Answer:
all 0.5
Step-by-step explanation:
Suppose this is a fair coin, so the chance of getting head vs tail is 50-50, or 0.5.
If you flip a coin, the chance of getting head is 0.5
If you flip a coin the 2nd time, this event is independent and unrelated to the previous result, hence the chance of getting head is still 0.5
If you flip a coin 25 times and all get head, then the chance of getting the next head is still 0.5. Because this event is still independent and not related to all the previous flips.
Por medio de sistema de ecuaciones:
*adultos (a) = $400
*niños (b) = $150
total de entradas : a + b = 600 ecua 1
dinero recaudado:
400a + 150b = 196 250 ecua 2
operamos:
a + b = 600 ecua 1
400a + 150b = 196 250 ecua 2
--------------------------
(-150) a + b = 600
400a + 150b = 196 250
-----------------------
- 150a - 150b = -90 000
400a + 150b = 196 250
-----------------------
250a = 106 250
a = 106 250/250
a = 425 adultos
a + b = 600
425+b =600
b = 600-425
b = 175 niños
comprobacion:
400a + 150b = 196 250
400(425)+150(175)=196 250
170 000 + 26 250 = 196 250
196 250 = 196 250

Step-by-step explanation:
b is clearly negative
- - = +
so therefore, subtracting the negative will result in a larger answer than adding a small positive to a negative
I'm sorry, but the spinner that you choose does matter in this case.
For spinner A, there are 5 equal sections with a 1 being in only one of them as well. This gives you a
chance of landing on the number 1.
For spinner B, there are 6 equal sections with a 1 being in only one of them. This gives you a
chance of landing on the number 1 - a worse chance than if you were to use spinner A.
So for this question,
you have a better chance of landing on number 1 if you choose to use spinner A.
Use the fact that 1 hour = 60 minutes, from which you can create your conversion factor: 1 = hour / 60 minutes. That permit you to multiply the number of miles per hour times [1 hour/60minutes] to convert 50 miles per hours to miles per minute. This is the calculation: 50 miles/hour * [1hour/60minures] = 0.833 miles / minute
