Me your student government association decide to do a fundraiser to raise money for a field trip they d ecide to sell t shirts and sweatshirts. the profit for each t shirts is $10 and the profit for each sweatshirt is $15. they want to sell 50 items at most compared to t shirts they want to sell at least half as many swaetshort with profit of at least $500.
graph the system of inequalities

Step-by-step explanation:

They certainly have 50 items. The overall profit should be at least $500 (?)

If they would sell only t-shirts , the overall profit would be no more then $500

If they would sell only sweatshirts, the overall profit would be at least $750

Considering x- number of t-shirts sold and y- number of sweatshirts sold then:

step-by-step explanation:

most likely the answer is a.

alice wins if a total of 5 is rolled. finn wins if a total of 9 is rolled.

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
