For any function y = mx+b , m is rate of change and , b is the y intercept
]Function 1 is
y = 20x + 15,
where rate of change = 20 and y intercept = 15
And for function 2 , we can write the function as y= 10x +25
rate of change = 10 and y intercept = 25
So the statements which are true are
Function 1 has a greater rate of change than function 2.
Function 2 has a greater y-intercept than function 1.
Answer:
• Random sampling [ Probability and statistics method ]
Step-by-step explanation:
• This method is easier and saves time.
By probability, a person whose height is to be recorded will be chosen randomly. This will be done on approximately 40% members.
By statistical step, we'll feed results into distribution table. Then we'll find the mean height.

• f of n is product of frequency and respective height bracket
• n is the number of samples.
Hi there! This is simple multiplication. 3/4*1/6=3/24. 3/24 simplified is 1/8. Therefore, the answer is D) 1/8 of a pie.
