Jillian surveyed students at her school and found out the following probabilities: \begin{aligned} &P(\text{freshman})=0.30 &P(\text{plays instrument})=0.20 &P(\text{freshman and instrument})=0.10 \end{aligned}


P(freshman)=0.30
P(plays instrument)=0.20
P(freshman and instrument)=0.10


Find the probability that a student plays an instrument given they are a freshman.

Step-by-step explanation:

Use conditional probability.

P(A given B) = P(A and B) / P(B)

P(instrument given freshman) = P(instrument and freshman) / P(freshman)

P(instrument given freshman) = 0.10 / 0.30

P(instrument given freshman) = 0.33

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

hope it
