Answer:
0.125
Step-by-step explanation:
<u>Smaller Wheel</u>
Total Number of Equal Sectors = 8
The number of Red sectors =3
The probability of obtaining red on the smaller wheel 
<u>Larger Wheel</u>
Total Number of Equal Sectors = 12
The number of Red sectors =4
The probability of obtaining red on the larger wheel 
Assuming that the wheels are independent and each outcome is equally likely, the probability that we get red on both wheels
The probability is: 0.125
Can you help me please I need help with a couple of questions
The domain is all the positive values and the range is also all the positive values.
Then the answer is the option D) s>0 and V(s) > 0.
Answer:
Step-by-step explanation
- Let x be the number of adults and y the number of kids
We can then write this two equations :
x+y= 33
15x+7y= 311
- let's solve the two eaquations
to do that we should combine them both in a way that help us get rid of one of the variables.
Let's multiply the first equation by -7 to get rid of y by adding it to thr second equation
-7x-7y= -231
now add both equations .
15x+7y-7x-7y=311-231
we get : 8x = 80
as you notice y is gone and we get a classic easy equation to solve
x= 80/8
= 10
so the number of adults is 10
let's go back to the first equation ( x+y= 33) and replace x with 10
10+y= 33
y= 33-10
=23
let's check using the second equation :
(10*15)+(23*7) = 311
that is true
so :
- the number of adults is 10
- the number of kids is 23
47/5=9.40
9*5=45
47/5= 9 2/5
