Y = 4x - 2

Answers

Answer:

x = (1)/(4) y + (1)/(2)

Step-by-step explanation:

y = 4x - 2

first flip

4x - 2 = y

now add 2 to each side

4x + 2 = y + 2

now

4x = y + 2

divide by 4

4x / 4 = 4 + 2 / 4

so

x = (1)/(4) y + (1)/(2)

suppose 60% of kids who visit a doctor have a fever, and 20% of kids with a fever have sore throats. what's the probability that a kid who goes to the doctor has a fever and a sore throat? rounded to three decimal places as needed.

Answers

Answer:

0.12

Step-by-step explanation:

Suppose there are 100 kids

60% have fever, so what is 60% of 100?

We convert percentage to decimal and multiply:

60/100 = 0.6

0.6 * 100 = 60 have fever

20% of the people having fever (60 of them) have sore throats, so,

What is 20% of 60?

We convert percentage to decimal and multiply:

20/100 = 0.2

0.2 * 60 = 12 have sore throat

So, how many people are there with fever AND sore throat, that is 12. We took initially there to be 100 people. Hence, the probability is:

(12)/(100)=0.12
