4. 20 : 24 ratio that the ball picked wont be green
5. false
11. 15
12. half a chance (1/2)
13. 51
16. 9.79 × 10^-5
17. 4y = 29
18. b) 6.1
19. 80
20. x = -8/7
30. Area ≈ 7982.79
34. check the picture i attached for the histogram
THIS TOOK SO LONG
Yo sup??
Let the length of river D be x
then the lenght of river C will be 200+x
but,
lenght of river C+lenght of river D=5580
x+x+200=5580
2x=5380
x=2690
Therefore lenght of river D is 2690 and that of C is 2890
Hope this helps
Answer:
Step-by-step explanation:
Given that a survey showed that 72% of adults need correction (eyeglasses, contacts, surgery, etc.) for their eyesight
X - number of people who need correction for their eyesight
X is binomial since each event is independent and there are only two outcmes.
X (18, 0.72)
Required probability = the probability that no more than 1 of them need correction for their eyesight.
=P(X=0)+P(X=1)=0.00000296+0.000137
=0.00014
Yes 1 is a significantly low number as probability is almost zero.
96 is the result 200 x .48
We can use the points (1, 4) and (4, 9) to solve.
Slope formula: y2-y1/x2-x1
= 9-4/4-1
= 5/3 or 1 2/3
Best of Luck!
