Samantha and Luis are attempting to dentermine the average number of library books that seventh-grade students check out at one time. Samantha surveys every other seventh grade students
Answers
Answer: Your question is incomplete
But if the attached image is the complete question “whose sample is the most random”, then your answer is:
Luis’ sample.
Step-by-step explanation:
A random sample is one where each member is selected at random.
It is the kind of sampling where each member has an equal chance of being selected.
Samantha and Luis are trying to determine the number of library books that seventh graders check out. Their focus is;
1.) Seventh graders and
2.) Library books
Samantha surveys seventh graders leaving the library while Luis surveys seventh graders at random in the school cafeteria.
Samantha’s survey is more focused because each member of her sample was leaving the library meaning that they had handled books.
But Luis’ sample is more random because he takes his survey from all seventh graders (seventh graders in the cafeteria). With his random sampling, there is a high probability that each member never handled library books.

Find the area of the triangle.
Answers
Answer: 6 units squared
Step-by-step explanation: ok here is how you do it so you make the triangle like I did and once you make it. You count the squares about how long it is and how high it is in this case I got for the base 6 and the height 2 so we multiply to get 12 also we divide 12 and 2 to get 6 units squared there you go. hope this helps.
PT=y,TR=x+3,QT=2y,TS=3x-1 I'm confused and u really need help. My teacher isn't the greatest and wasn't much help.
Answers
Answer:
y=10, x=7
Step-by-step explanation:
Since the diagonals of a parallelogram bisect each other, PT should be equal to TR and QT should be equal to TS. So, y=x+3 and 2y=3x-1. Multiplying the first equation by 3 gives you 3y=3x+9. Using elimination to subtract these two equations gives you y=10. And since y=x+3, substitute y=10 there. 10=x+3, x=7.

5. (5 points) You have a jar full of jelly beans. You will randomly pick 2 jelly beans without replacement.The probability that you choose 2 green jelly beans is 14/95 and the probability of drawing one green jelly been is 2/5 . what is the probability of picking a second green, given the first was green?
Answers
Answer:
7/19
Step-by-step explanation:
In order to find the probability that two events happen in a sequence you simply have to multiply the probability of each individual event together. Since the probability of the sequence is given to us as well as the probability of drawing the first green jelly bean, this means we need to divide the first probability by the probability of the sequence to get the probability of the second event. Basically, reversing the process. Dividing two fractions, we simply divide the numerators by each other and then the denominators by one another.
[tex]\frac{14 / 2}{95 / 5} = \frac{7}{19}[/tex]
Therefore, the probability of picking the second green jelly bean is 7/19

How many more miles does he have to drive?
Answers
Answer:
442
Step-by-step explanation:
625-183=442
The more miles he have to drive is 442miles.
We have given that,Jon is taking a 625 mile trip.On the first day, he drove 183 miles.
We have to find the how many more miles does he have to drive.
What is the formula for the total miles drive?Total distace mile drove =mile drove first day+Remaining drove in miles
So we can write it as,
Total distance miles-Miles drove first day= Remaining miles
Total distance=625
first day distance=183
Remaining distance
=625-183
=442
Therefore the remaining distance is 442miles.

A toy company uses the box shown below to package wooden cubes. Each wooden cube has a volume of 1 8cubic foot. In total, how many wooden cubes will fit in the box.
Answers
Answer:
240 cubes
Step-by-step explanation:
A toy company uses the Box shown below to package wooden cubes each wooden Cube has a volume of 1/8 cubic feet in total how many wooden cubes will fit in the Box
Volume of the box = length × width × height
= 5 ft × 3 ft × 2 ft
= 30 ft³
Volume of wooden cube = 1/8 ft³
how many wooden cubes will fit in the box.
Number of wooden cubes that will fit in the box = volume of the box ÷ volume of the wooden cube
= 30 ft³ ÷ 1/8 ft³
= 30 × 8/1
= 240 cubes
Number of wooden cubes that will fit in the box = 240 cubes
