Answer:
shading three boxes
Step-by-step explanation:
It is given that :
The body weight of an average adult = 60%
We have to show this by shading the square boxes shown.
There are 5 square boxes in total which makes up 100%.
So divide 100 by 5, we can 20% for each box.
So, 20% + 20% + 20% will give us 60%
Therefore, shading three boxes will give us 60% which is the water percent in an average adult's body weight.
This is represented by the figure below.
Solution :
Given :
X = homicide rate (homicides per 100,00 population)
n = 12 = metropolitan areas
Area X (homicides per 100,000 population)
Mesa, AZ 4.1
Seattle, WA 3.8
Portland, OR (tie) 3.4
New York, NY(tie) 3.4
Virginia beach, VA 3.3
San Jose, CA 3.1
EI, Paso, TX 2.6
Austin, TX 2.6
San Diago, CA 2.4
Suffolk County 2.2
Montgomery, MD 2.0
Fairfax, VA 1.7
Therefore, the mean of X = 

= 2.9
Therefore, the mean of homicide rater in the 12 metropolitan areas is 2.9 homicide per 100,000 population.
If the spinner is evenly divided then they all have a 25% chance
When you reflect FGH across the y-axis, you are left with the vertices of F'G'H at (2, -1) (-2, 2) (-4, -3)
The correct answer is b.
Hope this helps =)
Answer:
P ( X > 1800) = 0.1734
Step-by-step explanation:
Given:-
- The mean, u = 1497
- The standard deviation, s.d = 322
Find:-
P(X>1800)
Solution:-
- We will denote a random variable X that follows a normal distribution for the SAT scores in 2014 with parameters mean (u) and standard deviation (s.d) as follows:
X ~ N ( 1497 , 322 )
- The following probability can be calculated by first computing the Z-score value:
P ( X < x ) = P ( X < Z )
Where,
Z = ( x - u ) / s.d
- P(X > 1800) have the corresponding Z-score value:
Z = ( 1800 - 1497 ) / 322
Z = 0.941
- Hence, using Z-table:
P ( X > 1800) = 1 - P ( Z < 0.9471 )
P ( X > 1800) = 1 - 0.8266
P ( X > 1800) = 0.1734
