[10+10 points] 5) there are 12 students in my class - 10 males and 2 females. a. if i pick a team of 5 students randomly to answer a difficult question, what is the probability that there is at least 1 female in my team? b. i have 1 difficult question per lecture. if i pick a student randomly to answer this difficult question in every lecture, what is the probability that i will pick a female at least once in my next 5 lectures? a student previously picked can be picked again.

step-by-step explanation:

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
