Happy Pride Month!
Part 1:
You can solve the pair of equation graphically by writing the y-intercepts which are (0,-1) and (0,-5) Then follow the slopes of each line till the intercept. The slopes are up 2 over 1 and up 4 over 1 respectivily
Part 2:
When you graph these you get the answer of (2,3)
x is 2 and y is 3
Have a good day!
Si son 35 integrantes, el número se obtiene multiplicando 5 por 7.
Si los equipos tienen el máximo número de corredores, cada uno tendrá 7 corredores. Por lo que habrá 5 equipos.
Step-by-step explanation:
the expected value is calculated by multiplying each of the possible outcomes by their probability, and then summing up all these results.
tossing a coin 2 times gives us 4 possible different outcomes (all with the same probability of 0.25) :
head - tail
head - head
tail - head
tail - tail
to have exactly one head is 2 out of these 4 possible outcomes, and the probability is 0.5.
everything else is also 2 out of these 4 possible outcomes, and the probability for that is therefore 0.5 too.
the expected value (from your point of view) is
9×0.5 - 15×0.5 = -$3.00
You must divide 2400 by 4 to find your answer. If you know 24/4, then it should be easy. 24 divided by 4 is 6, so add those 2 zeros and you should get 600 pennies for each student.
