False
A arithmetic sequence is a sequence that has a difference of 2. We see that we have -17 ... and then we have 2 ... and then 21. There is NOT a difference of 2, as we can see. Therefore, yiur answer would be (false).
<u>First problem :</u>
probability to draw a red paper : 42/(42+18)=7/10
In 110 tries one can thus expect to draw 7/10*110=77 red papers
<u>Second problem :</u>
Since for 150 trials (which will give the least error) we have got 135 yellow balls, we can expect twice as much in 300=150*2 trials, which makes 270 yellow balls.
Y+2=-3/2(x-6). otherwise be equivalently.
y=3/2x -11
Ok so if The area of the square is 15 * 15. then what you need to do is subtract the total area of the 4 white sectors of a circle.
Together, the 4 sectors form one circle of radius 7.5. Now yu need to have in mind that the area of the circle they jointly form is pi * (7.5)^2. So 15 * 15 - pi * (7.5)^2 =<span>48.29

Answer: 63 mins
Step-by-step explanation:
First you got to figure out how many minutes each 1/7 is, so you devide 4 into 36 which is 9. Now that you know each 1/7 is 9 you just multiply 9•7=63
