Number of students = 26
Number of students without siblings = 4
⇒ Number of students with at least one siblings = 26 - 4 = 22
Number of students with brothers = 17
Number of students with sisters = 7
⇒ Number of students with both a brother and a sister = 17 + 7 - 22 = 2
P(student has a brother, given that they have a sister) = 2/7

We can gather from what's given that y=20xy represents the total number of bottles produced in the given time in seconds, which is x. When x=1, y=20, This means that each second the machine can make 20 soda bottles. Each minute is 60 seconds, so when x=60, y=20*60 =1200 soda bottles.
Answer:
The 7 digit in 873,240 is 1000 times greater than the 7 digit in 17,498.
Step-by-step explanation:
Okay so first off first off I believe 4-6 is linear because it is increasing at a steady rate and 7 is exponential because it has a constant rate of growth. I’m not 100% I’m correct on that. 8 is linear, 9 is exponential.
For 4: f(x)=-1/2x + 1
5: f(x)=-2x +4
That’s all I know right now. I hope it helps a little bit
