Kendall asked 40 randomly-selected seniors at his high school about their plans for after they graduated. Twenty-nine students said they planned to go to college. If there are 380 seniors at Kendall’s high school, estimate the number who plan to go to college.
There are diffrent versions of this test so without the actually questions u dont know if the list of response are correct for ur version
A. 245
B. 275*
C. 310
D. 330
29/40 = 0.725
0.725 * 380 = ?
You're welcome, Miae.
Be sure you look at your other problem above.

19. again, use Nobody's hints
i hope this helped, my fellow cheaters! <3
guys we've talked about this! The letters wont always have the same answer associated to them! ESPECIALLY not on tests and unit tests!
Right is wrong, all test answers are randomized and in different orders!
Thank you Ms.Sue
Im so confuzled
theres 29 questions for meeeeeeeeee
I got a 13/17 with my own answers but for the Multiple choice these were the correct ones.
1 14
2 750
3 The data is not valid because bird watchers are more likely to visit a bird refuge.
4 A double line graph
5 8
6 Sandy Ridge 14, Autumn care 12.
7 Which subject is your favorite, math which is easy or English which is difficult.

Who's right
Kendall asked 40 randomly-selected seniors at his high school about their plans for after they graduated. Twenty-nine students said they planned to go to college. If there are 380 seniors at Kendall’s high school, estimate the number who plan to go to college.
29/40 is the fraction of seniors who plan to go to college. We can use this information along with the total number of seniors to estimate the number who plan to go to college.
29/40 is equivalent to 0.725 when expressed as a decimal.
So, the estimated number of seniors who plan to go to college is:
0.725 x 380 = 275
Therefore, an estimate of 275 seniors plan to go to college.
A researcher tagged 40 giant turtles in 2008. In 2009, she returned and captured 50 turtles, 16 of which were tagged. In 2010, she returned again and captured 30 turtles, 8 of which were tagged.
Use a proportion to estimate the turtle population for 2009.
Use a proportion to estimate the turtle population for 2010.
To estimate the turtle population for 2009, we can set up a proportion:
Number of tagged turtles in 2009 / Total number of turtles caught in 2009 = Number of tagged turtles in 2008 / Total number of turtles in 2008
Simplifying, we get:
16 / 50 = 40 / x
where x is the estimated turtle population in 2008.
To solve for x, we can cross-multiply and simplify:
16x = 50 * 40
16x = 2000
x = 125
Therefore, an estimated 125 giant turtles were in the population in 2008.
To estimate the turtle population for 2010, we can set up a similar proportion:
Number of tagged turtles in 2010 / Total number of turtles caught in 2010 = Number of tagged turtles in 2008 / Total number of turtles in 2008
Simplifying, we get:
8 / 30 = 40 / x
where x is the estimated turtle population in 2008.
To solve for x, we can cross-multiply and simplify:
8x = 30 * 40
8x = 1200
x = 150
Therefore, an estimated 150 giant turtles were in the population in 2008.
i got 10/17
Is Weeb Right?
Guys dont trust Right. I used his answers and it got me 11/17. I mean it's not bad but could be better. Here are the regular answers: B, C, C, A, D, D, D, D, A, C, B, C, B, A, B, C, B. can't help for the other 5 questions.
