The figure shows two intersecting chord, thus this simply can be solved using the Intersecting Chord Theorem, which states that "<span>When two chords intersect each other inside a circle, the products of their segments are equal."
Thus,
(15mx2m=5mxn)
n=6m</span>
Answer:
Step-by-step explanation:
The given information can be tabulated as follows.
Success type High Moderate Low Total
0.40 0.35 0.25 1
Good reviews 0.95 0.60 0.10
Combined prob 0.4*0.95 0.35*0.6 0.25*0.1
0.38 0.21 0.025 0.6125
A) the probability that a product attains a good review
=Prob it it successful and gets good review + Prob it is moderate successful and gets good review +Prob it it low successful and gets good review
= 0.6125
B) If a new design attains a good review, the probability that it will be a highly successful product= 
C) Prob that does not attain a good review =(0.40*0.05)+0.35(0.4) +(0.25)*0.9
= 0.385
Prob for successful not getting good review = 0.40(0.05) = 0.02
Reqd prob = 
Given that <span>cos a = 3/5 and it is in the first quadrant :
then:
a=arccos 3/5
but
cot </span>θ=1/tan θ
thus to evaluate our vale we shall obtain the value for height since
adjacent=3
hypotenuse=5
thus
using Pythagorean theorem:
c²=a²+b²
hence
5²=3²+b²
b²=25-9=16
b=4
thus
tan θ=opposite/adjacent
tan a=4/3
thus
cot a=1/(4/3)=3/4
Answer:
220km per 20litre, so 220/20 to get 11km/litre
