Step-by-step explanation:
there are 50 students and 5 prizes (1 + 1 + 3).
so, already in natural language we would say "there is 1 prize for every 10 students".
formally, remember the rule of probability : desired outcomes over total possible outcomes.
this is here
5/50 = 1/10 = 0.1
your can see it also this way :
if there was only 1 prize, each student would have a chance of 1/50 of winning.
now there are 5 prizes, which gives everybody 5 times the chance of winning. which is then 5×1/50 = 5/50 = 0.1
Answer:
C is da answer
Step-by-step explanation:
Answer:
X= -3;
Y=78
Step-by-step explanation:
A: X+Y=75
B: 10X+Y=48
B-A: (10X+Y)-(X+Y)=48-75
10X+Y-X-Y= - 27
9X=-27
X= -3;
Now
A is : -3+Y=75
Y=75+3=78
Answer:
the area of the game room would be 15 yards by 10 yards
Step-by-step explanation:
you multiply the number of feet by 5
the five being the number of yards that are in a foot
To shift a graph down by two units, -2 must beg added to the function.
Since g(x)=0.5x-k already, k=2, because it is already specified that the constant will be subtracted.
