<u>coordinates of the point are (2,6) and (3,4)</u>
Answer:
Solution given:
let the given point be A(1,8) and B(4,2).
P and Q are the two points on AB such that
AP=PQ=QB=k
now
comparing AP and PB
AP=k
PB=2k
ratio of AP and PB =
= ratio 1:2
now
finding p
for this
For AB
now by using division formula
similarly
Q divides AB
Ratio of AQ and QB =
= ratio 2:1
by using division formula
Answer:
1) No
2) No
3) Yes
4)Yes
5) No
6) No
Step-by-step explanation:
In a function, no domains (x-coordinates) are repeated. Only graphs 3 and 4 meet this requirement.
Hope it helps!
2^2 = 4
just think 2 written out TWO times (hence the SECOND power).
Answer:
25.05
Step-by-step explanation:
Given that a random sample of 160 car crashes are selected and categorized by age. The results are listed below. The age distribution of drivers for the given categories is 18% for the under 26 group, 39% for the 26-45 group, 31% for the 45-65 group, and 12% for the group over 65.
<26 26-45 46-65` >65
Observed O 66 39 25 30 160
Expected E 40 40 40 40 160
Chi square
(O-E)^2/E 16.9 0.025 5.625 2.5 25.05
Thus we get chi square test statistic = 25.05
