 0.764*0.742 = 0.58598$

Student and woman developer.

7.4% of 25.8%(students), so

$P(A \cap B) = 0.074*0.258 = 0.019092$

If we encounter a woman developer, what is the probability that she is a student

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.019092}{0.58598} = 0.0326$

0.0326 = 3.26% probability that she is a student.

Henry combines 7.49 litters of red paint with 6.26 litters of red paint and pours it in to 4 container with 0.43 litters of pain

11111nata11111 [884]

To find the answer we start by adding the contents of both containers together
7.49 + 6.26 = 13.75
Since we know that there is leftover paint we are going to subtract the leftovers from the total of combined paint
13.75 - 0.43 = 13.32
The combined paint is poured into 4 containers so we divide our combined total minus the leftovers by 4
13.32/4 = 3.33
Answer: There are 3.33 liters of paint in each container
