2) the imaginary part of z is 29i
Answer:
P(L ≤ l) =P (1-l ≤ U ≤ l)= l- ( 1 - l ) = 2 l - 1
Step-by-step explanation:
let assume that stick has length 1.Random variable L that make length of a longer piece and random variable U that mark point .See that L < l means that
U≤ l and 1-U ≤l
P(L ≤ l) =P (1-l ≤ U ≤ l)= l- ( 1 - l ) = 2 l - 1
this means 1-l≤U≤l
so we have
if we have L [1/2,1]
then apply the formula we have E(L)=3/4
The area of the composite shape in the diagram given is: 100 square inches.
<h3>How to Find the Area of a Composite Figure?</h3>
Area of a composite figure = sum of the areas of the shapes that make up the figure.
Area of the composite shape = 2(area of triangle) = 2(1/2bh)
Area of the composite shape = 2(1/2×10×10)
Area of the composite shape = 100 square inches.

Answer:
Interval scale
Step-by-step explanation:
In statistics, there are 4 types of measurement scales namely;
Nominal scales, interval scales, Ordinal scales and Ratio scales.
Now, in this question Cassidy is trying to research the impacts of eating breakfast on college students who have classes prior to 9 am.
This has to do with order as it deals with people who have breakfast before 9 a.m. It also deals with the exact differences in the various answers on the scale of 1 - 10 for each student student in the research for the 20 questions.
This is exactly what the interval measurement scale is all about interval scale deals with order and exact differences in values.
Thus, the scale used is an interval scale.
