Answer:
for 5 people = 4 potatoes
remaining people = 13-5 =8
3 p0tatoes for four people
so 6 potatoes for 8 pe0ple
total potatoes used = 6+4 = 10

vertical translation) y=f(x)+k
horizontal translation) y=f(x-h)
horizontal translations flip the sign*
You traveled 11 miles because if you did use 28.00 and $1.50 then you take that answer and then add the $4.00 and $3.00 you will get $7 so you just subtract that for the other number and you get 11 miles because it is $1.50 per mile
Part 1 : Marlow wants to know how many students in his school enjoy watching the TV news. He asks all 27 students in his art class and finds that 30% of his classmates enjoy watching the TV news. He claims that 30% of the school's student population would be expected to enjoy watching the TV news. Is Marlow making a valid inference about his population?
No, it is not a valid inference because he asked all 27 students in his art class instead of taking a sample from the school
No, it is not a valid inference because his classmates do not make up a random sample of the students in the school
Yes, it is a valid inference because he asked all 27 students in his art class
Yes, it is a valid inference because his classmates make up a random sample of the students in the school
Answer = The correct answer is <span>B because Marlow was supposed to ask random kids and they were not suppose to be in his class.
Part 2 : </span><span>Carl takes a random sample of 100 students in his school and finds that 72% of the sample prefers pizza over burgers. There are 1,500 students in the school. Based on the sample proportion, how many students in the school would be expected to prefer pizza over burgers? </span>
72
100
1,080
<span>1,500
</span>
<span>1500 / 100</span>×72<span>= 1080</span><span>
